Apple To Discuss HyperTransport For Future Macs
macrealist writes "CNET is reporting that Apple will discuss the use of HyperTransport in Macs at the Developer's conference. The interesting thing is that the article claims that Apple is not likely to use hypertransport to link the CPU to the memory, but instead to link chipsets together because IBM would have to 'to adapt it to the Power architecture.' But according to arstechnica, the 970 does have a frontside bus that operates at similar speeds to Hypertransport."
does not necessarily need to be used throughout the system. I can see where they'd use it to connect the two processors in a dual chip computer but let the front-side bus be something different. Though it is interesting that they picked the name "Smeagol" for the OS revision that allows thee 970 to be compatible, because the whole idea behind HT is to allow all the chips to speak the same language so nothing has to be translated from chip to chip. "One bus to bind them" perhaps?
Can hypertransport be used for inter-machine communication? What distance can it operate over?
Imagine a beow... of MACs?
"Taligent is still pure vapor. Maybe they'll be the last who jumps up on Openstep... "
... what I always wanted SGI to become. A cool hardware company with seriously good intentions towards the Unix world.
My next computer will be another powerbook, that's for sure... please continue to rock, Apple.

I have seen and read shedloads of things about ,how fast they will be and so on and so on.
thoses "G5" thingies, the Bus they will be using
So far I haven't seen anything about upgrades for older Macs.
If the bus systems are different, it means owners of olders Macs will be stuck at Bi-pro 1.4 giga.
It's not bad or even very good for the coming year or the next if you only do basic stuff. But after that what?
Is there a chance Motorola becomes a major suppliers of upgrade processors or will it be IBM boosting the G3 until it drops?
What do you guys think?
As many people (keep) saying, Apple kit isn't necessarily the fastest out there in terms of raw speed. However, from a day-to-day point of view, is raw speed what you want on a minute-by-minute basis? Probably not. If you do, then you've probably got a dual or quad processor x86 box churning away with your favourite SMP kernel-based OS. For everyday use (productivity apps, Internet, media manipulation) Apple kit does a really good job. Firewire is fast and convenient. More importantly, Apple kit (and software) is very stable in my experience. Apple looks like it is selective in its choice of cool new tech (tm) to incorporate into its products. This is a Good Thing.

I have been thinking of switching over to Apple, and now that many designers are coming up with cool products with OSX support, I am paying much more attention to Mac. I can remember back in the day when I first saw an Apple 2e, and I thought that it was so much better than my TI 99/4A, because of the games mostly. Oh and it had it's own monitor, and at the time I needed a TV for my TI. :)
I like the idea that Mac develops the hardware and software together under one roof. I think following the process from all angles like that would make for a better product. It's a better philosophy than the Windows/PC mish-mash way of thinking, primarily because no person sees all ends of the production for PC, and you can bet that there are quality issues with computability under PC that just aren't there with Apple (or at least that is what one would expect). So looking at Hyper Transport, at this stage, I'm a tad leery of it because it didn't come from Apple. I'm worried that it might have some kind of negative impact on the technology.
The necessary question is; is this going to be the next evolutionary step for Apple, or is it just an added hardware feature that is relatively minor?
Heres to hoping that the Hypertransport consortium becomes to Apple what the CHRP spec always promised to do. Common specs + multiple vendors (apple, amd and who else?) = cheaper prices for everyone. From what I gathered the first area we will see the hypertransport spec will be in connecting the PCI bridge and various components like that - not processor to memory connections. But that said, it seems to me Apple is really jumping on the right bandwagon here, anything that moves the platform away from this starved processor pc133 ram shit is in my opinion A Very Good Thing.
And yes i will be selling both my macs to get a ppc970 the day they come out.

With the Hypertransporter(tm) your computational dreams can come true.
First of all: A "frontside bus that operates at similar speeds to Hypertransport" most likely isn't Hypertransport - just like a car with performance similar to a Porsche isn't a Porsche. So you can't just hook up a 970 (or POWER/PowerPC) to a Hypertransport link.
Furthermore, linking a CPU to main memory via Hypertransport (a point-to-point link) means you can't share the memory with other CPUs (unless you have dual-ported RAM - uhh, yeah, good luck with that plan).

To the guy who modded me down from perfect to terrible Karma - Apple haters still suck
Apple has been a member of the HyperTransport consortium for over a year now. I believe the proper response to this "news" is "duh."
News for Nerds. Stuff that Matters? Like hell.
Yeah! I can't wait until I can transport my Mac through hyperspace! Now all we need are the flying bicycles!!

"Law & Order: Dead on the Money is an exiting 3D game. .
Exiting? Is this a foreshadow? Maybe they realized it sucks and are hinting at its demise.
This is a non-rhetorical question.
Why would Apple buy SGI instead of doing it all themselves? Like you say, in the long term, the OS and the current hardware and the sales organization would be punted. With the 970, Apple looks to be be developing the guts of a strong workstation/server technology on their own. Buying the customers and transitioning over might be possible, but would the (checks NASDAQ.com) $241M be worth it? Wait, $241M? That's all for all of SGI? Well then!
A few things I could see Apple wanting out of SGI:
Maya. Buying that and making it Mac only would be in keeping with all of Apple's purchases lately. Make a free rendering client for Xserve. It'd be neat
The sales organization. Given what SGI is facing in the market place, that they're still around and showing some revenue suggestions SOMEONE is rising to the challenge there.
Existing customer base. Buy the accounts. Make an IRIX compatibility layer for MacOS X.
Engineers. Presumably they've still got some good folks there. Apple could certainly use all the talent they can get in UNIX code, hardware design, etcetera.
I don't see much long term value in SGI's existing products if Apple bought them though, and Apple is certainly willing to give up market share on other platforms in order to make a package Mac-only.
Still, given that the whole company is only $241M, it seems like there might be something worth cherry-picking there.

Are you running a MacOS X box with Quartz Extreme? I'm writing this right now on a PowerBook G4 800, and the UI is nearly always as responsive as I could ask. Certainly, some applications like the Finer are slow, but heck, even when the whole Finder is locked, I can still drag a Finder window around perfectly smoothly, thanks to QE.

The new chips, rather than being laid out in a traditional manner, where there is a strict heirarchy in terms of data flow and hand off, etc., are said to be more like an large modern urban city, where there are pockets of industrial activity and zones for local administration mixed in with housing and recreation.
The new city has main roads that are rings (one or two), rather than grids where the government is focused in one area....industial parks in another.,...and families and fun parks all bunched up in yet another sequestered section. These ring roads serve to generally define city structure.
The dispersed control of new, very large cities is only possible by taking advantage of modern communication and thoughtful agreement to locallized authority.
When city government sits on a throne, and nothing happens without strict review and approval, a city can become bound up in red tape and suffer accordingly.
By applying this logic to chip layouts, the goal of rapid and coordinated decision making can become a more rapid and efficient process.
Let go of the frontside bus logic for a moment or two, and you'll perhaps see how this can be a leap forward, as opposed to an operational liability
For example, if I don't buy a SuperDrive-equipped box now, can I add one later? Are there any other things like this I need to be careful for that are "missing" from lower models? What are the architectural differences between the iMac/PowerMac and iBook/PowerBook? Is the rule about Quartz Extreme acceleration as simple as, "G3's don't support it, G4's do"? What min CPU would me to acheive "reasonable" speed for business-type apps under Virtual PC (only one or two apps I'll need there)?
Thanks.
