so that's what it would look like if Intel made a GPU Smiley

F'n sexy!
Yeah I love the industrial metal look without all the plastic.

Helps heat dissipation too  Wink This is not crappy AMD card with plastic cover  Cheesy

You do realize thats an air channel, right?

Hot air channel will heat up top metal cover by convection ( hot air rises ) and conduction and the metal will get hot up there.

Even the plastic on my AMD cards is quite hot to the touch and not normal room temp. even if it does not conduct heat as well as metal

Ur an idiot.

What an insightful post. Buy one of these and show me that the metal case is not hotter than room temperature then call me an idiot.

Until then you are a fool ... metal will surely be hot and help with heat dissipation.

So.. you can remove heat from metal to air... but you can't impose heat by air to metal.. hmm yes, makes sense!

Not totally, a metal shroud would conduct more heat, resulting in different thermal dynamics. But I don't know how much of an actual temperature difference there would be.

Technically you'd want a material that conducts zero heat so it is properly vented out of the case and not leaked into it. Plastic isn't entirely appropriate, but its cheap. Metal isn't appropriate.

gotchya.  didn't think of that.  Used to counting 'spaces' for card :p

Correct, but the solutions these will be used for have large amounts of air flowing over the cards.  IE server racks.  So while this neglects to be used in a regular computer, a server rack filled with these will do just fine.

Yep, that's why I said different thermal dynamics, not better thermal dyanmics. But in the case of a server where these will be used in, it is likely that the case fans will take care of excess dissipated heat with no problems. It also appears to have a plastic coating on the metal shell, unless that is just paint.

EDIT: cmg5461 beat me to it.

I wonder if anyone realizes that people with functioning brains design these products with their features, ON PURPOSE.

Shocking, I know... But true. Tongue

No way, the metal casing was just a design feature to make it look expensive. Plastic looks cheap Tongue

Single Pcie slot. 2 expansion slots. So it depends on which slot you're talking about.

So word on the street is the Xeon Phi is supposed to be directed to compete with the nVidia Tesla presence in the supercomputer market? Seems like a bit of a war will roll out: x86 vs CUDA vs OpenCl? Did AMD stop developing Firestream cards?

I'm pretty sure each x86 core is significantly more capable than any of nVidia's CUDA cores. But because of this, they are larger and there are fewer of them. It depends on how complex your stuff is whether you use this or whether you use CUDA.

This 50core card is designed to do double precision calculations, consumer GPUs only do single precision.

High-end AMD consumer GPUs (69xx, 77xx, 78xx, 79xx) do support double precision.
Most Nvidia ones support it too (albeit artificially throttled).

Yeah, that's why their Tesla stuff shows up in pretty much all of the new supercomputer builds these days, right?  Roll Eyes
