John: Look at the 1st picture. A chip of CPU connect to a chip of RAM.
Me: OK.
John: Both of them share the same clock line and line of parallel in out.
Me: Correct.
John: So, the speed of  RAM is same as the speed of CPU.
Me: Correct.
John: Look at the 1st picture.  a and b are in CPU and c and d are in RAM. Can I say that a and b is faster than b and c?
Me: No, you can't say that.
John: In the 1st picture, a b c d use the same modulator.
Me: OK.
.
John: Now, we look at the 2nd picture. Master of spi protocol share the clock line with slave of spi protocol only.
Me: They don't share the line of parallel in out.
John (shaking head): No, they don't.
Me: Therefore, both master and slave have their own modulator.
John: Correct.
.
Me: In the case of the protocol of spi, can I say that the master is faster than the slave?
John: No, you can't say that. Because, they share the same clock line.
