I did. I am seeing single core geekbench scores of 2700 compared to my MacBook Air at 3500. This, for a laptop that is thicker and heavier than my air.
in my original post, i said "perf", i am not sure what you imagined, but i am not moving anything, geekbench single core score is a perfectly reasonable thing to measure under the name "perf"
In usual developer type tasks, among my friend group what I hear is that panther lake laptops are competitive with M4 laptops. But, M4s do that with a 55Wh battery, whereas most panther lake laptops come with a 70Wh battery. So if you're discussing chip performance per watt then it's probably an edge to apple silicon.
