The MacBook Pro on which I’m writing this piece needs memory that can keep up with a powerful processor running many programs at once: so it uses a standard called DDR, “double data rate,” which runs at a reasonably high voltage and offers high bandwidth. The processor on my iPhone is less powerful, so it needs less data at any given moment; but voltage matters enormously, since every milliwatt allocated to memory is drained from the battery. So smartphones use LPDDR, “low-power double data rate,” a variant of DDR engineered to operate at lower voltages.
The last MacBook Pro to use DDR was in 2019. All Apple Silicon Macs use LPDDR.

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.

They were still using LPDDR3 because LPDDR4 wasn't ready for production yet (despite regular DDR4 being available). The 2018 MacBook Pro's finally switched to LPDDR4.
- fredoralive 5mo agoThe early 2005 PowerBook G4 was the last pro notebook with DDR surely, as the MacBook Pro your referring to seems to use DDR4.
