Nah, GPUs have thousands of streaming processors and are better suited for hashing except for maybe a couple of algos.
And I'd imagine this thing will cost a fortune compared to GPUs.
Like I was saying that server equipment is cheap after a couple years, just look at the prices of used xeon processors that are just a couple years old but you're right gpus will probably still blow these out of the water for MOST algorithms.
Well the Cryptonight algo. comes to mind (Monero, Bytecoin, etc) where the main bottleneck is memory speed (in CPUs it would be the L3 cache, GPUs it would be GDDR5). The memory that the intel PCI card has seems to be around twice as fast as your typical set of GDDR5
Knights Landing ... providing up to 500GB/sec of memory bandwidth
in which case depending on the price of the thing, it should be more effective at mining this algo than GPUs. When compared to full CPUs it's a different story because GDDR5 memory is slower than the CPU L3 cache and doesn't have as good random access speed.
However if you make a miner for this intel PCI card you could have a bunch of concurrent instances of the miner which sounds like it would crush through (Plenty of cores to have multiple instances of the miner + memory twice as fast as your typical GPU). No way of telling until someone tests it though. Also someone needs to make a miner for the thing before anything
