Fixing Rasterization Score for Tiling GPU Architectures
‍

Evolve is a high-performance benchmark designed to measure the capabilities of modern graphics hardware across desktop and mobile devices.

On most graphics cards, this measurement is straightforward: for each draw call (a request to render geometry on screen) Evolve is able to time this operation precisely. Most mobile chips, however, operate fundamentally differently. To maximize battery life and minimize heat generation, mobile GPUs don't render the entire screen at once. Instead, they divide the screen into small rectangular sections called "tiles" and process each tile using fast tile memory. This tiling architecture is exceptionally power-efficient, but it fundamentally changes how rendering work is organized.

When Evolve requested timing information on a tiling GPU, it didn't receive accurate data. The timestamps only captured a small fraction of the actual work, causing some devices to report artificially inflated scores, up to 10 times higher than their true performance.

Our solution is to measure the entire rendering phase as one cohesive unit of work, the complete render pass. By measuring the render pass in aggregate all GPU architectures are handled consistently and can report reliably. Unfortunately, as a result, our rasterization scores on affected mobile devices will decrease by approximately 10x to reflect actual performance, while desktop scores will see a minor 2-4% reduction due to more comprehensive measurement. Thankfully this correction ensures Evolve provides accurate, comparable performance metrics across all device types.
