...but later on I read this...

""Intel CPU :

Up until the very last minute, the Xbox was scheduled to use an AMD CPU but Intel stepped in with a price Microsoft couldn\'t refuse and AMD refused to match. In retrospect, this was probably a mistake by AMD. Back then, no one would have predicted the CPU price war or tech slump and even if AMD was selling CPUs at break-even prices, powering Xbox would have given them a nice marketing boost.
Even so, the past can\'t be changed, and the Xbox is possibly using a Celeron CPU. The Celeron bit may surprise you since many of us assumed it would be CuMine after Microsoft explained that the Xbox CPU would be "based on the Pentium III Processor." According to EE Times, the Xbox CPU only had 128K of L2 cache. Still, Intel marketing representatives have suggested to FiringSquad that the chip may have been upgraded to a Pentium III processor with 256K of L2 cache.

If you recall, the 3D geometry calculations will be done on the XGPU, so the PIII\'s FPU performance won\'t a big issue. Still, even with T&L hardware, a faster CPU results in faster framerates. The main CPU is still in charge of game logic, physics, opponent and NPC artificial intelligence, and managing memory. At the 640x480 the Xbox is likely to remain in, a faster CPU could have significant performance differences. A 1 GHz P3 offers 15% higher framerates than a 733MHz P3 in Q3A.

If the CPU is a Celeron CPU, it will be the most significant flagrant technical flaw in the Xbox design. As we\'ve shown at FiringSquad, AMD\'s Duron completely destroys the Celeron. If the CPU is a Pentium III, then the Xbox will be in better shape even though 1 GHz would have provided a faster system. We\'ll have to wait until November for the final answer.""

November for the final answer ?  so...the final specs are still not confirmed ?  What do you know about it ?

It\'s your average run of the mill Celeron processor...

Just look at the cache on the xbox, and on the PC versions..that simple:)

if this is true...dumb asses!
celeron? doo-doo outdated chip!

with cheap amd chips hitting upwards towards 2ghz this holiday....maybe i\'ll just build a fresh computer and nab warez for free.

a joke.

watch out, Aaron is going to close the thread!

ugh, just joking Aaron, your still one of my best buds

Ops...I\'ve found an error...

The Xbox CPU\'s L1-cache is 32KB...also, there\'s talk about upgrading the L2-cache to 256KB !

No final hardware?
YET??

MS must remember that Xbox lanuch is only 2months away..
So this means they havent started production YET?

No more changes will be made, Xbox production started a week ago.

MS could be keeping low key about it, but its highly unlikely. The Xbox is still a very capable machine, I wouldnt\' worry about it.

Some fanboy started this UP. It has been a p3 since day one. That has not changed the only thing that has changed is the drop in speed from 250-233. And the speed could have always been 233 ms just  chose to wait until the very end to tell the fans. That is a normal corporation move.


it is 2 months away from launch if you think the specs are not final yet then your crazy. That would be stupid. Ms is a big corporation and they are not stupid. I mean these companys no what they are going to do long before they tell us. Bye the time they let the public no it is months after everything is done.  IF THEY where using a celeron they would have said it when they finally told fans about the gpu speed. Because the p3 only handles small operation which is barely nothin. The gpu is where the xbox gets it\'s power.

So if the it was a celeron they would have said it a long time ago because it would have made no sense to hide this because the cpu basicly does nothing in the xbox.

There is one other major change.  When they announced the X-box, they said it would run a 1Ghz P3, then later dropped it to 733 Mhz

No they didn\'t... It started off as 600-somethin\' mhz, and was raised to 733mhz. Then a couple of months later, rumours started flying around that the processor would be raised to 1ghz(Some have said that MS started that rumour... Why would they? ).

The 2 GPU drops, and the CPU increase were the only changes made to the Xbox hardware... Oh! And that Hyper Transport Technology was put in too, I guess we could kinda sorta consider that as a major change.

You understand nothing about Hardware !

The Power of the X-Box comes from every piece of hardware=The P3,The NV2a,the MCPX,the whole architecture ! The P3 has to do calculations about phisics,AI,collision-system,etc and the fact that the large majority of floating point work performed by the Xbox will be done by the NV2A graphics processing unit  doesn\'t mean the P3 basically does nothing in the X-Box ! The P3 is a very powerful CPU considering the Tasks it has to do...

...please...the next time...post if you have something interesting to say...thanks
