Depends what you mean by 'faster' ... I wouldn't be surprised if the AGC was more responsive (faster response on the screen to user input) than a modern computer. Early computers were often quite snappy.
Considering that a modern Ryzen is 1375 times faster than a VAXstation 4000/60, and a VAXstation 4000/60 is around 1280 times faster, at least in clock, than an AGC, that would mean the M4 would need to be about 5.6 times faster than that modern Ryzen.
Hmmm... The M4 might be ten million times faster than the AGC, depending on the instructions per clock of the AGC and the VAXstation 4000/60 with which we're comparing it.
