GeForce 9900 GTX & GTS Slated For July Launch

[Nuker_]

Sub 1 Tera flop

Meh..

If the Ultra can get 12 fps on Crysis @ 1920 by 1200, very high, 8 AA & AF on Q9650 @ 4.0ghz

What will the Gtx280 get?

23fps

AFAIK the 933 GF specs come from charlie at theinq, which is a pro-ati biased source.
Besides, the GTX 280 should get about 30 fps at the settings you mentioned.
649$ is what nvidia high end has costed in the past, seems reasonable that 600+ would be just that.

You can't scale flops exactly. ANd 933 Gflops IS the number - its calculated by 3 (2 MADD + 1 MUL) * 1300 Shader Clock * 240 SP = 933 GFlops

But on the other hand, apparently G80 MUL wasn't working 75% of the time so it was closr to 2 * 1500 * 128 = 350ish Gflops rather than the theoretical 581

Also, thats why you cant compare numbers directly over different architectures, even within derivatives (such as G80 Ultra vs. G92 GTX, where clearly the G92 GTX architecture has some memory bottlenecks and performs up to G80 ultra performance at higher resolutions, and even loses some when AA and other things are on at higher res)

So you trust INQ on that matter? And now suddenly after that article everyone seem so sure that the clocks are that low which were claimed by by theinq.

Because very good sources confirmed the clocks... such as CJ.
FYI- That was BEFORE TheInq's article.

If fud is right, we're looking at 600mhz for the core, which seems pretty high considering how large the die is, definitely going to run very hot. That, and that means what the inquirer has said is impossible to happen because 1296mhz just can't happen now for the shaders (unless we're looking at something like a 2.xxxx shader domain lol) and it never could for the core, plus I think its safe to say gt200 won't be spanked by the r700

Yep as LordEC911, CJ had already stated those numbers before Fud ever got a hand on them, and more than a few sources besides TheInq has quoted them.

And that's how the math for counting flops has been done for some time. Lower clocks doesnt mean anything bad - they're just saving us from excessive heat and power draw and the fact that these shaders might have the full 3 operations / sec and you have 240 of them means that you will still get tons more performance from shaders

Have I ever said I question the maths? No... Why do you keep ranting about it then? I undersstand how it works.

Well your saying do I trust those numbers, and those numbers are what were calculated out before Inq ever got his fingers on them, so yes I do actually believe those numbers. What they actually translate to in the real world though, he has no clue

[GoldenTiger]

I'd say 649$

Insane .

[Nuker_]

Insane .

Same price as 8800GTX launched at IIRC, and any other previous high end pieces of hardware.


And with 50% morre efficient shader units, do they mean 50% improvisation in performance per transistor, or 50% higher transistor count, as in more raw power? If the latter was true, wouldn't the maths have to be adjusted for the flop-count, making it well beyond 1 Tflop?

The 50% means the MUL is working constantly now...

And how much performance will able to bring "the missing MUL component" ?

Damn power consumption is just increasing and increasing.

80 ROPs
BTW what do you guys mean the MUL wasnt working 75 percent of the time? Do you mean the third shader can do additional operations now?

Yep essentially the shaders can do all full 3 operations rather than the 2 previously.

Also, it's not 80 ROPs, its 32 ROPS.

Like G80 architecture, its 4 ROPS per 64-bits of memory bus hence 512-bit bus -> 32 ROPS, 448-bit bus -> 28 ROPS

And it looks like the ratio is 24 SP's per 8 TMU's as well which isn't quite the 2 to 1 for G92 but better than the 4 to 1 on G80 (though it was 32TA, 64TF)

whats the story with the 260 shader clock, some sources say 1240 others say 999

Actually I recall $300-400 high-end cards being the norm not so long ago. In this economy especially, $650+ for a card seems WAY out of line where money is tighter.

[SamHughe]

Isn't it kinda weird that there is virtually no reviews with definitive numbers for a graphics card that is scheduled for a July release date?

that's because it's still under NDA

What he means is: If I didnt have to sign/agree an NDA could actually tell you some numbers.....

I'm pretty sure that it is 40TMUs and 80TFUs, ala G80 style.

will we get some benchmarks this week ?

I'm going to Jamaica tomorrow for two weeks with my brothers, so I know I'm going to come back to all kinds of goodies, maybe even a launch!

BTW, I just finished playing Gears of War on hardcore. Excellent game. Noticed your avatar.
