List of Intel Pentium Pro microprocessors


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.

Pentium Pro (.35 / .50 μm)

* The 150 MHz Pentium Pro processor die used a 0.50 μm BiCMOS process.
* The 166, 180, and 200 MHz Pentium Pro processor die used a 0.35 μm CMOS process.
* The 256 KB L2 cache die used a 0.50 μm BiCMOS process.
* The 512 and 1024 KB L2 cache die used a 0.35 μm CMOS process.
* L2 cache on all models was off-die and ran at full CPU speed.
* Only the Pentium II Overdrive supports MMX.
* The Pentium II Overdrive processor is based on the 0.25 μm Pentium II Deschutes core, with the distinction that its L2 cache runs at full CPU speed, not Deschutes' half CPU speed.
