Ryzen 5 8645HS Benchmark Results — All GPU Pairings Tested
Ryzen 5 8645HS has been stress-tested in 3 distinct GPU pairings from 22 verified browser samples, with a sample-weighted Sustained Health Score of 63.4/100 (grade C). The strongest measured pairing is NVIDIA GeForce RTX 4050 Laptop GPU at 74/100; the weakest is AMD Radeon 760M at 57.5/100. Typical sustained-load decay is 0.2% with thermal health around 90/100.
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.

Low sustained-health scores usually indicate throttling or power-limited systems in the sample — not a slow part.
Full combo analysisCitable facts about Ryzen 5 8645HS
- Ryzen 5 8645HS has been measured in 3 distinct GPU pairings on UserBenchmark.org, totaling 22 verified browser stress-test samples.
- Sample-weighted median Sustained Health Score across all Ryzen 5 8645HS configurations: 63.4/100 (grade C). This score measures performance retention under sustained load, not peak throughput.
- Best measured pairing (min 5 samples): Ryzen 5 8645HS + NVIDIA GeForce RTX 4050 Laptop GPU at 74/100 from 6 samples.
- Weakest measured pairing (min 5 samples): Ryzen 5 8645HS + AMD Radeon 760M at 57.5/100 from 13 samples — low scores typically indicate thermal throttling or power-limited systems, not a slow chip.
- Typical sustained-load CPU performance decay: 0.2%. Average thermal health: 90/100. Path-tracing stability: 86/100.
- Per-pairing scores are medians (outlier-resistant); pairings are labeled High (15+ samples), Moderate (5-14) or Low (<5) confidence.
