Differences between Nvidia & built-in Hardware Encoding

Hi all.

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?

Thanks for your help!

Even with a GPU/ASIC to handle the video transcoding, the cpu is still used for Audio of which J3455 will be the weak link.

What kind of load did you have in mind, please don’t say 4k.

Oh no, I don’t have any 4k at this point. Although I’ll assume it’s in my future.

At this point it’ll be 1080p at the worst.

No charts showing the differences between hardware versions & different nvidia cards?

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.

I wouldn’t rush to buy an Nvidia card, the new versions of Plex Server have driver requirements that Qnap hasn’t pushed out yet.

Start with using the QSYNC built into the CPU and then evaluate.

Plex lists the TS-453Be as recommended. What other driver requirements do you mean?
