Have you submitted a Benchmark yet?
I'm thinking of buying the same CPU soon.
It is on sale for the next 2 days for $600 CAN at newegg.ca

I'd like to see how it scales with all 8 cores busy.
I know I'll need FAST RAM.

[QUOTE=petrw1;489169]Have you submitted a Benchmark yet?[/QUOTE]
No. How and where?

I don't know what you mean by "how it scales". Of course I run mprime with all 8 cores busy. That 12ms/it for 332M exponent is the best it can do. The CPU seems really good to me. (cool, overclocking rather well).


BTW, you will need a good cooler.

I only know how to do so on Windows prime95.

Anyone else?

OK, I found the benchmark option in mprime's menu.

I dread to think what a Pi Zero does, it might take days just for mlucas to spit out the first 10k iteration times to test it properly.
