AMD demos next-generation ‘Zen’ processor core
Su says over the last four years AMD has made significant investments to develop a high-performance, multi-generation CPU roadmap.

Chip designer AMD, recently provided additional architectural details and a first look at the performance of its next-generation, high-performance "Zen" processor core.

The company demonstrated the Zen core achieving a 40% generational improvement in instructions per clock, delivering a landmark increase in processor performance.

AMD demonstrated an 8-core, 16-thread "Summit Ridge" desktop processor featuring AMD's "Zen" core, outperforming a similarly configured 8-core, 16-thread Intel "Broadwell-E" processor1 when running the multi-threaded blender rendering software with both CPUs set to the same clock speed.

AMD also conducted the first public demonstration of its upcoming 32-core, 64-thread Zen-based server processor, codenamed "Naples," in a dual processor server running the Windows Server operating system.

"The performance and efficiency of our Zen core showcases AMD at its best," said Dr. Lisa Su, president and CEO of AMD. "Over the last four years we have made significant investments to develop a high-performance, multi-generation CPU roadmap that will power leadership products. Customer excitement for Zen continues to grow as we make significant progress towards the launch of new products that will span from the data centre to high-end PCs."

The Zen processor core features multiple architectural advances designed to increase the performance, throughput, and efficiency of AMD's future products.

Mark Papermaster, senior vice president and chief technology officer at AMD, said: "An engineer may get one chance in their career to work on a project of this size and scope, and maybe never one with as much potential to impact the future as much as Zen."

Papermaster added that: "With Zen, we aim to do what many never thought possible - deliver a 40% generational improvement in instructions per clock while maintaining power requirements in line with our previous generation technology.2"

"AMD invested where it counts, with an x86 core that can scale from PCs to high-performance servers," said Linley Gwennap, principal analyst, Linley Group. "Consumers today expect to get the most out of their systems to create transformative experiences. The versatile design of ‘Zen' delivers highly-efficient performance that should provide increased computing capabilities across the spectrum - from devices to cloud computing."

Expected to launch first, the Zen-based Summit Ridge desktops will utilise the AMD AM4 socket, a new unified socket infrastructure that is compatible with seventh generation AMD A-Series desktop processors, previously codenamed "Bristol Ridge".
