single-threaded performance, constrain the
load to a single CPU core. The results are so
close that no one would or should care. We
expected the Core i9-10900K to have a little
more of an edge, but maybe it’s the luck of
the draw.
Corona is an unbiased photo-realistic
3D renderer, which means it takes no
shortcuts in how it renders a scene. It loves
cores and threads, so the results here follow
the trend, but the Core i9 finishes just 7
percent shy of the Ryzen 9. In Cinebench
R20, the Ryzen 9 had a larger 15-percent
advantage.
The Chaos Group’s V-Ray Next is like
Cinema4D’s engine, and it’s a biasedrenderer—it takes shortcuts to finish projects
so you can, you know, win an Academy
Award like the V-Ray has (go.pcworld.com/
vosc). It loves thread count, so guess what:
The Ryzen 9 comes out about 14 percent
faster than the Core i9.
Our last rendering test measures ray-
tracing performance using the latest version
of POV Ray. The Ryzen comes in almost 17
percent faster than the Core i9. That’s pretty
close to the thread-count advantage the
Ryzen 9 has, which equals 20 percent more.
Switching POV Ray to single-threaded
performance, the Ryzen 9 squeezes by the
Core i9, which surprised us—we thought the
Core i9 would take the lead.The Corona renderer closes the gap between the
Ryzen 9 and Core i9 to about 7 percent.Core i9-10980XE Caascade Lake-X
