AMD Ryzen Threadripper actually has 32-cores under that heatspreader

So one thing I have been thinking about for a while now is that AMDs server platform EPYC offers 32-core processors. Realistically it would not make much sense to create separate and create alternate SKUs for the consumer given AMDs recent history (4 core procs are really 8-core parts).



Well, Roman Hartung aka Der8auer just confirmed some suspicions I had in a video. He got his hands on an engineering sample Ryzen Threadripper processor, the brave man that he is delidded it (while knowing the dies are soldered to the heatspreader) and noticed four dies under there. He also killed the Threadripper that way :( That would be 8-cores per die folks! And that means in the future Threadripper could even scale upwards to 32-cores and 64-threads LOL.
 


 
Count them - 4 dies - 8 CCXes each holding 4 cores

 
We are a bit puzzled as to how things are configured for the to be released 16-core Threadripper. Common sense dictates that two dies would be disabled, then again there could be four dies active with 2 disabled cores per CCX. But ergo, Threadripper seems to be the same part that is the 32-core EPYC. And that opens up so many question like is that 1 DRAM channel per die ? :)  Likely though the processors are binned based on yiels. During fabrication one core or a die might not be properly functioning, you disable that die and if you have two dies left 100% working, you get your 16-core part. But with yields always getting better over time, i would not be surprized to see Threadripper processors in the future with more than 16 cores activated.

Check the video to get that smile on your face.
