Techtechpotato Youtuber dude's 3DPM beta benchmark

[igor_kavinski]

This is a benchmark doing some commonly used (in the scientific community) algorithmic calculations. The author (PhD so he knows what he's doing) shared beta code on Anandtech which I was able to compile. It seems to scale very well with the AVX-512 capabilities of CPUs despite it not being hand tuned super optimized code.

Binaries can be downloaded from here: https://www.overclock.net/posts/29526304/

It's a quick 2 minute multicore benchmark that can aid in validating CPU/RAM tuning efforts.

Now for some scores!

First up is my sad score (9950X3D 85C temp limit 6000C28 non-PBO FCLK 2167):



i9-14900KF@P8x57- 2x59/E45/R48 RAM 32GB DDR5 7200 CL34 @ 8200 CL36-48-48-2N



Tuned 9800X3D:



domdtxdissar's 9950X3D2 (he holds most HWBOT records with his custom cooled MORA setup):



Anandtech cases and cooling Supermod's watercooled stock Threadripper:

Core i3-1115G4 LPDDR4-3200

Hyperthreading OFF



HT ON

 

[igor_kavinski]

Core i3-1125G4 DDR4-3200



Core i3-1215U (not sure whether it's DDR4 or DDR5)



Yup. Intel shot itself in the foot by disabling AVX-512 in Alder Lake.

Alder Lake memory technology comparison using the same CPU:

 

[igor_kavinski]

Yes. AMD FX-8320 is actually not that bad! But the power consumption is.

 

[igor_kavinski]

Even Ice Lake with single channel RAM delivers performance close to Core i3-1215U. Intel, will you ever learn????

 

[igor_kavinski]

Epyc Rome ES (max 64 threads only due to Windows limitation)

SMT OFF



SMT ON



SMT hurts performance.

 

[igor_kavinski]

Epyc Milan ES SMT off



Both Epycs have a lot of knobs in the BIOS that may lead to better performance. NPS1 and SRAT disabled setting causes Milan to lag behind Rome.

SMT hurts performance.

I mean dude... you're limited to 64 threads... by enabling SMT you might have process threads running on virtual cores which cuts performance by 10% easily for those threads compared to hardware threads.

Otherwise love to see the numbers. Though I'm only partially annoyed that in all of the server class screenshot you omitted the average results. lol.

Not sure what you mean by "average results".

Sorry the Total Score.

Sorry the Total Score.

The total score is there in the Epyc screenshots.

I completely missed it because it was on the right side after the thread ripper where it was more centered.. talk about tunnel vision.

Yeah, that's actually the default position (right side). The other benchmarkers centered it manually. I didn't even know that was possible
