Intel’s next desktop generation, Nova Lake, is already picking up some spicy numbers, and this time it is not a benchmark screenshot. Leaker kopite7kimi claims that the top Nova Lake desktop processor could be configured with a Power Level 4 limit above 700 watts.
Your processor is fully configurable. Set it to whatever TDP you want; the lower you go, the more efficient it gets.
This is why AMD’s X3D chips are perceived as efficient. They aren’t actually that much more power efficient, but they’re configured to stay out of absolutely crazy voltage/clock zones most processors boost to. Cap a regular AM5 chip to the same power level, and it’s pure task efficiency wouldn’t be too far off.
