The Mill is a new general-purpose high-performance processor design from out-of-the-box computing ( http://ootbcomp.com/ ). They claim to beat typical high-end out-of-order (OOO) designs like the Intel Haswell generation by crazy factors, such as being 2.3x faster while using 2.3x less power compared to a Haswell. All…
