Which is better and why, centrino or celeron?

Answer 1

Based on your question, I assume that you are trying to purchase a laptop.
To answer your question, first you have to know that Centrino is not a processor, it's a brand name for Intel's wireless mobile computing technology. Celeron is just a processor. In order for a computer to be certified as a Centrino system, it needs to have the following characteristics:

1. Intel mobile processor (either Pentium M, Core Solo, Core Duo)
2. Intel Mobile Express chipset (either 945 or 915)
3. Intel Pro/Wireless LAN MiniPCI adapters.

The main advantage to Centrino is Intel's claim to have undergone rigorous interoperability testing that make them more likely to work with other Centrino Certified wireless devices.

Celeron is Intel's "value" processor brand which typically underperforms systems that have Pentium and Core processors.

To sum it up, Celeron is typically priced lower and has less features than Centrino certified devices, but Celeron is still a decent buy (just an opinion). Centrino devices, by specification, have built-in power management and wireless networking capabilities. That doesn't mean that Celeron doesn't have all of the same features, mainly the difference is that it MAY or may not have the features and they MAY or may not have been tested for interoperability.

Answer 2

Centrino is nothing more than the combination of an Intel processor, and Intel motherboard and an Intel wireless adapter. Celeron is the actual processor. I would go with a Pentium over a Celeron.

You'll only get un-informed opinions!!

Maybe even outright lies!!

The genuine facts are at the Intel website. They make them!
