This is a constant core count system level performance comparison of EV7 and Montecito systems, i.e. two Alpha chips for every IPF chip.
At 64 cores the IPF system outperformed the EV7 system by 63% and cost 41% less.
At 8 cores the IPF system outperformed the EV7 system by 79% and cost 72% less.
At 4 cores the IPF system outperformed the EV7 system by 71% and cost 83% less.
The performance/price advantage of IPF over Alpha is 2.73x at 64 cores, 6.39x at 8 cores, and 10.0x at 4 cores. IPF sure looks like a huge win over Alpha (as it should be) unlike your specious claim.
