Media Rendering and Encoding
In Cinebench R15, the i9-9900K turns in the single highest single-threaded score we've ever seen. Additionally, the 9900K manages to fall within 4% of the i9-7900X in the multi-thread test, despite its 2-core advantage. That being said, the Threadripper 2950X has a distinct advantage of 34% when all threads are being utilized.
The BMW test of Blender shows a 6% lead for the i9-9900K over the i9-7900X while falling the two CPUs fall within one percent of each other in the Gooseberry workload.
Compared to the i7-8700K, the i9-9900K shows about a 30% performance lead in Blender, tracking almost precisely with its 33% core count advantage.
The POV-Ray All-CPU test shows a 4% performance advantage to the i9-7900X over the new i9-9900K.
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.
While the i9-9900K scores very similarly to the i9-7900X in H264 encoding, the margin between these two CPUs increases to 34% when switching to the more demanding H265 encoding.
X264 Benchmark 5.0.1
The i9-9900K manages to keep up with the Threadripper 2950X in the first pass of the X264 benchmark while losing by 24% in the more multi-threaded second pass.
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's CPU benchmark shows the i9-9900K and the i9-7900X neck-and-neck, while the Threadripper 2950X is around 30% faster.
