So it looks like Intel has a 72 Core Processor on the way, it connects via the PCI X16 bus, theoretically letting you have 288 Processor cores in a large tower. How this comes to mining is pretty damn obvious, CPU mining has been overshadowed for a long time and I am sure it will continue when these come out but as most of us know, Server parts become cheap second hand.
So in 5 years are we going to have 288 processor cores chugging along ?
Will this shake up the current GPU mining scene?


Here is a link to an article on it http://www.pcworld.com/article/3005414/computers/intel-plugs-72-core-supercomputing-chip-into-workstation.html

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

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

Knights Landing: 72 cores x 512 bit  x 1 to 3 operation per tick(?) x 1 GHz(?) = 37 to 110 terabitop/s
R280x: 2048 cores x 32 bit x 1 op x ~1GHz = 66 terabitop/s

Of course I gave you bad advice. Good one is way out of your price range.

Indeed. I buy used, workstation grade (with Xeon processors) computers for home. Xeon CPU are very expensive at first, but then the price fall very quickly to the point that it becomes cheaper than the consumer grade cpu equivalent.
Still using a DELL workstation with a Xeon W3540, it still have some decent power for playing video games.

Well then this could definitely be nice especially if the price degrades at the same rate as other server equipment.
