You can beat that cores per dollar handedly that if you're willing to use sufficiently odd hardware.
E.g. my Intel cluster here is mostly I have systems with 4x E7-8880v4 (22c@2.2GHz). I paid $150/chip + $450 host (thanks ebay) excluding ram.
(I have 8 such hosts now, so 704 cores)
So essentially one months cost for your AWS price w/ a 3year commit pays for an equivalent core count in systems for me... Throw in another month for the ram. Round up to another another to count for the (quite) non-trivial power usage.
You do not have to be anywhere near 100% utilization for AWS to be an extremely poor value large computing jobs compared to thrifty spending on the surplus market.

Even if you pulled these from a vendor going out of business the bit coin mining crews would suck these up in heartbeat. Where are you getting your prices?
- nullc 6y agoEbay. Hunt harder (and best offer harder). :) E7 CPUs sell absurdly cheap at times because it can be a bit hard to find compatible systems. (similarly, quad socket systems with slow or no cpus go cheap from people that don't know much about them) > ranked ram is not cheap. Yes, ram for quad socket hosts it adds up, since you need at least 2-8 dimms per socket for full memory bandwidth (which was why I explicitly pointed out that I left it out). On the plus side, those systems tend to have a lot of dimm sockets so you can use lower capacity dimms. > bit coin mining crews nah, not useful for that.
