AMD X390 and X399 chipset info leaks: Quad-channel, 128-lane PCIe 3.0 and more!
AMD released info about its Naples CPUs a few days ago, though AMD was conveniently sketchy about vital information. The recent leaks for the upcoming chipsets modeled X399 for ‘RZ4700’ Naples CPUs with dual sockets and X390 for RZ2700 Naples CPU with a single socket. The information that AMD revealed about Naples features are as follows:
Preview of Naples Server CPU
- A highly scalable, 32-core System on Chip (SoC) design, with support for two high-performance threads per core
- Industry-leading memory bandwidth, with 8-channels of memory per “Naples” device. In a 2-socket server, support for up to 32 DIMMS of DDR4 on 16 memory channels, delivering up to 4 terabytes of total memory capacity.
- The processor is a complete SoC with fully integrated, high-speed I/O supporting 128 lanes of PCIe® 34, negating the need for a separate chipset
- A highly-optimized cache structure for high-performance, energy efficient compute
- AMD Infinity Fabric coherent interconnect for two “Naples” CPUs in a 2-socket system
- Dedicated security hardware
About the X399 Chipset- dual sockets and more!
The diagram above reveals multiple PCIe lanes from the chipset and processor dedicated for specific functions. 16 lanes are provided for the dual 10GbE connectors, 8+4 for SSD, eight dual-channel memory controllers. Four PCIe lanes are provided for other functions such as I/O, USB 2.0, 3.0, 3.1 and eSATA interface, along with 2Gb ethernet, onboard GPU and TPM module. Based on this information, its made for data centers and other enterprise-level users.
About the X390 Chipset- Aimed towards professionals and high-end users?
The single socket RZ2700 variant paired with X390 chipset seem to provide more features. It has quad-channel support along with maximum support for 256GB ECC DDR4-2666. It provides 48 PCIe 3.0 lanes. The chipset uses four of them and the rest used by its dual 10GbE, M.2, PCIe, USB controllers, EPU, TPM and 7.1 audio. 16-Lane PCIe 2.0 lanes are for its eSATA, dual-GbE, Firewire A x2 and B x1, SGPIO, 6x SATA III ports and U.2. It also provides bandwidth to a PCIe x1 and a PCIe x16 slot in x4 mode. Most likely, this chipset will require e-ATX form factor to take advantage of X390’s native features.
The X390 diagram comes with a motherboard layout example resembling Intel X99 platform. All four PCIe x16 slots have x16 bandwidth, eight four-pin fan headers, 1 U.2 connector, front panel USB 3.1 and dual Intel Ethernet. The AURA RGB controller is on the motherboard diagram. Its highly likely this will be aimed towards high-end system users. Most likely motherboard vendors are on standby for its release.
Head-to-Head with Intel at last?
As AMD revealed Naples and the presence of a motherboard vendor’s exclusive RGB controller on the diagram provides a benefit of the doubt. Users wondered if AMD has anything for high-end and enterprise level users. It seems AMD is ready to reveal all its arsenal for varying users.
