Intel will be calling its next CPU, code-named Klamath, the "Pentium II" when it is released in early May. The Pentium II is a Pentium Pro CPU with multimedia extensions, called MMX, built-in. Previously, only Intel's latest Pentium CPUs benefited from MMX capabilities.
Intel recently demonstrated a Pentium II running at 400 Mhz. The first versions of the CPU will run at 233 and 266 Mhz, however. Intel is targeting the high-end corporate market originally. The Pentium Pro and Pentium MMX CPUs round out Intel's line of x86-compatible chips
