Cinebench R23 3D Rendering Benchmark

The new Core i9-14900K wasn't able to catch the Core i9-13900KS in either the single or multi-threaded tests, but it did beat every other processor in the stack. The Core i7-14700K couldn't quite catch the Ryzen 9 7950X3D, but the Core i5-14600K clearly outpaced the 13600K and nearly caught the previous-gen Ryzen 9 5950X.
POV-Ray CPU Ray Tracing Benchmark
POV-Ray tells essentially the same story as Cinebench, with the Core i9-14900K slotting in just behind the Core i9-13900KS, and the Core i7 and Core i5 finishing in familiar positions relative to the competition.
Blender Rendering Benchmarks
Blender is a free and open source 3D creation suite that can handle everything from modeling, rigging, and animation to simulation, rendering, compositing and motion tracking. It has a purpose-built benchmarking tool that will track the time it takes to complete rendering a particular model (or models). We used the CPU-focused benchmark with all three models currently available...

Surprisingly, the new 14th Gen Core processors finished just behind their 13th Gen counterparts in the Blender benchmark. The deltas separating the processors are very small, but were repeatable nonetheless.
Y-Cruncher Multi-Threaded Pi Calculator

Once again we see a familiar trend, with the Core i9-14900K just missing the mark set by the special edition Core i9-13900KS, with the 14th Gen Core i7 and Core i5 competing favorably with previous-gen parts.
STARS Euler3d Multi-Threaded CFD Benchmark
This benchmark is multi-threaded, but is also dependent on platform bandwidth, and cache and memory latency, so the final results are not determined by compute performance alone. Cache sizes / speed and memory bandwidth affect the score as well...

This benchmark had all of the Core i9 processors tightly packed at the top of the charts, with the Core i7-14700K falling next in line. And once again, we see the Core i5-14600K finishing just a touch behind the Core i5-13600K. This doesn't make much sense considering the 14600K has higher clocks, but it is what it is. The delta is quite small, anyway.
