AMD® Ryzen™ AI 5 PRO 340

The AMD Ryzen AI 5 PRO 340 is a laptop processor with 6 cores and 12 threads (4 nm process). It launched in 2025. A 16-MB L3 cache backs the cores (3.7 MB per core). It supports DDR5, LPDDR5X memory.

The AMD Ryzen AI 5 PRO 340 scores 3,757 in single-core performance and 19,195 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,492 for overall performance, 17,737 for productivity performance, 17,320 for creator performance, 19,075 for engineering performance and 16,070 for gaming performance. Its multi-core throughput works out to 3,199 per core and 1,600 per thread. Its performance index is 105, so its overall performance is 5% 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 AI 5 PRO 340 scores 63,309 in integer math, 39,729 in floating-point math, 221,964 in compression, 11,230 in cryptography, 1,084 in physics simulation, 15,758 in vector SIMD, 74 in the prime sieve and 24,374 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 7% above in integer math, 13% below in floating-point math, 3% below in compression, 2% below in cryptography, 1% below in physics simulation, 2% above in vector SIMD, 10% above in the prime sieve and 8% 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 AI 5 PRO 340 has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 2.00 GHz.
