In 2010, the meaning of the brand name changed to wireless computer networking. The combination of chipset denotes the old platform of Centrino.

When compared to non-Centrino systems, the system with Centrino works better and has longer battery life. The Intel Centrino is the new brand name used by Intel for its wireless functions.

What is Pentium?

By architecture, Pentium has the best and highest performance when compared to others. Hyperthreading is a unique feature of Pentium.

But the i-series may disable unique features of Pentium sometimes. The word Pentium is derived from the Greek term pente. The term pente means five. The ium ending is taken from Latin.

It denotes the 80×86 processors. The Pentium was split into two by Intel in 2017. They are Pentium silver and Pentium Gold.

The Pentium Silver target low-power devices, whereas Pentium gold target entry-level laptops. Kaby Lake is an example of Pentium gold.

The Pentium is used in laptops, desktops, and servers. They used in their skins. 586 or i586 are the name of the original Pentium branded. The Pentium processors are a huge success for Intel and make sure to continue to future generations.

Intel changed the name of the Pentium from dual-core to Wolfdale-3M in 2009. Since it became disappear in 2006 and give a come back in 2007.

The logos of Pentium underwent various changes since 2005. The current Pentium has two different logos for gold and silver split-ups.

What is Centrino?

In 2003, Intel released the first generation Centrino in the name of Carmel. It is considered the code name of Centrino. It undergoes various criticisms for its lack of ability to connect to IEEE 802.11g.

In 2005, Intel released the second generation Centrino in the name of Sonoma. It is the code name of second-generation Centrino. The battery life of Sonoma has proven its excellence.

In2006, Intel released its third generation Centrino in the name of Napa Platform. It is the code of third-generation Centrino.

The fourth-generation Centrino is called the Santa Rosa platform which is released in 2007. The fifth-generation Centrino is called the Monetiva platform which is released in 2008.

The sixth-generation Centrino is called the Calpella platform which is released in 2009. The seventh-generation Centrino is called the Huron River platform which is released in 2011.

The eighth-generation Centrino is called the Cheif River platform which is released in 2012. The ninth-generation Centrino is called the Shark Bay platform which is released in 2013.

The Centrino is not just a processor but a platform with a combination of processors, chips, etc. It is simply called marketing type.

It is used to promote laptops with wireless functions. It overcomes many lacks and becomes a stable processor with many versions. It provides long-lasting battery life and high compatibility within the systems.
