Windows 10, beta (closed) drivers. Probably it throttles, add "-tt 50" option to "config.txt".
UPDATE: my bad, I really see 310H/s in Windows 7 + public drivers. So it is either drivers, or Windows version, I will check it right now.
UPDATE2: it is drivers. If I use public drivers, I can get only 310-320H/s. For beta drivers, I get 440-450H/s. AMD should release new version of drivers asap, current public drivers are bad.

Thanks for the very useful info.

AMD Radeon Vega Frontier Edition (Air)
OS = Windows 7 Professional SP1
Driver = Radeon Vega Frontier Edition 17.6
Average Solutions per Second = 310 (throttles if you let it run for 10+ minutes)

AMD Radeon Vega Frontier Edition(Liquid) / RYZEN 7 1800X or Core i7-7700K
Will try later tonight with Windows 10 Professional or Ubuntu 16.04.3 LTS with beta drivers and report back

I was not able to make Vega work in Ubuntu: gpu-pro drivers for Vega don't install OpenCL for some reason and my miner does not support ROCm. Though I could miss something because I'm not Linux guru.

440H/s is worse than a Fiji, isn't it weird?

It is about the same hashrate as Fury Nano. Yeah it is weird, but you can see that AMD has really bad drivers for Vega currently, I think they will improve it in the future.

RX460/560 cards (+20% speed)?Any tests?

In my tests 107H/s -> 130H/s on stock RX460 2GB.
