DISC PROD SPCL SOURCING SEE NOTES
The Intel Core i5-8400 is a 6-core, 6-thread desktop processor from the 8th Generation Intel Core i5 Processors, code-named Coffee Lake. Operating at a base frequency of 2.80 GHz and capable of a Max Turbo Frequency of 4.00 GHz, this processor is built on a 14 nm lithography with a 65W TDP. It includes Intel UHD Graphics 630, supporting up to three displays with 4K resolution at 60Hz via DisplayPort or eDP. The processor supports up to 64 GB of DDR4-2666 memory across two channels and features 9 MB of cache. It is designed for single-socket FCLGA1151 configurations, making it suitable for standard business desktop builds requiring a balance of core count and clock speed for general office applications, multitasking, and moderate content consumption. The BX80684I58400 is a component for system integrators and IT departments building or upgrading desktop systems where a dedicated graphics card may not be necessary for daily operations.
