The RX 580 launched this week and is AMD’s latest flagship GPU which is based on a second generation Polaris architecture. The 580 is a refresh of the RX 480 which was released just 10 months ago. Modifications to the architecture have resulted in improved thermals and increased clock speeds by around 10%. The RX 580 will come with either 4GB or 8GB of high-bandwidth GDDR5 memory. Exact pricing for this mid-range chip remains to be seen, but the RX 500 series is likely to cannibalize sales of AMD’s 400 series. Performance wise, the RX 580 is in direct competition with NVIDIA’s popular GTX 1060 6GB which is now 9 months old. Perhaps after last year’s ill timed head to head release of the RX 480 and the faster but similarly priced GTX 1060 (a standoff which NVIDIA seem to have won based on market share), AMD are attempting to draw back some market share with the newer, slightly upgraded RX 580.

The widely anticipated (albeit currently not widely available) prosumer AMD Radeon VII is finally available. It features a next generation Vega 20 GPU which is based on a 7nm manufacturing process, compared to 14nm in the first generation flagship: the RX Vega 64. The Radeon VII has a massive 16GB of expensive high-bandwidth memory (HBM2) which offers a decent degree of future proofing and also makes it a good choice for memory hungry applications, however most current games do not require more than the 8GB that comes with both NVIDIA's RTX 2080 and AMD’s RX Vega 64. The Radeon VII has fewer cores than the RX Vega 64 (3840 vs 4096) but clock speeds have been boosted up to 1800 MHz compared to 1546 MHz in the RX Vega 64, the net result is 13.8 TFLOPS single precision computations (versus 13.4 TFLOPS for the RX Vega 64). On the negative side, the Radeon VII is designed with three cooling fans which can get noisy and early software drivers are reported to be buggy. Whilst there is a modest 16% performance advantage over the RX Vega 64, initial benchmarks indicate that the Radeon VII has an effective speed which is 6% short of the similarly priced RTX 2080.
