8th Gen Intel Core i5 8250U Review

The 8th Gen Intel Core i5 8250U is a 4-core, 8-thread ultraportable processor built on Kaby Lake Refresh, running a 1.6 GHz base clock that boosts to 3.4 GHz.

As one of Intel's first ultraportable chips to bring genuine 4-core capability to the U-series tier, this processor represented a real generational leap over the previous 2-core 7th Gen chips.

Intel UHD Graphics 620

A basic integrated GPU intended for display output and light everyday use, adequate for productivity and media consumption but not gaming.

How Is the Core i5 8250U in Terms of Performance

The genuine jump to 4 cores from the previous generation's 2-core U-series chips gave this processor real multi-threaded gains at launch, a meaningful step up for mainstream thin-and-light laptops.

Benchmarks

Cinebench R20 multi-core scores of 1,199 and single-core scores of 346 reflect solid performance for one of Intel's first genuine 4-core ultraportable chips, a real generational improvement over 7th Gen's 2-core ceiling.
