List of Intel Pentium II microprocessors

Desktop processors

"Klamath"">Klamath (microprocessor)">"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

  "Deschutes"">Deschutes (microprocessor)">"Deschutes" (250 nm)

• All models support: MMX
• L2 cache is off-die and runs at 50% CPU speed
• The Pentium II OverDrive is a Deschutes Pentium II core packaged for Socket 8 operation. It comes with 512 KiB of off-die full-speed L2 cache, which makes it very similar to the Pentium II Xeon.
