The QP value of 26 is the main thing you would want to mess with to see where you like it. And it can vary based on the source on how much compression you get.
thanks for the info

When I'm at my desk I will post them. There isn't a lot of settings available for NVENC compared to software. But it's good enough.

Do note that I am encoding 1080i mpeg cable recordings. So they are already pretty compressed and not the greatest quality.

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.

If you have a dedicated server or a farm, sure using x265 is doable, otherwise not really. With HWenc it is order of magnitude faster while quality/size is still pretty good when set right.
If you do post processing you will need a GPU with enough shaders to keep up. Not all videos are good for transcoding so you will often need to post process to get better quality encode especially at low bitrates.
NVenc also tends to be finicky with colors.

There are trade offs and traps no matter what you use.

Good encoding tools that use NVenc especially HEVC and actually work... the jury is still out. Plus what decoder do you use to read and decode video for encoder to transcode also plays a role in speed.

The table linked above is a good guide to the hardware but software support and availability is equally important. AMD had HWenc for quite some time but the software support sucked.

Handbrake is sort of a "bloatfree" free variant of all the spammed video converters you can often see floating around and ads for. Aimed at easy click done use.
If you want more control, cutting edge support, change parameters etc. you're probably gonna run away from Handbrake. Or test performance and find out it's slow.

The software should be better nowadays and support for Turing finally added to most.

If you want best quality then x264 is king not x265. HEVC is better at lower bitrates = lower quality encodes but not at high bitrate encodes.

i use handbrake or ffmpeg sometime so that another can of worms and i dont have a encoder farm lol unless i have a bucket full of money lol i use h265 for achives of my game walkthroughs just in case of my channel gets taken down or if i have render them with muted music and even with recording i use a elgato so it not the best for old school consoles ha

In my non scientific testing comparing a 1050ti to a 2060, just measuring FPS using the same profile in Handbrake I saw no increase in performance. But I know things may be going on in the background that took further load off of the cpu.

also just a question if i wanted to get a cheap gtx 10 series card for h265 what would be the cheapest
The ryzen would be great and a new platform may be the better option. But its all about time. Software x265 vs HW h265 are too different animals when it comes to speed. If time is not a huge concern the Ryzen will do fine.

A poster said above that they left the old encoder/decoder in the 1650. So sounds like if you want the new h265 chip you need a 1660. Although I get along just fine with a 1050ti. And when I had a 2060 I can't say I noticed much difference. Not sure if this has been posted but here is the difference between the cards.

You could up the performance a tiny bit by obtaining a 1660 Ti .
