The verdict

The A 2025 flagship phone has 1 million× the memory of the Atari 800 and a clock 1,676× faster.

They are 46 years apart. Doubling every two years (Moore's law) would predict about 8.4 million×; the memory actually grew slower than that. Across the whole catalogue memory doubled every 1.9 years.
