Mike Wright Posted September 12, 2017 Share Posted September 12, 2017 Hi I'm speccing a new machine for VW/C4D/V-Ray rendering. I have the choice between an Intel i9 7900X or an AMD Ryzen TR 1950X The i9 would be overclocked to 4.5Ghz Performance wise the AMD chip seems to benchmark higher on multi-thread applications whereas the i9 would fare better on single thread I've read a few reports of even high end liquid cooling struggling on the i9 when overclocked Anybody got real world experience of either or even knowledgeable advice? It's not really my field just need to make the right choice Quote Link to comment
zoomer Posted September 12, 2017 Share Posted September 12, 2017 I saw in tests that the Threadripper also needs special cooling. a) needs larger cooling plates as currently available for AIO water cooling b) High wattage cooling c) Air Coolers not available but will come d) Even with good cooling, Threadripper gets very warm on the backside of the mainboard. I think both options need a bit of carefulness. Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted September 12, 2017 Vectorworks, Inc Employee Share Posted September 12, 2017 I would say the large majority of rendering (that isn't handle on your GPU) is going to favor multi threaded performance specifically. The i9 seems to beat the TR by a significant margin in that regard in Cinebench, which would give you the most accurate picture of how Renderworks renderings would be affected. Quote Link to comment
Mike Wright Posted September 12, 2017 Author Share Posted September 12, 2017 I'd read the opposite, Cinebench R15 score for the i9 (multi core) is 2194 as opposed to 3000 for the TR which is a huge difference Quote Link to comment

Mike Wright Posted September 12, 2017 Author Share Posted September 12, 2017 Thanks Jim That was kind of the conclusion I had made. I'll post some real world experience on here when I've worked with the machine for a bit Quote Link to comment
Mike Wright Posted October 2, 2017 Author Share Posted October 2, 2017 It's arrived. Cinebench R15 reports a CPU score of 2908 Not too shabby. Quote Link to comment
