Yes, I see all of the charts swapped -- SandyBridge on top. :shrug: I'm more interested in all the remaining pages. I hope your time frees up.
I've been using Ryzen for video editing, and I've noticed two things.
First, the lack of quicksync really hampers decode acceleration, to the point where a 7700k may well be a better bet for some users. Single-threaded UHD avc decode in my NLE can't complete at 60p, so unless the video is packaged with multiple slices (two might work at ~4.1G, but I'm only stable at 3.9), I'm not real-time in my software. That's a problem. Fortunately I have quad-slice cam output, so I'm fine for now, and can only hope that the software eventually makes use of nvdec (or some upgraded amd equivalent).
Worse (and second), if the decode threads, which are long-pole items, wind up having their time stolen by SMT'd threads, I'm in for a bad time. There are very strange performance pits. I can put a few cams-worth of video in a loop, and one time through the loop everything is good, and another time through it, we're hiccoughing like crazy. This usually happens when the processor is nearly fully utilized (over 80%). I haven't re-run that test after I upgraded my BIOS (to F5g on a Gaming 5, which is supposed to have 1.0.0.4), so maybe things have improved, but it feels like some kind of scheduling problem. If the threads are scheduled on top of each other (err, same core), they seem to stay that way until the next go-around. :shrug: [This is Win7, btw]
Hopefully those observations are useful in some way. Obviously more investigation would be required. A longer, video-editing-focused review which I would sum up with "not all things parallelizable are parallelized" is here
https://www.pugetsystems.com/labs/a...2017-AMD-Ryzen-7-1700X-1800X-Performance-909/. As someone who wants to know why their benchmarks look a certain way, this kind of article will likely grate, but the kind of software behavior it demonstrates is going to be a problem for some HEDT targets. That said, I'd be lying if I claimed I wasn't interested in a 16 core anyway.
Thanks for the time!
