My knowledge of technical aspects of computers is very limited, therefore I apologize if my question sounds stupid:
I've heard this claim that Centrino processors are considerably less power-demanding than other types/brands of notebook processors. Can anyone tell me if this indeed true???
Uh, Intel Centrino isnt a Processor, its a "mobile technology", the processor is just your run-of-the-mill Pentium M. The new technology's biggest weakness may be its confusing naming scheme. The Centrino technology, formerly code-named Banias, includes a CPU, chip set, and wireless hardware. The chip is called the Pentium M, (not to be confused with its Pentium III-M and Pentium 4-M predecessors), the chip set is the 855, and the wireless hardware is named the Intel Pro/Wireless 2100 Network Connection. To call a notebook a Centrino, and to reap the benefits of Intel's marketing muscle behind that name, vendors must use all three parts. Notebooks using only the processor and chip set will carry the Pentium M label. How does Centrino help battery life? For starters, the 1.3-GHz, 1.4GHz, 1.5-GHz, and 1.6-GHz Pentium M chips draw an average of less than 1 watt of power. (Intel also offers 1.1-GHz and 900-MHz versions, which average one-half watt, for subnotebooks and tablet PCs.) The older Pentium 4-M processors gobble an average of 2 watts. Most mobile users don't want to sacrifice performance to get long battery life. That won't be an issue for Pentium M-based notebooks, thanks to a more efficient processor architecture built from the ground up to be a mobile part (Intel's previous mobile chips are reconfigured desktop parts).The new chip completes more instructions per clock cycle than today's P4 chips (which favor higher MHz instead), and the Pentium M has a 1MB Level 2 cache (twice that of the P4's 512KB L2 cache). As a result, the three 1.6-GHz test notebooks landed impressive PC
WorldBench 4 scores, outpacing notebooks with faster-running P4 and P4-M processors. (got most of this info from PCWorld).
