Intel® Core™ i5-14400T

The Intel Core i5-14400T is a desktop processor with a hybrid 10-core layout (6 performance cores + 4 efficiency cores) and 16 threads, built on the Raptor Lake architecture (Intel 7 process). It launched in Jan 2024. Clocks run from 1.5 GHz base to 4.5 GHz boost. A 20-MB L3 cache backs the cores (3.0 MB per core). It addresses DDR5, DDR4 memory up to 192 GB across 2 channels. The chip drops into the FCLGA1700 socket and exposes PCIe 5.0 (20 lanes). Rated TDP is 35 W. Notable platform capabilities: Deep Learning Boost, AVX-VNNI, Extended Page Tables (EPT), AES-NI.

The Intel Core i5-14400T scores 3,526 in single-core performance and 20,633 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,529 for overall performance, 18,348 for productivity performance, 17,695 for creator performance, 21,794 for engineering performance and 15,736 for gaming performance. Its multi-core throughput works out to 2,063 per core, 1,290 per thread and 590 per watt. Its computed efficiency index is 1,442. Its performance index is 106, so its overall performance is 6% above 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 i5-14400T scores 65,743 in integer math, 49,196 in floating-point math, 235,792 in compression, 13,270 in cryptography, 1,243 in physics simulation, 14,574 in vector SIMD, 73 in the prime sieve and 25,182 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 12% above in integer math, 7% above in floating-point math, 3% above in compression, 16% above in cryptography, 14% above in physics simulation, 6% below in vector SIMD, 9% above in the prime sieve and 11% above 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 i5-14400T has 10 physical cores and runs 16 logical threads. It uses a hybrid layout of 6 performance cores and 4 efficiency cores. It runs at a base clock of 1.50 GHz and boosts up to 4.50 GHz.
