Each core has a dedicated 256k level 2 cache, shares 4 MB of level 3 cache, and has an integrated memory controller (dual channel).Connectivity includes AirPort Extreme (802.11abgn), Bluetooth 4.0, Gigabit Ethernet, a Firewire 800 port, two USB 3.0 ports, a Thunderbolt port, audio inout, and an SDXC card slot.Compared to its predecessor, this model essentially is identical externally with the exception of the aforementioned USB 3.0 ports.Internally, however, it has a faster processor, architecture, graphics, and RAM.
