Notebook implementations

Carmel platform (2003)

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

Centrino Carmel platform
Mobile chipset an Intel Mobile 855 Express series chipset (codenamed Odem or Montara with Intel Extreme Graphics 2), including ICH4M southbridge.
Mobile processor Processors - Socket 479
Wireless network an Intel PRO/Wireless 2100B (codenamed Calexico) or later 2200BG mini-PCI Wi-Fi adapter (codenamed Calexico2).

Industry-watchers initially criticized the Carmel platform for its lack of an IEEE 802.11g-solution, 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 launch, and that it only wanted to launch products based on a finalized standard. 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.
Centrino Sonoma platform
Mobile chipset an Intel Mobile 915 Express series chipset (codenamed Alviso with Intel GMA 900), including ICH6M southbridge.
Mobile processor Processors - Socket 479
Wireless network an Intel PRO/Wireless 2200BG or 2915ABG mini-PCI Wi-Fi adapter (both codenamed Calexico2).

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.

Centrino Napa platform
Mobile chipset an Intel Mobile 945 Express series chipset (codenamed Calistoga with Intel GMA 950), including ICH7M southbridge.
Mobile processor Processors - Socket M / Micro-FCBGA
  • an Intel Core Solo, Core Duo (codenamed Yonah) processor, or
  • an Intel Core 2 Duo (codenamed Merom) processor with a 667 MT/s FSB for Napa Refresh platform, or
  • an Intel Core 2 Solo (codenamed Merom) processor with 533 MT/s FSB for Napa Refresh platform (Sept 2007).
Wireless network an Intel PRO/Wireless 3945ABG mini-PCIe Wi-Fi adapter (codenamed Golan).
  • Some newer models (as of 1st quarter 2007) of the Napa Refresh platform contain the newer 4965AGN (a/b/g/draft-n) 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 (Core Solo) 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 Thursday May 10, 2007.

Centrino Santa Rosa platform
Mobile chipset an Intel Mobile 965 Express series chipset (codenamed Crestline): 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 (IDA), better Windows Vista Aero support.[2]
  • RAM supported for PC2-4200 (DDR2-533) and PC2-5300 (DDR2-667) SO-DIMM.[3] Runs DDR2-800 SO-DIMMs at 667 MHz even though an 800 MT/s front side bus is supported.[4]
  • EFI-compliant firmware, a successor to BIOS.
  • optional NAND flash-memory caching branded as Intel Turbo Memory (codenamed Robson).
  • Ethernet LAN controller 82562V (codenamed Ekron-N) or Gigabit Ethernet LAN controllers 82566MM and 82566MC (codenamed Nineveh).
Mobile processor Processors - Socket P / Socket M / Micro-FCBGA
  • an Intel Core 2 Duo (codenamed Merom) second generation processor with 800 MT/s FSB, or
  • an Intel Core 2 Duo (codenamed Penryn) 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[5] for Santa Rosa Refresh platform.
Wireless network an Intel WiFi Link 4965AGN (a/b/g/draft-n) mini-PCIe Wi-Fi adapter (codenamed Kedron).
  • 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.[6]

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.[7] 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 (3.5G), (codenamed Windigo) co-developed with Nokia.[8][9] After announcing a working partnership, both later retracted the deal citing the lack of a clear business case for the technology. Support for WiMAX (802.16) was originally scheduled for inclusion in Santa Rosa but was later delayed until Montevina in 2008.[8]

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.[10]

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,[11] but was delayed until July 15, due to problems with integrated graphics and wireless certification.[12]

Centrino Montevina platform
Mobile chipset an Intel Mobile Express series 4 chipset (codenamed Cantiga; GL40, GS45, GM45, PM45) with Intel GMA X4500 graphics technology and ICH9M southbridge, 1066 MT/s (667 MT/s for GL40) FSB. The GM45/GS45 graphics core is clocked at 533 MHz and 400 MHz for GL40, which contains ten unified shaders, up from the eight provided by GMA X3100.
  • RAM support for PC2-5300 (DDR2-667), PC2-6400 (DDR2-800), PC3-6400 (DDR3-800), PC3-8500 (DDR3-1066) SO-DIMM. (GL40 does not support DDR3-1066)

Calpella Platform (2009)

The codename Calpella refers to the sixth-generation Centrino platform. Though originally scheduled to premiere in Q3 2009 with the second iteration of Nehalem processors,[14] Intel had stated that due to pressure from computer manufacturers, they would delay the release of the platform until at least October 2009 (Q4 2009) to allow OEM partners to clear excess inventory of existing chips. This was believed to be spurred by the lowered demand due to unfavorable economic conditions throughout 2009.[15]

Mobile Internet Device

Menlow platform (2008)

On March 2, 2008, Intel introduced the Intel Atom processor brand[26] for a new family of low-power processor platforms. The components have thin, small designs and work together to "enable the best mobile computing and Internet experience" on mobile and low-power devices.

Intel's second generation MID platform (codenamed Menlow) contains a 45 nm Intel Atom processor (codenamed Silverthorne) which can run up to 2.0 GHz and a System Controller Hub (codenamed Poulsbo) which includes Intel HD Audio (codenamed Azalia).

Centrino Menlow platform
Mobile chipset an Intel SCH (codenamed Poulsbo) with integrated GMA 500 graphics (PowerVR SGX 535 based)
Mobile processor a 45 nm Intel Atom CPU (codenamed Silverthorne)
Wireless network a wireless radio

This platform was initially branded as Centrino Atom but the logo was dropped in August 2008; the logo had caused confusion between laptop and MID with previous marketing of Centrino stating only Intel chipsets are being used. Hence MIDs will be branded as Atom to allow integration with other OEM chipsets for the low-end market.[27][28]

Intel Centrino Wireless

Intel Centrino Wireless is the brand for Intel Wi-Fi and WiMAX adapters. The product line includes:

  • Intel Centrino Wireless-N 1000
  • Intel Centrino Advanced-N 6200
  • Intel Centrino Ultimate-N 6300
  • Intel Centrino Advanced-N + WiMAX 6250

Centrino with Intel vPro technology

Laptops with Intel vPro technology have hardware features that allow a system administrator to remotely access wired and wireless laptops for maintenance and servicing if the operating system is unresponsive or crashed and, when a laptop is connected to AC power (not on battery power), allow a sys-admin to remotely access the laptop when the system is asleep or laptop power is off. It is targeted more for businesses than consumers.[29]

Security technologies

Laptops with vPro have the typical dual-core or quad-core processor and wireless features of the Centrino family.

  • The vPro technology built into the chipset adds management, security, and remote-deployment features for: monitoring laptops (protected event logs, access to BIOS settings, out-of-band alerting, protected data storage), maintaining and updating systems (access to protected system information, remote power up, console redirection), repairing systems (remote boot, console redirection, preboot access to BIOS settings, protected events logs), and securing systems (remote power up, hardware filters for network traffic, agent presence checks/triggers, out-of-band alerting).
  • The 45 nm Centrino 2 package is based on the Penryn microprocessor and Q47/Q45 chipset. It includes a better graphics engine (integrated) than Centrino, and three key additional features: Transport Layer Security (TLS) secured communications over an open local area network (LAN) for wired laptops outside the corporate firewall (not supported for wireless states), support for Microsoft Network Access Protection (NAP), and support for out-of-band management and security features in Sx (all sleep states) when the laptop is inside the corporate firewall.
