AMD® Athlon™ X2 340

The AMD Athlon X2 340 is a desktop processor with 2 cores and 2 threads. It launched in Oct 2012. Clocks run from 3.2 GHz base to 3.6 GHz boost. It supports DDR3 memory. It uses the FM2 socket. Rated TDP is 65 W.

The AMD Athlon X2 340 scores 1,270 in single-core performance and 1,334 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,302 for overall performance, 2,645 for productivity performance, 3,020 for creator performance, 1,242 for engineering performance and 4,144 for gaming performance. Its multi-core throughput works out to 667 per core, 667 per thread and 21 per watt. Its computed efficiency index is 161. Its performance index is 16, so its overall performance is 84% 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 X2 340 scores 8,338 in integer math, 2,377 in floating-point math, 21,750 in compression, 410 in cryptography, 125 in physics simulation, 555 in vector SIMD, 5 in the prime sieve and 2,716 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 86% below in integer math, 95% below in floating-point math, 90% below in compression, 96% below in cryptography, 89% below in physics simulation, 96% below in vector SIMD, 93% below in the prime sieve and 88% 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 X2 340 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 3.20 GHz and boosts up to 3.60 GHz.

The AMD Athlon X2 340 is a desktop processor and belongs to the AMD Athlon family. It launched in Oct 2012.

The AMD Athlon X2 340 has 1 MB of L2 cache. That adds up to about 1.0 MB of cache, or 0.50 MB per core. Feex has no recorded L1 cache size for this processor.

The AMD Athlon X2 340 supports DDR3 memory and runs memory at up to 1,866 MT/s. It does not support DDR5, DDR4 and LPDDR memory.

The AMD Athlon X2 340 uses the FM2 socket.

The AMD Athlon X2 340 has a rated TDP of 65 W.
