NVIDIA GeForce RTX 4090 Benchmark Results — All CPU Pairings Tested
NVIDIA GeForce RTX 4090 has been stress-tested in 16 distinct CPU pairings from 192 verified browser samples, with a sample-weighted Sustained Health Score of 79/100 (grade B). The strongest measured pairing is AMD Ryzen 9 7950X at 81.5/100; the weakest is Intel Core i9-13900KF at 76.5/100. Typical sustained-load decay is 0.9% 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.

Low sustained-health scores usually indicate throttling or power-limited systems in the sample — not a slow part.
Full combo analysisCitable facts about NVIDIA GeForce RTX 4090
- NVIDIA GeForce RTX 4090 has been measured in 16 distinct CPU pairings on UserBenchmark.org, totaling 192 verified browser stress-test samples.
- Sample-weighted median Sustained Health Score across all NVIDIA GeForce RTX 4090 configurations: 79/100 (grade B). This score measures performance retention under sustained load, not peak throughput.
- Best measured pairing (min 5 samples): NVIDIA GeForce RTX 4090 + AMD Ryzen 9 7950X at 81.5/100 from 8 samples.
- Weakest measured pairing (min 5 samples): NVIDIA GeForce RTX 4090 + Intel Core i9-13900KF at 76.5/100 from 9 samples — low scores typically indicate thermal throttling or power-limited systems, not a slow chip.
- Typical sustained-load GPU performance decay: 0.9%. Average thermal health: 97/100. Path-tracing stability: 94/100.
- Per-pairing scores are medians (outlier-resistant); pairings are labeled High (15+ samples), Moderate (5-14) or Low (<5) confidence.
