PPC 970 Powerbooks and Powermacs in Production?
Thadddius_Brinks writes "MacWispers.com
is reporting here
that apple is currently in production of a redesigned single processor PowerPC
970 Powermac system and a 15.4 inch Powerbook. They (MacWhispers.com) are also standing by
their earlier claims about the speed of the new processor."
This article consolidates many of the major rumors surrounding WWDC including
the rumor of a new case for the Powermacs, but it raises the ultimate question: 17" Powerbook, or PPC 970 Powerbook?
You heard it here first! ;)
I saw that as WWJD.. then I said to myself
"What would jobs do?"
it's only fitting, all things considered!
I am the lord of the pun. Dance Knave!
Egads this would be wonderful. 64-bit laptops. While I suspect we'll get that from the Opteron, I suspect if Apple follows through with the PPC 970, it will be available and useable much sooner.
Needless to say... drool!
With the entire Mac world abuzz with (often conflicting) reports of the Apple transition to the IBM PowerPC 970 processor family, we have decided to report a summary of all that we know at this time... not from regurgitated rumors obtained from other web sites, but from our own OEM contacts in the Apple supply pipeline.
We have no software information sources; all information we receive comes from people working in various positions in and around plants in Taiwan that actually supply parts or perform hardware assembly operations on Apple products. So, we have to leave the software speculation to sites such as Think Secret and, it now seems, eWeek.
What we know at this point is as follows:
- The IBM PPC 970 chips are now actually in volume production for only two specific end uses: IBM's own servers, and for Apple Computer.
- The plant contracted for assembly of the new Power Mac is now actually manufacturing production Power Macs with single PPC 970 processors.
- The plant contracted for assembly of the new 15.4-inch Powerbook has just now begun manufacturing production Powerbooks with the PPC 970 processor.
- The new Power Mac has a sister model with a 2-processor motherboard that is not yet in actual production, but that could be put into production at any time.
- The new Power Mac has a new case design with "metallic look plastics," and a front panel "mostly made with the same anodized aluminum surface" as the newest Powerbooks.
- The new Power Mac retains "handles," though not in the same form as the current design.
We have no sources or contacts within Apple Computer, so we cannot state that company's actual release plans for these products. However, we can say that both the new PPC 970 Power Mac and Powerbook will have substantial inventory already produced by the time of the upcoming WWDC keynote.
In closing, we want to address the performance of the new PPC 970 machines, as we do have direct information on this topic, and we consider that information to be highly reliable. Despite the recent flurry of confusing claims published by eWeek and others, we stand by our report that the new Power Mac and Powerbook have overall performance approximately 1.25 to 1.5 times that of a similarly clocked G4 on non-Altivec optimized applications. On Altivec optimized tasks, these machines have as much as 2 to 2.5 times the through performance as a similarly clocked G4. Our understanding is that this performance is occurring using bone-stock OS X 10.2.6 on pre-production single processor PPC 970 machines... an OS rampant with Rob Malda's homosexuality and none of the optimization now being rumored as being needed for supporting the PPC 970's performance potential.
Does anyone have any clarification on this? With the rumours that the 970 chip is actually less expensive for Apple than the G4 I was hoping for dual 970 boxes at price points similar to the current crop of PowerMacs.
Lasers Controlled Games!
1. That the 970's are being produced, but so far, there's still small numbers, so either only folks at the Developer's Conference will first crack, or you'll have to wait for a bit of time before you can actually get your hands on one (kind of like when the 12" and 17" first started shipping).
2. The major OS Upgrade to 64 bits will happen in a few more months - either way, I expect that OS 10.3 will cost another $50 - $100 (depending on how they do it).
3. The G3 iBook line will be slowly phased out, and replaced with G4 based systems.
4. Dual processor systems by Christmas or so.
5. iTunes for Windows sooner than we thought.
6. Somewhere in this timeframe, new Xserves will start to appear with the 970 chip and the 64-bit server operating system (which should be interesting for folks running "big ass" database/graphical rendering farms.
So either way, I'd say we'll "see" the devices, a few "first adopters" will play with them, pass judgement, Ars Techana [SIC] will write a big ass article on them, and "everybody else" will pick them up later.
Hopefully somebody can convince Valve that Half Life 2 would really run rather nicely on these boxes so I don't have to spend money upgrading my old Wintel Game Box.

