You'll see similar efficiency gains using modern CPUs.

My Intel Skylake quad cores from about five years ago, with total system power at 63 watts from the wall (underclocked and undervolted), can do an 80M exponent in about 3 days, or about 4.5 kWh.

However, I'm no longer running running four systems off one power supply, and now have GPUs and case fans adding to the power consumption.
