AMD® FX™-8320

The AMD FX-8320 is a desktop processor with 8 cores and 8 threads, built on the Piledriver architecture. It launched in Oct 2012. Clocks run from 3.5 GHz base to 4.0 GHz boost. A 8-MB L3 cache backs the cores (2.0 MB per core). It uses the AM3+ socket. Rated TDP is 125 W.

The AMD FX-8320 scores 1,465 in single-core performance and 5,476 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,832 for overall performance, 5,610 for productivity performance, 5,649 for creator performance, 5,613 for engineering performance and 5,764 for gaming performance. Its multi-core throughput works out to 685 per core, 685 per thread and 44 per watt. Its computed efficiency index is 253. Its performance index is 35, so its overall performance is 65% 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-8320 scores 37,083 in integer math, 9,922 in floating-point math, 93,031 in compression, 1,683 in cryptography, 472 in physics simulation, 2,339 in vector SIMD, 28 in the prime sieve and 11,601 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 37% below in integer math, 78% below in floating-point math, 59% below in compression, 85% below in cryptography, 57% below in physics simulation, 85% below in vector SIMD, 58% below in the prime sieve and 49% 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-8320 has 8 physical cores and runs 8 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 4.00 GHz.

The AMD FX-8320 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 Oct 2012.

The AMD FX-8320 has 384 KB of L1 cache, 8 MB of L2 cache and 8 MB of L3 cache. That adds up to about 16.4 MB of cache, or 2.05 MB per core.

The AMD FX-8320 has a 3-level cache hierarchy: L1 at 384 KB, L2 at 8 MB and L3 at 8 MB. L2 is the largest level and makes up about 49% of the cache listed here.

The AMD FX-8320 uses the AM3+ socket.

The AMD FX-8320 has a rated TDP of 125 W.
