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.

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…
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).
Anyone with M4 Max or M3 Ultra?
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?
