Intel Core i5-1335U vs Intel Core Ultra 5 125U - mavvy - 2024-05-23

Hello, I'm new to Jellyfin, great piece of software!

Currently my Jellyfin setup is running on an old Mini Barebone with an Intel i3-7100U (Intel HD Graphics 620) which so far is enough for 4K transcoding (up to 3 streams with tonemapping) if ever needed (I only tested it locally in 3 browser windows... the 4th window make everything stutter).

Now I am about to upgrade that machine with a newer one, as I need a little more power for other parallel stuff (some Windows software, retro games emulation etc) and the new machine I was planning to order will run on an Intel Core i5-1335U (Gen 13, Raptor Lake) which has an integrated Intel Iris Xe Graphics GPU. Both the new CPU and GPU should give an enormous boost compared to the i3 in daily usage.

I just found out, the new machine which I haven't ordered yet will be replaced by a successor soon, sportingĀ a newer Intel Core Ultra 5 125U (Gen 14, Meteor Lake, same Intel Iris GPU).

Now my question - only regarding Jellyfin - is:
Is it worth to wait for the updated model?

In terms of codecs there are a few differences on the Intel Quick Sync Video Wiki I found:
https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video

MPEG-2
Raptor: YES
Meteor: Decode only

VC-1
Raptor: Decode only
Meteor: NO

AV1
Raptor: Decode only
Meteor: YES

AV1 10-bit
Raptor: Decode only
Meteor: YES

AV1 12-bit
Raptor: NO
Meteor: Decode only

Does YES mean that Jellyfin can de- AND encode? Seems Intel Gen 14 has gained some new codecs but lost some other instead.
What about "Decode only"? Does it mean it can play the codec but not use it for hardware supported transcoding but only software?

I would like to know if you think it will be worth to wait a bit and upgrade directly to Meteor Lake (only regarding benefits for Jellyfin)?

Thanks guys

This table has all the answers.

https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video#Hardware_decoding_and_encoding

FWIW, if you don't need AV1 encoding, either is fine. Having said that, 10.9 now supports AV1 encoding. Only really matters if you are bandwidth restricted for remote users.

Yes, that's the Wiki table I based my findings on.

I wasn't sure about the missing hardware MPEG-2 and VC-1 encoding in the latest Gen 14 Intel CPUs and if I will miss that feature in any situation on my Jellyfin setup. I am guessing that the latest CPU will do fine with software encoding these codecs.

Very good to know that 10.9 will do AV1 encoding now, thank you very much.

Jellyfin only encodes to H264, HEVC, and AV1. So not having encoding support for those doesn't matter. And I can't think of a non-Jellyfin situation where you'd want/need to encode to MPEG2 or VC-1 in 2024 anyway. Even with CPU encoding, because of how simple those codecs are it would still encode on a modern CPU very quickly.

Perfect, thank you, then I will just go for the current CPU generation instead of waiting.
