We are just starting to ramp back up here after the long holiday weekend, so let's start with something that is both interesting and easy to absorb. High-profile overclocker Der8auer has gotten his hands on an 18-core Skylake-X processor and did exactly what you would expect – delidded it.
The takeaway from this is two-fold. First, the die appears very clean, indicating that Intel has still not decided to solder these high-end processors and is going with a standard thermal interface between the die and the heat spreader.
Also…it's friggin huge. Look at the 10-core die from the Core i9-7900X that was observed earlier this year and compare it to the image above.
Though the camera angles aren't ideal, comparing the layout of the die to the physical substrate, which IS the same size between all the Skylake-X processors, you can see how much larger this 18-core die truly is. Expect to see the 18, 16, 14, and even the 12-core processors to use the same physical die.
