Most of the Gflops in a phone are in the GPU - precisely because it's massively parallel, like the Cray.

Intel's i7s and Xeons have a more general purpose architecture with much less parallelism, but still manage a steady few hundred Gflops on Linpack.

True, I was speaking about the CPUs. Also GPU are still dedicated to graphical workload on smartphone, or are they used through an opencl-like lib ?

There are programming techniques where you offload all the computation onto (via OpenGL!) onto the CPU. I did this for image processing where we needed to do histogram normalization. It was not fun.

But the GFlop numbers given are maybe an order or two of magnitude off from achieved performance for something like Lapack.

Depends on the GPU. PowerVRs are remarkably general for instance.
