The Intel Core i9-7900X 10-core Skylake-X Processor Review
Media Encoding and Rendering
Audacity MP3 Encode
A very single-threaded workload, the Audacity test shows another big gain for the 7900X over the 6950X, on order of 30%, matching the performance of the Core i7-7700K.
A classic test of multi-threaded capability, the Core i9-7900X sees gains of 15% over the Core i7-6950X and 35% over the Ryzen 7 1800X.
X264 Benchmark 5.0.1
Interestingly, pass 1 shows very little advantage over the Core i7-6950X for the Core i9-7900X (2.7%), though our pass 2 results give the edge to the Skylake-X part by 18%.
Here is another instance of strong single thread performance improvements allowing the Core i9-7900X to match the performance of the Core i7-7700K, the previous single-threaded king. A 25% improvement over the 6950X gets us a score of 197. On the multi-threaded result the 7900X has an advantage 15% over the 6950X and a 34% lead over the Ryzen 7 1800X.
Similar to the CineBench R15 scores above, POV-Ray gives the new 7900X a 22% lead over the 6950X and a 38% lead over AMD’s Ryzen 7 1800X.
We run two different Blender workloads, and both show interesting data for the Core i9-7900X. While in the BMW render we see a 15% advantage for the multi-threaded performance of Skylake-X over the 6950X, that lead is only 6% in the much longer Gooseberry workload, as it spends more time in procedural calls.
