List of Intel Pentium II processors
From Wikipedia, the free encyclopedia
The Pentium II is a sixth-generation CPU from Intel targeted at the consumer market.
Desktop processors
"Klamath" (350 nm)
- All models support: MMX
- L2 cache is off-die and runs at 50% CPU speed
- Part numbers prefixed with a B are for boxed retail CPUs
