nVidia Quadro P4000

[thunderclap 52]

I'm currently running Emby in docker on Unraid and have it configured to use the Core i7-9700K Quicksync. A friend is offering my an nVidia Quadro P4000 and I'm wondering if I'll see a significant boost in transcoding. Thanks.

HI, yes I think that would be a healthy upgrade.

It will be faster, yes, but your 9700k has slightly better quality when it transcodes. So it's a trade off.

It also depends on what you mean by 'boost'.

The 9700K has a UHD630 GPU - so it's only 1 generation behind the latest, so I think you'll find it can still punch well above it's weight for transcoding - and you should easily be able to get 8-10 x 1080p simultaneous transcodes, or 3-4 x 4K simultaneoustranscodes.   Certainly good enough for typical home use.

The P4000 has 8Gb fixed memory, meaning however you want to cut it - you cannot use more than this.   Typically speaking, 4K transcodes need ~1Gig each, so you are limited to 8 regardless of how well the card performs.   On the other hand quicksync uses a configurable portion of the system memory - so on a 16Gb system, it may use 8, but on a 32Gb system it could use 16Gb as Video memory.

In summary, I'd stick with the 9700K and use quicksync.
