The Pentuim line of processors is binary compatible with older generations of x86 processors and has the following enhancements over the previous generation of x86 processors (80486):
  • Branch prediction.
  • Dual processor support.
  • Superscalar architecture (2 pipelined integer units + 1 pipelined FPU).
  • FPU performance enhancements.
  • Power management features.
  • Separate 8 KB code and 8 KB data cache.
  • 3.3V core and input/output level.

Production microprocessors

Intel Pentium 60 - A80501-60
60 MHz
273-pin ceramic Pin Grid Array

Pentium 60 MHz microprocessor was the first from Pentium series, and it was the slowest one. The CPU was shipped in pin grid array package similar to 80486 - the CPU bottom side looked like a bigger version of 80486. Like older 80486 processors, the Pentium 60 required 5 Volt. High core voltage and big die size were the primary reasons of the processor running very hot even with factory supplied heatsink. Short term fix for this problem was adding an integrated heatspreader that helped to dissipate the heat (see other pictures). The heat problem was solved in the next generation of Pentium chips by switching from 0.8 micron to 0.6 micron manufacturing process, and reducing core voltage to 3.3 Volt.

273-pin ceramic Pin Grid Array with heatspreader

Boxed Pentium 60 processors (and 66 MHz processors for that matter) had different naming convention. Their name had a standard prefix "PCPU", which means "Pentium CPU", followed by core voltage identifier "5V" (for 5 Volt parts) or "3V" (for 3.3 Volt parts) and CPU speed in megahertz. There were not as many boxed Pentium 60 processors as OEM processors manufactured, this is why they are much more difficult to find these days.
Intel Pentium 66 - A80501-66
66 MHz
273-pin ceramic Pin Grid Array

Pentium 66 was introduced at the same time as Pentium 60 - in March of 1993. The CPU had the same 1x clock multiplier as the 60 MHz part, but was slightly faster due to faster front side bus. To make the processor more stable at higher frequency Intel increased core voltage from 5V to 5.25V. As a direct result of this, the processor ran even hotter than Pentium 60.
