GTX 1660 or Core i9-10900K
 

Which one would be better for prime numbers hunt? I already have the GTX 1660 video card that I mentioned and I wonder if it's worth building a new rig with the latest and fastest CPU? Or the GPU computing with the hardware that I already have is superior to any new CPU? Thank you.

Welcome. GTX 1660 is excellent at TF, far faster than CPUs for the dollar invested or per kilowatt-hour.
CPUs and AMD GPUs are better at other forms of GIMPS computation typically. Radeon VII are CPU beaters on both price/performance and results/watt-hour. Radeon 6xxx are supposedly pretty good too.
There's also cloud computing, some of which is free, so hard to beat on price/performance.
So, it depends what you want to run, and how much. Try some out and see what you enjoy most or least.

Welcome to the forum,
I have values for the GTX 1650 Super and the GTX 1660 TI for a specific exponent in the [URL="https://drive.google.com/file/d/10fC4lND0DJlv_5-TgCwZGngenkBdAaRP/view"]gpuOwl-Comparison List[/URL], give me a benchmark for the GTX 1660 if you want, to make the sheet more useful.

I'll gladly do that if you'd tell me how :)

Thank you! I'll stick to my current video card then, but will probably invest in something better along the road. I tried cloud computing too and enjoying a free month, not bad, price-wise :)

Download the Windows version

Fastest Windows Version (with Proofs)
[URL="https://mersenneforum.org/showpost.php?p=551594&postcount=8"]https://mersenneforum.org/showpost.php?p=551594&postcount=8[/URL]

Then run the first 300000 itterations with gpuOwl for the exponent 77936867 at the Windows command Line.

Type [B]cmd [/B]in the windows search field and switch to the gpuOwl directory with [B]cd path[/B] f.e. cd C:\Users\username\gpuowl-v6.11-364-g36f4e2a.
Execute the binary at the command line with [B]gpuowl-win -iters 300000 -prp 77936867 [/B]


or you use the Linux binary version (needs further installation effort, read: [URL="https://mersenneforum.org/showthread.php?t=25601"]How to set up for running gpuOwl under Ubuntu (and other Linux) with OpenCL[/URL]

Linux binary version Ubuntu 18.04

[B]gpuowl -iters 300000 -prp 77936867[/B]

post the result from the gpuowl.log file in this thread [URL="https://mersenneforum.org/showthread.php?p=585779#post585779"]https://mersenneforum.org/showthread.php?p=585779#post585779[/URL]

Done, log posted!


You're saying that gpuowl-win v6.11-364-g36f4e2a is faster than the latest gpuowl-v7.2-69-g23c14a1 ?
