Professional overclocker and extreme cooling products developer der8auer de-lidded a Core i9-10900K 10-core processor to study the processor’s behavior with various kinds of custom cooling setups. It was discovered that the 10-core “Comet Lake” die measures 206.1 mm² in die-area. It is 9.2 mm wide like its predecessors, “Coffee Lake” 8-core, 6-core, and 4-core, but is 22.4 mm long, with the outer edges of its packaging material barely within a couple of millimeters of the adhesion point of the integrated heatspreader (IHS). Given what we know about how much each pair of cores adds to these dies, we predict that Intel cannot elongate this die to 12 cores, without having to remove the iGPU. der8auer discovered that using liquid metal TIMs and running the processor de-lidded shaves up to 7 °C off temperatures.
