The new AMD R9 390 is the direct successor to the R9 290. Both cards share the same GPU but the R9 390 is factory overclocked. The R9 390 has a 5% higher stock GPU clock, and a substantial stock memory clock increase of 20%. Additionally the R9 390 sports a minimum of 8GB of VRAM versus 4GB on the R9 290. At the current price levels of $329, the R9 390 can't compete given that R9 290s can be had for around $260. The increased VRAM will rarely help even at ultra high resolutions and in any case, most 4K gamers are likely to seek more GPU power than the R9 390 has to offer. We have seen several samples of the R9 390 and they scored an effective speed of 88.5% which, as expected, matches the speeds seen on overclocked R9 290s. On the face of it purchasing an R9 290 at a discount and then manually overclocking will result in the same performance as an R9 390 but with a saving of around $70. [Jun '15GPUPro]
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.
