He is comparing with Xeon. It doesnt have the UHD630 gpu. The i7 8th gen with UHD630 performs way better than the P2000 from what I understand. Not sure about the i3 in the 672xt though. Thats why Im asking.
Yes unlimited streams and less cpu consumtion. I had one quadro card so i want to use it.
Hey
Thanks for the reply.
The cpu your NAS comes with, the i3 8100t, has intels UHD 630 GPU built-in. It also supports HW transcoding with (as far as I know) next to no CPU consumption. Have you tried using it?
From what I understand, at least in a Windows enviroment, this GPU can achieve better video quality, and better performance (more simultanious transcodes) than the Quadro P2000 you are trying to use instead.
I dont know if this will be the case with a Qnap, but I would love to know, as the very same NAS you have is on the top of my shortlist, as Im am about to replace a 16 bay 19" that sounds like an airplane for something smaller, more silent, and thunderbolt enabled.
From the Plex NAS Compatibility Guide:
QNAP TVS-672XT x64 (Core i3-8100T) 3.1 Ghz Yes Yes Yes Some No Yes Yes Yes SDR Only Decode Only Decode Only
The three right-most colums:
SDR only = 2160p SDR (H.264) (decode from and encode to)
Decode only = 2160p HEVC decode SDR and HDR (encoding to H.264)
Decode only and SDR only?
Is SDR only due to Plex? I thought this chip supported 10 bit colors?
Is decode only a Qnap specific limitation? I wasnt aware it wouldnt encode
Thatâs a bit confusing â for which I apologize.
With 2160p, H.264, it will only process SDR video in hardware.
With 2160p, H.265 (HEVC), it will do SDR and HDR.
The âDECODE ONLYâ is a Plex engineering decision. They do not transcode 2160p HDR to 2160p HDR. (if you think about it, transcoding 2160p UHD to lower bitrate 2160p UHD is kinda pointless and defeats the purpose of having 2160p UHD)
What it does, again I apologize for the difficulty with the tagging,
It will DECODE 2160P HEVC and encode to H.264.
I couldnât figure out how to put all that in single tag
If you scroll to the bottom, you can see a bit better explanation (line 408) in the Legend.
Maybe I should change âDecode Onlyâ to be âH.264 outputâ ?
Whatâs a good way to communicate what itâs doing?

Yea that was a little bit confusing. But now I understand it. The guide should probably try to be more clear, but thanks for clearing it up here
Sorry I still donât understand why i cannot use the card , is there some log where i can see what the plex.sh takes for a card ?
@RockStar The onboard intel chip seems to do well with transcoding video. I was just worried about having multiple transcodes going at once. My family and some friends are not the most tech savvy, and most of them leave the default for plex to be set at 720p. It doesnât matter if they have gigabit internet (as do I), they still find a way to leave it at default. So my 1080p movies are constantly transcoded down to 720p. At one point I had loaded some of my UHD copies up, but it got even worse transcoding 4k content to 720p, and they were complaining about buffering problems.
I added the quadro to help solve some of these problems, but if they are only running 720p, I am just going to let them stream the 1080p titles to take less strain off my server.
@fuuss I havenât had a chance to try the transcoding on the p2000 on my system yet, but will work on that today or tomorrow. Iâll load a UHD copy of something and force it down to 720p locally to see what does the transcoding. I suppose I will have to look in the hardware manager (edit: of the qnap) to see if the card is active. I havenât seen anything within Plex itself to see if gpu is active. The dashboard only shows cpu, bandwidth, and ram usage.

Yea, but will it use both gpus for hw accelerated transcoding when you add the P2000?
I was under the impression that it was one or the other?
Some guy on this forum reported the i7 8700 managed six simultanious 4K transcodes on his windows server. Afaik, the most you will get out of the P2000 is four. Now granted, the i7 he was using is much more powerful than the i3 in the Qnap, but it uses the same GPU. So does that matter or can we expect the same kind of performance from all UHD 630 enabled cpus?
Only ONE will be used: either the QSV ASIC or an Nvidia.
Thats what I though. So the P2000 may actually decrease the transcoding performance in this NAS
It would be interesting if the guys in this thread who has the quadro installed compared the performance
I also reported transcoding 6+ on the TVS-1282T-i7 (i7-7700 CPU) with room to spare in the CPU & ASIC. (I ran out of players)
So two different uhd 630âs outperforming the P2000 so far. I hope more people post findings from these Intel chips. They seem amazing for Plex. Id love to know if the i3 in this box performs equally good.
Separate the CPUâs components:
- i3 / i5 / i7 - The âcrunchâ for normal ops, transcoding audio & burning subtitles.
- The QSV ASIC - The video transcode engine.
- Passmarks of the i3, i5, and i7 tell the crunch story in simple math.
- QSV ASIC - The 7xxx (KabyLake) gave us HEVC HDR. The 8xxx is a refinement.
My testing used 70 Mbps source which yielded 400+ Mbps video input to be transcoded.
If its that simple, the i3 in the Qnap should be a beast for plex usage. I guess the i5 or i7 would be preferable if one needs alot of audio transcodes at the same time or if using subs a lot. Can not wait to get my hands on one of these
The ONE caution with an i3
- 7.1 audio -> stereo ⊠7.1 truehd is CPU-heavy.
- Subtitles. Burning subtitles is hard on any CPU.
Hah. I saw your reply after i finished editing my post 
@RockStar I was under the impression that for my setup, the p2000 could handle up to 17 streams at once on 1080p to 720p nVidia Hardware Transcoding Calculator for Plex Estimates (p2000 is in the GP106 category to filter out most of the other cards). That would leave the cpu to handle the audio portion. I seriously doubt I will ever get that many streams at once; the most I have had that I know of at the same time was 4. Some were direct stream 1080 to 1080, while others were 1080 to 720.
I was under the impression that the integrated intel graphics would only handle a couple of streams before it became saturated, which is why I opted for the p2000. I may be mistaken though and it is more durable than I gave it credit for.
At this time I donât have any 4k content uploaded to my server. I would like to add my 4k content to plex eventually, but from my testing unless I am streaming over wired ethernet within my own LAN, it buffers too much. That is uncompressed mkv with direct stream though, so high bandwidth usage. For now I am leaving just 1080p mkvs on my server, and when I want to watch a UHD disc I just pull and play in my player. That way if it has dolby vision I get that too. None of my family cares what the picture looks like too. They are fine with 720p apparently 
If you arenât in a hurry, once computer components come back into stock I may migrate away from my qnap and sell mine. I am located east coast of US if you are interested. Might be a while till I can build a new server though. Components are hard to get at this point, and prices are laughable high on some stuff.