If they release a 15" g5 powerbook, what would happen to sales of their 17" g4 powerbook? I don't believe apple would have a powerbook line with their midrange model having such a radically better architecture/processor then their high end model.
yes i run a goth/punk/emo porn site.
Isn't much more elegant to use hexadecimal?

Do you think the new "G5"s will sport new enclosures too..?
The current design is long in the tooth to say the least and is highly associated with the G4 processor... yet I've heard nothing about new enclosures at all..
Dude, RTFA:
"- The new Power Mac has a new case design with "metallic look plastics," and a front panel "mostly made with the same anodized aluminum surface" as the newest Powerbooks."
Its only one short page. Its not slashdotted (yet). How hard was that?
Sailing over the event horizon
Poor MacWhispers doesn't have a single ad on the linked site. Let's not destroy their servers when the article text is here.
I would have believed 970 PowerMacs in production but definitely not 970 based Powerbooks. That goes double because there's even more rumors of 15" Powerbooks based on the G4 but all aluninumized waiting to be shipped to Apple's stores and other retailers. If you've noticed there's a dearth of 15" Powerbooks in stock anywhere that sells them.
Besides June production doesn't mean a June release or even announcement date. Apple likes to build up stocks of computers before selling them. Building and shipping computers in the same month would be a ridiculous strain on their resources. As for a June announcement, see the Osborne computer company.
WWDC isn't exactly a place Steve Jobs likes to announce hardware products, it is really the wrong venue for such announcements. MacWorld Expo is a much better place to do things like that and is only two months away. It's not really a secret Panther developer previews are going to be released at WWDC which will likely be SJ's keynote subject. MacOS and related software ought to be and typically is the subject of SJ's WWDC keynotes. Not hardware announcements.
I'm a loner Dottie, a Rebel.
In another article on MacWhispers site (I believe) they mention information they've come across that appears to indicate a new enclosure will be used for the next PowerMac.
Long on the tooth the current one is however it's still far more attractive (to me at least) than anything available on the PC side. In my opinion at least the mirrored drive door model was a mistake and the previous Quicksilver was the best looking of the bunch.
The current one looks like someone gave a Quicksilver to some PC case-mod monkeys and they didn't know what to do with it so they glued a mirror to the front. It's the first one that looks like it's trying to be cool and the first one to (kind of) fail at it.

apple is offering sweet $300 dollar rebates to students, and they have just dropped the price on many models like the powerbook. might be a good time to jump on one.
My problem? I was perfectly gruntled, until some numbnuts came by and dissed me.
I'm no fan of Jack Campbell and honestly do not believe anything his site spouts. The only time I ever hear anything about it is when (semi-)legitimate news sources pick up "scoops" from his site.

I am not who I say you are.
Well, from past knowledge of how Apple has done things recently, I'd say...
PPC 970 Single 1.4 Ghz shipping July.
PPC 970 Duallies shipping within 4 weeks of the single.
OSX 10.3 Late August... and I would bet my kidneys you WILL have to pay for it (~$129), but don't moan... apparently there is a LOT of new/improved stuff, and this is only the beginning as Apple have found that they can build on the code very easily *indeed* due to the quality and clenaliness of it... exactly the problem MS seems to have with Windows ATM.
This sig has been deprecated.
Or the one in June 2000 that predicted that Apple was about to drop the entire PowerMac line and just sell laptops and all-in-ones?
Or the one in August 2001 that predicted Apple and AMD had collaborated on a "secret" CPU design code-named "Twostone", a 48 bit CPU with 16384 registers, that was going to replace the G3 and run it in emulation just as the PPCs had emulated the 68000?
Or maybe the one that, in September 2002, predicted Apple was about to release a cordless phone, FOR NO REASON WHATSOEVER.
I hardly would describe them as a dependable source of unfounded rumours.
Other than the 17" my friend has and the ones I've seen at two Apple stores and a Fry's I haven't heard of any 17" Powerbooks shipping.
I'm a loner Dottie, a Rebel.
I find it hard to know what to believe here. It seems a lock that Apple will introduce PPC970 based Macs at WWDC, but the question as to when they will be availble for shipment is something that is probably only known to his Steveness.
As far as a PPC970 based Powerbook goes. I doubt it. The peak energy consumption is low enough, but I don't think it has any powersave features built in. The increased complexity of a whole new chip in a laptop...seems dubious.
However, There is one thing that makes me think a Powerbook G5 might be released: Apple has not updated the 15" Powerbook since November, not even to bring it up to feature parity with the 12" and 17" models (Bluetooth, FW800, and DDR memory, Aluminum enclosure). It does make me think that maybe Apple has been waiting for the next major uprade to update the 15" models and switching to the PPC970 would certainly qualify.

