Fire Strike has two benchmark modes: Standard mode runs in 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. Only 80 million pixels are processed per frame. GT2 emphasizes particles and GPU simulations. Tessellation volume is reduced to 2.6 million vertices, but the number of pixels processed per frame rises to 170 million. |
The 3DMark Fire Strike benchmark tells essentially the same story as Unigine Heaven from the previous page. The new Radeon HD 7790 cards outpace the Radeon HD 7770, as expected, and pull ahead of the GeForce GTX 650 as well. The Radeon HD 7850 and GeForce GTX 660, however, offered significantly better performance.
