Core i5-10400T

The Core i5-10400T is a 6-core / 12-thread processor, manufactured on a 14 nm process node. It reaches a maximum boost clock of 3.6 GHz from a base frequency of 2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 12 MB Intel® Smart Cache of L3 cache. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 9,789, placing it in the Budget performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,272.

The Core i5-10400T fits into the LGA1200 socket and supports PCIe 3.0 with 16 total PCIe lanes for expansion cards and storage. It supports DDR4-2666 memory at speeds up to DDR4-2666 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 128 GB across 2 channels (dual-channel doubles bandwidth). Integrated graphics: UHD Graphics 630 — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

The Core i5-10400T is primarily designed for Low Power Desktop. Virtualization: VT-x, VT-d, EPT — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the Ryzen 5 3400GE.

The Core i5-10400T has a rated TDP (Thermal Design Power) of 35 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. It ships with the Yes stock cooler. Recommended cooling: Stock.

At an average price of $100 (MSRP: $182), the Core i5-10400T delivers 98 PassMark points per dollar. Performance ranking position: #1321 out of all indexed processors.
