Intel Core i5-1335U vs Intel Core Ultra 5 125U

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, sporting 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
