Aggie The Pew has passed us, just like last challenge. They just have the advantage of numbers: there are nine of them active.

I added two EPYCs, back in individual #3 now after major SNAFU this afternoon where I lost all progress on 300 single core Intels and 30 x 12 core Intels. Stupid oversight on my part.

300 single core Intels? Throwing everything in, but the kitchen sink?
I am now within a hairswidth of a ruby badge for Primorial Prime Search (PRS) at PrimeGrid.

And right now we passed Aggie The Pew, and have ryzen to 5th position again. Epyc performance.
And Aggie didn't pull a rabbit out of his hat, like last time, so we stayed #5.

Yay team.

I ended up with 100 x 12 core Intel Xeons with AVX512 and 200 single core Intels plus my home pharm and 6 AWS quad cores (mixture of EPYCs and Intel Platinums). The AWS EPYC 16 cores didn't play nicely with BOINC and PrimeGrid. For unknown reasons 2 ran as if they were dual cores and 4 ran as quads but I was paying for 16 cores per machine. I tried them for 12 hours then trashed the instances and switched to quad cores at AWS EC2.

Single core Intels....I hope that it were 8-cores running eight WUs at a time or so. What was the last single core Intel able to run a decent BOINC?
My best crunchers were a Ryzen 7 5700X and a Ryzen 7 8700G, both running with hyperthreading and doing 16C WUs. They managed to do the non-proof tasks in a little over two minutes, the proof tasks in a little over two hours.
