Connectivity
Intel Socket 1151 The Intel Core i5-8400 was a desktop processor with 6 cores, launched in October 2017, at an MSRP of $182. It is part of the Core i5 lineup, using the Coffee Lake architecture with Socket 1151. Core i5-8400 has 9 MB of L3 cache and operates at 2.8 GHz by default, but can boost up to 4 GHz, depending on the workload. Intel is making the Core i5-8400 on a 14 nm production node, the transistor count is unknown. The multiplier is locked on Core i5-8400, which limits its overclocking potential. With a TDP of 65 W, the Core i5-8400 consumes typical power levels for a modern PC. Intel's processor supports DDR4 memory with a dual-channel interface. The highest officially supported memory speed is 2666 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the machine, Core i5-8400 uses a PCI-Express Gen 3 connection. This processor features the UHD Graphics 630 integrated graphics solution. Hardware virtualization is available on the Core i5-8400, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512. Physical

Notes
| Motherboards based on Intel 100 and 200 series chipsets feature a physically identical LGA1151 socket but are made electrically incompatible without minor modifications. When correctly modified, these motherboards will work with Coffee Lake processors. UHD Graphics dynamic frequency: 350-1050 MHz |
