Overview
SummaryThe 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.
Performance
10 metricsThe 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.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Workload Benchmarks
8 workloadsScores 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.
