Intel® Pentium® Pro Processor

With its distinctive large gold heatspreader, the Pentium Pro remains the largest ceramic processor mass-produced by Intel.

Introduced in 1995, it’s Intel’s sixth-generation x86-based microprocessor containing 5.5 million transistors. It was mainly used in servers, high-end desktops and supercomputers like ASCI Red, and capable of both dual- and quad-processor configurations.

The Pentium Pro was released in speeds ranging from 133MHz to 200MHz.

Tcase (Maximum Case Temperature):

• Standard processors (256KB, 512KB cache): 85°C
• High-capacity processors (1MB cache): 80°C

The Pentium Pro’s large ceramic package and integrated L2 cache required careful thermal management. Most variants operated at a maximum case temperature of 85°C, while the higher-capacity 1MB cache versions ran slightly cooler at 80°C due to increased heat generation from the larger die.
