AMD 9950x

[lupaz]

I recently bought my 9950x.

After some tests (testing with 4 of my scenes), the improvement over the 7950x is 16-18%.
(Scene 1: 16.63% improvement
Scene 2: 17.71% improvement
Scene 3: 22.32% improvement
Scene 4: 16.44% improvement)

BUT, I didn't have the 7950x overclocked because the temps were already high at stock.
AMD claims the 9950x is more efficient so I enabled PBO, which led to a higher difference.

Hope this helps.

A little off-topic but I see this processor is not that far away in bencharks than my own threadripper 3970x that I bought for 3-4x the price (some years ago). Is the consumer line of AMDs now that capable?

Pretty much yes I'd say. The Zen 2 Threadrippers are now like 5 years old and we had 3 succeeding Zen generations in between. The "problem" however is that the top end also got a lot faster which means sure, the 9950x is as fast / faster as the 3970x but then the top end chip is still like 2.75x faster than the 9950x :)

They come with issues though, right? I mean, threadrippers. At least with corona. That's my impression after several years of reading here on the forum that those using them were not able to get the full performance. So I was always hesitant to spend that kind of money on more problems.
Is that true do you think?

I've been working on 2 3970x machines (identical) for 3-4 years now and I've had zero issues. The only thing is after long rendering sessions the frequency may drop to ~3.45GHz (less than the advertised 3.7) but that may be to cooling (using Noctuas NH-U14S single fan). Otherwise pretty stable system!

Thanks.
I'll need to consider them the next time
