Info Upscayl CPU benchmark (much improved with recompiled DLL)

[Hail The Brain Slug]

Wow. That seems VERY impressive.

I disabled SMT to see if it would be any faster. It was not. The CPU reported 95-100% utilization in task manager and clearly ran slower.

It definitely will use more than 16 threads, it just can't meaningfully scale up to 32.

 

[igor_kavinski]

Great! It still has some blocking limit in the thread count. It does not go above 41% utilization for my Epyc 64c/128T CPU.

It's using this for multithreading: https://github.com/google/marl

May have to take a closer look at it to see what the limiting factor may be.

Core i3-1125G4: 1 hour 14 minutes

Reduced to 20 min 3 secs

 

[Det0x]

2min 33sec

Thanks, Det0x!

Seems this is one of those "hard" benchmarks where squeezing more performance won't be easy without tinkering with the source code itself.

 

[igor_kavinski]

@511 I think your 185H can slot in between the 245KF and the Epyc.

If you run the benchmark, make sure to do it on AC power and max performance mode.

 

[511]

HT was OFF

 

[511]

HT ON PL1=50/PL2=51W

 

[igor_kavinski]

PL1 is 50W?

 

[511]

PL1 is 50W?

Yes lol 502 was a mistake

 

[igor_kavinski]

Did not expect this CPU to finish so quickly at only 3.56 GHz max boost and 41% overall CPU utilization.

Possibly more RAM bandwidth or AVX-512 optimization by the VS compiler could be the reason.

I should use the ICX/ISPC Compiler

I would be very interested in your results. You just need to compile the vk_swiftshader.dll from the Google source code and then rename it to vulkan-1.dll and replace in root folder and bin folder of Upscayle.

How many tasks or threads can it run at once ? I may try my 9755 on this

 

[igor_kavinski]

I think increased RAM bandwidth factors into the performance (DDR5-9400C42): https://www.overclock.net/posts/29512408/

My 9755 uses only 4800 but 12 channels

Yeah, it's worth a try. Make sure that the NPS setting is at zero in the BIOS. Epyc performs twice as slow with NPS4.

The benchmark behaves weirdly on different systems.

On my Epyc Rome, it showed around 15 threads pegged at 100%. On Ryzen 9950X3D, it was spread over all the cores with lower CPU utilization. On the Xeon 6248R, it was again spread out over the cores, not maxing any cores at 100% as far as I could see but still managed a decent score.

What about your 128 core (2 x 64) Milan ?

I will get to building it, eventually. I want it to be fancy with AIO cooling and I found something cheap (Coolermaster TR4 cooler that is supposedly compatible with SP3 socket) but not cheap enough to get two of them at once in a single month

If TR4 looks like SP3 I am pretty sure I have used the same cooler on both. My threadrippers (ols, were 1950x I think they were) are in fact the same cooler as my early EPYC's.

Here is a pic of that system. I still have it ! @igor_kavinski

Hope the table in the original post pleases you good folks

Sorry @Det0x but I made 2m11s

 

[Det0x]

As i thought, fiddeling with settings

 

[igor_kavinski]

WHICH SETTINGS????
