Intel · Core i7 · 2019 · FCBGA1528
The Intel Core i7-8557U is a mobile (laptop) processor with 4 cores, released in 2019. It is part of the Core i7 lineup, using the 8th Gen platform, and uses the FCBGA1528 package, which is soldered to the laptop's motherboard rather than socketed. Internally, it is built on the "Coffee Lake-U" 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 i7-8557U has a base clock of 1.7 GHz and can boost up to 4.5 GHz depending on workload and thermal headroom. Intel manufactures the "Coffee Lake-U" silicon on a 14 nm process node. This processor supports DDR4/LPDDR3 memory. With a base TDP of 15W the Core i7-8557U is an ultra-low-power design aimed at thin-and-light laptops. Integrated graphics are provided by the Iris Plus Graphics 645 solution, so a discrete GPU is not required for display output. The cache hierarchy includes 8MB of L3 cache.
