ESP8266 performance

[FFMan]

I've used a few esp8266 modules loaded with AT command firmware in clock projects but wonder if some of my projects could be implemented directly on the esp8266 ?

How does performance of this device compare with say a 328n and how much memory is available generally ?

I haven't done any benchmarking. However, the ESP8266 runs at either 80MHz or 160MHz so you would expect it to run similar code substantially faster than a ZX-328n running at 14.7MHz.

As to memory capacity, there are different ESP8266 models but a typical memory size is 512 megabytes. However, a significant part of that is consumed by the "operating system" and networking code. Even so, for a typical application you would have far more code space available than the 30 kilobytes of the ZX-328n.
