Preliminary look at 5700/XT by Wendell and EposVox for streaming/content creation (it's buggy, but promising):
Some highlights:
1) OBS w/AMF plugin is kinda broken right now, need clean install of new version of plugin
2) FFMPEG basically broken for now (looks like trash)
3) Hardware AMF encoder is equivalent to x.264 Fast, which is an improvement over previous generations including Radeon VII
4) HEVC encoding is "mind-blowing" - doing 5 or 6 FFMPEG encodes
at once
5) The new CAS feature (Content Adaptive Sharpening, 1440p upscaling to 4K) is very good without noticeable blurring or over-sharpening - may be a viable option for playing on 4K HDTVs while getting 1440p performance
6) Radeon Anti-Lag is different from Fast Sync - they used high speed camera setup to capture the difference. Best case scenario vs nV (for nV): AMD is 7ms ahead / Worst case: AMD is 16-17ms ahead (!)
So for competitive gaming/e-sports titles, Anti-Lag can actually offer a surprisingly big difference
. Of note: there probably isn't anything that would stop nV from making a similar feature
