AMD Radeon(TM) 660M Benchmark Results — All CPU Pairings Tested

AMD Radeon(TM) 660M has been stress-tested in 2 distinct CPU pairings from 12 verified browser samples, with a sample-weighted Sustained Health Score of 63.7/100 (grade C). The strongest measured pairing is Ryzen 5 6600U at 64/100; the weakest is AMD Ryzen 5 7500F at 63/100. Typical sustained-load decay is 0% with thermal health around 97/100.

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(TM) 660M

AMD Radeon(TM) 660M has been measured in 2 distinct CPU pairings on UserBenchmark.org, totaling 12 verified browser stress-test samples.
Sample-weighted median Sustained Health Score across all AMD Radeon(TM) 660M configurations: 63.7/100 (grade C). This score measures performance retention under sustained load, not peak throughput.
Best measured pairing (min 5 samples): AMD Radeon(TM) 660M + Ryzen 5 6600U at 64/100 from 8 samples.
Weakest measured pairing (min 5 samples): AMD Radeon(TM) 660M + AMD Ryzen 5 7500F at 63/100 from 4 samples — low scores typically indicate thermal throttling or power-limited systems, not a slow chip.
Typical sustained-load GPU performance decay: 0%. Average thermal health: 97/100. Path-tracing stability: 91/100.
Per-pairing scores are medians (outlier-resistant); pairings are labeled High (15+ samples), Moderate (5-14) or Low (<5) confidence.
