If the update reduces the performance of the device it would not be performing as advertised.How is a microcode update changing the description of the product? They aren't making limits to what they had described the product as, they are actually rectifying (with the microcode update) a mistake that caused the product to operate out of its original description.
Now this error may very well impinge on the quality of the processor, but 1) You have to prove this, and 2) Is this impingement on quality such that the processor will behave unacceptably within the 5 or 6 year consumer warranty period? If so, then under UK law they'll have to replace it or refund the purchase. If not, then tough.

Second, the proof is in the current events, Intel have sold a faulty product. It is aging prematurely. The fault may or may not be evident in any given processor today. The bandaid… oops, microcode update may stop the accelerated aging and return it to a more normal rate.. who knows.
I don’t have a dog in this fight, I hope that all those who do are treated with due respect by Intel. They trusted that Intel would sell a piece of kit that wouldn’t die or have an elevated risk of popping its mortal coil within the warranty period (replacement no problem) or just after.
This has been going on for months, Intel have deflected, blamed partners and been found to be responsible. They have finally admitted the fault in the cpu and hopefully the August patch will arrest the aging.
