I'm not convinced AMD will match Intel's peak clock speeds and I'm also not convinced they'll even want to. Intel have to basically throw efficiency out the window to reach the clock speeds they use now (hence relatively low base clocks on their 65 W parts and generally large gaps between base and boost clocks), similar to what AMD had to do with the R7 2700X. If AMD do get an IPC advantage and a core count advantage at every price point then they don't even need to match Intel on clock speed, especially since all their chips are unlocked anyway. They would potentially claim a multithreaded performance win, a single threaded performance tie, and an efficiency win at various price points, and then still offer more overclocking headroom and market that towards gamers.I suspect the next iteration from AMD will significantly overtake intel in IPC - well by 5 -10% but that significant for intel! - and at least match intel in clock speed.
Not good times for the blue team in 2019.
