Intel® Core™ i7-5775R

The Intel Core i7-5775R is a desktop processor with 4 cores and 8 threads, built on the Broadwell architecture (14 nm process). It launched in Apr 2015. Clocks run from 3.3 GHz base to 3.8 GHz boost. A 6-MB L3 cache backs the cores (1.8 MB per core). Maximum addressable memory is 32 GB. The chip drops into the FCBGA1364 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 65 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i7-5775R scores 2,270 in single-core performance and 7,483 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,121 for overall performance, 8,042 for productivity performance, 8,202 for creator performance, 7,202 for engineering performance and 8,681 for gaming performance. Its multi-core throughput works out to 1,871 per core, 935 per thread and 115 per watt. Its computed efficiency index is 511. Its performance index is 51, so its overall performance is 49% 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 i7-5775R scores 24,586 in integer math, 15,313 in floating-point math, 115,300 in compression, 2,019 in cryptography, 901 in physics simulation, 5,797 in vector SIMD, 48 in the prime sieve and 13,378 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 58% below in integer math, 67% below in floating-point math, 49% below in compression, 82% below in cryptography, 17% below in physics simulation, 63% below in vector SIMD, 28% below in the prime sieve and 41% 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 i7-5775R has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 3.30 GHz and boosts up to 3.80 GHz.
