AMD in its Computex 2018 address earlier today, mention that its second-generation EPYC enterprise processors will be based on its 7 nanometer "Zen 2" architecture, and not 12 nm "Zen+." The company has the 7 nm silicon ready in its labs, and will begin sampling within the second half of 2018. The first products could launch in 2019, after validations. Besides improved energy-efficiency, the 12 nm "Zen+" architecture features a minor 3-5 percent IPC uplift thanks to improved multi-core clock-speed boosting, and faster caches. "Zen 2," on the other hand, presents AMD with the opportunity to make major design changes to its silicon to achieve higher IPC uplifts. The 7 nm process introduces significant transistor density uplifts over the current process. AMD is in the process of building 4-die multi-chip modules using the 12 nm "Pinnacle Ridge" silicon for its 2nd generation Ryzen Threadripper HEDT client processor family.
