Which is faster, P4 - 3.2 Ghz or PM - 1.6 Ghz?
Question:
Intel® Pentium® M 725
Intel® 855GME chipset
shared 64Mb Video setup
1.6GHz / 400MHz / 2Mb L2 cache
256Mb DDR-SDRAM
60Gb Mobile HDD
Laptop 2:
Mobile Intel® Pentium® 4 3.20A GHz
• 512Mb DDR 333 SDRAM
• 15.4in. WXGA LCD Screen
• Embedded SiS M661FX, shared memory: 32Mb to 64Mb
• 40Gb HDD with Ultra DMA 100
Which laptop is faster?
Answer:
Your spec are incomplete (for example, what type of DDR RAM and hard drive in laptop 1) but from what you've given it's laptop 2.
hi there
laptop 2 is faster.
Pentium M (Mobile) was designed for laptops, and loses some performace for power saving. P4 was desigined for full performance. You also get more RAM, which will help
2nd one is better:
Here is a website that goes into details on comparisons of the two:

Pet M:
# Features & Benefits: Power Optimized 533/400 MHz processor system bus, Micro-ops Fusion & Dedicated Stack Manager: Allows faster execution of instructions at lower power.
# Support for enhanced Intel SpeedStep Technology w/ multiple voltage & frequency operating points: Allows for better match of performance to application demand.
# Execute Disable Bit Support: Can help prevent certain classes of malicious "buffer overflow" attacks when combined with supporting operating system. This is an optional feature and is available on the latest Intel Pentium M Processors.
# Support for Intel Mobile Voltage Positioning (Intel MVP IV): Dynamically lowers voltage based on processor activity to lower thermal design power enabling smaller notebooks.
# Micro FCPGA & FCBGA packaging technology: Optimized for a range of thinner, lighter designs including <1" thick that deliver outstanding performance.
P4:
# Features & Benefits : Features of the Intel Pentium 4 processor 6xx supporting Hyper-Threading Technology:
# 2 MB of L2 Cache: A larger cache size can help the processor more efficiently run many popular applications in digital imaging, music, video and gaming.
# Intel Extended Memory 64 Technology: Provides flexibility for future applications that support both 32-bit and 64-bit computing.
# Execute Disable Bit: Can improve protection against malicious "buffer overflow" attacks when properly enabled with a supporting operating system.
# Enhanced Intel SpeedStep Technology: Enables cooler and quieter PC designs (depending on system implementation and usage).
