Xbox 2 Specs Leaked * Update *

"Mercury News has just published an article revealing the Xbox 2
specs. You can view the entire article here.
We had access to some speculative Xbox specs last month but we have
held off on revealing them until more official word is given. Now that
someone had the balls to do it, we'll bring you even more details
based on the info we have.
Please remember this info isn't official and based on info from
various sources. As the Mercury News article says, the Xbox 2 will use
three 64-bit processors. But we'll give you even more details. They'll
be PowerPC processors, based on the PowerPC 976, the first dual-core
97x chip based on IBM's 64-bit POWER5 architecture, which will also be
the first PowerPC built on a 65nm manufacturing process. Check our
previous story for further details.
Each processor is capable of processing two threads, thus meaning the
whole system can process six threads simultaneously. It is worth
noting that, because of its RISC nature, the new architecture is a
big-endian system, a term that describes the order in which a sequence
of bytes are stored in computer memory. Traditional x86 architectures
use the little-endian approach.
The Xbox 2 is a multiprocessor-enabled, 64-bit platform. It is a
proven server architecture that, in the case of Xbox, won't take
advantage of the greater than 4-GB physical memory space benefit of
64-bit computing but will make use of its other benefit: wider data
paths and registers, something extremely useful in the execution and
process of both integer and floating-point calculations.
The Graphic Chip
The graphic chip will be based on the the R500. This VPU has been in
design at ATI's Marlborough, Mass. office. It'll be fully compatible
with DirectX 9 PS and VS 3.0 and the next version of DirectX: DX10,
the same suite of APIs that will be used in Longhorn.
What nobody is telling you and you'll know about this first, here on
TeamXbox, is the revolutionary approach of the Xbox 2 to deal with
today's biggest problem in graphics chips: memory bandwidth.
The graphic chip will contain not only a graphics rendering core but
up embedded DRAM acting as a frame buffer that is big enough to handle
an image that is 480i and can be 4 times over sampled and double
buffered. Yeah, we all remember Bitboys but this time you can bet this
is for real. This solution will finally make possible HDTV visuals
with full screen Anti-Aliasing on.
The technology also supports up to 512 MB of external memory on a
256-bit bus. However, current specs plan to use 256 MB RAM, big enough
for next-generation visuals which are all about computational power
rather than large storage.
We'll have more on the Xbox 2 specs soon. Stay tuned. We'll update
throughout the day.
** UPDATE **
Information or Disinformation?
Don't believe everything you read. This is certainly the case
regarding a lot of speculation that is currently flying around
regarding the specifics of the Xbox 2. However, by collecting various
bits of information it is possible to establish a few more than
possible predictions of what is to come. Many have been discussing the
rumors that the Xbox 2 will lack a hard disk, but this may not
necessarily be true. Others have also been saying that a waiting game
is being played between Microsoft and Sony, in which one side is
merely waiting to see what the other does before making a decision.
Again, this is most likely not true. Both companies are sure to have
pretty solid ideas of just how they want their console hardware to be
designed. Many of our questions are more likely than not already
answered, and the question that remains is when will these facts be
officially supported by the designers.
While we can't give you any official information, we can give you a
hint based on what we have come to know by deductive reasoning. Do you
physically need a hard disc to store content? Consider this; in the
case of Xbox Music Mixer, do you need the files to be stored in your
Xbox? Answer that for yourself and you might just have sufficient info
to put this question to rest…at least for now.
It may also be a false claim that the Xbox 2 will not be backwards
compatible. Well, sort of anyways...
The fact is that Xbox 2 could be backwards compatible using emulation.
Microsoft already owns VirtualPC, which allows PowerPC architectures
to run Microsoft Windows applications. However, the problem is that,
although Microsoft owns the DirectX API and the Windows kernel, it
doesn't own the nVidia chips found in the Xbox and since it is
changing it graphics partner in favor of ATI, there are almost no
chances of an agreement between the two companies being reached. This
is more of a business problem rather than a technical issue."
