I did end up upgrading to the 3950x after all. It does seem faster than my previous PC, however i dont have any raw comparison between the 2 unfortunately. Its a bit hard to judge when it still takes hours/days to cache a particle sim. xD
So far the 3950x is doing fairly well. I hear its a big step up from even the previous gen threadrippers. Its basically a 3rd gen thread ripper but on a more common socket type.
One really odd thing i noticed with tyflow however. It seemed to simulate MUCH slower after i overclocked my CPU. I get about 3800-3900 in cinebench stock, after my OC it jumped up to 4300, however tyflow seemed to take 1.5x longer so simulate and i have no idea why. It looked like it wasnt utilizing the cpu as well when it was overclocked. The cpu utilization graph in the task manager was very spiky, jumping way up and down, whereas is was mostly stable at 80-90% without the OC.
Could it possibly be due to the single core vs multicore speeds? Without the OC the highest my cpu can boost a single core is 4.7ghz, however if all cores are used it drops to around 4ghz. After the overclock all my cores were running at 4.3ghz, however that stops the single core form clocking higher than that. Are there some single threaded processes that benifit more from raw ghz than more cores? Perhaps some old single threaded legacy code from max itself might be causing this?
Thanks!
