Intel's new Xeon is here, and once again it has impressive specs. The 662 mm² die supports up to eighteen cores, contains two integrated memory controllers, and comes with up to 45MB of L3 cache. We have four different SKUs to test and compare, with each other as well as with the previous generation. We've also added some new real world application testing, so join us for one of our biggest server CPU reviews ever.
