Intel · Core i9-X · 2019 · LGA2066
The Intel Core i9-10940X is a desktop processor with 14 cores, released in 2019 at an MSRP of $784. It is part of the Core i9-X lineup, using the Cascade X platform, and fits the LGA2066 socket. Internally, it is built on the "Cascade Lake-X" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 28 threads for improved parallelism. The Core i9-10940X has a base clock of 3.3 GHz and can boost up to 4.8 GHz depending on workload and thermal headroom. Intel manufactures the "Cascade Lake-X" silicon on a 14nm process node. The multiplier is unlocked, making overclocking straightforward. This processor supports DDR4 memory. With a TDP of 165W, the Core i9-10940X runs hot and requires a capable cooling setup. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of 32KB/core of L1, 1MB/core of L2, and 19.25MB of L3 cache.
14-core Cascade Lake-X. The 10980XE (18-core) completes the Cascade X lineup and is already in the database.
