Leaked Slides Show Carrizo APUs Followed by Zen With 128GB/S of HBM Memory
AMD 2016 roadmap has recently leaked onto Twitter, which shows last year’s Carrizo APUs to be followed up by Zen based APU featuring stacked High Bandwidth Memory, or HBM, sometime in 2016.
The slides in the tweet come from a paper co-authored by one of AMD’s highest ranking graphics engineers, Mike Mantor. The summary slide depicts progression of the processor starting from Trinity, to Kaveri, to the current-gen Carrizo, to Zen-based APUs.
The paper reveals that a Zen APU features a next generation fully memory coherent interconnect, dubbed Onion3, which upgrades the total memory bandwidth from 8GB/s back in 2013 to 50GB/s later this year.
Further, the Zen based APU is said to come with “more CUs,” which apparently refers to larger and more capable on-board graphics engines than its predecessor. The upcoming APUs are also shown to feature HBM memory with 128GB/S of bandwidth.
AMD seems to market its newest generation APUs as “Enhancing ultra HD entertainment and gaming,” with AMD APU-powered PCs capable of handling demanding videos, and TV content at the highest resolutions. The APUs are said to “unlock the potential of Windows 10” providing robust, rich visual experiences to users.
