AMD® Ryzen™ 9 9850HX

The AMD Ryzen 9 9850HX is a laptop processor with 12 cores and 24 threads, built on the Zen 5 architecture (4 nm process). It launched in Jan 2025. Clocks run from 3.0 GHz base to 5.2 GHz boost. A 64-MB L3 cache backs the cores (6.4 MB per core). It addresses DDR5 memory up to 96 GB across 2 channels. The chip drops into the FL1 socket and exposes PCIe 5.0 (28 lanes). Rated TDP is 55 W. Notable platform capabilities: AVX-512, AVX-VNNI, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 9 9850HX scores 4,461 in single-core performance and 51,722 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 15,190 for overall performance, 39,865 for productivity performance, 36,477 for creator performance, 56,248 for engineering performance and 26,314 for gaming performance. Its multi-core throughput works out to 4,310 per core, 2,155 per thread and 940 per watt. Its computed efficiency index is 2,048. Its performance index is 188, so its overall performance is 88% 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 9 9850HX scores 172,943 in integer math, 115,062 in floating-point math, 662,381 in compression, 32,139 in cryptography, 3,054 in physics simulation, 53,817 in vector SIMD, 323 in the prime sieve and 70,175 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 194% above in integer math, 151% above in floating-point math, 190% above in compression, 180% above in cryptography, 180% above in physics simulation, 247% above in vector SIMD, 382% above in the prime sieve and 210% 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 9 9850HX has 12 physical cores and runs 24 logical threads. It runs 2 threads per core. It runs at a base clock of 3.00 GHz and boosts up to 5.20 GHz.
