AMD® Ryzen™ AI Embedded P121

The AMD Ryzen AI Embedded P121 is a embedded processor with a hybrid 4-core layout (1 performance cores + 3 efficiency cores) and 8 threads. It launched in 2026. A 8-MB L3 cache backs the cores (3.1 MB per core). It supports DDR5, LPDDR5X memory. Notable platform capabilities: Neural Processing Unit (NPU), AVX-512.

The AMD Ryzen AI Embedded P121 scores 3,745 in single-core performance and 13,348 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,070 for overall performance, 13,919 for productivity performance, 14,082 for creator performance, 12,847 for engineering performance and 14,572 for gaming performance. Its multi-core throughput works out to 3,337 per core and 1,669 per thread. Its performance index is 88, so its overall performance is 12% 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 AI Embedded P121 scores 39,924 in integer math, 26,870 in floating-point math, 154,390 in compression, 7,543 in cryptography, 775 in physics simulation, 11,057 in vector SIMD, 47 in the prime sieve and 16,853 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 32% below in integer math, 41% below in floating-point math, 32% below in compression, 34% below in cryptography, 29% below in physics simulation, 29% below in vector SIMD, 30% below in the prime sieve and 26% 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 AI Embedded P121 has 4 physical cores and runs 8 logical threads. It uses a hybrid layout of 1 performance cores and 3 efficiency cores. It runs 2 threads per core.
