Centrino


Centrino was a brand name of Intel Corporation which represented its Wi-Fi and WiMAX wireless computer networking adapters. The brand name was first used by the company as a platform-marketing initiative. The change of the meaning of the brand name occurred on January 7, 2010. The Centrino name for laptops was replaced by the Ultrabook.
The old platform-marketing brand name covered a particular combination of mainboard chipset, mobile CPU and wireless network interface in the design of a laptop. Intel claimed that systems equipped with these technologies delivered better performance, longer battery life and broader wireless network interoperability than non-Centrino systems.
The product line name for Intel wireless products became Intel Centrino Wireless in 2010. The Centrino brand was ultimately discontinued in 2013.

Carmel platform (2003)

Intel used "Carmel" as the codename for the first-generation Centrino platform, introduced in March 2003.

  • an Intel Pentium M processor with a 400 MT/s FSB, or
  • an Intel Pentium M processor with a 400 MT/s FSB.
    • Wireless networkan Intel PRO/Wireless 2100B or later 2200BG mini-PCI Wi-Fi adapter.
    Industry-watchers initially criticized the Carmel platform for its lack of support for IEEE 802.11g, because many independent Wi-Fi chip-makers like Broadcom and Atheros had already started shipping 802.11g products. Intel responded that the IEEE had not finalized the 802.11g standard at the time of Carmel's announcement.
    In early 2004, after the finalization of the 802.11g standard, Intel permitted an Intel PRO/Wireless 2200BG to substitute for the 2100. At the same time, they permitted the new Dothan Pentium M to substitute for the Banias Pentium M. Initially, Intel permitted only the 855GM chipset, which did not support external graphics. Later, Intel allowed the 855GME and 855PM chips, which did support external graphics, in Centrino laptops.
    Despite criticisms, the Carmel platform won quick acceptance among OEMs and consumers. Carmel could attain or exceed the performance of older Pentium 4-M platforms, while allowing for laptops to operate for 4 to 5 hours on a 48 W-h battery. Carmel also allowed laptop manufacturers to create thinner and lighter laptops because its components did not dissipate much heat, and thus did not require large cooling systems.

    Sonoma platform (2005)

    Intel used Sonoma as the codename for the second-generation Centrino platform, introduced in January 2005.
    CentrinoSonoma platform
    Mobile chipsetan Intel Mobile 915 Express series chipset, including ICH6M southbridge.
    • RAM supported for PC2-4200 SO-DIMM.
    Mobile processorProcessors - Socket 479
  • an Intel Pentium M processor.
    • Wireless networkan Intel PRO/Wireless 2200BG or 2915ABG mini-PCI Wi-Fi adapter.
    The Mobile 915 Express chipset, like its desktop version, supports many new features such as DDR2, PCI Express, Intel High Definition Audio, and SATA. Unfortunately, the introduction of PCI Express and faster Pentium M processors causes laptops built around the Sonoma platform to have a shorter battery-life than their Carmel counterparts; Sonoma laptops typically achieve between 3.5–4.6 hours of battery-life on a 53 W-h battery.

    Napa platform (2006)

    The codename Napa designates the third-generation Centrino platform, introduced in January 2006 at the Winter Consumer Electronics Show. The platform initially supported Intel Core Duo processors but the newer Core 2 Duo processors were launched and supported in this platform from July 27, 2006 onwards.
    CentrinoNapa platform
    Mobile chipsetan Intel Mobile 945 Express series chipset, including ICH7M southbridge.
    • RAM supported for PC2-4200 and PC2-5300 SO-DIMM.
    Mobile processorProcessors - Socket M / Micro-FCBGA
  • an Intel Core Solo, Core Duo processor, or
  • an Intel Core 2 Duo processor with a 667 MT/s FSB for Napa Refresh platform, or
  • an Intel Core 2 Solo processor with 533 MT/s FSB for Napa Refresh platform.
    • Wireless networkan Intel PRO/Wireless 3945ABG mini-PCIe Wi-Fi adapter.
  • Some newer models of the Napa Refresh platform contain the newer 4965AGN wireless cards.
    • Intel uses Centrino Duo branding for laptops with dual-core Core Duo processors and retains the Centrino name for laptops with single core processors. Some of the initial Core Duo laptops are still labeled as Intel Centrino rather than Centrino Duo.

    Santa Rosa platform (2007)

    The codename Santa Rosa refers to the fourth-generation Centrino platform, which was released on May 10, 2007.
    CentrinoSanta Rosa platform
    Mobile chipsetan Intel Mobile 965 Express series chipset : GM965 with Intel GMA X3100 graphics technology or PM965 with discrete graphics, and ICH8M southbridge, 800 MT/s front side bus with Dynamic Front Side Bus Switching to save power during low utilization.
    • Intel Dynamic Acceleration, better Windows Vista Aero support.
    • RAM supported for PC2-4200 and PC2-5300 SO-DIMM. Runs DDR2-800 SO-DIMMs at 667 MHz even though an 800 MT/s front side bus is supported.

  • an Intel Core 2 Duo second generation processor with 800 MT/s FSB, or
  • an Intel Core 2 Duo 45 nm processor with 800 MT/s FSB and SSE4.1, which will add 47 new instructions to SSSE3. It was scheduled for release in January 2008 for Santa Rosa Refresh platform.
    • Wireless networkan Intel WiFi Link 4965AGN mini-PCIe Wi-Fi adapter.
  • Wireless-N technology boasts a 5X speed increase, along with a 2X greater coverage area, and supports 2.4 GHz and 5 GHz signal bands, with enough bandwidth for high definition audio and video streams.
    • The Santa Rosa platform comes with dynamic acceleration technology, allowing single threaded applications to execute faster. When a single threaded application is running, the CPU can turn off one of its cores and overclock the active core. In this way the CPU maintains the same Thermal Profile as it would when both cores are active. Santa Rosa performs well as a mobile gaming platform due to its ability to switch between single threaded and multithreaded tasks. Other power savings come from an Enhanced Sleep state where both the CPU cores and the chipset will power down.
    The wireless chipset update was originally intended to include WWAN Internet access via HSDPA, co-developed with Nokia. After announcing a working partnership, both later retracted the deal citing the lack of a clear business case for the technology. Support for WiMAX was originally scheduled for inclusion in Santa Rosa but was later delayed until Montevina in 2008.
    It is branded as "Centrino Pro" when combined with the enhanced security technologies Intel introduced with vPro and "Centrino Duo" when they are not used.

    Montevina platform (2008)

    The codename Montevina refers to the fifth-generation Centrino platform, now formally named Centrino 2 to avoid confusion with previous Centrino platforms. It was scheduled for release at Computex Taipei 2008, which took place on June 3–7, 2008, but was delayed until July 15, due to problems with integrated graphics and wireless certification.

It was planned to consume no more than 29W, compared to Merom's and first-generation Penryn's 34W TDP. But after release only a few models have 25W TDP and the rest still have 35W TDP, besides the Q series TDP is 45W.
