NVIDIA today unveiled the NVIDIA Tesla K40 GPU accelerator, the world's highest performance accelerator ever built, delivering extreme performance to a widening range of scientific, engineering, high performance computing (HPC) and enterprise applications.

Providing double the memory and up to 40 percent higher performance than its predecessor, the Tesla K20X GPU accelerator, and 10 times higher performance than today's fastest CPU, the Tesla K40 GPU is the world's first and highest-performance accelerator optimized for big data analytics and large-scale scientific workloads.

So in other words, the K40 is to the K20X as what the GTX 780ti is to the GTX TITAN, hardware-wise?
WOW. Not impressed much :(

Well, there is one thing interesting about this. This card is the first time I've seen 4Gbit GDDR5 chips used. Get ready for another doubling of graphics memory next video card generation.

Not really.
The GTX 780 Ti has half the onboard memory of the GTX Titan
The Tesla K40 has twice as much onboard memory of the K20X
WOW. Not impressed much :(
Based on your erroneous assumption and the fact that you aren't the target demographic for the board I am not in the least surprised.
There is a "contact us" tab at the Eurotech site should you wish to give these supercomputer manufacturers the benefit of your experience.

I know this. I simply decided to handwave this fact out in my comparison. As I was pretty much only taking the GPU itself for that comparison.

Well, the way they presented it, it felt as it was supposed to be something heaps faster than the previous top Tesla product. They said it as if it was so fast, it would be more than enough to revolutionize computing. But meh, it's just marginally better [not counting the 2x memory amount]. Shame on them for getting me too excited for a moment there.

Have you not read press releases before? Even the most minor of improvements is "revolutionary" if it's in a press release. :)

My primary research focus includes a ton of computational electrodynamics work (mainly FDTD in OpenCL) and while the raw crunching power of the GPU is only a moderate upgrade the 12GB of RAM almost justifies the price tag. It's VERY easy to fill up 6GB of RAM, so for sims requiring more RAM you need to get creative with memory management to avoid the large overhead from excess PCIe transfers. 12GB is also pretty easy to fill up, but it gives quite a bit of extra headroom to more creatively manage host-device transfers. Storing the relevant information of a sim across both GPU and system memory can cripple performance by an order of magnitude or more :twitch:

I'd kill for even a mid-range gaming GPU with 16GB+ of RAM...

K40

This is a nice chunk more performance for those special users and to keep the same TDP is impressive. GPGPU is becoming a much more mainstream tech and Nvidia is at the forefront.
