AMD® Ryzen™ 3 5400U

The AMD Ryzen 3 5400U is a laptop processor with 4 cores and 8 threads (7 nm process). It launched in Jan 2021. Clocks run from 2.6 GHz base to 4.0 GHz boost. A 8-MB L3 cache backs the cores (2.6 MB per core). It supports DDR4, LPDDR4 memory. The chip drops into the FP6 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 15 W. Notable platform capabilities: AMD-V (Hardware Virtualization), AMD SEV.

The AMD Ryzen 3 5400U scores 2,720 in single-core performance and 10,748 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 5,407 for overall performance, 10,794 for productivity performance, 10,807 for creator performance, 10,345 for engineering performance and 10,847 for gaming performance. Its multi-core throughput works out to 2,687 per core, 1,344 per thread and 717 per watt. Its computed efficiency index is 1,396. Its performance index is 67, so its overall performance is 33% 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.

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 3 5400U scores 38,088 in integer math, 20,930 in floating-point math, 127,118 in compression, 7,998 in cryptography, 481 in physics simulation, 8,623 in vector SIMD, 28 in the prime sieve and 13,709 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 35% below in integer math, 54% below in floating-point math, 44% below in compression, 30% below in cryptography, 56% below in physics simulation, 44% below in vector SIMD, 58% below in the prime sieve and 39% below 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 3 5400U has 4 physical cores and runs 8 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 2.60 GHz and boosts up to 4.00 GHz.
