It does not use AVX512 by the way, Tigerlake could perform like 3-4% faster using AVX512.

Interesting to note that your average effective clock speed went below the base frequency while mine didn't.

The effective clock speed is a bit under the base because of the first and last seconds when it isn't fully loaded and the CPU utilization overall is like 98-99%. If you deactivate your CPU Turbo your effective CPU speed should be a bit lower than the base. I did disable the CPU Turbo because it's easier for a stable performance testing.

How do you disable turbo boost? I don't think my BIOS has an option to do that.

Actually the AVX512 speedup is a bit higher in this test.

What laptop models do you guys have? I think it might be nice to have that info in the chart.

mikk,

I'm not quite following the avx thing. Is there a way to enable this in Handbrake? Could you bring me up to speed on this?

Yes it can be enabled in the video tab with the parameter asm=avx512

It's disabled by default, at least on Tigerlake. I have a Dell Inspiron 15 7506.

I'll do a run later today with AVX512 enabled. My laptop model is a HP 14s-dr2006tu.

Looks like AVX512 gives worse performance due to downclocking:

encoded 1806 frames in 899.81s (2.01 fps), 11820.04 kb/s, Avg QP:29.09
Average effective clock speed: 1970 MHz
Total CPU usage: 89% average

But on the flipside IPC or in this case PPC(performance per core) per gigahertz is 0.255, which I believe is the highest so far.

Edit: @Hulk could you add my and @mikk's AVX512 scores as a separate bar in the chart?

Ive been tweaking my work rig today so I figured I'd give this a go for funsies

5600x all stock with the stock cooler
16gb cl16 running at 3800mhz
Avg. Effective clock 3798 mhz
Avg. total CPU usage 96.8%
Results: encoded 1806 frames in 330.50s (5.46 fps), 11820.04 kb/s, Avg QP:29.09

Done.
Your efficiency score seems really high compared to the other Tiger Lake and my Kaby Lake R w/wo AVX512. Can you double check that?

And yes, AVC512 loads the heck out of the cores and for laptop systems, which are already thermally constrained the situation gets worse.
I took my Surface Laptop 2 into my 40 degree F garage and the clock went up a few hundred MHz. Then I enabled AVX but couldn't hold the same clock so my score ended up about the same.
My Kaby Lake R is 5% more efficient with this test using AVX512.

One thing I'm wondering is the value in purchasing products higher in the stack for laptops, which as I wrote above are thermally constrained.

Let's consider the following CPUs.
downupmax
1135G79002.404.20
1165G71.22.804.70

In a laptop that can let's say dissipate 15W how much faster under full load with all cores loaded will the 1165 operate vs the 1165? Or will they both be constrained at the same point?
Now I realize that the higher binned 1165 should have a voltage/frequency curve that allows for higher frequency at lower voltage and hopefully power but who knows if you are really getting what you are paying for?

I would assume the single core clocks are more attainable since less power overall needs to be dissipated. But again no one seems to test this with two identical laptops, one with fastest CPU and one with slowest.

@Hulk, the efficiency is high because the clock speed is so low, though you're right I should double-check and will probably do so if time permits.

The main reason for downclocking is the fact that this is an all-core load, which is not what you'd want while running AVX-512, and the fact that tau on my laptop is set pretty aggressively. Too bad I can't disable Turbo Boost like @mikk can on his Inspiron.

I'm sorry to be a drag but I'm not totally following here. Can you break it down for me a bit more please?

Kabylake shouldn't be there in the AVX512 list because it does not support AVX512, it's just for Icelake-U, Tigerlake-U or Skylake-X. You can check this in the log:

x265 [info]: using cpu capabilities: MMX2 SSE2Fast LZCNT SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2

This is what you should get on a Skylake based device. And this is Tigerlake-U:

x265 [info]: using cpu capabilities: MMX2 SSE2Fast LZCNT SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2 AVX512

I know AVX2 is basically half the speed of AVX512 so that's what's going on here right?

Tau refers to the amount of time the CPU spends in PL2 before dropping to PL1. It is a part of Intel's TDP spec and is set by OEMs depending on the thermal capabilities of the laptop/desktop design. In DIY space motherboards, especially high end ones, typically ignore it, allowing you to run at PL2 all the time as required.

As you can see in my screenshot avg core speed is 4.2 GHz.

Thanks for submitting your score. We're reporting average effective clock not average clock. Reset just after Handbrake starts encoding and then report the average effective clock value right before it finishes encoding. Would you mind doing this?

Average Effective Clock screenshot at 93% done.

Which " average " column number you want ... is questionable....
Averages ... of averages ... are not accurate.

This test is not pushing the limits of this chip.

I'm expecting an ALL core OC of 4.65 GHz
( not testing yet )
Will submit when All Core found.

( this is a BOOST score )
