NVIDIA GeForce 9800 ~ G92: over a billion transistors, 512bit memory bus ?

NVIDIA 9800 Series Coming Soon
Date: 2007-9-17


The GeForce 9800 series of graphics processing units, GPUs for short,
are based on the video processing chip codenamed G92 that is built by
the Taiwanese contractor TSMC, using the 65 nanometer fabrication
process. The complex architecture of the graphics chip and its
capabilities are responsible for the fact that the G92 has over one
billion transistors within. Going further than the 8800 series, Nvidia
implemented in the G92 chips the second Generation Unified Shader
Architecture as well as doubled precision support in the form of the
FP64 technologies. As graphics processing units are now known for
their parallel computing capabilities, the manufacturing company
decided to make good use of them and integrate the GPGPU as a native
technology.

Talking about parallel computing capabilities, well, the G92 GPU will
hit the one teraflop mark with its shader processing units that comes
in a MADD+ADD configuration which translates in 2+1 FLOPS=3 FLOPS per
ALU (the shorthand for the arithmetic logic unit). The fully scalar
design of the G92 series of GPUs is combined with a 512bit wide memory
interface and an extended support for as much as 1GB of GDDR4 graphics
memory. Graphics APIs supported are represented by the latest (in fact
not yet released) DirectX 10.1 and its open source equivalent, OpenGL
3.0. Other new features of the G92 series are the support for "FREE
4xAA", an audio HDMI compliant chip, a tesselation unit built directly
into the graphics core and improved performance and quality output of
the AA and AF units.

While pricing for the GeForce 9800 series will vary wildly across the
different manufacturers, two price ranges are being shuffled: 549-649
USD for the GeForce 9800 GTX and 399-449 USD for the GeForce 9800 GTS.

Seems as if this information may have been hashed together from
wishful thinking in combo with leaked technical information on
prototype work for nVidia at TSMC. . This description is highly
unlikely to be that of the upcoming G92 (November).

Remember that there is at least one key missing part-number in the
G9x family, and nVidia hinted in an interview about 6 months ago with
(afair) "The Tech Report" that one of their new-gen GPU parts would
have double-precision data-paths to fully accommodate its dual
application roles as GPU and GPFPU. So something is likely to come
along with specs along the lines stated above, but not just now......

nVidia is VERY keen to replace the G80 GPU ASAP with a much faster
successor with some useful tweaks (HD-decoding?) and a LOT LESS DIE
AREA..... lower cost, far better yield and at a board-price at or less
than the 8800GTS for performance greater than the current 8800GTX...
afaik, the real G92, not the above wishful-thinking-collected-together
speculation. Boards based on the (real) G92 are very likely to
wipe out the HD 2900 as a competitor in the same price-range and with
performance more than matching the needs of current Dx10 games (think
Crysis) at a reasonably modest price.

The very best (and far, far more expensive with much lower sales
volumes and no necessarily exclusively for the desktop PC market ) is
yet to come.....my guess Q1/Q2 2008.

NVIDIA 9800 Series Coming Soon

I do not care. I am happy with what I have now (a 7-series card). It
is enough to play the latest games at full or close-to-full settings.

In 1 year, I will be able to buy 8800GTX for $200... which sells now
for $800, so that I will be able to play the latest games. Thanks to
the new 9-series.

That's what a lot of us are hoping that they will do...

I shall be very surprised if they do NOT grant your wish around
mid-November. Remember that Crysis hits the street ~ November 16.

The loud sounds of many cash-registers ringing. If they do satisfy
your wish, the demand is likely to be so great that I suspect there
will be as shortage of the cards through Christmas.

My 7950s are kicking the 8800s butt in every benchmark.

what benchmarks?

what benchmarks?

The number of sevens and fives in the product name?

Hmmm, what 7950 and what 8800's?

You mean these?
