Default Cebit 2005: ATI R520 "Fudo" twice as fast as X850

http://www.techpowerup.com/reviews/Cebit2005/Day4/5
ATI R520
ATI's new GPU chip R520 is internally called "Fudo". The design has been
ready for quite some time now. One source is telling us "the chip is
working, now ATI is designing the boards, and after that they have to fix
the boards to get them working [laughs]".

The chip is produced using a 90nm process at TSMC and will have 300 to 350
million transistors.

We have confirmed the 24 pipelines rumors from several independant sources.
However, these 24 pipelines are not comparable to 24 of today's pipelines -
multiply by 1.3. So the 24 pipelines will have the performance of 32
"normal" pipelines.
The result of this is that the R520 will be two times as fast as the
currently fastest X850s.

ATI will most probably present the chip in June at Computex, Taiwan.

The most important architectural change is support for WGF 1.0 (Windows
Graphics Foundation). This is the successor to DirectX9, often called
DirectX Next. WGF will be included as standard in Microsoft Longhorn.
WGF offers new exciting features for game developers like "unlimited" shader
length, Geometry Shaders, Much lower overhead than DirectX9 and many more.

Obviously ShaderModel 3.0 is supported by R520 as well.

Memory configurations will be 256-bit memory interface (definitely not
512-bit) with 256 MB and 512 MB GDDR3. The internal registers of R520
support even 1GB memory size. With current GDDR3 prices we will definitely
not see a 1GB design at least not in the near future and not for gaming
cards. However, this shows that ATI is planning for the future.

The boards will be available in PCI-Express only. When asked about an AGP
version, one source said "most probably not". Please note that this is not a
definite "no". My guess is that if the market really demands an AGP version,
it will be implemented via the Rialto bridge chip.

In the S3 part of this report we talked about OmniChrome supporting
10-bit-per-color display depths, so does R520. HDTV and HDCP output will be
supported as well.

Clocks are not finalized yet, but expect something around 700 MHz core and
800 MHz memory (1.25ns).

The first boards will be VERY expensive people are talking $600-$700 range.
It all depends on how the graphics memory prices develop in the next months
and if TSMC can get good yields out of the 90nm process.
