It looks like Roman "der8auer" is in love with delidding CPUs. Bringing out the razor blades and soldering heat gun he's very carefully removed the heatspreader from a Rzyen Threadripper CPU and what's underneath is interesting to see. According to his pictures, Ryzen Threadripper is based on four actual dies and there are no dummy dies or just spacers underneath the heatspreader.


Since Threadripper is basically a scaled down version of EPYC it was pretty much expected to see four actual dies, but nevertheless it’s interesting to see a visual confirmation. According to der8aur's pics, there aren't any dummy dies or structural inserts inside Ryzen Threadripper CPUs. The images from "der8auer" show, AMD is soldering the heatspreader to the four die MCM (Multi Chip Module) and for that purpose they're using indium solder and gold contacts to optimize the heat transfer.

These extra and possibly locked dies sport real silicon with transistors and integrated circuits. According to Roman, they are just not enabled or fully functional. Since AMD has a long history of "unlockable" chips, the guesswork would be that all those dies could actually work. In other words, AMD might have the possibility to launch 32-core Ryzen Threadripper CPUs. Right now this wouldn’t make any sense since those chips would directly compete with the manufacturer’s EPYC line.
