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.

The GeForce GTX 1070 Ti is Nvidia’s latest HD and VR ready, gaming GPU and is successor to the current number one GPU by market share, the GTX 1070. Like the 1070, the 1070 Ti is based on the16nm Pascal architecture and GP104 GPU. Both feature 8 GB of GDDR5 memory with a 256 bit memory interface producing a total memory bandwidth of 256 GB/s, and both have a rated boost clock speed of 1.683 GHz. The 1070 Ti is basically the 1070 with 25% more working CUDA cores (2432 versus 1920) and slightly higher base clock of 1607MHz (versus 1506MHz in the 1070). This translates to the 1070 Ti being nearly as powerful as the GTX 1080 which has 2560 CUDA cores, 8 GB of GDRR5X memory and boost clock of 1733 GHz. With founder’s editions available at $449, compared to $470 for AMD’s recent Vega based RX 56 and $510 for the GTX 1080, the 1070 Ti represents good value for money. The rumored fast approaching release of Volta (NVIDIA’s next generation architecture following on from Pascal) in early 2018 may upset demand for the 1070 Ti. [Nov '17GPUPro]
