we used less vcore to get max speed with Lyra, for example 0.95~1 volt. But in order to get max speed in Neo, we should run at least 1060 ~1100 . ( i tesed many different types of vga) - People who could not run Lyra at max speed and less power need to tweak and waste a lot of time to figure out what optimize config to run.
I use more power in Lyra because I use higher Vcore and higher memory frequency.
You use less power in Lyra because you use lower Vcore and lower core frequency.
So maybe Lyra uses similar power as Neo.
