Rendering and Encoding Benchmarks
The Corona benchmark also favors the 7700K and 7600K by a slim margin.
We saw the same trend in our Blender test, in which the 7700K and 7600K were clearly faster. I ran this test three times on each CPU after a full system reset and each time the LGA1151 CPUs came out on top.
This can also be seen in HandBrake where the 7700K and 7740X were much the same though the 7600K did pull ahead of the 7640X.
The last application we looked at was Premiere Pro CC and again the mainstream Kaby Lake parts delivered the best results.
