bit-tech News: Nvidia's David Kirk on CUDA, CPUs and GPUs

[news 28]

Hi all,

 

We have just published an interview with *David Kirk, Nvidia's Chief

Scientist*. During the interview we discuss the changing roles of CPUs

and GPUs, GPU Computing, Larrabee and what he thinks about Intel's and

AMD's futures. If you could post a link on your site that would be very

much appreciated.

*/What would happen if multi-core processors increase core counts

further though, does David believe that this will give consumers enough

power to deliver what most of them need and, as a result of that, would

it erode away at Nvidia's consumer installed base?

 

"No, that's ridiculous -- it would be at least a thousand times too slow

[for graphics]," he said. "Adding four more cores, for example, is not

going anywhere near close to what is required."

 

But what about Larrabee -- do you think Intel will get close to Nvidia

with that? "There are no numbers [for Larrabee] yet -- there's only

slideware. The way that slideware works is that everything is perfect."

 

What if Nvidia has underestimated Intel though and they build an

efficient microarchitecture that scales really well in graphics? "I'm

not going to get into all of the details especially for Larrabee, but

they're missing some pretty important pieces about how a GPU works.

Without being too negative, we see Larrabee as the GPU that a CPU

designer would build, not the GPU you'd build if you were a GPU designer."/

*Cheers guys!
