The Intel Core i7-7740X is a desktop processor with 4 cores, released in 2017. It is part of the Core i7-X lineup, using the Kaby Lake-X platform, and fits the LGA2066 socket. Internally, it is built on the "Kaby Lake-X" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 8 threads for improved parallelism. The Core i7-7740X has a base clock of 4.3 GHz and can boost up to 4.5 GHz depending on workload and thermal headroom. Intel manufactures the "Kaby Lake-X" silicon on a 14nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR4 memory. With a TDP of 112W, the Core i7-7740X sits in a typical power envelope for a modern desktop CPU. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 32KB/core of L1, 256KB/core of L2, and 8MB of L3 cache.
X-series part for the LGA2066 platform.
