8800GS any good?

[GooGoo]

Does anyone know if the 8800GS is any good and which cards it is comparable with?

 

[marvelous211]

3850

 

[cleeve]

Yep, about as good as a 256mb 3850.

Right on par with the upcoming 9600 GT.

 

[homerdog]

Will we ever get reviews?

 

[cleeve]

Of an 8800 GS? Probably not.

It's not something Nvidia is pushing. It was a stopgap to hold the line against the 3850 until the 9600 shows up, and probably to get rid of old G80 stock to make room for G92s.

There are a couple benches out there though, if you google it.

Isn't the 8800GS a G92 chip?

 

[homerdog]

Isn't the 8800GS a G92 chip?

That's what I thought

 

[cleeve]

Could be. Frankly I assumed they were G80's they were trying to dump. If they're G92s, Nvidia must have really wanted a stopgap card pretty bad.

Funny that they haven't pimped them more.

This is the only one I ever came across:

8800gs is based on g92. 1/4 of everything pulled out of 8800gts 512meg.

12 rop 48tmu 96SP 192bit memory controller.

9600gt is based on g92. Everything a 8800gts is but 64SP taken out.

16 rop 64 tmu 64SP 256bit memory controller.

 

[marvelous211]

8800gs is actually weaker than 9600gt for the obvious reasons like 4 less ROP, 16 less tmu, and 192bit memory controller but 8800gs does shines in shader intensive games at lower resolutions.

 

[Oh SoS]

What's the different between g80 & g92?

 

[marvelous211]

What's the different between g80 & g92?

Different rop and tmu counts and clock speed. Bigger memory bus.

G80 GTS = 20 ROP 24 TMU 96SP 320bit memory controller
G80 GTX = 24 ROP 32 TMU 128SP 384bit memory controller

G92 GTS = 16 ROP 64 TMU 128SP 256bit memory controller

More games are starting to use more shader effects which the G92 GTS has an advantage over the G80GTS and is actually a bit faster than 8800gtx in lower resolutions far as raw performance goes. While G80 has less fillrate but bigger ROP count and memory controller for superior AA performance. G80 GTX is still tiny bit faster if you want to game high resolutions with AA.

 

[aznstriker92]

I don't get how the 9600 is about the same as the 8800GS when it has only 2/3 of the shaders that the 8800GS has.
Even though it has more ROP, TMU. Still.

 

[marvelous211]

9600gt is actually faster. Shader isn't the only thing that dictates performance. More rops would let you run higher resolutions along with bigger memory bus which has effect on AA performance as well. As for TMU. I think it's irrelevant or very little difference especially with G92 cards are already peaking over 20-30 Gtexels/s.

Also these Nvidia dx10 cards do AA the old way. Through pipes. Unlike AMD 2000 and 3000 series which does it through shaders. So more TMU and ROPS you have you get better AA performance.

 

[aznstriker92]

I see.

8800GS = 192 bit memory bus

 

[pauldh]

[H] painted the 8800GS to be an inventory dump with 320MB, 640MB, and 512MB versions appearring, which would lead us to believe G80 or G92. http://enthusiast.hardocp.com/article.html?art=MTQ0MCwxLCxoZW50aHVzaWFzdA==

But we have seen pics of the G92 based 384MB version and have heard about a 768MB version, totally not mentioned by [H]. So maybe they are totally off track with that roadmap , or maybe there will still be all sorts of 8800GS versions.

 

[marvelous211]

memory bus is not the holy grail of performance. IF that was true 2900xt would be faster than 8800 ultra.

I think the crippled bus will do.

The crippled G80 chips became the various GTS variants (320/640) if i recall. Given that the 8800 GT cards are basically defective 8800 GTS (512) chips, i'm surprised Nvidia has so many G92 chips that aren't even fit for becoming a GT.
It would be really interesting to see how good or bad the G92 yields. To bad there is no way of "unlocking" the 192 bit bus o the GS or the missing Shaders of the GT.

 

[Slobogob]

8800gs is based on g92. 1/4 of everything pulled out of 8800gts 512meg.

12 rop 48tmu 96SP 192bit memory controller.

9600gt is based on g92. Everything a 8800gts is but 64SP taken out.

16 rop 64 tmu 64SP 256bit memory controller.

I think you misworded it or confused something. The 8800GS is, as you said, a defective or cut down G92 chip with a smaller bus. The 9600 is NOT a G92.
The 8800GS is a stop-gap solution while the 9600GT is aimed to replace the 8600 series. Since it is aimed at the mid-range, Nvidia developed a new chip that is cheaper to produce than a G92. It is known that the 8800Gs is available in limited numbers only and it wouldn't make sense for Nvidia to cut down the majority of their G92 chips just to supply the demand of mid-range cards.

9600 is a g92 with 1/2 of SP shaved off.

 

[aznstriker92]

Im pretty sure the 9600GT is the G94.

 

[marvelous211]

Nvidia giving a new name? So a g94 is a g92 chip with 64SP.

 

[aznstriker92]

something like that.
