RE[2]: This is nothing new...

in reply to "RE: This is nothing new..."
Not only that, but IBM and other big iron companies have been doing this for years, maybe decades.
There was a VAX in the 80s which could be "upgraded" by a microcode swap which, essentially, removed some no-ops put in there to deliberately slow down the machine. IBM used to do this on AS400s too...the upgrade was a hardware dongle IIRC, but I think it just told the OS to let the processor execute jobs for a greater percentage of the time (the other part being no-ops).
Anyway, is it lame? Sure!

Because for IBM mainframes you pay for licensing/usage of the CPUs. All of the mainframes come preinstalled with more CPUs than you ordered for failover and additional power when you pay. But this is in a nieche market where the buyer is well informed, not uninformed consumer market - that what makes it bad....
