Intel Core i9-11900K Benchmark Results — All GPU Pairings Tested
Intel Core i9-11900K has been stress-tested in 9 distinct GPU pairings from 40 verified browser samples, with a sample-weighted Sustained Health Score of 74.1/100 (grade B). The strongest measured pairing is NVIDIA GeForce RTX 3080 at 77/100; the weakest is NVIDIA GeForce RTX 3060 Ti at 73.5/100. Typical sustained-load decay is 1.2% with thermal health around 95/100.
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.
