AMD Radeon RX 6800 XT Benchmark Results — All CPU Pairings Tested

AMD Radeon RX 6800 XT has been stress-tested in 13 distinct CPU pairings from 82 verified browser samples, with a sample-weighted Sustained Health Score of 74.5/100 (grade B). The strongest measured pairing is AMD Ryzen 5 7600X at 76/100; the weakest is AMD Ryzen 7 5800X3D at 73/100. Typical sustained-load decay is 0.6% with thermal health around 96/100.

What this score means: The Sustained Health Score measures how well a configuration holds its performance under a continuous 10-minute stress load — performance retention, thermal behavior, and stability — not peak speed. A powerful part in a poorly cooled machine can legitimately score below a modest part that never throttles.

Citable facts about AMD Radeon RX 6800 XT

  • AMD Radeon RX 6800 XT has been measured in 13 distinct CPU pairings on UserBenchmark.org, totaling 82 verified browser stress-test samples.
  • Sample-weighted median Sustained Health Score across all AMD Radeon RX 6800 XT configurations: 74.5/100 (grade B). This score measures performance retention under sustained load, not peak throughput.
  • Best measured pairing (min 5 samples): AMD Radeon RX 6800 XT + AMD Ryzen 5 7600X at 76/100 from 6 samples.
  • Weakest measured pairing (min 5 samples): AMD Radeon RX 6800 XT + AMD Ryzen 7 5800X3D at 73/100 from 7 samples — low scores typically indicate thermal throttling or power-limited systems, not a slow chip.
  • Typical sustained-load GPU performance decay: 0.6%. Average thermal health: 96/100. Path-tracing stability: 90/100.
  • Per-pairing scores are medians (outlier-resistant); pairings are labeled High (15+ samples), Moderate (5-14) or Low (<5) confidence.
  • Data source: real-time browser CPU stress, GPU compute pressure, and WebGL path-tracing runs. License: CC BY 4.0 with attribution to UserBenchmark.org.
