Faster Encodes with threads=32

Post by wyliec2 »

Description of problem or question:

I'd heard that there is a limit to the number of threads that Handbrake can use. My platform is Ryzen 3950X with 16 cores/32 threads. When doing large numbers of encodes, I run two instances of Handbrake simultaneously with typically 80+ % CPU utilization. Now that my large set of encodes is completed, I'm more interested in single instance performance and possibly swapping CPU to a Zen 3 5900X (12 cores/24 threads).

I've been using HB without any "threads=" parameter and had assumed it would use all that it could. In testing with different values I was surprised to find reduced encode times with values of “threads=24” and “threads=32”.

Example – BluRay movie 1:29:27 in length. RF=20.5 DTSHD MA 5.1 Pass-thru Audio; Preset: Very-Slow; Profile: High

Default (no “threads” parameter: 41:18 (minutes:seconds)
“threads=32”: 34:03

“threads=0” gives the same results as with no “threads” parameter.

In several different files, threads=32 has given 12%-23% reduced encode times compared to the default.

Steps to reproduce the problem (If Applicable):

Encode the same file with identical settings aside from “threads” parameter.


HandBrake version (e.g., 1.0.0):

1.3.3


Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

Windows 10 Professional – Version 2004

You are using the x264 encoder, which I would expect to be happy around 6-8 logical processors.

Diminishing returns doesn't mean no returns, so it continues to scale.

Default threads for a 16c/32t chip would be 48 (1.5x), so constraining it here with medium-resolution content helps a little bit.

Re: Faster Encodes with threads=32

I've seen the 6-8 logical processors (threads) statement in a few places....given the number of CPUs today with 10+ cores (20+ threads), I wonder if the common suggestion should be clearer that significant gains are available utilizing additional threads and noting that the parameter must be used to access them...???

With a 15-minute BluRay file I got:
6 threads = 23:38
8 threads = 18:05
16 threads = 13:02
32 threads = 7:51
With the full movie example the results are:
16 threads = 1:07:50
32 threads = 34:03

I'll be interested in seeing what the full movie 8 thread result is. The 32 thread result was twice as fast as the 16 thread job.

"Diminishing returns" is obviously a relative term and performance isn't proportional to the number of threads used, but it appears that modern CPUs may be able to complete encodes in 1/3 - 1/2 the time of the "happy" platform specification.

I just encoded a new movie with threads set to 32. Over the course of the encode, my PC averaged 78.7% CPU utilization with peaks near 90%.

In months of reading Handbrake "best practices" and performance discussions, it was never apparent this much untapped performance was available!

I'm not an expert, just trying to understand the results I'm finding.

This is a quote made to a user with a 12 core/24 thread processor just a couple of weeks ago:

"For example, using x264 as your encoder will limit the number of cores used to less than the 12 you have, because more threads do not help."

I value this (and other) forums as a reliable source of information. I try to contribute to the collective knowledgebase when there appears to be a gap.

Since you have an interest in objectivity, which is a rarity in public forums, and since your results are different than many of us have been led to expect, they would be most helpful if you posted your test procedures and reproducible results, and let others try their hands using the same criteria. I'm sure the developers won't mind you posting them in the Tiki Bar, as some of us have done with other types of tests. Interesting stuff, and I am glad you are sharing quantified evidence, rather than just impressions.

mduell is correct, automatic thread selection with x264 is 1.5x the number of logical processors (unless you enable slice-based threads, but that's only useful in low-latency real-time encoding scenarios), so 48 in this case, which would give (in your testing):

6 < 8 < 16 < 48 < 32

The statement should read that more than 6-8 threads has diminishing returns. Diminishing meaning each additional thread adds a little less performance than the prior. So doubling the thread count again will not double performance. That does not mean that the additional gains are 0 or near 0; it just means they're not 100% or near 100%.

And that's what you found; each time you doubled the number of threads, you got about 50% better performance. But eventually this will not be true, as you found from 32 to 48 performance goes down a little.

HB most certainly can and does spawn more software threads than the CPU has hardware threads.

The default is 48 threads for your chip, so by setting it to 32 threads you're constraining the number of threads. As you found, with your combination of source, settings, encoder, and CPU, this can be advantageous.

Thanks for your detailed reply!

I will note that in the full movie example going from 16 to 32 threads was 100% improvement - I could encode the movie twice in the same length of time using 32 threads. This is for that ONE example only. With limited testing, I've found there to often be a near 100% improvement at some point - sometimes 6 to 12 threads or 8 to 16 threads. Other doublings will produce significantly less and I have examples where 24 threads is sometimes faster than the default and sometimes slower. Other times the difference between 24 and 32 threads is just a few seconds.

I have approximately 2000 movies (encoded from mostly bluray folders to MKV) on a media server. My two priorities are filesize and quality - meaning I take what I can get for encode times and will always look for performance opportunities.

At the suggestion of musicvid, I've played around with the Tears of Steel .mov content on the Benchmarks page. Interestingly, the parameters for benchmarking the 1080p file in H.265 produce EXACTLY the same encode times whether at default or threads=32. When I use my standard settings of H.264 + Very Slow, I get results more similar to the examples here.

I can see where with some setting combinations, it seems there is a 'hard' limit beyond which adding cores (whether it's 32 or 48) does nothing. It appears settings that drive a more intensive compute workload may benefit from a 32-thread specification - I'm still trying to wrap my head around the '6<8<12<16<24<48<32' situation.

