CPU Benchmark Performance: Simulation And Rendering

Simulation and Science have a lot of overlap in the benchmarking world, however for this distinction we’re separating into two segments mostly based on the utility of the resulting data. The benchmarks that fall under Science have a distinct use for the data they output – in our Simulation section, these act more like synthetics but at some level are still trying to simulate a given environment.

We are using DDR5 memory at the following settings:

  • DDR5-4800(B) CL40


(3-2a) Dwarf Fortress 0.44.12 World Gen 65x65, 250 Yr

(3-2b) Dwarf Fortress 0.44.12 World Gen 129x129, 550 Yr

(3-2c) Dwarf Fortress 0.44.12 World Gen 257x257, 550 Yr

(3-3) Dolphin 5.0 Render Test

(3-4a) Factorio v1.1.26 Test, 10K Trains

(3-4b) Factorio v1.1.26 Test, 10K Belts

(3-4c) Factorio v1.1.26 Test, 20K Hybrid

When it comes to simulation, the higher core clock speeds of the Core i9-12900KS didn't make any effect in our Factorio benchmark, which AMD's Ryzen 7 5800X3D with 3D V-Cache gives a more effective boost to performance. In our Dolphin test, the Core i9-12900KS was quicker by around 7-8%, and in our Dwarf Fortress benchmark, the Core i9-12900KS was better than the K, but not as good as the Ryzen 7 5800X3D.


(4-1) Blender 2.83 Custom Render Test

(4-2) Corona 1.3 Benchmark

(4-4) POV-Ray 3.7.1

(4-5) V-Ray Renderer

(4-6a) CineBench R20 Single Thread

(4-6b) CineBench R20 Multi-Thread

(4-7a) CineBench R23 Single Thread

(4-7b) CineBench R23 Multi-Thread

Focusing on rendering performance, the results between the Core i9-12900KS and Core i9-12900K are consistently close. In single-threaded benchmarks such as CineBench R23, we saw impressive performance in comparison to other chips on test, with a 7% jump in R23 single thread performance over the Core i9-12900K.

The multi-threaded performance though between the two Intel 12th Gen Core i9 chips wasn't much difference, but there's a clear advantage in single-thread performance when rendering. It's worth pointing out that rendering is typically a multi-threaded workload.

    Honestly, iGPU performance seems abnormal.. What's going on

    What's the avg power or task energy while doing different workloads? eg. Browser/office apps, video playback, video encoding/Transcoding, MT technical.

    AT is really on top of reviewing the fastest CPUs within less than 4-5 months of their releases...!!! :/

    Doing CPU comparisons with only a 2080Ti is bogus.....(good on ya'll for not using a GTX1060, however!)

    it's fine, just use 720p instead of 1080p, you'll get higher FPS with a 2080 Ti at 720p than a 3090 Ti at 1080p

    In this gen I am very impressed with the i5 12400f.
