I'm interested in knowing which is faster, Serial communication or I2C.
So far I have the following two snippets of information that I have found while doing a bit of research.
Bit rates commonly supported include 75, 110, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200 bit/s (https://en.wikipedia.org/wiki/Serial_port#Speed)
The speed grades (standard mode: 100 kbit/s, full speed: 400 kbit/s, fast mode: 1 mbit/s, high speed: 3,2 Mbit/s) are maximum ratings. (http://www.i2c-bus.org/speed/)
So based on this information I've concluded that the fastest common bit rate used for the serial communication is 115200 bits/s. This seems to be significantly lesser than the bit rates for I2C, which appear to start at 100 kbit/s which equates to 100000 bits/s.
I'm hoping someone can just confirm that these are in fact correct. Is I2C significantly faster than serial communication?