I'd like to see some real competition for high performance CPUs as much as the next guy, but let's not lose our heads to con artists like this guy...we will know for sure in about 2 weeks
(-1, Raw and Uncut is the only way to read)
Everyone's immediate reaction to MacWhispers is always negative.
"Oh, I'll believe it when I see it."
Obviously. MacWhispers has given up on making release date predictions. You'll notice that they have *not* given a specific timeframe for the release of these machines. They have said that they are being built.
So, now, when WWDC makes no mention of the 970, everyone will say "See! MacWhispers are a bunch of damn fools." and no one will remember, two months from now, when these machines surface, that it fits perfectly with MacWhispers' information.
If you take them completely literally, they are a valuable source of information. They cannot divine the future, and they don't seem to be trying to do so, either.
There are no trails. There are no trees out here.
Without knowing exactly how many PPC 970 chips are being produced, it's tough to guess where they would go in Apple's lineup. If there are enough, it's safe to venture a guess that:
1) PowerBook gets the yummy new PPC 970 chip (it IS the year of the laptop afterall)
2) iBook then gets the current G4 chip. The last of the lineup using G3s finally gets the upgrade.
3) iMac, eMac, PowerMac get new 970 chip because hey, we can't leave them out. Or can we? It's the year of the laptop...maybe let the masses go nuts over the laptops as they continue working on the new IBM chips and then blow the doors off when they're ready to be put in the desktop models.
"He uses statistics as a drunken man uses lampposts...for support rather than illumination." - Andrew Lang
Specifically:
Unlike the G4, where the AltiVec unit is integrated rather nicely into the issue unit, and can issue several types of vector instructions in parallel, the 970 can only do a permute in parallel with another instruction. Hence, for some tasks, I would expect the G4 to be almost twice as fast as a similarly clocked 970.
They make a similar claim about the non-AltiVec speed, which I tend to believe. The compiler has to be a little smarter (but Apple did add a bunch of G4 optimizations to gcc anyway), but the 970 can do more per clock the the G4 can, under many circumstances. Not only can it have more instructions in-flight, but it has a much more advanced reordering unit than the G4.
Oh yeah, and when did /. just copy over Apple rumor stories? </obligatory>
Yes, I'm still a junky. Are you still a bitch?
I haven't looked but do you get an equal number of PC rumour sites if you go Googling for that?
If not then you've got to ask yourself why is it that so many people care about what may or may not be coming along next from Apple and so few give the proverbial rats ass about the next offering from HP, Dell, or eMachines.
Apple seems to have perfected getting attention to an art. You can love them or hate them but almost nobody ignores them. That kind of PR is priceless.
Appended to the end of comments you post. 120 chars.
It's actually called the PPC980, and is due next year.
Yes, the PPC980 is in the IBM roadmap, it's to the Power5 as the 970 is to the Power4.

I think that at this point it's quite obvious _something_ is in production, but that doesn't mean the time frame you can by an updated Mac is close at hand though.
Major changes that effect developers will be announced at WWDC. It's likely that whatever new directions in CPUs, APIs, or Market segments will be announced there because developers will have to react to the news. That doesn't mean anything will be available for sale or even that we'll get the whole picture of what cases, prices, user interface changes, or iApps will be released. Not only don't developers need to know this stuff, but traditionally they've been a very conservative, non-spontaneous, purchasing crowd where such surprises would be wasted.
People keep talking about having the whole Mac product line refreshed at WWDC and nonsense like that. My guess is far more conservative. We may get a timetable to expect new PowerMacs, but we probably aren't even going to see the new machines in final plastics.
During the transition from 68000 to PowerPC, Apple bent over backwards to give developers access to emulators, test labs, and even loaned machines to big developers. But they didn't start commercially selling anything until eight or nine months after the WWDC announcements.
I don't think Apple will wait quite that long to introduce new chips if such plans are really on the horizon, but I think there will be some non-trivial lag from WWDC to new consumer-marketed debut of new hardware.
OK, my predictions:
I don't read ACs: If a post isn't worth so much as a nom de plume to its author then I wont bother either.
Assuming you aren't memory bound. You've only got 166 Mbps TOTAL between the two processors, which well tuned AltiVec codec can saturate with a single processor, let alone two.

