AMD targets Xeon CPU with Zen-based Naples

AMD configured two dual-socket test systems for a live demonstration, one based was on AMD Naples and the other on Broadwell-E.

Naples is AMD's codename for its new 32-core System-on-Chip (SoC) silicon designed for the server market, and the supplied benchmarks suggest that Intel is once again on the back foot.

AMD Naples comes with up to 32 cores and 64 threads as well as an 8 channel memory interface and a maximum of 2TB DDR4-2667 memory. SMT-enabled (simultaneous multi-threading) cores provide 64 threads, a total of eight DDR4 memory channels pave the way for massive memory bandwidth, and 128 PCIe 3.0 lanes deliver high-speed I/O without the need for an additional chipset.

Just like its Ryzen CPUs are taking on their Intel counterparts in what's being seen as a potential game changer in the desktop CPU segment, AMD's Naples chips are also optimized to lock horns with Intel's Xeon processors and improve its stake in the server market. While each Naples CPU will support 128 individual PCIe lanes, in a dual-socket configuration, 64 lanes from each CPU are reserved as a communication bus between the processors through AMD's Infinity Fabric.

Jewish Institutions Face Another Wave of Bomb Threats
Neil Corrigan says a major intersection was shut down while police investigated the threat and a school was locked down. He said the latest incidents were the sixth wave this year, amounting to 140 bomb threats; each seemed different.

He says Intel's Xeon E5-2699A v4 processor has up to 22 CPU cores.

AMD's current figures show Naples with a 45 percent core advantage over the Intel E5-2699A V4. In its demos, AMD used a seismic analysis workload, which involved multiple iterations of 3D wave equations.

"Today marks the first major milestone in AMD re-asserting its position as an innovator in the datacenter and returning choice to customers in high-performance server CPUs", said Forrest Norrod, senior vice president and general manager, Enterprise, Embedded and Semi-Custom business unit, AMD. This groundbreaking system-on-chip delivers the unique high-performance features required to address highly virtualised environments, massive data sets and new, emerging workloads. The first processors are scheduled to be available in Q2 2017, with volume availability building in the second half of the year through OEM and channel partners.
