Intel announced its latest 8th generation Core processors today, and is promising that the new chips will offer up to a 40 percent speed boost over the previous 7th generation Kaby Lake chips.

The 8th generation chips will be doing things a little differently from other generations. In the past, Intel has either used generational steps for introducing new chip architectures (say, the jump from 22nm to 14nm between Haswell and Broadwell) or to offer an improved version of the previous generation’s architecture (like Skylake, which was an upgraded version of the 14nm node).
