The Radeon RX Vega 64 is AMD’s latest Radeon flagship graphics card. It is the first Vega based gaming GPU and follows on from the recent launch of the Vega Frontier Edition. The Vega architecture is built on 14 nm silicon and contains next-generation compute units (nCUs) that have been engineered to be more efficient and powerful than ever before, enabling gamers to achieve higher frame rates at 4K. Each NCU houses 64 steam processors, of which the Vega 64 has 4096 (compared to 3584 in the Vega 56) which can process up to 13.7 TFLOPS (0.6 TFLOPS more than the Frontier Edition) in the liquid cooled version of the GPU. The new architecture also employs 8GB of second generation high-bandwidth memory (HBM2) which is able cope with more data, more quickly than previously. AMD describe this as the most significant leap in their GPU architecture for the last five years. Our graphics benchmarks place the performance of the Vega 64 amongst the best. Its effective speed is very close to that of the twice as expensive Frontier Edition (a workstation GPU with a gaming mode) and just behind NVIDIA’s similarly priced, but now 1 year old GTX 1080. Despite the hopes of AMD enthusiasts, the great performance from the Vega 64 has not been able to exceed the even greater performance from NVIDIA’s GTX 1080 Ti, released earlier this year. The 33% faster 1080 Ti offers better value for money than an RX 64 would even if it were available at its list price of $599. The best prices for RX 64's today are closer to $750 making the RX 64 somewhat redundant until prices drop down to the low $500 mark. ^{[Sep '17 GPUPro]}
