> The M1 Ultra is using the same CPU cores and GPU cores as an iPhone, just more of them. Not only that, but it's running them at basically the same clock speeds as the rest of the M1 family, and even as the iPhone. This suggests that they're running at not far above a best efficiency point, rather than way past the elbow of the voltage curve as is traditional for desktop chips.
