Naples is an up to 32-core, 64-thread variant of Zen, targeted at enterprise and data centres.
AMD said that Naples processors will feature eight-channel DDR4 memory controllers (with up to 16 DIMMs attached per CPU), with support for up to 4TB of memory and 128 lanes of on-chip PCI Express connectivity.
All this will be in a dual processor/dual socket configuration, which gives Naples up to 64 physical cores (128 threads), access to 32 DIMM slots, and aggregate 16 memory channels. This is double the memory channels, higher memory and more cores than a similar Intel Xeon E5-2699A V4 based server.
AMD’s performance comparisons at its tech day event pit a 2P Naples server with 512GB of DDR4 RAM up against a 2P Intel Xeon E4-2699A V4 configuration with 384GB of RAM.
The Naples system had a higher memory capacity and that memory was clocked much higher too — 2400MHz versus 1866MHz. The Naples system has more cores, and with SMT on, can ultimately process more threads.
The AMD Naples system also has double the memory channels, further improving peak memory bandwidth. In its demos, AMD used a seismic analysis workload, which involved multiple iterations of 3D wave equations.
The only thing that AMD didn’t provide were the prices, but it did say that they should be in the shops in Q2 this year.
