AMD® Phenom™ II X2 545

The AMD Phenom II X2 545 is a desktop processor with 2 cores and 2 threads. A 6-MB L3 cache backs the cores (3.6 MB per core). Rated TDP is 80 W.

The AMD Phenom II X2 545 scores 1,177 in single-core performance and 1,224 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,200 for overall performance, 2,443 for productivity performance, 2,792 for creator performance, 1,140 for engineering performance and 3,837 for gaming performance. Its multi-core throughput works out to 612 per core, 612 per thread and 15 per watt. Its computed efficiency index is 134. Its performance index is 15, so its overall performance is 85% 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 Phenom II X2 545 scores 3,352 in integer math, 2,521 in floating-point math, 25,462 in compression, 329 in cryptography, 134 in physics simulation, 599 in vector SIMD, 10 in the prime sieve and 3,246 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 94% below in integer math, 95% below in floating-point math, 89% below in compression, 97% below in cryptography, 88% below in physics simulation, 96% below in vector SIMD, 85% below in the prime sieve and 86% 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 Phenom II X2 545 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 3.00 GHz.

The AMD Phenom II X2 545 is a desktop processor and belongs to the AMD Phenom family.

The AMD Phenom II X2 545 has 256 KB of L1 cache, 1 MB of L2 cache and 6 MB of L3 cache. That adds up to about 7.3 MB of cache, or 3.63 MB per core. Each core has 512 KB of private L2 cache.

The AMD Phenom II X2 545 has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 6 MB. L3 is the largest level and makes up about 83% of the cache listed here.

The AMD Phenom II X2 545 has a rated TDP of 80 W.
