The G92 Architecture Rumours & Speculation Thread

Not open for further replies.
*sigh :p

I(we) need further info on the G92(??) high end part.. All I'm reading is the theoretical 1TFlop..
We don't have any release info (19N speculations), no specs revealed, not even the official codename nothing...

My 8800GTX is feeling a bit "outdated" in terms of performance in some recent games..The last 2 months I found myself O/Cing it, in order to get good performance in a couple of games, with the settings I want.. (not trying to be an arsehat here just stating my pov).And I think it's obvious that with the upcoming gaming lineup (with Crysis being the main name) we could use some more power..
Cmon nVIDIA give us something .. :smile:

How about some speculation:


GTX replacement:
24 ROPs
32 TMUs
192 SPs clocked @ 1870 MHz (would be hilarious/awesome if Nvidia does this... 1800 more likely though)
Core clocked @ 750 MHz (maybe as low as 730)


GTS replacement:
20 ROPs
24 TMUs
128 SPs clocked @ 1800 Mhz (another opportunity to use 1870... must... capitalize...)
Core clocked @ 720 MHz (maybe as low as 690)


Rabbit in a Hat (I can dream can't I?):
24 ROPs
32 TMUs
256 SPs clocked @ 2100 MHz
Core clocked @ 805 MHz

Hmm, I somehow fail to see why the 8800GT should be faster than the 8800GTX in anything, if it's really pretty much a die-shrunk chip.

Faster core speeds(Ultra), Faster shader speed(Ultra) and faster mem. speeds(faster than 320Mb anyways = GTX speeds) seems to show that the GT might be finely optimised with it's 256Bit bus. Either that or the 384Bit Bus of the GTX, GTS was not optimally optimised and is wasteful.

All in all, I think the GT is awesome, especially the price.

So right now G92 lack of hardware support of DX10.1 ?

Do you think its possible that they disable it in driver and may enable it in future ?
Its same thing that happaned to IntelliSample 4.0 in GeForce 6 series ?
 
Hmm, that die size about 50% over the RV670 one?

And the cooler's fan size seems to be the old/initial design.

Clock speed alone means nothing if it has less shader/tmu/rop units (which is why I listed the "raw power" number in percentage of a GTS/GTX).
Though those early benchmarks seem to confirm it now, it does not seem to be faster than the GTX in any real-world scenario, sits right between the GTS and GTX which is what you'd expect given the raw numbers.

True enough. I wonder though, everyone complained there was no true mainstream card with a tremendous gap between a 8600gts and 8800gts. Now, the gap has closed price-wise, but actually gets larger performance-wise, their surely must be some room for a card between those (e.g. the initially rumoured 64SP part?)
 
Looking at those numbers, there isnt a much large gap between the 8800GT and the 2900XT. Now 3870 with a slightly higher clock might narrow the gap even further. The only big differentiator I see is the die size advantage for AMD which is close to 50%. :oops:

They werent too shabby with an over-size, (really) under-performing R600. In that sense the RV670 looks like a real winner for them. Good for AMD.

I'm starting to believe that the HD 3870 (god, what an awful name... :S) isn't the real competitor to the 8800 GT 512MB. Even the dual slot cooler doesn't add up.
The report that the manufacturers are already at work on non-reference PCB's for the 8800 GT is a further hint, seeing as the "true" high-end products are usually "shielded" by Nvidia from such practices.


So, i think a 128 scalar processor-sporting G92 with a dual slot cooler (higher clocks and, perhaps, a 320/384bit bus) may be unveiled down the road.
