I've got some pretty solid Ivy Macs. The MBP 9,2 I am typing this on is still super awesome. I have a 2TB SSD, 16GB ram and 11.6.2 running perfectly. This MacBook is champ and I will keep using it until it breaks. Such a shame it didn't support past 10.15 because it runs much better with macOS 11.Before this forum was launched, I argued how an early Intel Mac forum absolutely should include any Mac which natively could boot into Snow Leopard (and consequently, could also run Rosetta) — of which the Sandy Bridge i5/i7s would certainly qualify. Another reason I argued for this is Apple were still selling Core 2 Duo Macs (which automatically count as included here) alongside the Sandy Bridge Macs through 2012.
These days, probably even the Ivy Bridge Macs could be mentioned from time to time, if for no other reason beyond sharing the same form factor and parts modularity in the 13 and 15-inch 2012 unibody MacBook Pros as their Sandy Bridge and even Core 2 Duo forebears in the unibody line. A similar could be made for the 2012 Mac mini and 2012 Mac Pro, as well.
