AMD Ryzen 7 5800X3D CPU, the worlds first 3D V-Cache chip, has been delidded to achieve better thermals than the stock unit.

Twitter user, Madness7771, posted a picture of a delidded AMD Ryzen 7 5800X3D CPU. This is the first time we get to see the chiplets under its hood. As expected, the 5800X3D rocks a single CCD and a single IOD with tons of capacitors around them. Like all other Ryzen 5000 CPUs, the 5800X3D comes with a soldered design, rocks liquid metal TIM (Thermal Interface Material) & has gold plated solder which is used to transfer heat between the IHS (Integrated Heat Spreader) and the chiplets more effectively.
