Media Rendering and Encoding

Blender 2.79b

Moving from the 1920X to the new 2920X in Blender, we see around a 7% decrease in render times. Additionally, the 2920X is almost 20% faster than the more expensive Intel Core i9-7900X.

Interestingly, while Dynamic Local mode provides no advantage to the 2970WX in the BMW workload, we see a 4% advantage in the Gooseberry workload.

POV-Ray 3.7.0

POV-Ray running in all core mode continues to show the advantages that AMD's higher core count can offer in rendering workloads. The 2970WX provides a 27% advantage over the $700 more expensive i9-7980XE. However, in this test, we see a slight performance disadvantage from enabling of Dynamic Local mode.


Handbrake encoding is tested with a 4K 100mbps source file, and is transcoded to 1080p with a constant quality of 10mbps in a single pass encode. The encoders used are the X264 and X265 encoders bundled with Handbrake.

In H264 encoding with Handbrake, the 2920X puts up a good showing, only 5% behind the 18-core Intel Core i9-7980XE.

However, when switching to H265, the AMD processors see a massive performance hit. Even the 8-core i9-9900K manages to outperform the 24-core 2970WX by 15%

X264 Benchmark 5.0.1

Similarly, in X264 benchmark, we see a tradeoff between the Intel Skylake-X CPUs despite their core count deficit, and the Threadripper processors. The i9-7980XE is 9% faster in pass 1, but 10% slower in Pass 2 when compared to the Threadripper 2970WX.

V-Ray Benchmark

A new test for us at PC Perspective, the V-Ray Benchmark evaluates rendering capability for a given CPU with the V-Ray engine, which is a popular add-on renderer available for many 3D design programs like 3DS Max, Maya, and Revit.

V-Ray takes advantage of all the cores afforded to it, as shown by a 13% advantage for the 2920X over the i9-7900X, and a 10% advantage for the 2970WX over the i9-7980XE.
