Fermi in trouble?

We all know it is constantly being delayed - but at the end of all those delays, what we were expecting was a stellar product from Nvidia. However, with today's press release, certain inconvenient details are revealed. Let's forget about the delays for now, and just consider the product itself.

The first Fermi GPU - GF100 - as we know for a while now, is a 3 billion transistor giant, taking a die size of around 500 mm2. Compare this with the 2.15 billion transistor, 330 mm2 Cypress on the same 40nm TSMC process, and you would be expecting a different class of product. Unfortunately, the details revealed today about cast an uncertain shadow over this basic assumption.

The first thing worth noticing is a complete and total absence of Single Precision performance figures or any comparison to direct competition - i.e. ATI's GPGPUs. It is clear that Fermi's real performance advantage would be Double Precision performance - had it hit the right clock speeds.

However, today's press release suggests Nvidia have missed target speeds by a lot. To be fair, Tesla products do clock lower, though not by much. In fact, GTX 280 and Tesla C1060 were clocked the same. Even taking a generous increase for Geforce products, things are still uncertain. As a result, DP performance is rated at between 520 GFlops and 630 GFlops. Suddenly, ATI Radeon HD 5870 - which wasn't even supposed to be a direct competitor - is performing right on par with 544 GFlops against Fermi's supposed strong point.

Consider Single Precision - far more important for gaming graphics, and things turn rather ugly. GF100's target speeds were reported to be...

Well they're trying something completely new, it's not surprising they're running into a ton of problems.

That report seemed highly Biased....

Speculative speculation is speculative.

Very interesting.

This is the scary part.
Possibly paying premium ATI prices for many more months.

And we have not factored in the fact that GF100 is nowhere to be seen, and are unlikely to be on shelves in quantity for at least 4-5 months. Any further delays, and we will be looking at new products from AMD.

very interesting. the Q1 10 is good, but everything else is bad. vr is fairly well known for presenting the news... this cannot be good for nvidia =/

Speculation?

Tesla C2050 & C2070 GPU Computing Processors
- Single GPU PCI-Express Gen-2 cards for workstation configurations
- Up to 3GB and 6GB (respectively) on-board GDDR5 memoryi
- Double precision performance in the range of 520GFlops - 630 GFlops

5870 gets 544 GFLOPS of double precision, can't argue those numbers.

Looks like nVidia right back where they started. They have a massive die, a much more expensive product, and the performance simply isn't there.

Best case scenario it looks like we're going to get another HD 4890 vs GTX 280 battle again, instead of the GTX 285 vs HD 3450 that the nVidia fanboys were predicting.

Can't be good for those who want ATI cards either, due to pricing.

Speculation pertaining to the gaming performance.

Didn't seem biased to me. Just some concerned performance enthusiasts. We all want to see fermi, hopefully sooner rather than later.

Damn, I hope they get this figured out. DX11 and the future of all awesomeness on PC gaming is depending on Fermi coming out and competing with ATi!
