AMD said on Tuesday it's going to roll out a 7nm 64-core second-generation Epyc server processor, dubbed Rome, in 2019.
Samples of the processor are in the hands of selected organizations for testing and evaluation. This comes a day after Intel promised on Monday a 14nm 48-core Cascade Lake AP Xeon chip also for 2019.
AMD - Rome - PCIe - Interfaces - Infinity
AMD's Rome will sport PCIe 4.0 interfaces, and the usual PCIe-based Infinity Fabric that interconnects processor sockets and any GPU accelerators. With up to 64 physical Zen 2 CPU cores, the chips can run up to 128 hardware threads. This is double the number of cores and hardware threads as 2017's 14nm first-generation Zen 1 Epyc, dubbed Naples.
As such, AMD CEO Lisa Su told journos and industry analysts in San Francisco on Tuesday that Rome will have double the performance of Naples, due to this core count leap and switch to 7nm.
X64 - Core - Count - Intel - Xeon
The physical x64 core count blows away Intel's Xeon compute family, which only just set itself a high-water mark of 48 cores with Cascade Lake AP. Also, that line is still on Intel's 14nm process, whereas AMD is nudging ahead with TSMC's 7nm. AMD also claimed a single-socket Rome can match or outperform a dual-socket Intel Xeon Scalable 8180M setup, when running the ray-tracing C-Ray...
