Overview
SummaryThe AMD Ryzen Ai 9 Hx PRO 475 is a laptop processor with 12 cores and 24 threads (4 nm process). It launched in Jan 2026. A 24-MB L3 cache backs the cores (3.1 MB per core). It supports DDR5, LPDDR5X memory.
Performance
10 metricsThe AMD Ryzen Ai 9 Hx PRO 475 scores 4,237 in single-core performance and 36,108 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,369 for overall performance, 29,402 for productivity performance, 27,486 for creator performance, 39,267 for engineering performance and 21,738 for gaming performance. Its multi-core throughput works out to 3,009 per core and 1,505 per thread. Its performance index is 153, so its overall performance is 53% above the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Workload Benchmarks
8 workloadsScores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.
In the individual workload tests the AMD Ryzen Ai 9 Hx PRO 475 scores 126,346 in integer math, 79,327 in floating-point math, 456,347 in compression, 22,790 in cryptography, 1,863 in physics simulation, 31,456 in vector SIMD, 132 in the prime sieve and 48,046 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 115% above in integer math, 73% above in floating-point math, 100% above in compression, 98% above in cryptography, 71% above in physics simulation, 103% above in vector SIMD, 97% above in the prime sieve and 112% above in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.
