It’s misleading, but not wrong based on the hardware…

• i3-6100U - 2015, 15W TDP base speed 2.3Ghz (has no turbo), 3MB cache

• Ultra 5 125U - 2023, 15W base TDP, base speed 1.3Ghz, turbo 4.2Ghz(57W), 12mb cache.

Honestly I’m surprised they didn’t go for the Ultra 9, with a 2.3(45W) base and 5.1 tubo(115W) and 24MB cache.
