AMD details 7nm Zen 2 CPUs at Next Horizons event

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. AMD's second-generation Infinity Fabric is the bridge the connects them. With a focus on Epyc chips for servers, AMD now hopes to surpass the performance of its competitor Intel rather than just match it.

The new EPYC "Rome" processor will be one of the first to use Zen 2 CPU cores with up to 64C/128T of CPU power at its disposal.

With these "ROME" EPYC CPUs, the new architecture design also features improved branch prediction, instruction prefetch and re-optimized micro-op instruction cache, which has also been increased in size. '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.

One of AMD's mainstay features is socket compatibility for those that have already adopted previous generation processors. Nearly certainly, the Ryzen 3 family will make use of the 7nm Zen 2 architecture, which could see AMD push ahead of Intel in the raw performance and clock speed stakes, as Intel is still on the 14nm process node given it has kept pushing back the debut of 10nm-based CPUs due to problems with manufacturing them at scale.

Tesla names Robyn Denholm as chair to replace Elon Musk
Its shares soared following his comments but weeks later Mr Musk backed away from the plan, blaming feedback from shareholders. A Tesla spokesman said Ms Denholm would receive an annual cash retainer of $300,000, with $8000 in stock options annually.

What's not known is how much of the Rome DNA will make it into the consumer Ryzen 2 due early next year. All of the front-end improvements, floating point performance, and efficiencies of the 7nm process are likely to make it a mean CPU. AMD claims that it has double the throughput with the same power draw, a higher number of instructions per clock, and of course, enhanced security. "As important, on higher-threaded applications, I am expecting improved scaling with more cores". The company's official roadmap for Ryzen 2 is 2019.

Rome is currently sampling with customers now in preparation for the processors to debut in 2019. We know Lisa Su is scheduled to deliver a keynote at CES in January.

During its Next Horizon event, AMD has also taken the opportunity to release initial information regarding its upcoming datacenter-centric Epyc processors codenamed "Rome". Many expect fireworks, which the company seems to have laid out already in Rome.
