AMD prepares for IPC race with Intel

In May 2015, we reported that AMD’s first Zen CPUs, launching in Q4 2016, would most likely be quad-core chips based on a presentation slide showing the company’s Zen core units scaling up to four cores with shared L3 cache. According to new information released one year later, this may not be the case and, the company could be preparing to launch eight and six-core variants in a tight efficiency race against Intel's 'Kaby Lake' CPUs.
