AMD® Ryzen™ 3 8440U

The AMD Ryzen 3 8440U is a desktop processor with 4 cores and 8 threads, built on the 1x Zen 4 , 3x Zen 4c architecture (4 nm process). It launched in Dec 2023. Clocks run from 3.0 GHz base to 4.7 GHz boost. A 8-MB L3 cache backs the cores (3.0 MB per core). It supports DDR5 memory. The chip drops into the FP7/FP7r2 socket and exposes PCIe 4.0 (14 lanes). Rated TDP is 28 W.

The AMD Ryzen 3 8440U scores 3,344 in single-core performance and 11,957 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,323 for overall performance, 12,454 for productivity performance, 12,596 for creator performance, 11,509 for engineering performance and 13,021 for gaming performance. Its multi-core throughput works out to 2,989 per core, 1,495 per thread and 427 per watt. Its computed efficiency index is 1,195. Its performance index is 78, so its overall performance is 22% below 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.

Workload sub-scores (integer math, floating point, compression, encryption, physics, SIMD, prime sieve and sorting) are not recorded for the AMD Ryzen 3 8440U.
