NVIDIA GeForce GTX 1660 Benchmark Results — All CPU Pairings Tested
NVIDIA GeForce GTX 1660 has been stress-tested in 16 distinct CPU pairings from 86 verified browser samples, with a sample-weighted Sustained Health Score of 68.4/100 (grade B). The strongest measured pairing is Intel Core i5-9400F Processor (9M Cache, up to 4.10 GHz) at 70/100; the weakest is Intel Core i5-10400F at 63.5/100. Typical sustained-load decay is 4% with thermal health around 94/100.
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 GTX 1660
- NVIDIA GeForce GTX 1660 has been measured in 16 distinct CPU pairings on UserBenchmark.org, totaling 86 verified browser stress-test samples.
- Sample-weighted median Sustained Health Score across all NVIDIA GeForce GTX 1660 configurations: 68.4/100 (grade B). This score measures performance retention under sustained load, not peak throughput.
- Best measured pairing (min 5 samples): NVIDIA GeForce GTX 1660 + Intel Core i5-9400F Processor (9M Cache, up to 4.10 GHz) at 70/100 from 15 samples.
- Weakest measured pairing (min 5 samples): NVIDIA GeForce GTX 1660 + Intel Core i5-10400F at 63.5/100 from 6 samples — low scores typically indicate thermal throttling or power-limited systems, not a slow chip.
- Typical sustained-load GPU performance decay: 4%. Average thermal health: 94/100. 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.
