> The Geekbench scores cannot compare laptop CPUs with desktop CPUs, because the tasks that are executed are too short and they do not demonstrate the steady-state throughput of the CPUs. The desktop CPUs are much faster for multithreaded tasks in comparison with laptop/tablet CPUs than it appears in the GB results.

Bullshit. What you're talking about is the steady-state of the heatsink, not the steady state of the chip. Intel learned the hard way that a fast CPU core in a phone really does become a fast CPU core in a laptop or desktop when given a better cooling solution.

> However in multithreaded execution, where the power consumption of the CPU reaches the power limit, the number of logic transitions per second in the same manufacturing process is determined by the power consumption. Therefore the benchmark will be completed in approximately the same number of seconds when the power limits are the same, regardless of the differences in the single-threaded performance.

No, microarchitecture really does matter. And so does the macro architecture of AMD's desktop chips that burn a huge amount of power on an inefficient chip to chip interface.
