Well , IPF lacks both.It performs "good enough" , 30% better than the Alpha servers it replaces and which were developed 6 years ago.

This statement could have only have arisen out of sheer
reckless ignorance or outright lying.

Have a look at table 2 here:

http://h71028.www7.hp.com/ERC/downloads/4AA0-8802ENW.pdf

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.