"I hardly would describe them as a dependable source of unfounded rumours."
What are you trying to say, they are a great source of unfounded rumours! Not to mention dependable!
A fool throws a stone into a well and a thousand sages can not remove it.
I don't get why its believed that Mac OS X has to be 64-bit to run on the 970. We've been told in numerous places (Ars, IBM's frickin website) that the 970 runs in 32-bit just fine.
SO... that being said... my WWDC announcment predictions along with what Apple has already stated
- New Macs with PPC 970
- New PowerBook 15 with PPC 970 (the 15" PowerBook is the workhorse of the line, always will be, sorry)
- Preview of Panther
- Macintosh Roadmap Roadmap showing the future... and this is the big-ass news that everyone's been talking about.
Roadmap steps will look something like this...
July 2003:
10.2.7 running on new 970-based Macs practically unmodified because the 970 handles 32-bit operation just totally fine. x.x.+1 updates between WWDC and October 2003. Developer-only release of 64-bit SDK which will not be ready for prime time, but will allow developers to make the swtich, if necessary (similar to Mac OS 9 -> Carbon transition)
October 2003:
10.3 release - all those cool updates in iApps, updates in performance and operation of Mac OS X UI that were shown at WWDC. Panther Will NOT BE a 64-Bit OS!! - why not? Does not need to be because there are no 64-bit apps! Where are the apps? They are still being worked on with the 64-bit SDK, see you at Mac World San Fran with first 64-bit apps.
Jan 2004 (MWSF):
10.3.5 release. Mac OS X will run 64-bit applications. Only apps that NEED to be recomplied 64-bit clean will be recompiled 64-bit clean (iChat, for example, does NOT need to be 64-bit). Finder will be first app to be 64-bit clean because it needs to be.
beyond that, its non-speculateable.
But i think that the real news at this WWDC is going to be the first major Macintosh Roadmap since we saw the Rhapsody one in 1997(8?). You will see where the Mac is going hardware-wise and software wise.
Apple is going to push into the small-medium server market in a hard way.... 64-bit XServes which can run horkin Oracle databases, huge fileservers, and be the backbone of big-ass renderfarms... all with Mac OS X moron-simple UI and none of the pain of cost with Windows servers or admin headache of Linus servers? Puhlease... Apple is going to kick ass and move in where Intel and AMD are just simply lagging behind.
(yes, half the guys in my wedding party have apple.com email addresses.. no, none of this information was gleaned from them.)
guns kill people like spoons make Rosie O'Donnell fat.
The PowerMac G5 will be announced at WWDC, based on the IBM PowerPC 970. The name of the machine will be "PowerMac G5" or "Power Macintosh G5", but Apple will also advertise the processor as the "IBM PowerPC 970 processor with Velocity Engine". It's 64-bit, and they'll hype that up as much as they can.
The low-end (1.4GHz?) model will be available immediately, or within two weeks and Apple will be taking pre-orders. The mid-range and high-end (dual 1.6 and dual 1.8?) models will be shipping within a month after that. Photoshop comparisons with the latest Compaq PC will be mind-blowing, for the types of people who get excited about Photoshop performance. USB2, Bluetooth, FireWire 800 and 400 and Gigabit Ethernet will be standard features, with a slot for an Airport Extreme card.
The Aluminum 15" PowerBook will be released. We will not see a PowerBook G5 before January '04 and maybe not until March '04.
The PowerMac G5 will ship with a hacked version of Mac OS X 10.2, which will not be fully optimized to take advantage of the new processor. However, the PPC970 is designed to run 32-bit code just as well as 64-bit code, so it will still be amazingly fast. Anyone who buys a G5 will be entitled to a "free" ($29 S&H) upgrade to Mac OS X 10.3, which will ship in September for $129.
The new OS will be 64-bit native, optimized for the PPC970, and compiled with gcc 3.3. Large chunks of the Finder will be rewritten for performance and better UI, and there will be a ton of little system-wide UI improvements (adding up to a significantly better experience). One convenient new feature will be support for multiple users being logged in locally at the same time, like Windows XP (go to a login screen without quitting all your apps, second person logs in, first person's apps stay running hidden in the background, can switch back and forth between users).
Mac OS X 10.3 will include WebCore, Apple's Aquafied version of KHTML, available for any application to use. Safari will be the default browser. I suspect Internet Explorer will not be included, although of course you can download it from Microsoft. Help Viewer will be replaced (thank god) with a version that uses WebCore. Now that WebCore is available, it'll be possible for Apple to support PAC and WPAD for automatic proxy server discovery, although I don't know whether these features will make it into 10.3.
Did I miss anything? We'll see how accurate my predictions are next month...

