Intel Core i7-8550U CPU
The Intel Core i7-8550U is a 2017 mobile processor with 4 cores, 8 threads, and integrated UHD Graphics 620.
The Intel Core i7-8550U is a quad-core mobile processor released in September 2017, based on the Kaby Lake microarchitecture. It features 8 threads via Hyper-Threading, with a base clock of 1.80 GHz and a boost clock of 4.00 GHz. The CPU has 8 MB of L3 cache and is manufactured on a 14 nm process. Its thermal design power (TDP) is 15 W, with a maximum turbo power of 25 W. The processor supports DDR4-2400 and LPDDR3-2133 memory across two channels, but does not support ECC memory. It includes integrated Intel UHD Graphics 620. The CPU is socketed in FCBGA1356 and provides 12 PCIe 3.0 lanes. It supports 64-bit, SSE4.1, SSE4.2, and AVX2 instruction sets, but the multiplier is locked. The i7-8550U was discontinued as of June 30, 2025.
