AMD® Ryzen™ 5 PRO 8540U

The AMD Ryzen 5 PRO 8540U is a laptop processor with 6 cores and 12 threads, built on the Zen 4 architecture. It launched in 2024. Clocks run from 3.2 GHz base to 4.9 GHz boost. A 16-MB L3 cache backs the cores (3.7 MB per core). It addresses DDR5 memory up to 256 GB across 2 channels. The chip drops into the FP7 socket and exposes PCIe 4.0 (14 lanes). Rated TDP is 28 W.

The AMD Ryzen 5 PRO 8540U scores 3,567 in single-core performance and 18,226 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,063 for overall performance, 16,841 for productivity performance, 16,445 for creator performance, 18,112 for engineering performance and 15,258 for gaming performance. Its multi-core throughput works out to 3,038 per core, 1,519 per thread and 651 per watt. Its computed efficiency index is 1,524. Its performance index is 100, equal to the Intel Core i5-12400. 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 5 PRO 8540U scores 56,566 in integer math, 34,797 in floating-point math, 204,991 in compression, 12,279 in cryptography, 978 in physics simulation, 15,335 in vector SIMD, 66 in the prime sieve and 24,679 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 4% below in integer math, 24% below in floating-point math, 10% below in compression, 7% above in cryptography, 10% below in physics simulation, 1% below in vector SIMD, 1% below in the prime sieve and 9% 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 5 PRO 8540U has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 3.20 GHz and boosts up to 4.90 GHz.
