Hi
I bought a i5 4th gen 4430 pc for a dedicated server, 1 user is transcoding 1080 to 720 , and cpu jumping 15% to 97%…and GPU sit about 7%…normal?
How many streams to u think can i get from 1080 to 1080 and 1080 to 720 ?
Just a estimate please.
Kind Regards
Bertus
Plex Media Server version? See Authorized Devices.
Plex Media Server platform (Windows/Linux/etc)?
What is the video format?
A 4th Gen Intel CPU does not support decoding of H.265/HEVC video. Therefore Plex will use the CPU, not the GPU, for the decode portion of the transcode.
Furthermore, if the video is HDR, it will add additional load to the CPU.
Make sure you’ve enabled both Use hardware acceleration when available and Use hardware-accelerated video encoding in Settings → Transcoder.
Monitor playback via Plex Dashboard → Now Playing. It will show you if Plex is using hardware accelerated transcoding. Expand the view to show necessary details.
Using an Intel 4th gen CPU, Plex supports hardware accelerated decoding of AVC/H.264, MPEG2, and VC-1 video.
When using hardware acceleration and supported video formats you should be able to transcode “several” video streams. I don’t know an exact number, but it is definitely more than one or two.
When not using hardware acceleration, you will get one or two transcodes. The i5-4330 has a Passmark rating of 4639. Per What kind of CPU do I need for my Server?, transcoding a 1080p/H.264 video requires a Passmark of 2000.
Note that many other factors can affect how many concurrent transcodes your server can handle.
Audio transcoding occurs on the CPU. Some audio formats, such as TrueHD, require more CPU cycles to transcode than others. While not compute intensive, it is an additional load on the system and may come into play when transcoding multiple streams.
Burning subtitles into a video stream can place an additional noticeable load on the Plex server. This is in addition to what is required to transcode the video.
Hi
Thx for reply.
version : 1.24.3.5033-757abe6b4
U state 1080p need 2000 passmark per encode? Is it for CPU if GPU is not used?
And is 1080p to 1080p stil using a lot of computing?
Is their other slot 1150 cpu what support H.265/HEVC video?
As far i can see, most users use HW encoding or direct play so far.

As mentioned, that is when hardware acceleration is NOT in use.
We’ve already had this conversation:
Yes, but their i talked about a dedicated gpu card, untill i saw intel cpu support it also with quick sync.
So its cheaper to get a cpu than gpu card.
So is their slot 1150 cpu what can hanlde the h. 265 as mensioned?
Already answered in previous thread.
To transcode 4K HDR movies, you’ll want a 7th gen Intel GPU or later. Earlier versions do not support HEVC video.
If you do not care about HEVC video, you can go with a 2nd gen - 6th gen CPU. However, the quality of video generated by those earlier generations is not the best, especially 2nd & 3rd gen.
Ok. Cause my files is only 1080p and 720p, so upgrade to a 7th gen wont have a impact if i have 1080p max files?
Should be OK.
H.264 will be transcoded using the Intel graphics.
H.265/HEVC will be transcoded using the CPU.
You can add a Nvidia GPU later if needed and the system has an available slot.