Ways of knowing Apple is going to release something.
1. Supply chain starts drying up.
2. Apple allows upgrade makers to catch up.
On the supply chain i've heard conflicting rumors, but on the upgrade side both OWC and Powerlogix have now released 1.42Ghz upgrades, this matches the top of the line G4 desktops.
So there is definitely SOMETHING coming, whether it is a new 970 based machine or simply speed bumped G4's only time will tell.
Mac had better come up with a dual processor Notebook.
'Mac' would do bloody well to come up with *anything* considering it's a product name and not a company... have a lot of experience with Apple products do you?
I am demoing a shoebox AVID field editor that has 2 P-4 processors
I think you mean 2 P4 Xeon processors seeing as vanilla P4's are not SMP capable, and you are probably paying through the nose for this privilege, and it's likely not gonna be anywhere NEAR as portable as a notebook so you're not really comparing like for like are you?
Current Apple notebooks compare rather well in both price and performance (and ALWAYS in functionality) to modern PC notebooks. Show me a PC notebook with dual processors? The performance delta is negligable on the notebook front, unless you're thinking about the companies who put desktop chips into their PC notebooks, and then you had BETTER be able to do your work a lot faster because you've got 15 mins of battery life on the thing. Show me a comparable machine with a 17 inch screen, 4.5 hour batt life, gigabit ethernet, superdrive, in an enclosure as portable as the Mac at a price not far from the Mac.
MAC's used to be the thing for Video....
Hmm, strange, I never knew that Media Access Control was so capable it could entirely take the diverse strains of Video PP. The abbreviation for the Macintosh platform is Mac, not MAC, this error really pisses off a lit of people and shows the poster as ignorant, someone in the industry would have known that I would have thought.
it looks like they are starting to lose with the big companies moving away from them...
What a gem of wisdom... you've wonderfully neglected to mention any of these companies you refer to... unless you mean your own, which judging from your post has never/rarely touched the Macintosh platform seriously.
Go find somewhere else to post your FUD, Troll.

By far the biggest advantage of the 970 is simply that it's a much faster processor than the G4. If it were only 32 bits there would still be a good deal of anticipation. I doubt we'll see Powerbooks with 32 gigs of RAM anytime soon, but a PB 970 would still be a kickass machine.
How to solve most of our problems: 1.Lots of nuclear plants. 2.Cure aging.
using bone-stock OS X 10.2.6 on pre-production single processor PPC 970 machines...
This statement casts doubt on the other claims of the article because it is simply not possible. A 970 Mac could not run stock 10.2.6 as it exists now because it doesn't include drivers for the 970, the new Hypertransport bus, or the new motherboard chipset. IBM stated that only minor changes would be necessary to operating system code for 970 support though, so my analysis is that there are two possibilities.
Either a. the OS they are running isn't stock 10.2.6 but a modded version that is being called the same thing
or b. there are no running 970 Macs as of yet so they aren't running any OS.

A programmer is a machine for converting coffee into code.
I do belive that Apple will have some sort of 970 based machine for the developers to look at, as well as some benchmarks for us all to drool over.
So what can we expect? Previewing Panther on a 970 based system, probably an update to the developer software (64 bit Project Builder), benchmarks of the 970, overview of 970 based hardware. Probably annouce a PPC 970 based Powerbook in the near future...END OF YEAR? Possibly a Naming change to hardware lineup, and Adjustable Displays
What is less likely? Windows verison of iTunes, PPC 970s shipping, PPC 970 Powerbooks shipping, iCam,
What is NOT going to happen? Apple PDA, Apple Cell phone,
As for the whole product line being revamped, i don't think we'll see a whole new product line at WWDC, but i think that Apple is going to be moving all it's lines away from the G4/G3 based systems. I don't even see the iBooks being converted to G4 systems, as IBM's chip lineup is known to be 20-30% cheaper than Motorola's line...
Instead of seeing G4s as the low end chips, i'd probably wager that IBMs will develop a PPC off of the 750 chip and this will probably replace the G3 systems. But i wouldn't expect to see a PPC 750 until you see a 980 in a powermac.... I think if Apple is going to IBM processors, it would be prudent that they went to an all IBM chip lineup.
They wouldn't be supporting two operating system, it's the same operating system!
64-bit PPC architecture can run 32-bit PPC code just fine as-is. Which is part of the reason that there are claims of stock MacOS X 10.2.6 being run on these PPC970 machines.

