I am considering a purchase of a Qnap product like the TS-453Be or similar. There is onboard Hardware-accelerated Transcoding but also a PCIe slot. I assume you can use a video card in the slot, please correct me if I’m wrong.
If you can use an nvidia video card, is there any performance difference between it and the onboard Hardware-accelerated Transcoding?
There are but keep in mind you are starting with a a pretty weak cpu, even if you increase the ram to 8GB and go through the adding a GTX/RTX card your results will be limited.
Here is some testing, sadly they didn’t include the server specs, they do list the majority of the Nvidia cards.
