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.

    peak power was 276 watts...

    Peak power can get way higher.

    I'm sure kilowatt PCs will cause no electrical problems at all. At this rate people will need to hire an electrician to make sure it's safe. It's not like DIY repairs in hurricane and flood zones ever cause fires or deaths.

    It's just so violently 'Murican. Pure horsepower and engine size, drinks tons of fuel and is inefficient as hell. The alternatives do way better with less power and cost you less to run. It's just so..brash.

    But people will buy it because they wanna wave their willys.

    Because enthusiasts don't exist.

    All the top CPU designs are American ;p

    Would have loved to see one 12th Gen Core i9 at each power level in the charts — i9-12900T, i9-12900, i9-12900K, and the i9-12900KS — to see how the power/performance looks across the gamut.

    Yes - the 12900T looked the 2nd-most-interesting chip to me in this lineup, I'm curious what this does at lower power.

    I think the 12900F looks best because: it's the cheapest, doesn't have a iGPU you won't use, uses less power but not a particularly bad regression on clocks.
  • Alistair - Sunday, July 31, 2022 - link

    but the 5800x3d is far ahead of the 12900f

    Those heat output could be linked to the LGA 1700 locking issue. i bet those who bought such a chip won't mind using the aftermarket bracket.
