Which is what Zen will do later this year, bring performance parity with Intel due to a 40% IPC improvement.
Apparently you have not followed AMD's activities in recent years. They have developed a completely new CPU architecture known as "Zen". The first Zen based desktop CPUs are named Summit Ridge and are scheduled to be shipping in Q4 of '16. AMD was well aware four years ago that they needed to make a significant performance step to bring better performance to AMD customers. Zen based products will be released for consumer and enterprise thru 2017. AMD engineering is already working on "Zen Plus" which will follow the release of Zen products by a year or two and bring even more performance. AMD plans to stay competitive in the X86 CPU market for years to come.
