AMD® A6-6420B APU

The AMD A6-6420B APU is a desktop processor with 2 cores and 2 threads. It launched in Jan 2014. Clocks run from 4.0 GHz base to 4.2 GHz boost. It uses the FM2 socket. Rated TDP is 65 W.

The AMD A6-6420B APU scores 1,629 in single-core performance and 1,550 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,589 for overall performance, 3,288 for productivity performance, 3,785 for creator performance, 1,443 for engineering performance and 5,275 for gaming performance. Its multi-core throughput works out to 775 per core, 775 per thread and 24 per watt. Its computed efficiency index is 197. Its performance index is 20, so its overall performance is 80% 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.

Workload sub-scores (integer math, floating point, compression, encryption, physics, SIMD, prime sieve and sorting) are not recorded for the AMD A6-6420B APU.

The AMD A6-6420B APU has 2 physical cores and runs 2 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 A6-6420B APU is a desktop processor and belongs to the AMD AMD family. It launched in Jan 2014.

The AMD A6-6420B APU has 160 KB of L1 cache and 2 MB of L2 cache. That adds up to about 2.2 MB of cache, or 1.08 MB per core.

The AMD A6-6420B APU has a 2-level cache hierarchy: L1 at 160 KB and L2 at 2 MB. L2 is the largest level and makes up about 93% of the cache listed here.

The AMD A6-6420B APU includes integrated graphics (HD 8470D) and clocks the graphics up to 0.80 GHz.
