Intel · Core i9-X · 2018 · LGA2066
The Intel Core i9-9980XE is a desktop processor with 18 cores, released in 2018 at an MSRP of $1,979. It is part of the Core i9-X lineup, using the Skylake-X platform, and fits the LGA2066 socket. Internally, it is built on the "Skylake-X" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 36 threads for improved parallelism. The Core i9-9980XE has a base clock of 3 GHz and can boost up to 4.5 GHz depending on workload and thermal headroom. Intel manufactures the "Skylake-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 i9-9980XE 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 24.75MB of L3 cache.
18-core Skylake-X refresh Extreme Edition. Higher boost clock than the 7980XE at the same 165W TDP thanks to process refinements.
