Would you upgrade my CPU?

i think the more cores/threads the better for PI; i've not seen a knee in the performance even at 32 threads... there are a couple of benchmarks in the database with some insanely big machines; you can see how the scaling holds up by comparing those results to more modest machines.

That makes me wonder how the 3600 benchmark's are similar to the 2700x even though it's 4 threads less.
They must've done really great job with the ryzen gen 3.

Might just think about getting the 3900x/waiting for the 3950x so I won't need to upgrade anywhere further in the future.

yea someone posted a PI benchmark over on cloudynights from a 32-thread ryzen 3 and it kicked the pants off my gen 2 chip.

Gen 3 with 32 threads? Isn't it only on 3950x/threadrippers?
The thing is the 3600 has only 12 threads.

well you were right, i went back and looked at it and it was an 8C/16T 3700x. which makes it all the more impressive; my 32T 2950x gave about 11000 on the PI CPU benchmark and his 3700x gave 14000+.

Yeah that's really impressive. I was fairly sure that the more threads the better performance, but now that makes it even more confusing choosing.

One thing I'm thinking though, is that the cpu bench could be a mix of actions such as single core bench's etc, which is not as important for me as the multi thread actions such as integration, debayer and such.

So maybe the 3600 bench is higher for example, but on the long multi thread operations it still might be a bit slower.

No idea if what I'm saying is true though.
