Oak Ridge cans Nvidia based Fermi supercomputer (SemiAccurate News)

What sources are these? I'd love to see them and I hate Charlie!

Sources are sources. Anonymous stays anonymous. Charlie doesn't burn his so why should anyone else in this industry burn theirs? That's the way investigative journalism works.

As I said: I would expect an announcement in the next few weeks for better or worse.


As for which card is "better" for these scenarios, I would expect Fermi-based Tesla cards will trounce anything ATI can produce for HPC specific applications. Fermi was tailor made for HPCs and as such incorporates technologies that certain sectors have been looking for and the competition has no hope of delivering anytime soon.

ECC is not only a perf hit, Nvidia's implementation uses up a considerable amount of space too.

Are you guys seriously talking about power efficiency? The competition is CPUs and the most power inefficient GPU is still far more efficient than the best CPU.

In either case Fermi has no competition. HD 58xx's gaming performance means squat in an environment where Fermi's ECC support and cache hierarchy are a big deal.

Isn't it actually the HD 5800 that has no competition? I don't think you can come to any conclusions until the card gets to the store shelves.

You are talking DX11. This thread is about HPC applications where ATI has little to no ongoing support of any kind.

So what exactly is the TDP of the high end Fermi based GeForce? And what about 3D performance? Because without that information you can not logically make the claims you are trying to assert.

It sounds like you lack some basic logical reasoning abilities. There is plenty of information about how these firms design chips, and the resulting power specs...maybe you are in denial because nVidia has been selling in a box for the last year? I suggest you go read the tech specs of RV800 (can you find those on your own?) and then read about the JumboDie TM design scheme that nVidia thinks is going to work (and is producing record low yields). A basic understanding of chip physics will tell you that 5890 is definitely going to beat whatever nVidia comes out with in terms of performance/watt. With such crappy yields and ATIs headstart (and opportunity to die shrink and cut prices) they are going to be also losing in performance/dollar. At this point the only thing that nVidia could possibly win at is total XOPS, which considering the differing technologies may be better for WCG etc. at performance/card, but that is a relatively useless metric in any market that matters...

I take a nap and Fermi threads start sprouting up like weeds on my lawn.

Take the discussion here please -> http://www.xtremesystems.org/forums/...d.php?t=241120

Regarding the original Fermi thread that was moved to the Nvidia section, I didn't know it existed else i would have moved it back.
