Nope, it's the same M1 for both, same voltage/frequency curves and top clocks. It's the whole point of having a chip that's named the same. '
No modern laptop CPU has a headline power use number. They all try to use the headroom that they've been given.
Cinebench is very far from being the end-all of benchmarking that you say it is here. And there are far more optimised renderers around if you want to benchmark that. (RTX makes the matter moot nowadays anyway)
It does not use AVX-512, or older AVX levels much for that matter, for a workload that is SIMD-friendly. For Arm, they leave lots of perf on the table too. (Cinebench uses Intel's Embree renderer, with AVX-512 disabled)
Geekbench 5 is designed to be a composite index of multiple benchmarks to be more realistic to some extent than using just one. You can also access to the scores of the subtests too.
Geekbench in general has very heavily biased for ARM as it does not run the same code on both. Cinebench doesn't have this issue. And while yes nowadays a lot of rendering is done on GPUs for C4D the class of programs is path-tracers and they are often ran on CPUs for many scenes.
