Wouldn't a GPU outperform a FPGA in those cases?

  It depends - for outright throughput for something the GPU is good at perhaps, but if Intel is coupling the FPGA tightly to their CPU and it has access to the memory bus and maybe some level of cache, then (I'm really speculating here) it might be very advantageous for situations where you have small chunks of data that you want to operate on with very low latency (lower latency by at least two PCIe transfers, to & from the GPU, and likely another memory transfer between the card local memory and the GPU). Then there are also likely a some set of functions you can directly implement on an FPGA that a GPU simply didn't elect to implement in its hardware or would need to compose out of a number of operations.
