I can’t find any info googling it. My question is simple- are the higher end processors much better at HW transcoding, or are all Kaby Lakes similar in HW transcode?
I have a Pentium G4560 and thought about dropping in a higher end processor- this one gets pretty choppy at about 5 transcodes. Thanks!
As I understand it, all CPU’s of the Kaby Lake generation have the same QuickSync unit.
But this Pentium has only 4800 passmark points.

It is entirely possible that you will get a few more transcodes if you get a higher-end Core i5 cpu of the latest generation, like for instance this baby here:

Whether it will fit onto your existing motherboard is an entirely different question. You need to verify that with the manufacturer.
Or whether the cooling system is able to handle the increased heat dissipation. (54 W vs. 65 W)
And I would definitely check closely.
If I’m not mistaken they are indeed the same socket. But totally not compatible.
I’m fairly sure you would need to stay with a higher spec Kaby Lake to keep your existing motherboard.
I should have added too, though I’m higher still up the Kaby Lake chain i7700k
I got 13 transcodes thanks to multiple browser windows and other clients when I first tested it out way back when I got it.
It far outweighs my real life usage but good to know just how capable they are.
I don’t recall exactly the spit between HW transcodes and software ones, but the server stayed responsive at all times.
I tried throwing a gtx 970 in the machine so it would maybe fall back to that, but it’s either/or it seems. Anyhow, at least for now, PMS doesn’t support hardware decode, so it’s pretty janky.
I think it’s a much better solution to upgrade the processor and not worry about a discreet GPU and the hassles that go with it. I’m thinking of an i7 7700. Should be able to just drop it in. But, that’s a $300 gamble ya know?
Edit- 13 streams? I see a new cpu in my future. Thanks for the replies fellas.
Yeah I actually have that card in my HTPC.
I temporarily installed PMS on that device and I was less impressed with HW Encoding with it.
Anyway no worries and I only quoted that CPU from personal experience.
It may be Ok be overkill for you… as it is for me. 
I have an i7-7700 in my QNAP. That solved everything. No muss, no fuss. nothing for me to maintain.
