The cpu processes tasks in memory. RAM is just part of the memory. So when it processes lots of data, that data will likely get loaded into RAM so it is ready for the cpu, this is to speed things up because ram is faster to access than storage devices. So cpu usage & ram may correlate, but don’t have to. May be in some cases like core 2 series, the cpu cache speed is the same as the cpu core speed. It is noted that, cpu cache is such kind of cache used by the central processing unit of a comp to reduce the average time to access memory while ram is a type of computer data storage (temporarily).
