AMD® Opteron™ X3421 APU

The AMD Opteron X3421 APU is a server processor with 4 cores and 4 threads (28 nm process). It launched in Jun 2017. Clocks run from 2.1 GHz base to 3.4 GHz boost. Rated TDP is 35 W.

The AMD Opteron X3421 APU scores 1,418 in single-core performance and 3,306 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,165 for overall performance, 4,134 for productivity performance, 4,371 for creator performance, 3,182 for engineering performance and 5,081 for gaming performance. Its multi-core throughput works out to 827 per core, 827 per thread and 95 per watt. Its computed efficiency index is 366. Its performance index is 27, so its overall performance is 73% 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 Opteron X3421 APU scores 17,720 in integer math, 5,478 in floating-point math, 55,307 in compression, 1,049 in cryptography, 244 in physics simulation, 1,894 in vector SIMD, 11 in the prime sieve and 5,928 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 70% below in integer math, 88% below in floating-point math, 76% below in compression, 91% below in cryptography, 78% below in physics simulation, 88% below in vector SIMD, 84% below in the prime sieve and 74% 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 Opteron X3421 APU 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 2.10 GHz and boosts up to 3.40 GHz.

The AMD Opteron X3421 APU is a server processor, belongs to the AMD Opteron family and is manufactured on a 28 nm process. It launched in Jun 2017.

The AMD Opteron X3421 APU 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 Opteron X3421 APU 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 Opteron X3421 APU includes integrated graphics (Radeon 7) and clocks the graphics up to 0.80 GHz.

The AMD Opteron X3421 APU has a rated TDP of 35 W.
