AMD® Ryzen™ AI Max 390

The AMD Ryzen AI Max 390 is a laptop processor with 12 cores and 24 threads, built on the 12x Zen 5 architecture (4 nm process). It launched in Jan 2025. Clocks run from 3.2 GHz base to 5.0 GHz boost. A 64-MB L3 cache backs the cores (6.4 MB per core). It addresses LPDDR5X memory up to 128 GB across 4 channels. The chip drops into the FP11 socket and exposes PCIe 4.0 (16 lanes). Rated TDP is 55 W.

The AMD Ryzen AI Max 390 scores 4,020 in single-core performance and 41,552 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,924 for overall performance, 32,637 for productivity performance, 30,090 for creator performance, 45,188 for engineering performance and 22,448 for gaming performance. Its multi-core throughput works out to 3,463 per core, 1,731 per thread and 756 per watt. Its computed efficiency index is 1,743. 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 Max 390 scores 146,519 in integer math, 90,594 in floating-point math, 487,145 in compression, 25,097 in cryptography, 2,761 in physics simulation, 38,716 in vector SIMD, 316 in the prime sieve and 53,113 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 149% above in integer math, 97% above in floating-point math, 114% above in compression, 118% above in cryptography, 153% above in physics simulation, 150% above in vector SIMD, 372% above in the prime sieve and 134% 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 Max 390 has 12 physical cores and runs 24 logical threads. It runs 2 threads per core. It runs at a base clock of 3.20 GHz and boosts up to 5.00 GHz. Its clock multiplier is unlocked for overclocking.
