Hyped as the "Ultimate GeForce", the 1080 Ti is NVIDIA's latest flagship 4K VR ready GPU. It supersedes last years GTX 1080, offering a 20% increase in performance for a 40% premium (founders edition 1080 Tis will be priced at $699, pushing down the price of the 1080 to $499). It also supersedes the prohibitively expensive Titan X Pascal, pushing it off poll position in performance rankings. The 1080 Ti is based on the Pascal architecture and features a slightly modified version of the same flagship GP102 silicon found in the Titan X Pascal. It has 11GB of the high bandwidth GDDR5X video memory (versus 12GB in the Titan X Pascal) and an impressive 11GB frame buffer. Like the Titan X Pascal, it features 12bn transistors and 3584 CUDA cores which can run at a boost clock speed of 1.582 GHz – 3% faster than the Titan X Pascal's 1.531 GHz. This increased speed is partially attributable to the 1080 Ti’s new dualFET power system which allows the chip to run at higher power and more efficiently than ever before. The release of the 1080 Ti comes ahead of the competition from AMD's Vega - rumored for release in Q2 2017. Vega is AMD's next generation graphics card (following on from Polaris 10) featuring their new HBM2 die which is alleged to have eight times the capacity of GDDR5 with half of the footprint. NVDIA's own next generation graphics cards (Volta) are in the pipeline for 2018. [Mar '17GPUPro]
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.
