Intel® Celeron® M 520

The Intel Celeron M 520 is a laptop processor with 1 cores and 1 threads. Rated TDP is 30 W.

The Intel Celeron M 520 scores 505 in single-core performance and 239 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 347 for overall performance, 862 for productivity performance, 1,040 for creator performance, 219 for engineering performance and 1,575 for gaming performance. Its multi-core throughput works out to 239 per core, 239 per thread and 8 per watt. Its computed efficiency index is 63. Its performance index is 4, so its overall performance is 96% 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 Intel Celeron M 520 scores 959 in integer math, 520 in floating-point math, 5,418 in compression, 70 in cryptography, 33 in physics simulation, 89 in vector SIMD, 1 in the prime sieve and 681 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 98% below in integer math, 99% below in floating-point math, 98% below in compression, 99% below in cryptography, 97% below in physics simulation, 99% below in vector SIMD, 99% below in the prime sieve and 97% 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 Intel Celeron M 520 has 1 physical core and runs 1 logical thread. 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 1.60 GHz.

The Intel Celeron M 520 is a laptop processor and belongs to the Intel Celeron family.

The Intel Celeron M 520 has 64 KB of L1 cache and 1 MB of L2 cache. That adds up to about 1.1 MB of cache, or 1.06 MB per core. Each core has 1 MB of private L2 cache.

The Intel Celeron M 520 has a 2-level cache hierarchy: L1 at 64 KB and L2 at 1 MB. L2 is the largest level and makes up about 94% of the cache listed here.

The Intel Celeron M 520 has a rated TDP of 30 W.
