Intel® Core™ i5-11400T

The Intel Core i5-11400T is a desktop processor with 6 cores and 12 threads, built on the Rocket Lake architecture (14 nm process). It launched in Jan 2021. Clocks run from 1.3 GHz base to 3.7 GHz boost. A 12-MB L3 cache backs the cores (2.6 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCLGA1200 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 35 W. Notable platform capabilities: Gaussian Neural Accelerator, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core i5-11400T scores 2,483 in single-core performance and 13,067 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 5,696 for overall performance, 11,970 for productivity performance, 11,656 for creator performance, 12,985 for engineering performance and 10,716 for gaming performance. Its multi-core throughput works out to 2,178 per core, 1,089 per thread and 373 per watt. Its computed efficiency index is 963. Its performance index is 71, so its overall performance is 29% 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 i5-11400T scores 45,068 in integer math, 26,620 in floating-point math, 153,864 in compression, 7,998 in cryptography, 697 in physics simulation, 10,155 in vector SIMD, 43 in the prime sieve and 19,112 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 23% below in integer math, 42% below in floating-point math, 33% below in compression, 30% below in cryptography, 36% below in physics simulation, 35% below in vector SIMD, 36% below in the prime sieve and 16% 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 i5-11400T has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 1.30 GHz and boosts up to 3.70 GHz.
