Thanks guys, some interesting stuff above.
I’m really just looking for a direct comparison between the 5975wx and the 3990x when it comes to long rendering times in corona.
If i take the middle of the pack for corona benchmark results and compare them, I come to conclusion that the 3990x is about 1.5 times faster than the 5975wx
BUT if i look at these cinebench multicore results here it tells me that the 3990x is only about 1.2 times faster
https://www.cpu-monkey.com/en/cpu_benchmark-cinebench_r23_multi_core-16For both I just divided 3990x score by 5975wx score. Cinibench does not give results in seconds and it's obviously not corona render engine, but surely the same logic applies as it's a multithreaded render benchmark? maybe I'm wrong here?
Bottom line - If the 3990x is only 1.2 x faster then i'll probably turn a blind eye since its quite a bit of hassle to source all the parts for a 3990x build, not to mention the volatility of the price.
But if it’s 1.5 faster then i'll go out of my way to do it, since i'll be getting more than one build for the office. Oh and 5995wx are completely out of the question, £7000+ for a build when they appear to be only marginally better than a 3990x…according to the benchmark results.
Just waiting for that magic person who owns both to give me a comparison benchmark :)
