Intel® Core™ i5-520UM

The Intel Core i5-520UM is a laptop processor with 2 cores and 4 threads (32 nm process). It launched in Jan 2010. Clocks run from 1.07 GHz base to 1.87 GHz boost. A 3-MB L3 cache backs the cores (1.8 MB per core). The chip drops into the FCBGA1288 socket and exposes PCIe 2.0 (16 lanes). Rated TDP is 18 W.

The Intel Core i5-520UM scores 709 in single-core performance and 932 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 813 for overall performance, 1,598 for productivity performance, 1,789 for creator performance, 868 for engineering performance and 2,360 for gaming performance. Its multi-core throughput works out to 466 per core, 233 per thread and 52 per watt. Its computed efficiency index is 192. Its performance index is 10, so its overall performance is 90% 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 Core i5-520UM scores 3,930 in integer math, 1,791 in floating-point math, 14,077 in compression, 318 in cryptography, 114 in physics simulation, 394 in vector SIMD, 6 in the prime sieve and 1,928 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 93% below in integer math, 96% below in floating-point math, 94% below in compression, 97% below in cryptography, 90% below in physics simulation, 97% below in vector SIMD, 91% below in the prime sieve and 91% 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 Core i5-520UM has 2 physical cores and runs 4 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 1.07 GHz and boosts up to 1.87 GHz.

The Intel Core i5-520UM is a laptop processor, belongs to the Intel Core i5 family and is manufactured on a 32 nm process. It launched in Jan 2010.

The Intel Core i5-520UM has 128 KB of L1 cache, 512 KB of L2 cache and 3 MB of L3 cache. That adds up to about 3.6 MB of cache, or 1.81 MB per core. Each core has 256 KB of private L2 cache.

The Intel Core i5-520UM has a 3-level cache hierarchy: L1 at 128 KB, L2 at 512 KB and L3 at 3 MB. L3 is the largest level and makes up about 83% of the cache listed here.

The Intel Core i5-520UM includes integrated graphics (HD Graphics) and clocks the graphics up to 0.50 GHz.

The Intel Core i5-520UM uses the FCBGA1288 socket, supports PCI Express 2.0 and provides up to 16 PCIe lanes.

The Intel Core i5-520UM has a rated TDP of 18 W.
