DP83869HM: DP83869EM vs DP83869HM, die changes?

Part Number: DP83869HM
Other Parts Discussed in Thread: DP83869

Hello,

I've read the other E2E forumn posts on this topic. I want to know if there were any die changes between the EM pre-production and HM production variants of the DP83869 device or if there were simply core voltage changes to ensure performance (e.g. the 1.0 V vs 1.1 V change).

Other than the voltage change, is the silicon otherwise the exact same?

Thank you.
