Intel® Core™ i7-5550U

The Intel Core i7-5550U is a laptop processor with 2 cores and 4 threads, built on the Broadwell architecture (14 nm process). It launched in Jan 2015. Clocks run from 2.0 GHz base to 3.0 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 FCBGA1168 socket and exposes PCIe 2.0 (12 lanes). Rated TDP is 15 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i7-5550U scores 1,625 in single-core performance and 2,780 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,125 for overall performance, 4,082 for productivity performance, 4,454 for creator performance, 2,589 for engineering performance and 5,570 for gaming performance. Its multi-core throughput works out to 1,390 per core, 695 per thread and 185 per watt. Its computed efficiency index is 549. Its performance index is 26, so its overall performance is 74% 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 i7-5550U scores 8,901 in integer math, 5,964 in floating-point math, 40,587 in compression, 714 in cryptography, 260 in physics simulation, 2,611 in vector SIMD, 13 in the prime sieve and 5,141 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 85% below in integer math, 87% below in floating-point math, 82% below in compression, 94% below in cryptography, 76% below in physics simulation, 83% below in vector SIMD, 81% below in the prime sieve and 77% 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 i7-5550U has 2 physical cores and runs 4 logical threads. It runs 2 threads per core. It runs at a base clock of 2.00 GHz and boosts up to 3.00 GHz.
