Test Configuration – Software
- GeForce WHQL 384.94 was used for the GTX 1080 and WHQL 385.28 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. 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 differences are calculated between the average frame rates of the RX Vega 64 and of the GTX 1080 and GTX 1080 Ti.

Nvidia Control Panel settings:
These are the setting we use when testing NVIDIA cards.
AMD Radeon Global Settings:
Here are the global game settings in AMD’s ReLive control panel that we use:
These are the custom gaming global settings that we used for our RX Vega 64 that gave us slightly better performance than using the “Turbo” Preset. 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.
Here are the results of using the regular BIOS when running Heaven 3.0:
Here are the performance BIOS results of running Heaven 3.0:There is only about 1%-2% performance difference that we measured between the regular BIOS and the performance BIOS depending on the game or benchmark we used. And we use the performance BIOS setting for all of our RX Vega 64 benchmarking.
The above is our test bench and the settings that we used. Now let’s see how we calculate percentage differences between the RX Vega 64 and the GTX 1080 and GTX 1080 Ti.
There are two methods of calculating percentages. This one we are now using is the “Percentage Difference” that we are using to compare the GTX 1080 and the GTX 1080 Ti versus the RX Vega 64 LC, and the other is “Percentage Change” which are usually used to show improvements. Percentage difference is generally used when you want to know the difference in percentage between two values, in this case the difference in average frame rates (FPS) between RX Vega 64 and the GTXes 1080/Ti.
For the percentage difference we are simply dividing the difference between two numbers by the average of the two numbers. This is usually expressed algebraically where “V” equals value: ( | V1 – V2 | / ((V1 + V2)/2) ) * 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 our Performance Summary chart followed by our conclusion.
