MojoKid writes: AMD has finally launched its Radeon RX Vega series of graphics cards today, based on the company's next generation Vega 10 GPU architecture. There are three base card specs announced, though there are four cards total, with a Limited Edition air-cooled card as well. Three of the cards have 64 NGCs (Next Generation Compute Units) with 4096 stream processors, while Radeon RX Vega 56 is comprised of 56 NCGs with 3584 SPs. Base clocks range from roughly 1150 to 1400MHz, with boost clocks from 1470MHz to 1670MHz or so. All cards come with 8GB of HBM2 and sport 484GB/sec of memory bandwidth, except for Vega 56, which has a bit less, at 410GB/s. They are power-hungry as well, ranging from the 345 Watt liquid-cooled Radeon RX Vega 64, to the 295 Watt air-cooled RX Vega 64 and 210 Watt Radeon RX Vega 56. Performance-wise, Radeon RX Vega 64 is neck-and-neck with NVIDIA's GeForce GTX 1080, winning some and losing some, with flashes of strength in DirectX 12-based games and benchmarks. Vega 64 also maintains generally better minimum frame rates versus GTX 1080. Radeon RX Vega 56 is a more credible midrange threat that handily out-performs a GeForce GTX 1070 across the board. In DX12 gaming, Radeon RX Vega 56 stretches its lead over the similarly-priced GTX 1070. Both cards, however, are more power-hungry, louder and run hotter than NVIDIA's high-end GeForce GTX 1080. Radeon RX Vega 64 cards will retail for $499 (Liquid Cooled cards at $699), while Radeon RX Vega 56 drops in at $399. All cards should be available at retail starting today.
