H.264 DXVA Benchmarks: QuickSync vs UVD 2.2 vs VP4 vs VP5

[nevcairiel]

For the two clips you mentioned. Benchmarked with DXVAChecker 3.0.1 in EVR renderless mode, on my HD4600

Cat:

LAV DXVA2-Native: 981 fps
MS DS: 960 fps

Vortex:

LAV DXVA2-Native: 410 fps
MS DS: 372 fps

Important to note is that the MS DS decoder seems to generally have at least twice as much CPU usage according to DXVA Checker.
Of course all VPP options are disabled, I double checked just in case.

[NikosD]

No.

Not EVR renderless, in EVR option.

[nevcairiel]

That only brings the results closer together

Cat: LAV 783 fps, MS DS 778 fps
Vortex: LAV 291 fps, MS DS 290 fps

Note that I run every file 6 times, then take the average from the last 5 runs (ignoring the first, since it always varies a lot)

[qtwebkit]

I've also tested the two clips, in nevcairiel's method - 6 times for each and abandon the first time.

OS: Windows 8
Graphic: HD4000
Render: EVR
Mode: DXVA2 Native
LAVFilters: latest nightly
DXVA Checker : 3.0.1

Cat:
LAV : 256.4fps 9%
MS DS : 262fps 12.4%

Vortexx:
LAV : 180.6fps 11.2%
MS DS : 157.4fps 17.6%

Hmm...I got a result different from both of you
If you would like to see results of MPC-BE and ArcSoft, see the detailed material here.

[NikosD]

Your results are too low for both clips, for both decoders and for HD 4000.

I'm pretty sure you haven't disabled all VPP functions in Intel's control panel.

[qtwebkit]

I checked it before testing and made sure the options you mentioned is set all right.
I think maybe it's the driver problem. I've tried many times to update the Intel graphic driver but all failed with BSOD or black screen... hence I have to use the old oem driver plubished in June 2012.

I'm going to update to Windows 8.1 and try again if the new driver works properly.

[NikosD]

OEM driver from 2012?

You have to update it ASAP.

Maybe it's time for a format or even better a Win 8.1 upgrade.

The progress is great between those 2012 drivers and the nowadays drivers.

[qtwebkit]

Yes, I'll handle it immediatly. As soon as I finnish, I will test again and post my result, maybe tomorrow.

Things become more complicated as I upgrade to Windows 8.1. The performance seems benifit little from the new driver(Jan 28,2014), about 277fps for in Cat and 180fps in Vortexx for LAV, merely no improvement in Vortexx.

I've just found something else maybe ralated to this weird problem. I try to run the decoders with EVR Renderless, the result is much closer to nevcairiel's.
Cat:
LAV : 677fps
MS DS : 682fps

Vortexx
LAV ： 297fps
MS DS ：253fps

But EVR Renderless shows nothing but a black screen during benchmark, while EVR will show video but end up with a very low score

[qtwebkit]

A friend tested the two clips with his HD4000, Windows 8.1 x64, both x64 and x86 filters, but result very close to mine.

performance of x86 filters(x64 scores quite close to x86)
Cat:
LAV : 290fps
MS DS : 293fps

Vortexx:
LAV : 198fps
MS DS : 187fps

Despite the small gap between our results, we are both too slow comparing with yours.

And the same problem, or bug? Black screen in EVR renderless.

[nevcairiel]

EVR renderless is not supposed to show an image.

Hmm...but our score in EVR renderless are extraordinary high (for me Votexx could reach 1500fps with no cpu usage), for some specific clips.

Can you post again which is your CPU ?

Can you see the clock of iGPU with GPU-Z for example, during benchmarking ?

HD4000 should be faster than my GT1.

Are you sure you have an HD4000 and not an HD2500 ?

Not even these numbers are fast.

For me LAV is 340 fps for EVR renderless and Vortexx

Right

EVR renderless shows maximum potential of decoder, because it doesn't have to display the decoded frames, that's why the screen is black and you could go to 3000 fps or more for low resolution/ low bandwidth clips.

[qtwebkit]

My CPU is i3-3110m


Cat


Vortexx


Hope these information would help.

[NikosD]

Well you do have HD4000 with 16 EU's while I have 10.

Your iGPU goes to maximum at 1GHz which is 10% slower than mine which goes up to 1.1GHz.

All of the above don't explain your inferior performance compared with my GT1.

I have to repeat myself just one more time because I can't think of anything else.

Are you sure that ALL VPP functions are disabled in control panel ?

They can push performance down A LOT.

[qtwebkit]

Yes，I'm quite sure everyting in the 3 options

VIDEO - > color enhancement, VIDEO -> Image enhancement, VIDEO -> Image scaling

are toggled to "Application settings" and "OFF"

I've been trying to exclude my omissions and turn to my friends for help, who also did all the settings as you said, but end up with the same problem .

Thank you for your concern on my problem, as well as nevcairiel.

[qtwebkit]

I wonder if it‘s the CPU's problem? Since we both use mobile processors, while yours is for destop.

[NikosD]

Can you benchmark this ?

ftp://helpedia.com/pub/multimedia/x264/testvideos/2160p%20samples/DucksTakeOff_2160p50.x264.CRF24.mkv

It's an UHD file so you have to check 4K box in LAV properties.

[qtwebkit]

It seem DucksTakeOff could not be tested in MS DS.

EVR
LAV : 67fps
MS DS : failed

EVR Renderless
LAV : 126fps
MS DS : failed

[NikosD]

Mine are: 99/146

There is a bottleneck in your system, but I can't tell where.

I tried it and it really works!

QuickSync encoding with Pentium G3420!

2) HEVC_VLD_Main appeared while enumerating DXVA device decoders !!

Can you check this driver: https://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=23644


It is the first official driver with API 1.8 support, maybe there is something different for decoding as well.
