Is it much cheaper than GPGPU-capable GPU (from nVidia or AMD)?

I wonder if software and tools developed for Tilera64 etc. platforms can be easily ported to Epiphany board...

At 14 cents per kilowatt hour, it would cost me $6.13 to leave one of these things calculating for a full year. Some graphics cards average well more than 100 watts. 100 watts for a year is $122.64.

On the other hand, it is also slower and has much less RAM than those high power GPGPU-capable GPUs. Each core on a GPU is like a SIMD processor, and does certain classes of operations much much faster than this thing. Each core on these guys is like a little general purpose computer, without enough RAM to run Linux.
