It is no rocket science that workstation cards are rarely great miners. The price of the card does not help either. Some users speculate that the mining performance of the card might improve after AMD releases new drivers. While that makes a lot of sense, the real question is how much improvement can we expect? Personally I won’t jump into conclusions just yet.
AMD's Radeon Vega Frontier Edition performs well in targeted professional applications thanks to support for Radeon Pro certified drivers. However, it isn't as fast as many prosumers might have hoped in games. While it's possible that a forthcoming software update improves performance, the already-announced Radeon RX Vega 64 should be comparable (and less expensive) for gaming-only.
Looking again at Vega: FE and ignoring RX Vega, keep in mind that there are still plenty of kinks to work out of the drivers. WattMan is buggy right now, with overclocking at least partly broken, fan speed control somewhat delayed/buggy, and occasional colored screen hangs (like AMD fixed after the last time we reported them). Vega: FE has room to improve in at least these ways, if not in something more nebulous – like gaming.
For some users, the AMD Radeon Vega Frontier Edition graphics hardware represents a professional level of performance at a lower price that utilizes the AMD software ecosystem. For others, it is simply a bellwether for the coming Radeon Vega consumer graphics cards. For the gamers out there, reading this and hoping to be uplifted and excited about the RX Vega product, it’s a tough sell, no getting around that.
