Are you sure the IGP is disabled ? in some intel cpus , the video decode block is separate from the main graphics , also even if vp9 is isn't directly supported, if vp8 is , then it may be partially hardware accelerated..

The i5-3470 IGP was completely disabled. It wasn't even showing up in Device Manager.
The i7-4930K is an LGA2011 CPU and doesn't even have an IGP. In GPU-Z, the GTX 970's video decoder was showing 0% utilization while playing VP9.

Update: I just finished building a Ryzen 7 machine for a friend and added results to the chart. AMD's latest is not bad at all, easily beating my 4.6GHz i7-4930K in software decode performance. But what I found most impressive was just how much faster it was than the old 4GHz Phenom X6. Yowza!

The X6 1090T was released 8 years and two whole generations ago. CPU innovation has slowed over the past few years, but advances are still being made. :wink:

And to think I still have an X6 1060T sitting in a server chugging along :O! Just got news a few days ago that we are seeking out a server replacement however.

My home server is still a 1090T. In an AM2+ motherboard (DDR2 RAM), no less. For my use case it is actually overkill; I probably should have something more power-efficient in there, but the 1090T is what I had on hand when I built that server. At least all the cores throttle down to 800MHz under light load, so the idle power isn't that bad.

Maybe I did have the 1090t, now I'm curious. It's in an AM3 platform with DDR3 ECC though. When they retire it, I'll probably use it. They want to go with something more like a Dell this time even though they got an amazing value out of this server, just dead rock solid for 8 years. It is in my favorite case in the world to build in, the Corsair Carbide 600t. Heck, I might even move my main rig into that case and re-purpose the 400r.

That was one of the cool things about that generation. The dual-mode memory controller allowed you to re-use your old AM2+ mobo and DDR2 RAM (BIOS support permitting), or go AM3/DDR3 if you were willing to spring for an entire new platform.

Hmm... I wonder if swapping out the motherboard in that system would reduce the power consumption by a meaningful amount. I have a spare AM3 mobo and some DDR3...

I'm still using a Core Duo T2700 in my server. Not the Core 2 Duo; rather, the old 32-bit "stopgap" Intel was putting in laptops to compete with Turion X2 before Core 2 was ready. It's not the fastest thing in the world, but perfectly adequate for what it needs to do.

Curious if this is spreading the load a little or just stressing 1 or 2 threads.

Re: Let's take a look at the VP9 decoding performance of 20 different processors!

I started testing software HEVC decode performance on a few of these processors. So far, I've only tested the playback of a 10-bit 1080p/24 HEVC encoded file, but will eventually add 720p, 1080p/60, 2160p/24, and 2160p/60.

The results are quite interesting, and it looks like SSE4 really helps out.
All of the tests were performed under Win7 Pro SP1, and the HEVC decoder was LAV 0.70.2.1 (built into MPC-HC 1.7.13). The video file was a 24 fps 1920x1080p (1.78:1 AR; no letterboxing) HEVC 10-bit encode, with an average bit rate of 12 Mb/s. The audio track was Dolby Digital Plus 5.1 at 1.5 Mb/s.

Pentium D 935 @ 3.2GHz (Max. supported instruction set: SSE3)
2 x 2MB L2 cache, 800MHz FSB
4GB of DDR2-667 dual-channel memory
CPU usage: 100% - video appeared to be playing at half speed, and was falling far behind the audio track.
Note: This CPU has absolutely no problem playing H.264 1080p files in software.

Core Duo (Yonah) T2500 @ 2GHz (Max. supported instruction set: SSE3)
2MB L2 cache, 667MHz FSB
2GB of DDR2-667 dual-channel memory
CPU usage: 100% - Again, video appeared to be playing at half speed, and was falling far behind the audio track.
Note: This CPU has absolutely no problem playing H.264 1080p files in software.

