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.

Calculating Percentages

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.


  1. Dear PCmasterRACE, https://uploads.disquscdn.com/images/a52063dad5eee3042abd5c3f7dc105343dc4c19f2b386a679f6882b494a8f994.jpg
    Omg so disappointed!!! I guess it’s really Navi + InfinityFabric that AMD is really heavily investing it’s R&D on. Perhaps they plan on combining 2x Rx580 on a single die in order to create a near 1080 Ti level performance card and sell at a cheaper price like the Ryzen ThreadRipper. ? Wadda ya guys think? And thank you so much for the wonderfully detailed review btw, God Bless!

    Best Regards,

  2. Why do reviewers never factor in that high-end g-sync displays cost several hundred dollars more than their freesync counterparts? In my case it’s a $300 increase for an identical g-sync counterpart. The $699 vega 64 liquid card gives me better price for performance than both the 1080 and 1080ti because of the g-sync tax, albeit lame the +$100 bill for the stupid “free” games. Folks who jumped on the $200 off a freesync ultrawide with vega bundle certainly got a great deal, assuming they wanted the monitor upgrade.

    I look forward toy our VR performance review.

    • Thanks for that clarification. I updated my conclusion:

      “However, the $699 RX Vega 64 Liquid Edition only trades blows with a $499 GTX 1080 (Updated note: the Founders Edition is $549) . . . “

  3. The FE cards have the worst performance per dollar at stock. Is it possible to include an overclocked column in the results?

  4. The way I see it, Vega is a much better choice moving forward.

    AMD also has better support in games now, things have changed. I see why RX Vega cost a premium, because it offers the latest technology. Just can’t find any to buy at MSRP.
