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.

NVIDIA's GTX 1660 follows hot on the heels of last month's release of the GTX 1660 Ti. As the name would suggest, the 1660 is a slightly scaled back version of the 1660 Ti. Both feature NVIDIAs's new TU116 Turing based die, have 6GB of VRAM, are without RTX cores and have a power draw (TDP) of 120W. The main differences arise from the number of CUDA cores: the 1660 has 1408 whilst the 1660 Ti has 1536, and memory bandwidth: the 1660 can deliver 8 Gpbs using ubiquitous GDDR5 (as featured in the GTX 1060 3GB and 6GB) versus the 1660 Ti which can deliver 12 Gpbs using newer, faster and dearer GDDR6. The 1660 also features Turing NVENC which is far more efficient than CPU encoding and alleviates the need for casual streamers to use a dedicated stream PC. Early benchmarks show that the GTX 1660 has about a 20% lower effective speed than the 1660 Ti, but with an entry price of $219 USD, the 1660 is also about 20% cheaper. Further, the 1660 has a 12% effective speed advantage over the ~$230 USD 6GB 1060 and a similar real world effective speed to AMD's $265 USD RX 590. NVIDIAs strategy of offering great value Turing products at all price tiers can only be good for competition and consumers. [Mar '19GPUPro]
