AMD® Ryzen™ 5 7540U

The AMD Ryzen 5 7540U is a laptop processor with 6 cores and 12 threads, built on the Zen 4 architecture (4 nm process). It launched in May 2023. 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. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 5 7540U scores 3,499 in single-core performance and 18,526 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,051 for overall performance, 16,941 for productivity performance, 16,488 for creator performance, 18,410 for engineering performance and 15,129 for gaming performance. Its multi-core throughput works out to 3,088 per core, 1,544 per thread and 662 per watt. Its computed efficiency index is 1,522. 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 7540U scores 60,062 in integer math, 35,940 in floating-point math, 210,333 in compression, 12,497 in cryptography, 973 in physics simulation, 15,170 in vector SIMD, 67 in the prime sieve and 24,709 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 2% above in integer math, 22% below in floating-point math, 8% below in compression, 9% above in cryptography, 11% below in physics simulation, 2% below in vector SIMD, equal 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 7540U 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.
