Nvidia's new "Kepler" chip

[lycium]

The reviews are finally out! My favourite site for hardware reviews is Tech Report, and they've got a great review of it here: http://techreport.com/articles.x/22653

Particularly interesting was the LuxRender benchmark, which showed it to be quite a lot slower than the older GeForce GTX 580: http://techreport.com/articles.x/22653/7

This makes me wonder how it'll perform with Indigo's GPU acceleration, in CUDA and OpenCL modes. Some benchmarks for this would be great if anyone has a shiny new Kepler card lying around!

I might buy me one of those when I get my new desktop sometime this summer. Remind me then

I'm soooooo sad about that depressing OpenCL performance
But the flip side is that nobody seemed to to a single CUDA Benchmark at the moment...

People are telling that Kepler was build with gaming performance in mind, so they left GPGPU behind...

I tell you that NVIDA finally discovered that their top price Tesla cards with superior GPGPU performance and higher RAM amount don't sell that good.
A nice business elite doing Science based computing and raytracing just grabs some "cheap" high end gaming GPUs and crunch numbers with them.

So I bet that NVIDA simply aims to shift GPGPU performance totally to the Tesla cards and have a legitimization for such a expensive card with a wide customer range.

Hmm, I'm not 100% sure about that as it only seems to affect certain (complex) workloads; they apparently moved a lot of logic from silicon to the compilation stage, which sounds almost like trying to score a nice free lunch (at least relative to how they had it before!).

The other thing to bear in mind is that unlike all the GPUs since G80/GeForce 8800, they didn't release the Big Mama chip first. Lessons learnt from the Fermi launch, no doubt

I'm still interested in some CUDA based benchmarks...

It seems that the GK110 launching in August will be that Big Mama you talk about

LOL my GTX570 got a score of 384 on that Luxmark 2.0 Room test - much higher than this...

Heh, then there's no use in changing it.

Quite interested with this new Nvidia chip that is to come out. I am not sure what is going to be offered with it though but looking at the benchmark and how they are offered, I would likely assume that they are going to be offered at a far better options. But that is not to out spec what is the other premium offers being pitted out of the new batch.

My guess is Kepler is more graphics-oriented (power efficient in that scenario) by having relatively more cores and less memory (registers and cache) on the chip:
