AMD® A9-9400

The AMD A9-9400 is a laptop processor with 2 cores and 2 threads. It launched in Nov 2016. Clocks run from 2.4 GHz base to 3.2 GHz boost. It uses the FP4 socket. Rated TDP is 10 W.

The AMD A9-9400 scores 1,187 in single-core performance and 1,330 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,256 for overall performance, 2,526 for productivity performance, 2,868 for creator performance, 1,239 for engineering performance and 3,894 for gaming performance. Its multi-core throughput works out to 665 per core, 665 per thread and 133 per watt. Its computed efficiency index is 397. Its performance index is 16, so its overall performance is 84% 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 A9-9400 scores 7,194 in integer math, 2,268 in floating-point math, 20,430 in compression, 406 in cryptography, 104 in physics simulation, 750 in vector SIMD, 5 in the prime sieve and 2,307 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 88% below in integer math, 95% below in floating-point math, 91% below in compression, 96% below in cryptography, 90% below in physics simulation, 95% below in vector SIMD, 93% below in the prime sieve and 90% 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 A9-9400 has 2 physical cores and runs 2 logical threads. It does not use a hybrid performance and efficiency core layout. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.40 GHz and boosts up to 3.20 GHz.

The AMD A9-9400 is a laptop processor and belongs to the AMD A-Series family. It launched in Nov 2016.

The AMD A9-9400 has 256 KB of L1 cache and 2 MB of L2 cache. That adds up to about 2.3 MB of cache, or 1.13 MB per core.

The AMD A9-9400 has a 2-level cache hierarchy: L1 at 256 KB and L2 at 2 MB. L2 is the largest level and makes up about 89% of the cache listed here.

The AMD A9-9400 uses the FP4 socket.

The AMD A9-9400 has a rated TDP of 10 W.
