Experience Based Performance Testing
For our RX Vega pre-briefing, AMD took an interesting turn on talking about performance metrics and comparisons to the competition. Rather than showing average frame rates in comparison the GTX 1080 or even 99th percentile frame time data that we have come to expect from the new guys helping to run the product and marketing teams, instead we are getting performance comparison based on FreeSync ranges and 99th % minimum frame rates.
The idea is this: for a gamer that buys an RX Vega they should be concerned about getting a smooth gaming experience. AMD showed data from two high-end resolutions, 3440x1440 and 4K, both with variable refresh windows based on the associated FreeSync display.
Based on this slide, AMD is telling us that the GeForce GTX 1080 has 99th % minimum frame rate in the range of 45 to 78 FPS in a range of titles including Ashes, BF1, Hitman, and more. At the same settings, the Radeon RX Vega 64 has a 99th % minimum frame rates in the range of 53 to 76 FPS. Based on AMD’s testing, the GTX 1080 dips lower in some of these games than the RX Vega 64. If you are using a display with a 48-100 Hz variable refresh rate, going below 48 FPS means you are outside the VRR range (which to be clear, is only true on FreeSync monitors, not G-Sync) and that equates to a “poor” gaming experience.
As you look at the numbers for that, AMD is pointing out that the GTX 1080 has a good experience in five of the six games, while the RX Vega 64 has a good experience in all six.
Looking at the same testing process for 4K, with a FreeSync display range of 40-60 Hz, we can again see the ranges that AMD measures.
So AMD Benchmarking is looking at a different point of view. Rather than AVG FPS they looking at the performance you should get from a Freesync Range to keep the Frame Rate smooth.
My big issue here is I only want the Watercooled Version but Price is a bit worry for me atm. Min FPS for me isn't really an issue has I the type of gamer that will happy game at High settings.
