Something that's gonna face every artist building a new rig, which is better a fast cpu or more cores. Well let's find out, I'll focus more on simulation tasks (Pyro,Grain,ocean).

This chart is going to be up to date, so I'll really appreciate it if you ran the tests as well and shared your results, I'll list them asap with your name ;)

You can download the three test files here.


One small favor to ask from you, if you like what you find here and wanna me keep going please do consider supporting me on Patreon, and it wont be for free since you will be rewarded with access to alot of setup and tools I create, and the library is growing larger ;)


Back to the tests and all you have to do is:

  • Open the Hip file.

  • Dial in the resolution numbers as in the chart.

  • Go the performance monitor tab and hit record.

  • Hit go to the last frame.

  • Wait until the simulation is finished and grab the result from the performance monitor.

  • Convert it to seconds please.

  • Done.

  • Note: Opencl is off in the files so leave it as is.

Tested CPUs :

  • Threadripper 7970x, 7980X.

  • i7 6800K .

  • i9 7900x (Dorin Croitoru).

  • i9 7940x .

  • i9 7980xe (Fabian Buckreus).

  • TR 1950x (Siavash).

  • TR 2990wx (Peter Sanitra).

  • 2x (Gold 6136 , e5-2630 , e5-2620 v3) Martijn Grootendorst.

  • 2x (e5 2630 v4 , e5 2699v3) by Dominik.

  • (i7-4771 , TR 1900x) by Muhaylo Shchurba.

  • TR 2950x (Matti Orgelmann).

  • Ryzen 9 3900X (Slava Sych).

  • Ryzen 9 3900X Linux (Martin Brattensborg).

  • TR 3970X / i7-6950x (Jim Huenergardt).

  • TR 3970X Linux (Ryan Leasher).

  • TR 3960X (David Riesenberg).

  • i9 10980XE (Slava Sych).

  • Ryzen 9 3950X (Alexander Karelin).

  • TR 3990X (Nawras Ryhan / Felix Antoine Ludvig Hedberg).

  • Ryzen 9 5950X Linux (Mika Ihatsu).

  • intel i9 13900KS, 14900KS

I'm back now with the Silverstone XE360-TR5 AIO cooler for my 7960X. Not a gigantic gain in time, but an incredible relief in temperature. Not sure of any improvements I can do to the time without overclocking, but I'm open to suggestions.


Threadripper 7960X

256 GB

RTX 4090

Windows 11


Grain 2m53s (173 sec)


Pyro 8m25s (505 sec)


Ocean 19m41s (1181 sec)

Thanks Evgeny!


Final testing results:

Intel 285K

MSI MAG Tomahawk Z890

128GB GSkill DDR5 RAM 6000 CL34 (5600MHZ for stock test)

Integrated GPU

Windows 11

Houdini version 21.0.440


Default CPU Bios settings

Pyro: 6m 26s

Grain: 3m 03s

Flip: 19m 33s


Note, testing with +200S Boost Setting Enabled with XMP made almost no difference from stock


Overclock Result

E-core Overclock to 5.0Ghz @1.22v, P-cores left stock

Ring clock 4.1, D2D and NPU manual clock to 3.2, XMP enabled

Average CPU TDP for this overclock runs about 280W under full pyro load.


Pyro: 6m 01s

Grain: 2m 51s

Flip: 18m 27s


A P-core overclock is definitely possible in conjunction with the E-core OC, but I had stability issues when using adaptive…

Hey Evgeny, just letting you know the 285K OC result for Pyro was entered into the sheet as 3.01 instead of 6.01 :)


Could be worth adding my commentary as a comment into the sheet to help anyone else looking to OC their CPU

Hi there, currently running some benchmarks for a new Intel 285k build, and am getting some warnings:


/obj/pyro_sim/pyrosolver1: Skipping unrecognized parameter "correct_collisions".


/mat/flames: Skipping unrecognized parameter "folder2_4"

(a number of folders through to 25)


/out/mantra_ipr: Skipping unrecognized parameter "output5"


These are the warnings I get on Pyro, Grain has no warning and Flip has the /flames and /mantra_ipr warnings only.


I was originally getting crashes that were preventing me from running Pyro, however after updating some drivers I can now run it, however the warnings remain as above. My Pyro solve time looks better than I expected (6m24s), so just want to make sure that the error isn't actually speeding up the solve? (final sim appears to complete as expected).

Heya Brendan, Amazing! Good to know, I think Your result is closer to 14900k with this test, but yeah awaiting Your final results and I could set it into excel tab for compare. Cheers!

Hi,I’m getting much longer simulation times compared to other users with the same CPU (Ryzen 9 5950X). My RAM 128GB 3200 and X570-A PRO (MS-7C37), Ubuntu 24.04, Kernel 6.14. Houdini 20.5.550 My results:

Pyro:

0.02 - 1h19m 0.05 - 54s 0.1 - 24s

Grain: 0.01 - 14m13s 0.02 - 2m38s

Flip: 0.05 - 52m 0.15 - 1m34s

Blender benchmarks look normal for my system, so CPU performance seems fine. Any idea what could be wrong?
