I'm looking to build myself a home ZFS fileserver with ECC memory.
The e3-1220L v3 has a TDP of 15 watts, compared to the e3-1230v3 with a TDP of 80 watts. These chips are, Of-course, both Haswell 22nm process. Performance wise the latter leaves the former for dead, while the former is deliberately targeted at low power tasks.
My question is - when idle - will there be significantly different power draw between the 2 cpu's? To frame the question another way - ignoring PSU inefficiencies - will there be a noticeable difference in overall power draw, assuming the tasks are not CPU bound?
Notes:
Here is a comparison of the CPU's at Intel Ark. The key differences are the number of cores (2 vs 4) and the Processor base frequency specified as 1.1GHz vs 3.3GHz (and associated turbo frequencies).
