AMD® Athlon™ II M300

The AMD Athlon II M300 is a laptop processor with 2 cores and 2 threads. It launched in Sep 2009. It uses the S1G3 socket. Rated TDP is 35 W.

The AMD Athlon II M300 scores 776 in single-core performance and 670 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 721 for overall performance, 1,522 for productivity performance, 1,765 for creator performance, 624 for engineering performance and 2,496 for gaming performance. Its multi-core throughput works out to 335 per core, 335 per thread and 19 per watt. Its computed efficiency index is 122. Its performance index is 9, so its overall performance is 91% 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 Athlon II M300 scores 2,061 in integer math, 1,656 in floating-point math, 16,829 in compression, 204 in cryptography, 73 in physics simulation, 227 in vector SIMD, 4 in the prime sieve and 2,085 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 97% below in integer math, 96% below in floating-point math, 93% below in compression, 98% below in cryptography, 93% below in physics simulation, 99% below in vector SIMD, 94% below in the prime sieve and 91% 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 Athlon II M300 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 2.00 GHz.

The AMD Athlon II M300 is a laptop processor and belongs to the AMD Athlon family. It launched in Sep 2009.

The AMD Athlon II M300 has 256 KB of L1 cache and 1 MB of L2 cache. That adds up to about 1.3 MB of cache, or 0.63 MB per core. Each core has 512 KB of private L2 cache.

The AMD Athlon II M300 has a 2-level cache hierarchy: L1 at 256 KB and L2 at 1 MB. L2 is the largest level and makes up about 80% of the cache listed here.

The AMD Athlon II M300 uses the S1G3 socket.
