AMD® Ryzen™ AI Max 385

The AMD Ryzen AI Max 385 is a desktop processor with 8 cores and 16 threads, built on the 8x Zen 5 architecture (4 nm process). It launched in Jan 2025. Clocks run from 3.6 GHz base to 5.0 GHz boost. A 32-MB L3 cache backs the cores (5.1 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 385 scores 4,029 in single-core performance and 33,476 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 11,614 for overall performance, 27,400 for productivity performance, 25,664 for creator performance, 34,313 for engineering performance and 20,456 for gaming performance. Its multi-core throughput works out to 4,185 per core, 2,092 per thread and 609 per watt. Its computed efficiency index is 1,566. Its performance index is 144, so its overall performance is 44% 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 385 scores 107,046 in integer math, 71,105 in floating-point math, 406,505 in compression, 19,926 in cryptography, 1,889 in physics simulation, 33,873 in vector SIMD, 165 in the prime sieve and 43,725 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 82% above in integer math, 55% above in floating-point math, 78% above in compression, 73% above in cryptography, 73% above in physics simulation, 118% above in vector SIMD, 146% above in the prime sieve and 93% 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 385 has 8 physical cores and runs 16 logical threads. It runs 2 threads per core. It runs at a base clock of 3.60 GHz and boosts up to 5.00 GHz.
