AMD unveils new details for its next-generation 2017 Zen CPU core

By Ina L. McManus in Software July 17, 2019

“We’re back, and just getting started.” That’s the word from AMD, which dropped some new info in a personal press event about its impending Zen structure. We’ve already had a chunk of a preview of what’s to return, was to some early benchmark leaks we suggested some weeks in the past. AMD continues to be claiming a forty% development in commands per clock for Zen, but now the employer has sincerely tested the previously introduced 8-core, sixteen-thread Summit Ridge device — and is showing it outperforming an Intel Broadwell-E processor, at the least in sure applications, at the equal clock speed.

Zen is constructed on a 14nm FinFET system and capabilities completely new branch prediction, a brand new micro-op cache, and a much broader coaching window. The employer is likewise that specialize in throughput with Zen, with 8MB L3 cache and a new cache reminiscence hierarchy.

At some stage in the equal event, AMD additionally demoed its upcoming 32-center, sixty four-thread Zen server processors, codenamed Naples, going for walks in a dual-CPU config Home windows Server, though it didn’t provide any specifics on the way it plays.

Whats New ?

New Summit Ridge computer systems will make use of AMD’s new AM4 socket, in order to be well suited with the previously named Bristol Ridge seventh generation A-Series CPUs. AM4 supports DDR4 memory; PCIe Gen three with dedicated lanes for snap shots, USB, and other I/O; SATA Express; NVMe; and USB 3.1 Gen2 at 10Gbps. Summit Ridge seems like it received’t display up until the primary region of 2017, that’s a bit of a disappointment. And there’s also nonetheless no word on transport clock speeds.

Nonetheless, the agency is happy, as nicely because it ought to be for what quantities to its largest release in the latest memory. “The overall performance and performance of our ‘Zen’ center showcases AMD at its fine,” said Dr. Lisa Su, president and CEO. “Over the past four years we have made giant investments to increase an excessive-performance, multi-era CPU roadmap as a way to electricity management products. Consumer exhilaration for ‘Zen’ keeps growing as we make sizable development towards the release of new products on the way to span from the records center to excessive-give up Desktops.”

The key here isn’t whether AMD can capture up and pass Intel in a single fell swoop, delivering today’s version of the 386-forty or the K6. Instead, at this factor, it’s a good deal greater vital Zen does well in an extensive sort of applications, along with low-energy notebooks as well as computers and servers, so that the company is well located for similarly growth and regaining lost market percentage. It looks like we’re beginning to see the muse of that for Zen, but time will tell.
