New GPU vs. new CPU

[Peter]

The ffmpeg commandline parameters are set to allow auto configuration of the number of threads to use when transcoding and this affects the number of cores used. Using extra cores does not necessarily equal faster transcoding because the bottleneck can be elsewhere such as disk read/write speed. Also if the media files are stored on a NAS this can also affect transcoding speed.

I can peg the CPU when it transcodes to h264 (plenty of fps) so it's not a HDD bottleneck, but if it is transcoding to VP9 for web streaming it just crawls at 33-34%.

I recently bought AMD E3 V2 and GeForce GTX 1050 Ti but the graphic card is not working on that machine. Is this card not compatible with that machine?

What is an AMD E3 V2?

Peter, I looked on Reddit for some help on my hardware roadmap and someone with a lot more knowledge on video encoding mentioned that libvpx has been updated to support 8 threads instead of just 4 when encoding to VP9. Is this something that can be updated by getting a newer version of FFMPEG?

Yes getting a newer version of ffmpeg could help but this may also break transcoding in Mezzmo if the commandline parameters to ffmpeg have changed. You can get a newer ffmpeg version from https://ffmpeg.zeranoe.com/builds/ and then change the path in Transcoding settings to the path to the new ffmpeg to see if it works.

I've completed a couple of my AMD hardware upgrades to Ryzen 3000 CPUs. Here's some comparisons using FFMPEG doing 24 mbps H264 encoding.


27 fps - AMD FX-8350 1080P H.264
48 fps - Intel i7-4790k 1080P H.264
123 fps - Ryzen 3800X 1080P H.264
354 fps - Intel i7-4790K 1080P H.264 w/Nvidia 970 GPU

I've done one more upgrade, my video card from a GTX 970 to a GTX 2070 Super card. Here's the updated results:

27 fps - AMD FX-8350 1080P H.264
48 fps - Intel i7-4790k 1080P H.264
123 fps - Ryzen 3800X 1080P H.264
354 fps - Intel i7-4790K 1080P H.264 w/Nvidia 970 GPU
535 fps - Intel i7-4790K 1080P H.264 w/Nvidia 2070 Super GPU

The bottleneck becomes how fast the GPU can decode the source file. The decode process is running the GPU at 100%. The source is a Blu-Ray ISO. If I move down to DVDs I can get fps rates over 1300fps.
