TDP is Thermal Design Power, it doesn't mean the max power.
Whilst experimenting with my new desktop, with a 65W TDP CPU, the power
of the whole system (measured at the mains supply) went from 16W idle
to 170W by executing "while : ; do : ; done" for each core. I'd guess
the bulk of that is the CPU, not the memory system.
It soon drops to 130W as the thermal protection kicks in, but you'd
want a PSU to cope with the peaks. And maxing out all cores isn't just
a theoretical exercise, transcoding video files or compiling programs
will happily do that.
