AMD explains dummy dies in Threadripper CPUs

by on19 September 2017


Dies are there but can't be enabled

There has been a lot of noise generated regarding the recent discovery that AMD Threadripper CPUs actually have four dies and not two dies and two "substrates" as it was originally believed but, according to AMD's James Prior, these are inactive dies and there is no way to enable them.

The discovery that AMD Threadripper actually has four dies, just as the EPYC CPU, came when der8auer managed to delid the CPU and discover that there are actually four dies under the IHS.

While there were plenty of rumors floating around and a vague possibility that these can be enabled, James Prior, AMD's Senior Product Manager, went public on Twitter, saying that the two dies in question are indeed dies but use a different substrate and have no path to the operation, describing them as "basically rocks".

While this means that these are not dummy dies, at least not theoretically, AMD moved to describe them as dummy instead of inactive just to break away from all the drama and confirm that they can't be enabled in any way.

Hopefully, this will put an end to all the rumors as if there was a way, we are sure that someone would have managed to make it work by now.
