The AMD RX Vega 56 and 64 graphics cards launched today. Most of the online retailers in the US who had them in stock are already sold out. All the initial reviews seem to show they are good competition for the GTX 1070 and GTX 1080. The game benchmark results show that some games they do better than the GCX 1070 and GTX 1080 while in other games they do worse than the GXT 1070 and GTX 1080. Overall they seem to equally well when you look at the popular games from the past 2 years. However, the RX Vega cards use significantly more power and they have a locked BIOS that doesn't allow the max power levels to be increased even though the VRM can handle more power. Also some reviews state the RX Vega runs significantly hotter than the GTX 1070 and GTX 1080 FOunders edition cards, which have some of the worst cooling for their series. Anandtech's review said: "The Vega 10 is a large, power-hungry GPU. Much larger and much more power hungry than NVIDIA’s competing GP104 GPU. And while this isn’t an immediate consumer concern – we pay what the market will bear, not what it costs AMD to make a chip with a nice gross margin on the side – from a technology and architectural perspective it indicates that AMD has moved farther away from NVIDIA in the last couple of years. Whereas the Radeon R9 Fury X was almost a win that AMD didn’t get, the RX Vega 64 doesn’t appear to be fighting in the weight class it was even designed for. Instead the power efficiency gap between AMD and NVIDIA has grown since 2015, and apparently by quite a bit." Overall, I'm happy to see AMD making a competitive GPU again. Maybe some of the custom PCB cards form other manufacturers will allow a custom BIOS or have a BIOS with a higher power level to have room for better overclocking.
