Intel® Core™ i7-4771

The Intel Core i7-4771 is a desktop processor with 4 cores and 8 threads, built on the Haswell architecture (22 nm process). It launched in Jul 2013. Clocks run from 3.5 GHz base to 3.9 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR3 memory up to 32 GB across 2 channels. The chip drops into the FCLGA1150 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 84 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i7-4771 scores 2,193 in single-core performance and 7,146 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,959 for overall performance, 7,715 for productivity performance, 7,878 for creator performance, 6,878 for engineering performance and 8,366 for gaming performance. Its multi-core throughput works out to 1,787 per core, 893 per thread and 85 per watt. Its computed efficiency index is 432. Its performance index is 49, so its overall performance is 51% 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 i7-4771 scores 25,503 in integer math, 12,724 in floating-point math, 110,985 in compression, 2,030 in cryptography, 502 in physics simulation, 6,493 in vector SIMD, 31 in the prime sieve and 14,287 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 57% below in integer math, 72% below in floating-point math, 51% below in compression, 82% below in cryptography, 54% below in physics simulation, 58% below in vector SIMD, 54% below in the prime sieve and 37% 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 i7-4771 has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 3.50 GHz and boosts up to 3.90 GHz.
