Intel Mobile Pentium 4-M

Intel Mobile Pentium 4-M The Intel Mobile Pentium 4-M is the low-power version of the Mobile Pentium 4. It is built on the NetBurst architecure, which is optimized for achieving performance through high clock speeds. The Mobile P4-M uses the Northwood core. Features 1.2 - 2.6 GHz clock speed 400 MHz FSB 55 Million Transistors 0.13 µm fabrication process 0.07 µm gates 1.30/1.20 VCore 8 KB L1 D-Cache, 12k uOps L1 trace cache 512 KB L2-Cache Enhanced SpeedStep, QuickStart, Deeper Sleep MMX, SSE, SSE2 instruction sets Note: This processor had efficiency problems, so Intel switched back to using the Tualatin architecture, releasing the Intel Pentium M (Banias) next.
