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.
General Test System 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.

Our test system consists of an overclocked Core i7-7700K processor and 16GB of 3200MHz Geil DDR4. High-end hardware is used to eliminate CPU and memory from the bottleneck equation and put the performance onus solely on the GPU being tested.

With the shortage of GDDR5X, I’m wondering if the GTX 1080 is being phased out, because this is (95% of) a GTX 1080 GDDR5. Maybe the endgame is for the 1080 to be discontinued, the GP104s going into 1070 Ti instead, and the GDDR5X to be saved for the 1080 Ti and possibly mid-range Volta cards if the early flagships use GDDR6?
