When famed overclocker der8baurer "delidded" AMD's highly anticipated Ryzen Threadripper in a video posted on Thursday, he got a surprise and spawned a mystery: Did AMD really waste two perfectly good 8-core chips to build Threadripper? So did AMD really waste two perfectly good "Zeppelin" dies? Rather than a single monolithic die, like Intel uses on its Core i9, AMD builds its Ryzen and Ryzen Threadripper CPUs using multiple chips connected with a high-speed fabric. The plastic plate is approximately the size of Intel's new Core i9 chip.
