Quite possible. He did say his “powerful” MacBook Pro CPU is faster than his iPhone.

I’m pretty sure even an iPhone 11 chip is more powerful than a 2019 MacBook Pro CPU in ST. An iPhone 15 is more powerful than the fastest 2019 MacBook Pro Intel CPU in MT.

I suppose he can be using a 2019 MacBook Pro or older and an iPhone 14 or older and compares only MT speeds.
