My 7900X runs x265 very well, and it is still quite competitive, but it is an expensive platform unless you find good used parts. Were you were thinking of a 5960X or similar, the original 2011 socket? I have one of those too but x265 uses all the new stuff so older CPUs did not age well, the 5960X is only on par with a 2700X unless you overclock it. Both are decent but not spectacular.

Get a Skylake at the oldest, you don't really want older than that for x265.

oops i meant the lga 2011 socket like the e5 2690 and another thing i want to correct i compress all my walkthrough for channel at 720p 30fps im just wondering would upgrading be worth it because i use the medium preset and crf at 24

For only 720p x265 will max out at around 12 cores.
ok since you said 12 core i was thinking of ryzen 2 like the 2600 or 2700 or would it just been better to stick to intel because of avx 512

Core-for-core, modern Intel parts are faster in x265, but AMD has the edge dollar-for-dollar.

If thinking about it as a pure x265 encoding box the newest consumer 8 core without hyperthreading from Intel might beat out AMD in performance/dollar too, of course it would be slower for some other things, but x265 is very well optimized for Skylake-X and its newer derivatives.

But if that is too much money it gets a lot more complicated and you need to consider the entire build at the same time to really pick a value/dollar. I would probably go with a 2700X over anything slower than a 9700 but there is no way I would not wait for a Ryzen 3000. I REALLY want to see some Zen 2 x265 benchmarks... but what I want even more is to see them in a year, after the team has had more time to optimize for Zen 2.

I suspect a 16 core Zen 2 will be a very very fast x265 encoding box by the end of the year, but it is not available quite yet.

Is upload bandwidth expensive for you? I only ask because while CRF 24 is ok when you watch it, it is not very good after another reencode (which will happen). Upgrading to the slow preset at crf 21, hopefully not slower with a new CPU, could offer a big quality improvement for your viewers. Slow is a big improvement over medium by itself.

I have went back and forth between hardware and software 265 encoding. And I am happy with NVENC. I can legit do an encode in about 5-7 minutes (TV show recordings). With framerate around 150fps. It takes a heck of a cpu to get close to that.

It took me some playing with settings to get it where I like it. Also had to realize that QP values are different between x265 and NVENC H265. So comparing encodes with the same QP value between the two doesn't work.

I have an 1800x and 1050ti in my server. I really thought it would be better to use the CPU, but man even with the little 1050ti its just so fast. I stuck with HW.

its funny i was abput to ask about 2700x or the 5 2600 ryzen if they would be good and not i dont have issues with 24 because i have done it mutiple times and they look perfect to me and i understand what you mean im always looking at them afterwards and slow would take me like 3 days to encode if i did that some of my walkthroughs are like 11 hours long and i do rendering and video editing as well

nice and what gpu is that i understand it will take a while to tweak it to my liking and is it worth just getting a nevec h265 card and doing that way

For a NVenc card I suggest the 1660 as the cheapest option with the new improved encoder. They put an old one on the 1650.
