AMD® Ryzen™ Ai 9 Hx 475

The AMD Ryzen Ai 9 Hx 475 is a laptop processor with a hybrid 12-core layout (4 performance cores + 8 efficiency cores) and 24 threads, built on the Zen 5 (Gorgon Point) architecture (4 nm process). It launched in Jan 2026. Clocks run from 2.0 GHz base to 5.2 GHz boost. A 24-MB L3 cache backs the cores (3.1 MB per core). It addresses DDR5, LPDDR5X memory up to 256 GB across 2 channels. The chip drops into the FP8 socket and exposes PCIe 4.0 (16 lanes). Rated TDP is 54 W.

The AMD Ryzen Ai 9 Hx 475 scores 4,285 in single-core performance and 38,807 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,895 for overall performance, 31,224 for productivity performance, 29,057 for creator performance, 42,203 for engineering performance and 22,557 for gaming performance. Its multi-core throughput works out to 3,234 per core, 1,617 per thread and 719 per watt. Its computed efficiency index is 1,755. Its performance index is 160, so its overall performance is 60% 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.

Scores 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 475 scores 129,887 in integer math, 83,387 in floating-point math, 513,507 in compression, 24,557 in cryptography, 1,989 in physics simulation, 36,335 in vector SIMD, 137 in the prime sieve and 53,213 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 121% above in integer math, 82% above in floating-point math, 125% above in compression, 114% above in cryptography, 82% above in physics simulation, 134% above in vector SIMD, 104% above in the prime sieve and 135% 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.

The AMD Ryzen Ai 9 Hx 475 has 12 physical cores and runs 24 logical threads. It uses a hybrid layout of 4 performance cores and 8 efficiency cores. It runs 2 threads per core. It runs at a base clock of 2.00 GHz and boosts up to 5.20 GHz.
