AMD® Athlon™ 300U

The AMD Athlon 300U is a laptop processor with 2 cores and 4 threads. It launched in Jan 2019. Clocks run from 2.4 GHz base to 3.3 GHz boost. A 4-MB L3 cache backs the cores (2.6 MB per core). It supports DDR4 memory. It uses the FP5 socket. Rated TDP is 15 W.

The AMD Athlon 300U scores 1,734 in single-core performance and 3,806 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,569 for overall performance, 4,902 for productivity performance, 5,215 for creator performance, 3,544 for engineering performance and 6,154 for gaming performance. Its multi-core throughput works out to 1,903 per core, 952 per thread and 254 per watt. Its computed efficiency index is 663. Its performance index is 32, so its overall performance is 68% 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 300U scores 12,287 in integer math, 6,271 in floating-point math, 49,404 in compression, 3,258 in cryptography, 251 in physics simulation, 1,849 in vector SIMD, 11 in the prime sieve and 5,738 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 79% below in integer math, 86% below in floating-point math, 78% below in compression, 72% below in cryptography, 77% below in physics simulation, 88% below in vector SIMD, 84% below in the prime sieve and 75% 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 300U has 2 physical cores and runs 4 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 2.40 GHz and boosts up to 3.30 GHz.

The AMD Athlon 300U is a laptop processor and belongs to the AMD Athlon family. It launched in Jan 2019.

The AMD Athlon 300U has 192 KB of L1 cache, 1 MB of L2 cache and 4 MB of L3 cache. That adds up to about 5.2 MB of cache, or 2.60 MB per core. Each core has 512 KB of private L2 cache.

The AMD Athlon 300U has a 3-level cache hierarchy: L1 at 192 KB, L2 at 1 MB and L3 at 4 MB. L3 is the largest level and makes up about 77% of the cache listed here.

The AMD Athlon 300U supports DDR4 memory, uses 2 memory channels, runs memory at up to 2,400 MT/s and delivers up to 38.4 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The AMD Athlon 300U uses the FP5 socket.

The AMD Athlon 300U has a rated TDP of 15 W.
