Nvidia's new "Kepler" chip

Post by lycium » Fri Mar 23, 2012 4:12 am

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! 8)

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

I'm soooooo sad about that depressing OpenCL performance :cry:
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:
