help with a upgrade h.265

hi everyone im just asking does anymore use handbrake h265 encoding with handbrake im looking to either speed up the encoding time for 4k videos thay are taking a long time im using i7 2600k and r9 380

I am pretty familiar with Handbrake and use standalone x265 a lot.

Software encoding is also not the only option. An Nvidia 1660 has a new hardware H.265 encoder that is decent quality and very fast. I am a big fan of x265's software encoding, and it still offers better quality, but you really have to pay for it with CPU cycles. Now there is a hardware option with acceptable quality and it is really fast at the same time. I don't use it myself, I do mostly archival video, but I am not sure what your use case is.

If you are seeking hardware advice, do you have a budget? x265 likes cores, up to a point, but that point is a lot with 4K video. A 12 or 16 core Ryzen 3000 will likely perform very well at a great price, though x265 uses AVX2 and AVX512 enough that performance for those is important too, we need to wait for benchmarks to be sure. As many very fast cores as possible is best, though above ~32 cores (64 threads) is probably overkill.

i was wondering about the new amd cpus they look awesome but i will have to see how much they will be in australia but my budget is 1200 dollars and yeah i like to compress my 4k 60fps walkthrough for archives

also im still learning does cpu or gpu matter more for h265 encoding

Only the CPU matters, the GPU is not used at all.

There have been some GPU stuff done for software encoders in the past but it never helped much and it sometimes hurt quality. Nothing in Handbrake will use the GPU or even notice which one you have installed.

Edit:
This list is probably very accurate for which CPU for your budget. 4K will simply scale better with more cores.

ok i know this sounds dumb is there a limt to how many cores handbrake can handle because i was reading that handbrake can only handle 6 cores

Handbrake is just a front-end and the underlying encoders it uses will support a lot of cores.

The i9-9900K looks like a pretty good deal on that list, a bargain compared to anything near it.

The i7-9700K looks like the best price/performance option. AMD's current CPUs are not a good choice for AVX2 & AVX512 enabled workflows so are not a great option for x265. I expect their new 7nm CPUs to be better we don't know how much yet.

I have seen people running x265 on 56 core systems (2 socket 28 core CPUs). You cannot saturate all the cores with just one encode but you can get close, and x265 will happily run on them all. Running x265 via Handbrake will not change how many cores it can utilize.

wow thats a lot of core for sure and i was thinking of the 10 core 20 threads cpu for the lga 2011 socket i knows it older hardware but i think i have my mind set on ryzen 3 or intel im not trying to start a flame war
