It looks like that the new RTX are about 50-60% ish stronger than 1080. Unlike games these results won't change much with drivers, so I think that we might expect such improvements.

And if someone will make the calculations to work with the RX cores we could get even better results.

I think will see it in the long iterations. The short ones will be the same, but when the calculations will be on the GPU the bottleneck will be between the iterations.

A ~30% improvement in the overall performance of general-purpose calculations is what we've seen in every new generation of NVIDIA cards the last couple of years.

But as Shintaro also mentioned RELION currently has both an IO and CPU bottleneck and unless you also get a powerful CPU and better disk access, you're not very likely to see those ~30%.

Best,

My take-home message from a recent NVIDEA presentation in our lab was that number of floating-point processors within the GPUs is shifting towards 16bit FPUs at the cost of reducing (or maintaining) the number of 64bit FPUs . As a general trend, this means a shift towards faster graphic processing rather than towards faster scientific processing. Indeed in the quick search on benchmarks I just did, I only saw ~30% improvement mentioned with respect games that I have never even heard of. Thus keep your scientific processing expectations under control!

My two cents,

Marin

We'll wait and see, it'll largely depend on your CPU's ability to keep your GPUs fed with data.
I suspect the typical workstation will not see much speed gain unless you have a very powerful CPU.

I suspect the 1080Ti will still be the better buy for its larger memory capacity.

Hi Douglas,

I don't think they aren't out for the public yet. I think the "founder" edition will be out at the 21.9 and I think the relion users will wait for the "blower" edition so our workstations won't die of overheating.

Subject: [ccpem] RTX 2080 Benchmarks?

Hi

Has anyone had the opportunity to benchmark Relion on Nvidia's newest card the RTX 2080 verses GTX 1080? Non-Relion benchmarks seem to show 20-30% performance increase vs 1080.

Thanks,