Are there scenarios in which assigning more logical tasks than there are actual processors is an advantage??

I'm a bit skeptical of your full movie results, especially with only 16 cores; may be influenced by other things you were doing on your computer at the time.

Again, the exact result is going to depend on a lot of factors: turn the wrong (or right) filter on, and suddenly there will be no difference from 4 to 40 threads; encode some lower resolution content and it may have very small differences from 10 to 30 threads; etc.

Re: Faster Encodes with threads=32

Sorry - I'm back with more results....

And I'll be blunt - you skepticism is an incorrect speculation. I've spent a lifetime in a variety of technical endeavors which have all demanded meticulous methodology - I wouldn't waste my time compiling half-baked data or your time discussing it. The PC platform is a dedicated encoding machine (long story) with NOTHING else running on it aside from a couple of monitoring processes which track CPU utilization, core voltage, CPU and CPU package temps, CPU package power....total < 2% CPU utilization. I purpose-built it with selected components as I have several other PCs and servers.

Specifics of my testing are:
Source - tears_of_steel_1080p.mov; 12:14 duration; 570,092 KB
All filters OFF
H.264(x264)
Constant Framerate - Same as Source
Constant Quality - RF = 20.5
Preset = VerySlow
Tune=None
Profile=High
Level=4.2
Optional Params= ref=5:bframes=5(:threads=xx)
Audio=mp3 2ch set to auto passthru

Results of testing:
1) 5:26 - no parameters 'default'
2) 4:36 - threads=32
3) 8:55 - threads=16 (again, with these settings, 32 threads yields near 100% improvement)
4) 4:04 - threads=48 (I had expected this to match the no parameters default so this was a surprise!)
5) 5:29 - threads=24 (just to complete the series)
6) 4:10 - threads=40 (the threads=48 result had intrigued me)
7) 5:23 - no parameters 'default' (close enough to validate the first result)
8) 3:54 - threads=60 (just for the sake of experimentation)

Again, these are with the specific file and settings specified. They are definitive results with the only variable being the thread parameter value or simply the lack of the thread parameter.

With these settings - the default does not seem to be 48 threads.

I'm still not clear on how assigning HB thread counts beyond actual logical processors is beneficial - it does continue to produce reductions in encode times.

I read one claim (possibly on REDDIT) that too many threads can get out of sync and cause audio problems - any input regarding that suggestion?

Being largely retired aside from some P/T analytics work, I enjoy a respectful and articulate dialogue on perplexing technical matters....FWIW.

I should have qualified the specifics of my platform:

AMD 3950X 16 core/32 thread CPU
ASUS ROG Crosshair VIII Formula motherboard
32 GB G.Skill 3600/CL16 RAM (2x16)
Gigabyte 1050 TI GPU - CPU doesn't have IGPU so minimal GPU required for display

I do have a moderate all-core overclock to 4225. I could expound greatly how poorly Precision Boost Overdrive works for productivity applications - of course it's targeted for gamers which I don't do. 4225 gives me stable operation under 70 degrees C which I prefer since at times I have run dual HB instances for several days straight at >90% CPU utilization.

Wondering if you had seen the later results in which the default (no thread parameter) produced clearly different results than a threads=48 setting? All on a dedicated machine with nothin else running and with identical settings aside from the threads parameter....

Re: Faster Encodes with threads=32

Post by nhyone »

Have you compared the file size? When you use more threads, the file is slightly larger due to reduced encoding efficiency.

You get the smallest file with 1 lookahead thread, and that roughly limits you to 6 encoding threads. (More is useless as they are starved.)

Between 6 threads and 32 threads, the size difference is around 3-5%, iirc.

So I just encode multiple videos concurrently.

I'm surprised with your results that 32 threads is twice as fast as 16 threads. Given that it is a 16-core CPU, the hyperthreading must be very good. On my old Xeon setup, HT cores only give maybe 15% speedup. If 16 threads takes 100 mins, then using 32 threads only reduces it to 85 mins.

Interestingly, from your tests, using more threads lead to smaller file size:

Code: Select all

threads 16  414,238,554 bytes, 4,513.58 kbps, P:5080  Avg QP:21.57  size: 50906
no threads  407,813,731 bytes, 4,443.58 kbps, P:5280  Avg QP:21.67  size: 48563
threads 32  402,261,720 bytes, 4,383.08 kbps, P:5473  Avg QP:21.77  size: 46536
threads 48  397,041,015 bytes, 4,326.19 kbps, P:5738  Avg QP:21.91  size: 44187
threads 60  394,966,074 bytes, 4,303.59 kbps, P:5846  Avg QP:21.98  size: 43364
From the logs, I think the main reason is that the P frames are of slightly worse quality when more threads are used.

(From the looks of it, x264 defaults to max 20 threads if not specified?)

"approximately 2000 movies (encoded from mostly bluray folders to MKV) on a media server." - defo want to be moving to H.265

Prob best to only run one instance of HB, and keep testing with threads as you have been. Your GPU could perhaps be Upgraded and use of HW acceleration on BOTH the CPU and GPU is most important.
"80+ % CPU utilization" - this is good.

My Q is that, within the encoding process, when you change the number of threads what is the quality and size of the resulting output files? When you take 1 identical source and output several versions to compare.
