The problem with this question is that it a variable point in time comparison. Although the speed of the Apollo computers is fixed, smartphones change constantly.
Here is an excerpt from a good article about the Apollo computer speed:
The IBM PC XT also ran at a dizzying clock speed of 4.077MHz. That's 0.004077 GHz. The Apollo's Guidance Computer was a snail-like 1.024 MHz in comparison, and it's external signaling was half that -- actually measured in Hz (1/1000th of 1 MHz, much as 1 MHz is 1/1000 of 1 GHz).
