3DMark Fire Strike Test

3DMark Fire Strike has two benchmark modes: Normal mode runs at 1920x1080, while Extreme mode targets 2560x1440. GPU target frame buffer utilization for normal mode is 1GB and the benchmark uses tessellation, ambient occlusion, volume illumination, and a medium-quality depth of field filter. The more taxing Extreme mode targets 1.5GB of frame buffer memory and increases detail levels across the board. Extreme mode is explicitly designed for CrossFire / SLI systems. GT 1 focuses on geometry and illumination, with over 100 shadow casting spot lights, 140 non-shadow casting point lights, and 3.9 million vertices calculated for tessellation per frame. And 80 million pixels are processed per frame. GT2 emphasizes particles and GPU simulations. Tessellation volume is reduced to 2.6 million vertices and the number of pixels processed per frame rises to 170 million.

The Radeon R9 390's additional memory and higher memory bandwidth give it an edge over the Radeon R9 290X in the overall score, but as you can see, it actually trails the 290X in GT1. The 390 wins, however, in GT2, which is what pushes it ahead overall.
