not sure it really matters. If you look at response below, my render time increased decreased dramatically with 3950x. I will also mention that it will be one thing to announce new chips, it is another to actually provide them to the market at non inflated prices. It was crazy looking for build parts, trying to find them in stock and thennot overpaying for them. The impact covid has had on production is ridiculous.
Fixed that for you, although I'm sure you had meant to say that your render
speed has increased dramatically with the 3950x.
that is a fair point. To be honest, the cpu is slaying the renderings compared to my 9th generation I7 9850 build. On an Arnold rendering in 3dsmax, the rendering clocked in at 2 hrs 20 min. On my ryzen the way I have it set up, it clicked in at 1 hr 12 min. I am thinking it is not worth messing with.
I'm pretty sure he was kidding with you, since a 1900XT will clock higher, but since it only has 12 cores, it will for sure be slower in rendering than your 3950X. It would require the clock speed to increase by 25%, to make up for it only having 75% as many cores, and there is close to a zero percent chance of that happening...and then it would only match your 3950X in rendering speed. Your next step up the ladder is more cores. If you don't mind paying twice what you paid for your 3950X, you can buy a 24-core 3960X, but those also require different and more expensive motherboards, so it would not at all be cheap, but it would increase your speeds by 50%, as long as you don't mind buying a larger AIO setup, so you can clock 24 cores as high as your 16 cores are going now.
