R430 in 2015 are based on Xeon E5-2600 v3 [1], based on 22 nm Haswell up to 18 Core, 36 vCPU Cores for RSP of $4115. For the same RSP today you could get 112 Core / vCPU from Intel [2] Intel Xeon 6746E Processor. Considering IPC and real core vs Thread I expect may be 2x difference in Core to Core comparison. That makes it only 6x difference over 10 years. Less than what I expected.
