Intel® Core™ M-5Y31

The Intel Core M-5Y31 is a laptop processor with 2 cores and 4 threads, built on the Broadwell architecture (14 nm process). It launched in Oct 2014. Clocks run from 900 MHz base to 2.4 GHz boost. A 4-MB L3 cache backs the cores (2.3 MB per core). It addresses LPDDR3 memory up to 16 GB across 2 channels. The chip drops into the FCBGA1234 socket and exposes PCIe 2.0 (12 lanes). Rated TDP is 4.5 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core M-5Y31 scores 1,231 in single-core performance and 1,893 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,527 for overall performance, 2,954 for productivity performance, 3,257 for creator performance, 1,763 for engineering performance and 4,166 for gaming performance. Its multi-core throughput works out to 947 per core, 473 per thread and 421 per watt. Its computed efficiency index is 720. Its performance index is 19, so its overall performance is 81% 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 M-5Y31 scores 5,933 in integer math, 3,703 in floating-point math, 30,230 in compression, 525 in cryptography, 203 in physics simulation, 1,380 in vector SIMD, 9 in the prime sieve and 3,420 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 90% below in integer math, 92% below in floating-point math, 87% below in compression, 95% below in cryptography, 81% below in physics simulation, 91% below in vector SIMD, 87% below in the prime sieve and 85% 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 M-5Y31 has 2 physical cores and runs 4 logical threads. It runs 2 threads per core. It runs at a base clock of 0.90 GHz and boosts up to 2.40 GHz.

The Intel Core M-5Y31 is a laptop processor, belongs to the Intel Core M family, uses the Broadwell architecture, carries the codename Broadwell and is manufactured on a 14 nm process. It launched in Oct 2014.

The Intel Core M-5Y31 has 128 KB of L1 cache, 512 KB of L2 cache and 4 MB of L3 cache. That adds up to about 4.6 MB of cache, or 2.31 MB per core. Each core has 256 KB of private L2 cache.

The Intel Core M-5Y31 has a 3-level cache hierarchy: L1 at 128 KB, L2 at 512 KB and L3 at 4 MB. L3 is the largest level and makes up about 86% of the cache listed here.

The Intel Core M-5Y31 supports LPDDR3 memory, addresses up to 16 GB of memory and uses 2 memory channels. It does not support DDR5 and DDR4 memory.
