Ann: Commercial Hardware Acceleration Board Released, page-504

Seems they are still using Standard computer architecture as opposed to that of BRN. This seems to be the key difference as highlighted by the below pasted paragraph from the Intel article.

"Coming out of the chip giant's research lab, the new chip, dubbed the Intel Loihi test chip, consists of 128 computing cores. Each core has 1,024 artificial neurons, giving the chip a total of more than 130,000 neurons and 130 million synaptic connections."

Highlighted above. i.e. 8,16,32,64,128...512,1024

I'd say they will hit the Moores law principle limits sooner rather than later if they are using standar architecture.

I could be wrong but this is how I read it.
