AMD® Athlon™ X4 950

The AMD Athlon X4 950 is a desktop processor with 4 cores and 4 threads. It launched in Jul 2017. Clocks run from 3.5 GHz base to 3.8 GHz boost. It supports DDR4 memory. It uses the AM4 socket. Rated TDP is 65 W.

The AMD Athlon X4 950 scores 1,600 in single-core performance and 3,537 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,379 for overall performance, 4,539 for productivity performance, 4,825 for creator performance, 3,404 for engineering performance and 5,684 for gaming performance. Its multi-core throughput works out to 884 per core, 884 per thread and 54 per watt. Its computed efficiency index is 295. Its performance index is 29, so its overall performance is 71% 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 X4 950 scores 19,007 in integer math, 5,928 in floating-point math, 60,151 in compression, 1,109 in cryptography, 239 in physics simulation, 2,094 in vector SIMD, 11 in the prime sieve and 6,298 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 68% below in integer math, 87% below in floating-point math, 74% below in compression, 90% below in cryptography, 78% below in physics simulation, 86% below in vector SIMD, 84% below in the prime sieve and 72% 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 X4 950 has 4 physical cores and runs 4 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 3.50 GHz and boosts up to 3.80 GHz.

The AMD Athlon X4 950 is a desktop processor and belongs to the AMD Athlon family. It launched in Jul 2017.

The AMD Athlon X4 950 has 512 KB of L1 cache and 4 MB of L2 cache. That adds up to about 4.5 MB of cache, or 1.13 MB per core.

The AMD Athlon X4 950 has a 2-level cache hierarchy: L1 at 512 KB and L2 at 4 MB. L2 is the largest level and makes up about 89% of the cache listed here.

The AMD Athlon X4 950 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 X4 950 uses the AM4 socket.

The AMD Athlon X4 950 has a rated TDP of 65 W.
