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.
