VideoCardz noticed that the latest version of the HWiNFO tool added support for the future AMD’s Ellesmere, Baffin and Greenland GPUs. I wasn't sure about posting it because it's unknown if HWiNFO is just following the trend or received details from AMD, but here it goes:
Greenland is believed to the fastest GPU equipped with HBM2 and built in FinFET manufacturing process. As for the Baffin and Ellesmere, we are not sure. Koduri only told us about two GPUs, so Baffin and Ellesmere could be the same thing, only one equipped with HBM and the other with GDDR5X (just a theory). Or maybe there is more than just Polaris10 and 11, but Koduri was just not ready to share such information.
