Im quite happy with the numbers considering my monitor maxes out at 1280x1024. :D

The real test is whether 1680 x 1050, 1920 x 1200, and 2560 x 1600 shows it scaling well or falling hard because at 1280 x 1024, a 8800GTS320 can blow through almost everything without breaking a sweat

seriously, i want to see some 1920x1200 benches. i do understand that the majority of gamers out there are still on 1280x1024 but we all know that just about anything after a GTS320 can handle that res.

ps. the TMU ought to be 28 so there are yet some bugs on software:yepp:

joe.latino, in everest with G80/84/86 the pixel pipe = rop's
:noticed these link's
8600GT-everest
8800GTS-everest
8800GTX-everest

so.. only 16 rop's
:(

The very reason I bought the 320... :yepp: :D

Does it look quite strange that there is only a little over 1FPS difference between that higher clock 8800GTS 640 compared to the lower clocked 320mb?

That the 640 had to be OCed to keep up with the 320... yep... I saw... :rofl:

This is strange! i think this is fault, in this resolution they must have the same clocks to perform similar

If those numbers are true then I think a 8800GT will be my next GPU.... :slobber:

What could be the reason why the 640mb needs a much higher clock to perform at par with the 320mb in these results?

maybe they are both 640/320 overclocked and they forget to change the spects in 320!:D

Remember the "8800GTS is equal now" thread?

GT will have 28TMUs, if Nvidia keeps the same underlying architecture.

Texture address units = TMUs.

umm isnt TMU texture mapping unit??

http://en.wikipedia.org/wiki/Texture_mapping_unit

anyway as for how well the GT performs .. i am really eager to see that, as if GT beats GTS, how much will the GTS, and GTX cost?? seems like GT will be ~ $250 MSRP.. also seems like it will have 112 shaders

with 256bit interface, and lower ROP/TMU count it will be limited tho ... vs GTX's 24ROP 32TMU, and GTS's 20ROP and 24TMU, but in shader intense games it can perform near Ultra with 112 shaders @ 1500MHz vs ultra's 128SP @ 1500MHz

still waiting for that D8E tho, that G92 GX2 style card.

$250 would be awesome--can't wait to see the first rebates dropping it below $220. I'll save up a bit for one if that becomes the case.

man I was so close to buying the 2900pro. :eek: glad I waited

thanks everyone for all the links :up:

what wattage do u think the 8800gt will run at and what power supply will it need?

how many amps for the 12v rail?
10-20-2007, 06:47 PM

Power wise I would guess between 8800GTS and 8800GTX range.
10-20-2007, 07:03 PM
tbone8ty

would a 12vrail of 18amps be to low?
10-20-2007, 07:04 PM
RPGWiZaRD

Pretty much same as current 8800GTS which has TDP 108W while GTX is 145W TDP and 8800GT is rumored to be around 110W. Remember the die shrink helps quite a bit despite clocks are increased so expect it to be around 8800GTS levels.

wait, whats the difference between pci express 2.0 and 1.0? bandwidth, power, or both?

About 110-120w.

Less than the GTS.

GTS is ~140w
GTX is ~160w

You're wrong. Texture filter units = TMUs.

Texture Mapping Units (TMU) or Texture Filtering (TF) units.

2900XT has 16 TMUs OK ?

Quote:

Although there is a noticeable trend for games to use more and more shader-based visual effects, practice suggests that complex texturing is still employed widely and the 16 TMUs of the Radeon X1950 XTX often prove to be its bottleneck. It seems so odd then to see the Radeon HD 2900 still have 16 texture filter units.

Quote:

Regrettably, ATI’s new top-end solution Radeon HD 2900 has only 16 texture filter units, which look like a potential bottleneck. The Radeon HD 2600 has only 8 texture filter units: more than in the Radeon X1600, but just as many as in the Radeon X1650 XT.

For comparison, the Nvidia G80’s texture processors contain a total of 64 texture filter units – a fourfold advantage!

Texture Fill Rate = TMUs x Core Clock Do you agree with me ?

8800GTX : 36.8GT/s : 575MHz = 64 TMUs.
