Difference between Centrino (Pentium M) and Pentium IV
August 11th, 2005 by gaurav | 9 Comments | Filed in ,I have been planning to replace my old desktop PC with a new one and now I have to decide whether to go for a desktop or notebook (laptop) computer. My first preference is laptop keeping in view the kind of mobility it offers but there are other factors that I have to take of such as speed and price. Notebooks are available starting from Rs.30,000 onwards but they don’t have best processor serving it.
In recent past Intel has come up with new processors especially for notebook users so it has become diffcult to decide what to go for. I have started looking on net for information which is essential for notebook buyers to know about latest processors. This is what I have found -
- Basically there are 2 kind of processors from Intel : Penitum 4 & Pentium M (which is a mobile processor).
- Pentium M processor + Intel 855 chipset+ Intel/Pro wireless network connection makes a Centrino. Remember CENTRINO is not just a processor but a combination of all three.
- The Pentium M was built from the ground up, it is a completely new design from Intel
- Centrino uses far less power than any previous Intel processor consumes, thats why its battery life is good on notebooks which uses Centrino.
- Centrino is available in 1.3, 1.4, 1.5, 1.6 and 1.7GHz speeds. It has 1Mb of on-die L2 cache.
- Frequency doesn’t matter so much, as long as the chip design includes big caches and highly accurate branch prediction. The Centrino processor has met or exceeded expectations here, making notebooks based on the Mobile Pentium 4 completely unappealing for almost all practical purposes. In tests, Centrino—which is actually based on a modified Pentium III core and Pentium 4-like bus—outperformed the higher-frequency, power-hogging Pentium 4 devices hands down.
After having gone through all this I think Centrino is good option. If anyone of you is using Centrino or any other notebooks yours views on it will be helpful for me in deciding what to buy.
