> If that's remotely true, and their product offer/lineup is built around the failure rates, single-core CPUs would have resulted in staggering numbers of failures, since a single defective core meant a trashcan rather than a down-SKU. I don't think all defective chips were DOA. A core that is stable at 1000MHz would be a Pentium 4 and another sample of the exact same chip that catches fire at 1000MHz but is stable at 500MHz would be a Celeron (etc).
