The first Zen processors are expected to arrive towards the end of this year, they will be made on a 14nm FinFET process and this new generation promises a 40 percent improvement in instructions per clock (IPC) versus current-gen AMD processors. For the server market, there will be versions with up to 32 physical cores and symmetrical multi-threading, allowing the processing of up to 64 threads.
Zen will also support PCI Express 3.0 and have a DDR4 memory controller with support for up to eight channels.
