The chip is rated at 25 Gflops.  It will take a lot of instructions to perform a
single chess move.  25 GFlops sounds like a lot, but this document:
http://www.intel.com/software/products/mkl/techtopics/wp_mkl_benchmark.pdf
shows that a single 3.4 GHz 32 bit Intel chip can get 4 Gflops performing DGEMM.

So it is only 6 times faster than a standard CPU.  16500/6 = $2750 per chip for
break even.  Price performance is a total yawner.

I don't know what they cost.  But a fairly strong PC can be had for $1000, so
that leaves $1062.50 per card.
