List of Intel Pentium II processors

The Pentium II is a sixth-generation CPU from Intel targeted at the consumer market.

"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" (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 KB of off-die full-speed L2 cache, which makes it very similar to the Pentium II Xeon.

"Tonga" (250 nm)

 * All models support: MMX
 * L2 cache is off-die and runs at 50% CPU speed

"Dixon" (250 or 180 nm)

 * All models support: MMX
 * L2 cache is on-die and runs at 100% CPU speed
 * Also known as Pentium II "Performance Enhanced"
 * mqbA1 stepping is actually at 180 nm 27.4 million transistors die size 180 mm2
