Benchmark performance

Non-gaming benchmark performance of Radeon X850 PRO. Note that overall benchmark performance is measured in points in 0-100 range.

  • Passmark


This is probably the most ubiquitous benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.
