Benchmark performance of Quicksync Intel iGPU on 13900K or 14900K versus NVidia 4080 GPU

[stressedout-tek]

Some Video editing Software suppliers have suddenly switched priority of H264 and H265 decoding from the iGPU to an NVidia GPU in a user's system.

Do any benchmarking tests exist for H264 and H265 4.2.0 video decoding to show performance of Intel Quicksync versus an NVidia discrete GPU ?.

I have always found Intel iGPU faster, but now I have to disable the NVidia 4080 GPU to force decode to  Intel instead on my NVidia GPU.

It would be interesting to see if any actual tests are available in the public domain from Intel to show the benchmarked performance of the two decoding methods for H264 and H265 on iGPU versus say a NVidia 4070 or 4080 GPU.

If anyone knows of such valid manufacturer tests, please post here. Thanks

Hi stressedout-tek,

Thank you for posting in the communities!

Thank you for providing your thoughts and observations about the benchmarking performance of our Intel Quicksync Video.

No worries, I'll try to look on this internally and will provide you an update on this thread as soon as I can.

Best regards,

Many thanks for looking into this for me.

To put this in perspective - many Video editors are always looking to get the maximum potential and performance from their hardware investment - I know I am one of those individuals.

Recently we have been struggling against many variables - with Application Software changes in Video Decode/Encode priorities / Intel driver updates / NVidia driver updates and the awful reputation of the upgrade from Win 11 23H2 to Win 11 24H2

This has all been a real headache and many users are still reporting issues in peformance dropping through the floor.

I am just trying to establish a benchmark starting point to see how Quicksync performs versus a discrete GPU for media that is Hardware decode/encode capable - i.e.: H264 , H265 4.2.0,   8 or 10bit.

I know there are many variable to affect this - some of those even listed above, but as a Chartered engineer before retirement one thing that was paramount we always followed was to establish benchmark test criteria and environment so improvements and performance drops could be demonstrated more accurately with some confidence.

Information for iGPU engines in Raptor, Raptor enhanced and the more recent Ultra CPUs would be good.

I hope you can find some useful information around this topic for us. This is to help users ensure they have the best settings in their hardware platforms.
