Test Configuration – Software
–Nvidia’s GeForce 388.09 GTX 1070 Ti launch drivers were used for all NVIDIA cards – except for benching Wolfenstein: The New Order with –GeForce 388.13. High Quality, prefer maximum performance, single display.
–AMD ReLive Crimson Software 17.10.3 drivers were used for benching the RX Vega 64 LC except for 17.10.1 used for Ashes of the Singularity which would not launch in DX12 otherwise.
–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.
–Highest quality sound (stereo) used in all games.
–Windows 10 64-bit Home edition. All DX11 titles were run under DX11 render paths, ten DX12 titles are run under the DX12 render path, and two Games use the Vulkan API
–All games are patched to their latest versions at time of publication.
–Crimson Software’s WattMan was used for the RX Vega 64 LC.
–MSI’s Afterburner, latest beta used for NVIDIA cards.
–OCAT, latest version
–Fraps, latest version

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 graphics settings in AMD’s Crimson ReLive control panel that we use. We used WattMan to set the Power, fan, and temperature 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 ReLive 17.10.3 drivers, WattMan occasionally does not always hold its settings between reboots, so it’s important to check and reset each overclock as needed. However, we have noted that the latest drivers brings some very welcomed added stability to overclocking although Ashes of the Singularity would not launch in DX12, and its Escalation expansion would not launch in Vulkan.
There are two methods of calculating percentages. In a recent 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 the stock and the overclocked GTX 1070 Ti results.
For the percentage changes, we mean the increase in frame rates between the stock GTX 1070 Ti results and the overclocked results, 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 check out overclocking and noise.
