Reviews of AMD’s new Vega GPUs are starting to become available from reputable sources, and early mining test results don’t look great. Tom’s Hardware posted a first look of a Radeon RX 64 Vega (8GB) card yesterday, and only managed to hit 30.9 MH/sec on the latest version of Claymore’s miner. That’s comparable to performance of BIOS-optimized RX 4xx/5xx cards, and they draw considerably less power.

Keep in mind that these are out-of-the-box results, and no doubt higher speeds will be achieved once miners are able to experiment with clock speed and BIOS settings. But even if modders are eventually able to coax 40 MH/sec from Vega GPUs, they’ll probably never be a top-tier choice for miners, given their power consumption and high up-front cost ($599+ MSRP, although they’re currently selling for over $1,000 on Amazon).
