And note that it's not that hard. Google, who are not really known as a chip company, designed the TPUs: The result is called a Tensor Processing Unit (TPU), a custom ASIC we built specifically for machine learning — and tailored for TensorFlow. We’ve been running TPUs inside our data centers for more than a year, and have found them to deliver an order of magnitude better-optimized performance per watt for machine learning. This is roughly equivalent to fast-forwarding technology about seven years into the future (three generations of Moore’s Law).

That sounds like a custom ASIC for this purpose. And if Google can do it, so can Intel.