Core 2 Duo E8600 @ 3.33GHz (Max. supported instruction set: SSE4.1)
6MB L2 cache, 1333MHz FSB
8GB of DDR3-1333 dual-channel memory
CPU usage: 21-37%

Core i7 4930K @ 4.6GHz (Max. supported instruction set: AVX)
12MB L3 cache
32GB of DDR3-2400 quad-channel memory
CPU usage: 2-3% (yes, that's without hardware acceleration)

Will add more CPUs as I get the time to test them.

Kids use core2quads in their desktop machines and watch streaming video on occasion. (netflix usually)
They prefer to use their laptops which are 2 or 3rd gen mobile core i5's the video seems to play back a bit more smoothly.
Main machine: Core I7 -2600K @ 4.0Ghz / 16 gig ram / Radeon RX 580 8gb / 500gb toshiba ssd / 5tb hd
Old machine: Core 2 quad Q6600 @ 3ghz / 8 gig ram / Radeon 7870 / 240 gb PNY ssd / 1tb HD

Did you turn off GPU decoding completely in MPC? Most stuff I use hits the NVEncoder on my GTX 1080 these days.

also, I tried going through some of my stuff to find an HEVC file real fast, god Windows Explorer sucks.

Yeah, and I even slotted in my old GTX 970 to make sure that no hardware decode was taking place.
With the GTX 1080Ti and hardware decode enabled, CPU usage drops to 0% and stays there.

I guess that with any halfway decent CPU, even an older one like my overclocked 4930K, hardware decoding is completely unnecessary for HEVC 10-bit. It'll be interesting to see how this CPU copes with 60 fps 2160p content, but I'm guessing it'll have no problem at all, based on the 2-3% CPU usage at 1080p/24.

I'd say that even the old E8600 has a real chance of handling 24fps 2160p HEVC in software!

For those like are still using old computers like me (c2q) the best is use Netflix app in win 10, not browser, and use edge instead of chrome, that activate h264 instead vp9, for YouTube videos.

I have run a vc1 test in my computer with firefox and it takes only 20-30 of the cpu with no hardware acceleration.

It could be good to add this new codec to your list as it looks that the worst for old computers is vp9.

Not sure why YouTube pushes people to VP9 also when there's no hardware acceleration.

I think it's Google trying to force the market away from patented stuff. All very nice in theory, but not when in practice it hurts end users.

I don't think it's hurting too many users, when even a 12 year old E8600 can handle 1080p/60 or 1440p/30 without GPU acceleration. Anyone using a processor older than Core 2 probably isn't too concerned about 4K streaming anyway. :P

Even if a CPU can, there's a difference. More chance of skipped frames, higher CPU load could mean more audible fan noise, higher battery drain, less CPU for other tasks running in the background...

Hardware acceleration happens when a thing becomes popular. I haven't done much research on VP9 to see if it merits the kind of popularity h264 has seen. This could very well be completely justified, but megacorps often decide what they want to make popular regardless of its merits.
Do not meddle in the affairs of archers, for they are subtle and you won't hear them coming.

What is love?

I think it's bitrate that's really important. Those old procs will be a lot less happy when given a 50Mbps file (basically UHD Bluray raws). And to complicate stuff further NVENC seems to be capable of partially accelerating video decode even on Kepler era cards. I remember running DXVA checker on a GTX670 and it showed a significant amount of stuff as being hardware accelerated. Will post a screenie when I pull that rig out.

It's ALL about bitrate. I could (more or less) give zero ducks (I actually typed ducks) about the codec used for the most part as long as the bitrate is high enough I don't see any crappy blocking/artifacting.

At first, I was concerned that the GTX 680 and 970 GPUs in some of the machines was partially off-loading the decode process. However that doesn't seem to be the case.

Using the C2D E8600-based machine, I tested VP9 playback with the GMA X4500HD IGP, a GTX 680, GTX 970, and GTX 1080Ti. Only the GTX 1080Ti significantly lowered CPU usage and made 2160p/60 completely smooth.

Same results with HEVC playback. CPU usage was reduced only when the GTX 1080Ti was installed (MPC-HC's playback status also indicated that HW was being used--which it didn't do with the IGP, GTX 680, and GTX 970).
