Q1 = Tesla = CES (7 ~ 10 Jan)
CES= CONSUMER electronic show, what use is telsa there?Quote:

I just brought up driver optimizations because LeadHead keeps mentioning the old 295.Quote:

That would put Nvidia in a bad position and I don't want to see that. I would prefer if both companies stayed relatively healthy.
I don't think it's safe to say that we can expect a doubling of performance. I'd suggest that double the performance of a singe GTX285 is the top of the probable range, not the bottom. As per Amdahl, 40% faster then evergreen, etc.Quote:
We still do not know of how the architectural changes will affect geforce performance but its safe to say at minimum a doubling of performance of a single gt200.
Even if the final geforce shaders are 448 total thats still an over doubling of the 275/295 while having all the extra memory bandwidth. I would say its within reason to expect more performance than the 295 without the worry of sli profile optimizations.
After GeForce Fermi gets out, ppl might want to upgrade their older 285GTX.
This way we might find used 285GTX in extremely low prices.
So in case fermi has lower performance than two 285GTX in SLI, ppl might not upgrade.
Actually this was Nvidia's policy by now.
Each new generation to have a bit better performance than the previous in SLI.
In case Fermi can't reach that goal we might consider it a failure.
GTX280 wasn't better than a 9800GX2 in all applications at launch, i had both back then. It became better only afterwards (drivers, etc). This doesn't mean Fermi will be better or worse than 2x240PS GT200's anyway, just stating a fact.
I compare 285GTX with 8800GTX actually. I see nothing in between worth mentioning as a new generation.
I expect the top GeForce Fermi model (single GPU) to have the performance of 2x285GTX in SLI to consider it a winner. Anything worse is bad for Nvidia.
It will be great if that happens but to think that it has to beat an SLI setup to be successful is a bit silly. The vast majority of gamers/enthusiasts are not interested in multi-GPU setups for all the usual reasons. The HD 5870 is only 40-50% faster than last generation parts but that's not stopping people from buying them.
Indeed. HD5870 is unable to beat last generation's Crossfire, or even the downclocked version of it (4870x2).
GTX 295 is 10% faster than HD5870 anyway. If Fermi can meaningfully beat GTX 295, it'll mean that there'll be a healthy difference between Fermi and HD5870 (more than the difference between HD5870 and HD5850) and that makes it good. Of course, what'll make it a success or a failure is the price point.
Did u all read the nvidia's facebook??
Heres what i found interesting:
NVIDIA
Oakridge did not cancel the project. The story was false. Check out www.legitreviews.com. They have the scoop there.

NVIDIA
GF100 is shipping in Q1 folks. Patience is a virtue!

I don't think it will matter. There are some people that will only buy Nvidia and will only look at a fermi as an upgrade to their 295. But most people won't care how it performs relative to the last generation, they will care how it performs compared to the current gen lineup from both companies. Either way they will have to compete on price/performance, naturally. But if performance isn't significantly faster then 5890/5990 then that means worse margins and more market erosion - not what NV needs right now.Quote:

Well ok, but it's not really downclocked in the sense that the 295 or 5970 is. The 4890 was a refresh.
CPU bound.Quote:

People are making comparisons to GTX 285 SLI, hence 4890 is the corresponding comparison on the AMD side.Quote:

Fermi will probably be competing with 5x90 and that could be just a higher binning or an actual refresh. To keep margins high with an expensive chip and expensive board they will want to have a significant performance lead. Otherwise this could be the generation that brings ATI and Nvidia market share into parity. I hope they can pull off 40% faster then 5870, but I'm keeping my expectations low.
Right. But it doesn't really matter because Fermi won't be fighting GTX285 SLI or 4890CF.Quote:

Yep, its competition will be slower than that.Quote:
