Test Configuration – Software
- GeForce WHQL 384.94 was used for the GTX 1080 at stock and WHQL 385.41 for overclocked settings. WHQL 385.28 was used for the GTX 1080 Ti. High Quality, prefer maximum performance, single display. See control panel images below.
- AMD ReLive Software RX Vega public launch drivers (17.30.1051-b6) were used for the benching the Vega 64 at stock clocks and 17.8.2 was used for the overclocked results. See control panel image below.
- VSync is off in the control panel.
- AA enabled as noted in games; all in-game settings are specified with 16xAF always applied
- All results show average frame rates including minimum frame rates shown in italics on the chart next to the averages in smaller font. Percentage increases are calculated between the average frame rates of the RX Vega 64 at stock and at overclocked settings, and also of the GTX 1080 between stock and overclocked settings.
- Highest quality sound (stereo) used in all games.
- Windows 10 64-bit Home edition, all DX11 titles were run under DX11 render paths. Our four DX12 titles are run under the DX12 render path. Latest DirectX
- All games are patched to their latest versions at time of publication.
- MSI Afterburner.

Nvidia Control Panel settings
We used MSI’s Afterburner to set the power and temp limits to their maximums.
AMD Radeon Global Settings:
Here are the global game settings in AMD’s ReLive control panel that we use. We used WattMan to set the Power and temp limits to their maximums.
Using WattMan for our regular non-overclocked settings, the Power Limit is set to +50%, the temperature is allowed to reach the maximum 70C, and the fan is also allowed to spin up to its maximum, but the core and memory clocks are unchanged.
Even with the latest Crimson 17.8.2 drivers, WattMan does not always hold its settings between reboots, so it’s important to check and reset your overclock as needed.
There are two methods of calculating percentages. In our last evaluation we used “Performance Differences” to compare the GTX 1080 and the GTX 1080 Ti versus the RX Vega 64 LC. This time we are now using “Percentage Changes” which are usually used to show improvements in average frame rates (FPS) between stock and overclocked results.
For the percentage changes, we mean the increase in frame rates between the stock and the overclocked RX Vega 64 (and stock and overclocked GTX 1080), divided by the absolute value of the original stock frame rate in FPS, multiplied by 100. Percentage change may be expressed by the algebraic formula where “V” is Value: ( ΔV / |V1| ) * 100 = ((V2 – V1) / |V1|) * 100
We also made a BTR community forum post that explains the process of calculating percentage differences using frame rates as an example.
Let’s head to the performance charts to see how the overclocked-to-the-max GTX 1080 FE compares with the overclocked-to-the-max Gigabyte RX Vega 64 Liquid edition.
