Sapphire RX Vega 64 Nitro+ Limited Edition – better than GTX1080?

Our newest GPU test procedure has been built with the intention of benchmarking high-end graphics cards. We test at 1920×1080 (1080p), 2560×1440 (1440p), and 3840×2160 (4K UHD) resolutions.

We try to test using the DX12 API if titles offer support. This gives us an interpretation into the graphics card performance hierarchy in the present time and the near future, when DX12 becomes more prevalent. After all, graphics cards of this expense may stay in a gamer’s system for a number of product generations/years before being upgraded.

We tested the RX Vega64 and Vega56 using the ‘Turbo‘ power mode in AMD’s WattMan software. This prioritises all-out performance over power efficiency, noise output, and lower thermals.

Driver Notes

  • AMD Graphics cards were benchmarked with the AMD Crimson ReLive 17.9.1 driver.
  • Nvidia Graphics cards, not including GTX 1070 Ti cards, were benchmarked with the Nvidia 384.94 driver.
  • GTX 1070 Ti cards were benchmarked with the Nvidia 388.09 driver.
