List of Intel Pentium Pro microprocessors

The Pentium Pro from Intel is the first of their sixth-generation CPUs targeted at the consumer and server markets. The processor was relatively unusual in that the Pentium Pro used a unique "on-package cache" arrangement; the processor and the cache were on separate dies in the same package and were connected closely by a full-speed bus. The dies had to be bonded together early in the production process, before testing was possible. This meant that a single, tiny flaw in either die made it necessary to discard the entire assembly, which was one of the reasons for the Pentium Pro's relatively low production yield and high cost.
