Blender Classroom Benchmark
Frequency improvements help to boost the 5900X to a 43 second render time benefit over the Zen 2 3900XT. A render time decrease of 13% when going from the old 12-core to the new 12-core highlights the improvements that AMD is bringing into play with Zen 3.
Versus Intel’s Core i9-10900K, the Ryzen 9 5900X is in a completely different performance league despite costing roughly the same.
V-Ray CPU Benchmark
23% is the lead for the 5900X versus the 3900XT and that is thanks to improved architecture and better all-core Precision Boost clocks. Overclocking the 12-core Zen 3 processor to 4.7GHz again allows it to marginally outperform the 16-core Zen 2 3950X at its stock clocks. Versus the Core i9-10900K, the 5900X is vastly superior.
