Fun fact: Bonnel Atoms (D510 etc) were not affected by the meltdown vulnerability that plagued every Pentium processor since the 1995 Pentiums. These Atoms use purely in-order execution engines which kinda makes them supercharged 486s.
Pentium were the first superscalar x86 from intel, but were still in-order. Pentium-Pro (a completely different microarchitecture) was the first OoO intel x86 microarchitecture.