Apple can waffle on about the Mhz myth all they want, but I don't see them REDUCING clock rates generation after generation.

...at least at our house. The old Performa is very happy with Debian, and the Umax dualie is good with NetBSD. And the iBook SE we used to have was mucho smooth under OpenBSD.

Which flavor is best for your aged box that's not up to snuff for OS X depends on it's architecture and your needs/experience.

We'll prolly wait on the 970 before buying another Mac. In the meantime our new cheap Intel mobo tower runs XP and Knoppix on the HD (reiser FS) just fine, on the metal or under VMware.

The cache certainly helps a lot for stuff that can fit in the cache, but for "streaming" tasks, where data is read, processed, and output without being reused, you rapidly hit against memory bandwidth. Well optmized video code definitely runs out of cache quickly.

So, you're claiming that the 32- and 64-bit versions of Solaris, AIX and FreeBSD are entirely *different* operating systems? Because you're currently claiming that a 64-bit version of MacOS X is a seperate operating system.
Adding a kernel profile for a PPC970 is *not* creating a new operating system. Adding 64-bit support in the OS is *not* creating a new operating system.
And your claims that the underlying hardware is "different" are as valid as saying that a 486 and a Pentium are "different hardware". Granted, they're different chips, but they share fundamentally the same roots. Just like the current G4 and the PPC970. Remember that the PPC970 is 100% binary compatible from an instruction point of view and will run *any* G4 code without modification.

I think PCs do get equal attention, but since all the parts in Dell's, HP's, etc. machines are all industry standard parts manufactured by other companies, the speculation isn't about their offerings but the offerings of their suppliers.
There's a lot of speculation about AMD's chips, or new motherboard chipsets, or nVidia or ATI's new graphics cards -- probably just as much or more in total as that which surrounds Apple's products. Apple just has a lot of relative speculation surrounding it since it's the only provider for a particular platform.
" well, I've read some moderately convincing arguments that - because of the low latency, 4GB/sec L3 cache that the current top end G4s sport - memory bandwidth is not the bottleneck that we'd all like to believe. It seems that the REAL bottleneck is simply the low clock speed and lack of integer and FP execution resources that the 7455 has available."
The only problem with that argument is that the bus tops out whenever you're churning on a large dataset.. like video editing...
There's no doubt that the L3 helps, but actual memory bandwidth would help a whole lot more.
Holy crap - this whole discussion is en re a MacWhispers column written by a guy who's time and again (macTable; envestco, etc.) been proven to be so full of shit his eyes are brown.

It wouldda been good to see evil carrot's post further up the thread
If it is for real, great - considering the source, though, doesn't fill me with hope. The article was convincing with all the "inside scoop" from the part OEMs -
Oh, well - I just bought a dual 867 anyway
Interesting that lost in this all, without comment, is the irony that IBM, which once represented all that was opposite to Apple and was its big nemesis, will now be the heart of the latest, greatest, user-friendly Apple computers, and that's viewed by the Apple community not just with anticipation and excitement, but with a sense of impeding vengeance, even, against ... what? Still, the IBM-compatible PC!
I can do that with a Firewire-equipped camera and a PowerBook with Final Cut Pro on it.
This is dependent on your production environment using DVCAM or (for low importance work) DV or MiniDV since all the pro DVCAM and consumer cameras have firewire ports. If the camera has an I/O firewire port (some have out only due to a silly tax law defining it as a VCR if it has external video inputs), then you can master back to DVCAM and have the tape ready before you even get back to the office.
Nothing Apple makes at present has component inputs, for that you need Media 100i, which has a breakout box with assorted inputs including component, SDI, AES/EBU etc depending on how much you want to spend.
We have a Media 100 system and a Final Cut Pro system. Both have strengths and weknesses, but for a program I can pick up for under £1000 and install and use on a Dual 450 G4 (our current FCP system), Final Cut Pro compares very favourably to Media 100.
If you're using Betacam then you're limited to expensive NLE's anyway - either Media 100 or Avid, and I've found that I prefer using Media 100, even if it is a bit slow in the render department. The PPC970 should help there.
