" According to ArsTechnica's report, Altivec implemantation in the 970 is supposed to be rather worse than in the G4"
Well, it depends what you mean by "G4". Apple has called ALL of the Motorola MPC 74xx series chips it uses "G4s", but all MPC 74xxs are not equal in the Altivec dept. some support L3 cache, and some don't. Ars said that the Altivec implementation in the 970 is very much the same as that found in the early G4s, the MPC 7400 and 7410 - the current G4 (the 7455) has a substantially more powerful Altivec implementation. Either way, the higher clock rate and larger memory bandwidth of the 970 should give it a pretty hefty boost over the last of the MPC 7410s (which ran at 533Mhz with a slow, large backside L2 cache).
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. Apple can waffle on about the Mhz myth all they want, but I don't see them REDUCING clock rates generation after generation. The PowerMac G4 has a fairly promising overall system design, but it doesn't offer ATA 133, 66Mhz PCI (though it's long supported 64bit PCI), USB 2.0 or AGP 8x.
Apple would have you believe from their data sheet that it's a "balanced" design in the mould of an SGi Octane. It isn't. It's not bad, but it should be GREAT.
Hang on a minute. Bus speed is 167Mhz, bus width is 64bits. 8 bits still equals 1 byte, right? So that's 8 bytes per cycle, 167 000 000 cycles per second, my maths make that 1.24Gbytes/second. Much crappier than the current Athlon and P4 designs, for sure, but a lot more bandwidth than you're talking about.
"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."
I couldn't agree more. My home machine is a DA 533dp (and hence, a graphite El Capitan case) but I'd love a QS in it's place - they just look so GOOD.
What? Little old primetime, international hit Will and Grace? You're fucking kidding me! At this rate, you'll be telling me that Friends isn't shot on MiniDV!
Here's a clue for you, arsehole, MOST post production work doesn't have million Dollar per hour budgets. Are you fucking stupid, or what?
Tell me again how important Inferno is to the majority of post production work? Of course, a dreamer like yourself probably thinks those little making-of documentaries that you watched on your Minority Report DVD represent what actually happens in the real world. Why not pick another industry to pretend that you know something about? You might get a better hit rate.
$100K for a fucking Media Composer set-up! Not any more, pal. Jesus, even an Editbox doesn't cost that these days. You clearly neither work in post, or know fuck all about post equipment. You can online for broadcast for less than £10K these days.
Systems like Fire and Inferno are irrelevant to 90% of broadcast work.
What are you blathering about? Care to flesh out the bullshit?

In the UK, 3Gs data speeds aren't any better than GSM/HSCSD/GPRS, which is what I currently use with my Palm Tungsten T, Nokia 8910 combination. Bluetooth lets you live the dream! (well, it let's you pick up and send email)

you're absolutely correct (I bought SoundJam 1 week before iTunes was released - d'oh!) though I also thought that Audion can do it - I'll have to go and check.
Audion is a really great encoder if you uise Mac OSX, by the way.
it might - even a properly anti-aliased and dithered resample/decimation is gonna give SOME artifacts, and the AAC encoder will have to deal with these.

so you think the 1Ghz G4 notebooks aren't cock-meltingly hot?
they fucking well are, mate!

anology?
dont?
that's pretty lame
the pre-release RC5-72 is Altivec optimised, and is just as fast as the old RC5-64 client.
I've been using it for ages, and it's at fc stage now.
