AMD Kaveri Update: A10-7800 APU Review
GPU Testing: 3DMark Fire Strike
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. Normal mode is what we used for these tests.

The more taxing Extreme mode, which we use for high-end graphics testing, 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. We obviously ran the less-taxing standard test here.
There's no comparison here. AMD's latest Kaveri-based APU has no trouble dispatching all of the other processors tested, once again thanks to its more powerful Radeon R7 GPU configuration.
