Certain Graphzilla minions kept on hyping the G92 as the best thing since
sliced bread and a new performance leader, while G92 is now marking a mainstream
chip. Mainstream chip that targets 8800GTX in 3DMark06.
Performance
is estimated at above 9500 3DMarks (2006, not 2005), depending on name of
the partner that Nvidia is talking too.
The name of the G92_290 chip will be the GeForce 8700 GT/GTS, while RV670
should come to market as Radeon HD 2700GT/XT. Fastest G92 board is being
developed under codename P393A01, and it will retail for 249 (we expect
overclocked versions to be priced at 279 and 289 USD), and cheapest variants
will go for 199-229 USD. In short, G92 is simply half a G80, 65nm manufactured
chip sitting on a regular 33x33mm BGA packaging, with a lot of things happening
under the hood. This is not just your cut-down G80 chip, but rather a
combination of higher-clocked part (over 800 MHz), and higher fill-rate than
8800GTS, even though the number of shader units is lower. Nvidia did not cut the
number of ROP units, so expect hellish pixel and Texel fill-rate. RV670 took the
same receipt as G92 compared to G80: cut the number of R600 units in half and
you get RV670. 160 Superscalar shaders consisted out of 32 fatties and 128
regular scalars, blazing high GPU clock... like we said, RV670/G92 are siblings.
