Semiconductors sometimes suffer from a rare disease where one of processor of the same series can take much more voltage than the other one. In AMD’s case, once they manufacture a wafer with cca. 200 Deneb 45 nm cores, some of them end up faulty.

Believe it or not, according to AMD testing standards TWKR doesn’t qualify as a CPU that can get under AMD warranty agreement as it's much better than it is suppose to be. This happens to one out of 200 CPUs on wafer, as we reported here.

AMD targets overclocking population and first batch of these CPUs will be for overclockers and reviewers and at some point, if the press and overclockers are happy with it, AMD might even consider to selling these CPUs.
