AMD Just announced the brand name for Data-center CPU based on Ryzen, the brand name will be called EPYC. 
EPYC obviously is what previously known as "Naples"

APYC  series server processors based on"(Ry)Zen" x86 processing engine with up to 32 cores. Naples has 32 cores and is capable of 64 simultaneous threads, eight memory channels, supporting up to 2TB RAM per CPU and 128 PCIe 3.0 lanes. Memory can run 2400/2677 MHz per channel. The memory controller is also capable of using bigger than 16GB DIMMs and in total you could fit 4 TB of DDR4 memory. The Naples processor (well SoC) connects to whatever you need it through over a 128 high-speed I/O-lanes mostly Gen 3.

This means you could connect 4 GPU's, 12 NVMe-SSD's and some fast 10 GigE Ethernet ports to go along with it. When you couple two processors in SMT, the IO is shared though and 64 lanes will be used for the interconnect in-between the two Naples processors. Each Naples processor has four Zen based 8-core dies interconnected.

AMD has not shared more info other then announcing the branding.
