Test Setup And Benchmarks
I ran the benchmarks on the following page for AMD Radeon R7 260 Review: The Bonaire GPU Rides Again, where I went into depth on average frame rates and frame time variance. For the sake of brevity, I'm emphasizing frame rates this time around. If you want deeper analysis, we invite you to check out the Radeon R7 260 launch story.
What we're adding to the mix are screenshot to show how the detail settings we're choosing actually look at 1920x1080. My intention there is to show that dialing back image quality doesn't necessarily mean AMD's Radeon HD 7770/R7 250X is forced down to ugly levels of game play.

We've almost completely eliminated mechanical storage in the lab, and instead lean on solid-state drives to alleviate I/O-related bottlenecks. Samsung sent all of our offices 256 GB 840 Pros, so we standardize on these exceptional SSDs.
Naturally, discrete graphics cards require a substantial amount of stable power, so XFX sent along its PRO850W 80 PLUS Bronze-certified power supply. This modular PSU employs a single +12 V rail rated for 70 A. XFX claims that this unit provides 850 W of continuous power (not peak) at 50 degrees Celsius (a higher temperature than you'll find inside most enclosures).
