What the Core i5-14400T is
The Core i5-14400T is a 10-core and 16-thread desktop processor that Intel launched on January 8, 2024 as the low-power 14th Gen i5. Six Performance-cores with 12 threads plus 4 Efficient-cores give 16 threads at 1.5 GHz P-core base and up to 4.5 GHz P-core turbo with 3.5 GHz E-core turbo. Cache is 20 MB of Smart Cache with 9.5 MB of L2. Processor base power is 35 W, which fits small-form office PCs with limited airflow.
UHD Graphics 730 with 24 execution units at up to 1.55 GHz cover office displays through HDMI, DisplayPort and eDP. Four-display support and Quick Sync video come from the Raptor Lake die. DDR5-4800 or DDR4-3200 board options allow fleet reuse during refreshes.
Quiet offices and lab nodes fit here. Ten cores keep multitasking smooth at 35 W, while the 4.5 GHz peak preserves UI snap. Buyers who need faster bursts should take the 65 W 14400 with 4.7 GHz turbo instead, since this T part trades 0.2 GHz and base power for thermals.
Socket and motherboard compatibility
The 14400T fits LGA 1700 on 600 and 700 series boards with Raptor Lake Refresh firmware. H610, B660, B760, H770, Z690 and Z790 list the T SKU where BIOS is current. The FCLGA1700 package uses the 78 by 78 mm cooler pattern.
Memory is DDR5-4800 or DDR4-3200 in two channels up to 192 GB. DDR4 boards help offices reuse modules, while DDR5 boards give graphics bandwidth. ECC on W680 suits entry servers at ten cores.
Shoppers compare T low-power parts against non-T twins on base and turbo. The 14400T trails the 65 W part by 1.0 GHz base and 0.2 GHz boost for 30 W less power. The Socket vs chipset: what decides whether a CPU works guide explains 600 series updates for Raptor Lake-R.
Memory, PCIe and cooling
DDR5-4800 or DDR4-3200 in dual channels feeds ten cores with ease. Multitasking benefits from dual modules. Capacity planning follows officeVM and browser loads rather than speed.
PCIe gives 16 Gen5 plus 4 Gen4 lanes for graphics and NVMe. Small boards wire one x16 slot and one Gen4 SSD. No extra lanes are needed for office I/O.
Cooling is 35 W low-profile with quiet fans. Short turbo peaks need only brief airflow. Dust control preserves the 4.5 GHz burst feel.
Upgrade paths
The LGA socket allows moves on the same board, such as to 65 W i5 parts where cooling allows. Memory and NVMe can also grow. BIOS must list the target.
Longer steps go to 14-core i5 parts without changing boards. A working 14400T lasts office years. A move to LGA 1851 needs a new board.
Frequently asked questions
What socket does the Core i5-14400T use?
It uses LGA 1700 on 600 and 700 series boards with Raptor Lake Refresh support.
