“AMD moved towards the 7nm fabrication node completely and is reaping the fruits of that node; Intel has a tough time breaking away from 14nm. Initially, they wanted to move to 10nm, but that has proven impossible for various reasons. Something had to change, though, and for Intel, that had to be its architecture. For the laptop parts, there’s tiger lake on 10nm, with Golden Cove CPU cores. Here’s what Intel did, they took these CPU cores (which offer more IPC) and reversed engineered them back (ported if you will) towards 14nm. And that my friends are what is now called Cypress cove cores, the cores that Rocket-Lake-S series processors now use. So while they gain the generational performance increase in IPC, they however still have to face the fact that they’re on 14nm, and that means high voltages, high (and hungry) clock frequencies, and thus energy efficiency is getting a thing on its own. ”
