New thunderbolt box to ad CUDA to Macbook Pros?

[Daniel Frome]

HIghly doubt it. They are pushing their own version of CUDA: OpenCL. That should run on Nvidia or AMD cards alike, but I doubt Nvidia is enthusiastic about it.

From the looks of the box, It can’t handle a real video card. My newly purchased GTX570 take 2 slots, and that box looks like 3 tightly packed slots.

Looks like they are still taking usage input there. If the power requirement is low enough I think I read Magma had ~200w, a one slot card like the NVidia 4000 might work, Thunderbolt is certainly fast enough. They are saying it would support video capture cards.

Yep…most of the lower end CUDA cards are single slot. The thing is, most of those low end cards have full CUDA capability. We just need to make sure that OSX can see them.

I would love this to be the case. Ha…the case! Whatever.

Daniel, who are they?

I don’t really see what you are talking about. Please clarify.

“ExpressCard can only offer 5Gb/s in ver 2.0, which is similar to PCIe2.0 x1 speed.
Thunderbolt has 10Gb/s per channel, and since it’s a dual channel connection, we are talking about 20Gb/s per cable, which is similar to PCIe2.0 x4 speed.

there was a test performed to see how does PCIe link speed affects cards performance :

the test showed up to 20% decrease of frame rate just because of a slower link speed.
and keep in mind that test was performed on a 4870, today’s cards probably uses alot more bandwidth.”
