The G92 Architecture Rumours & Speculation Thread

[Domell]

Are you so sure? What if the 8800gt is the full 96sp and the 8700gt that we have also been hearing about is 64sp part?

Well, i can`t tell you i`m sure about it but on PCInlife and Chiphell forum you can find this info. One guy said GF8800GT is not the strongest version of G92 and that GF8800GT is 64SP it doesn`t mean G92 is 64SP It`s very possible way. He seems to have info from reliable source (like about G80 one year ago)....

GF8800GT 16TMU, 16 ROPs, 64SP -- 200-250$ against Radeon HD2900Gt

GF8xxx 24TMU, 16 ROPs, 96SP -- ~300$ against Radeon HD2950Pro Gladiator

If I was to run with that, I would point out that the 2900GT is said to go EOL before RV670. Their for pitting the 64sp part up with "Revival" instead.

 

[AnarchX]

Yes, Revival (~2950Pro) should be 8800GTs enemy, if the price-rumors are correct (256MB-$199,512MB-$249).

16 fat(8Z, 4xMSAA-SC) ROPs and 16 TMUs with free tri (@600MHz like rumors) should be enough against it, but the arithmetical output(specially MADD) could not be enough, and I doubt such a lower part will hit a shader-clock far above 2GHz.
So NV maybe made something with shaders: @PCinlife they talked about Dual-MADD, what I doubt a bit, another good possibility to get more arithmetical power in a cluster would be imo to add just another Vec8-unit (=8SPs).

With this could a 4 cluster 8800GT reach at conservative 1.8GHz a output of ~460GFLOPs(MADD+MUL), which should be enough against Revials 480GFLOPs, which shaders work with lower efficiency.

My guess for 8800GT: Pix/tex-fillrate and bandwidth below 8800GTS, but arithmetical power higher, to keep up with RV670.

btw.

According to FUDzilla, the G92 launch has been brought forward to October 29th:

Also (supposedly) the version of G92 launching this year will be called 8800GT, with all that this implies in terms of performance:

So a year has passed and we are anxiously awaiting a 10% overclock on R600 and a new card that's slower than the 8800GTS....anybody else as excited as I am?

It looks like Nvidia will have a rough time though. R600 has started to knock on the GTX's door in some titles so I'm not sure that a slower G80 will fare very well against a faster R600.

The batch of cards due out in November are not "high-end", they're mainstream cards. Think of them as being replacements for 2600XT and 8600GTS, with comparable prices, but performance almost on a par with R600 and G80.

The next "high-end" products will be coming in January. Rumour has it that the Nvidia version will be dual-PCB and the ATI version two chips on the same PCB.

After that, we'll see a "true" high-end product from ATI, the R700, in (we hope) Q2/08. I haven't heard anything about a rival Nvidia product, but it seems reasonable to assume there will be one.

3 weeks ahead of rv670 (when AMD not delay rv670), thats a lot in that timeframe.

Some game what coming out 10.29<->11.19 (source is amazon)
Crysis 11.16
Call of Duty 4 11.09
Hellgate London 11.02
Timeshift 11.02
Clever Kids: Pony World (for this noone need any g92 or rv670 for sure )

I believe the lament is that you are right. The mainstream cards should have been Spring/Summer, with a fall refresh on the high-end, rather than a late-winter launch. NV appears ready to blow its lead, while ATI finally launches some competitive hardware.

That said, the interest here is technological, and therefore tilted a little unfairly towards the high-end. No doubt the mainstream cards are more important from a money perspective. It looks like ATI has lined up a real winner, depending on where prices finally fall. If NV has to, I would expect them to be able to drop prices shortly after launch, so, in the end this is likely a real win for the consumer. Heck, maybe even *I*'ll buy a videocard

I thought the mainstream replacement for RV630 was RV635, not RV670.

Or are we getting confused on the differences with mainstream and performance segments?

 

[AnarchX]

RV63xXT will drop from lower performance to mainstream or from another view from highest mainstream to lower mainstream. (like RV53x in the last generation)

8800GT is the cost of the 7900GS and performance of 8800GTS.

 

[[Brick_top]]

8800GT is the cost of the 7900GS and performance of 8800GTS.

Is that something like 199 or less?

 

[vertex_shader]

8800GT is the cost of the 7900GS and performance of 8800GTS.

8800gt won't cost 120$ before next year Q3

Nah, the BOM cost for G92 standard board.

 

[Domell]

Hmm if D8M is GF8800GT what is D8P??

 

[trinibwoy]

Supposedly G92 without any units disabled...

the Second Picture is 8800GT.

for people that don't care much about the high end because of cost and power, there's a reason to be excited. that's awesome midrange which goes well with the awesome parts you get in a midrange PC nowadays (a high X2 or a "low" C2D, 2GB ram, 500GB hdd)

From the estimated specs I have seen for the top 2950Pro (825MHz, 320sp and 2.4GHz GDDR) that is more in competition with 8800GTX and so be the top end, not mid range at all.

Nvidia seems to be simply replacing a very popular midrange card with another cheaper to produce one, so the 8800GT is not in competition at all with the RV670.

I think nvidia will rush out GX2 if 2950Pro takes top spot....

Thats 2950XT and the enemy should be a 8800GTS with 112SPs/28TMUs:
