AMD unveils 7nm Zen 2 microarchitecture for its future family of processors

AMD EPYC 'Rome': Zen 2 on 7nm, 64C/128T of CPU power AMD shows Zen 2-based 7nm EPYC Rome CPU in action

AMD's latest "Rome" CPU features a basic chiplet design with the 7nm execution cores connected to a 14nm IO chip via faster Infinity Fabric. When matched against a dual-socket Xeon Platinum 8180M server, the AMD box ran the benchmark to completion first. To address this Zen 2 will use CPU chiplets that house the actual computational cores, and these then connect to a single I/O die, which would handle the connection to the RAM and other devices. According to AMD, these new chips will bring twice the performance and four times the floating-point power per socket compared to the current-generation EPYC chips. This offers not only higher IPCs and a significant increase in overall performance, but also improved security features in the recently announced EPYC CPU "Rome". Since Zen 4 microarchitecture is still in design phase, chances are that processors on its base will be made using a more advanced node, so think 5 nm, but keep in mind that any guesses today are speculations at best. 'Combining world-class performance and a flexible architecture with a robust software platform and the industry's leading-edge ROCm open software ecosystem, the new AMD Radeon Instinct accelerators provide the critical components needed to solve the most hard cloud computing challenges today and into the future.

What's not known is how much of the Rome DNA will make it into the consumer Ryzen 2 due early next year.

Man United to take momentum into Manchester derby
Massimiliano Allegri chose to give Alex Sandro and Giorgio Chiellini a game off, saving them for Wednesday's game against United . Paul Pogba claims to be "happy" at Manchester United but has stopped short of ruling out a future return to Juventus .

As ArsTechnica explains it, Zen 2 has a combination of 14nm and 7nm components under its hood. Performance gains in terms of instructions per clock will be improved as well.

"It's hard to say on notebooks right now and I need a bit more information on how AMD would implement this in mobile platforms", he said. The company's official roadmap for Ryzen 2 is 2019. The cost savings are driven by the core density of AMD EPYC processors that offer M5 and T3 instance customers a balance of compute, memory, and networking resources for web and application servers, backend servers for enterprise applications, and test/development environments with seamless application migration. We know Lisa Su is scheduled to deliver a keynote at CES in January. During the event, AMD announced a pair of 7nm Vega cards for professionals, which you can read about here, and provided the first real details on its upcoming Zen 2 architecture highlighted by a 64-core/128-thread Epyc processor codenamed Rome.
