Rumor: AMD's Zen 2, 7 nm Chips to Feature 10-15% IPC Uplift, Revised 8-core per CCX Design

Posted on
A submit through Chiphell makes some substantial claims on AMD's upcoming Zen 2 microarchitecture, constructed on the 7 nm course of. AMD has positively gained the core-count struggle as soon as once more (albeit with a way more decisive blow to Intel's dominance than with Bulldozer), however the IPC battle has been an uphill one in opposition to Intel's sluggish, however certain, enchancment in that space through the years. AMD did say, on the time they launched the Zen structure, that that they had a stable understanding on Zen's choke factors and its improveable bits and items - and took it to coronary heart to ship simply that.

A 10 to 15% enchancment ought to deliver AMD shut to Intel's Kaby Lake options in pure per-core, single-thread efficiency - with the chance for larger efficiency in multithreaded workloads even on the identical clocks and core counts, since AMD's SMT implementation and per-core communication appears to best that of even Intel's Espresso Lake chips. Add to that the certain clock will increase AMD will deliver to their Zen 2 components - you possibly can wager the power consumption and prime frequency advantages for the 7 nm manufacturing course of (some estimated 1.6X logic density, ~20% pace enchancment, and ~40% power discount in contrast to TSMC's 10 nm course of) will not go to waste once they can be utilized for an excellent higher efficiency uplift.

Add to that the chance -also posted through the Chiphell thread) of a per-CCX core-count enhance of 8 cores per CCX (with 16-core components being obtainable for the buyer merchandise) and a purely hypothetical declare for the efficiency crown now appears not solely believable, however seemingly.
