AMD® FX™-4320

The AMD FX-4320 is a desktop processor with 4 cores and 4 threads, built on the Piledriver architecture. It launched in Nov 2012. Clocks run from 4.0 GHz base to 4.2 GHz boost. A 4-MB L3 cache backs the cores (2.0 MB per core). It uses the AM3+ socket. Rated TDP is 95 W.

The AMD FX-4320 scores 1,564 in single-core performance and 3,172 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,227 for overall performance, 4,251 for productivity performance, 4,560 for creator performance, 3,053 for engineering performance and 5,485 for gaming performance. Its multi-core throughput works out to 793 per core, 793 per thread and 33 per watt. Its computed efficiency index is 229. Its performance index is 28, so its overall performance is 72% 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 FX-4320 scores 20,129 in integer math, 5,406 in floating-point math, 52,705 in compression, 955 in cryptography, 294 in physics simulation, 1,313 in vector SIMD, 16 in the prime sieve and 6,573 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 66% below in integer math, 88% below in floating-point math, 77% below in compression, 92% below in cryptography, 73% below in physics simulation, 92% below in vector SIMD, 76% below in the prime sieve and 71% 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 FX-4320 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 4.00 GHz and boosts up to 4.20 GHz.

The AMD FX-4320 is a desktop processor, belongs to the AMD FX family, uses the Piledriver architecture, carries the codename Vishera and is manufactured on a 32 nm process. It launched in Nov 2012.

The AMD FX-4320 has 192 KB of L1 cache, 4 MB of L2 cache and 4 MB of L3 cache. That adds up to about 8.2 MB of cache, or 2.05 MB per core.

The AMD FX-4320 has a 3-level cache hierarchy: L1 at 192 KB, L2 at 4 MB and L3 at 4 MB. L2 is the largest level and makes up about 49% of the cache listed here.

The AMD FX-4320 uses the AM3+ socket.

The AMD FX-4320 has a rated TDP of 95 W.
