Six-core desktop processor for everyday workloads
The Intel Core i5-8400 delivers six cores and six threads at a base frequency of 2.8 GHz. It fits the LGA 1151 socket and supports dual-channel DDR4 2666 memory up to 128 GB. A 65 W thermal design power keeps cooling requirements modest for typical builds.
Sustained multi-threaded performance at fixed power
With six physical cores the chip handles parallel workloads such as compilation, rendering or virtualisation without relying on short burst speeds. The 9 MB L3 cache reduces latency when data sets exceed individual core caches. Thermal output remains steady at the rated 65 W during extended sessions.
LGA 1151 mounting and mainstream platform
The processor drops into existing LGA 1151 motherboards that support the Coffee Lake architecture. Dual memory channels and a maximum capacity of 128 GB give flexibility for memory-heavy applications. The 65 W envelope allows standard tower coolers to maintain low noise levels in daily use.

คำถามเกี่ยวกับสินค้านี้
How loud and hot does the 65W i5-8400 get when it runs all day?
The processor has a 65W thermal design power, so a standard LGA 1151 cooler keeps temperatures and fan noise modest during continuous loads.
What motherboard and memory must I already own for this LGA 1151 CPU to work?
You need an LGA 1151 socket motherboard and DDR4 2666 modules; the controller supports two channels up to 128 GB total.
Will the i5-8400 run on my older LGA 1155 board alongside my existing parts?
No, the i5-8400 requires an LGA 1151 socket; it is physically and electrically incompatible with LGA 1155 motherboards.
