The base load argument doesn’t hold water any more - not when there are places which are progressing towards being totally free of base load. Eg. South Australia is already nearly all renewable power with in-fill from batteries and transient gas power when needed. They’re still currently getting some base load from other states but it’s small and gradually being phased out.
That’s absolutely not true. The M3 Max just about brings Apple performance up to similar levels as Intel and AMD. The Ryzen 9 7945HX3D for example is a laptop processor which trades blows with the M3 on benchmarks - single core the M3’s slightly faster and multi core the Ryzen’s slightly faster - and in performance per watt the Ryzen’s marginally better. So really it’s just catching up with older laptop processors from other manufacturers.
And if you venure outside the laptop space to compare ultimate speed it’s nowhere near the fastest, particularly in multi-threaded. Its multi-threaded performance is around 13% of the AMD EPYC 9754 Bergamo for example.
