Intel® Core™ i5-2540M

The Intel Core i5-2540M is a laptop processor with 2 cores and 4 threads, built on the Sandy Bridge architecture (32 nm process). It launched in Feb 2011. Clocks run from 2.6 GHz base to 3.3 GHz boost. A 3-MB L3 cache backs the cores (1.8 MB per core). The chip drops into the FCBGA1023 socket and exposes PCIe 2.0 (16 lanes). Rated TDP is 35 W.

The Intel Core i5-2540M scores 1,394 in single-core performance and 2,346 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,808 for overall performance, 3,477 for productivity performance, 3,800 for creator performance, 2,185 for engineering performance and 4,769 for gaming performance. Its multi-core throughput works out to 1,173 per core, 587 per thread and 67 per watt. Its computed efficiency index is 306. Its performance index is 22, so its overall performance is 78% 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 i5-2540M scores 8,521 in integer math, 3,256 in floating-point math, 37,274 in compression, 694 in cryptography, 239 in physics simulation, 1,594 in vector SIMD, 12 in the prime sieve and 5,566 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 86% below in integer math, 93% below in floating-point math, 84% below in compression, 94% below in cryptography, 78% below in physics simulation, 90% below in vector SIMD, 82% below in the prime sieve and 75% 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 i5-2540M 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 2.60 GHz and boosts up to 3.30 GHz.

The Intel Core i5-2540M is a laptop processor, belongs to the Intel Core i5 family, uses the Sandy Bridge architecture, carries the codename Sandy Bridge and is manufactured on a 32 nm process. It launched in Feb 2011.

The Intel Core i5-2540M 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 i5-2540M 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 i5-2540M includes integrated graphics (HD 3000) and clocks the graphics up to 1.30 GHz.

The Intel Core i5-2540M uses the FCBGA1023 socket, supports PCI Express 2.0 and provides up to 16 PCIe lanes.

The Intel Core i5-2540M has a rated TDP of 35 W.
