Damm... pentadeca core
Сравнивать эти процессоры между собой не совсем верно, так как они созданы для использования в разных нишах, соглашусь с Jason Borejszo
While the Extreme edition would give a better performance in a single CPU config in most cases over the E7v2, it is limited by simply being a desktop cpu. If going for an extreme workstation or server config hosting two or more E7-8890 v2 cpu's, then you will realise the true potential of all those cores shunting you to the top of the worlds elite performance ladder. NVidia Maximus rig : 4 x E7-8890 v2, 2 x TESLA, 4 x Quadro K6000 .... Would give my left ball for one of these :)
