Mobile Celeron and Celeron M

Mobile Celeron and Celeron M

Mobile Celeron in BGA2 package

The same Mendochino (Celeron-A) 0.25μ, 32 KB L1-Cache and 128 KB L2-Cache but uses lower power voltage 1.5-1.9V and two power-saving modes - Quick Start and Deep Sleep. Shipped in the small, 615-pin BGA2 or Micro-PGA2 package.

Tualatin-256

These were the first Mobile Celerons, based on the Tualatin core. These differed from their desktop counterparts in that the Mobile series were offered in both 100 MHz and 133 MHz FSB. Like the desktop Tualatins, these chips had 256KB of L2 cache.

Northwood-256

These are the Mobile Celeron range used in laptops. Also based on the Northwood core, they feature a 256 KiB L2 Cache. These Celeron processors were a good deal higher performing than the desktop counterparts because of their larger L2 cache sizes. They were eventually replaced by the Celeron M brand which is built around the Pentium M processor design.

Banias-512

This Celeron (sold under the Celeron M brand) is based on the Banias Pentium M, and differs from its parent in that it has half the L2 cache, and does not support the clock-varying SpeedStep technology. It performs reasonably well compared to the Pentium M, but battery life is noticeably shorter on a Celeron M–based notebook than it is on a comparable Pentium M notebook.

A system based on the Celeron M processor may not use the Centrino brand name, regardless of what chipset and Wi-Fi components are used.

In Intel's "Family/Model/Stepping" scheme, Banias Celeron Ms and Pentium Ms are family 6, model 9 and their Intel product code is 80535.

Shelton

The Shelton core is a Banias core without any L2 cache and SpeedStep. It is used in Intel's small form factor D845GVSH motherboard, intended for Asian and South American markets. The processor identifies itself as a "Intel Celeron 1.0B GHz", to differentiate it from the previous Coppermine-128 and "Tualeron" 1.0 GHz processors.

The "Shelton'08" is a basic platform for a low cost notebook released by Intel at January 2008. The platform uses Intel's single-core Diamondville CPU with a clock frequency of 1.6 GHz and a 533 MHz FSB and power consumption of 3.5W. Its total power consumption is around 8W, translating to battery usage time of between 3-4 hours. The platform consists of a 945GSE chipset, which includes built-in DirectX 9 graphics and supports single channel DDR2 memory. A 802.11g Wi-Fi module, USB/PATA port SSD (solid state drive), and a 7- or 8-inch panel will typically round out the platform.

Dothan-1024

A 90 nm Celeron M with half of the L2 cache of the 90 nm Dothan Pentium Ms (twice the L2 cache of the 130nm Celeron Ms, though), and, like its predecessor, lacking SpeedStep. The first Celeron Ms that supports the XD bit was released in January 2005, in general any Celeron M released after that supports the XD bit. There is also a 512 kib low voltage version which is used in the Asus EEE PC.

In Intel's "Family/Model/Stepping" scheme, Dothan Celeron Ms and Pentium Ms are family 6, model 13 and their Intel product code is 80536.

Yonah-1024

The Celeron M 400-series is a 65 nm Celeron M based on the single-core Yonah Core Solo CPU. Like its predecessors in the Celeron M series, this Celeron M has half of the L2 cache (1 MiB) of Core Solo and lacks SpeedStep. This core also brings new features to Celeron M including a higher front side bus (533 MT/s), SSE3 instructions. September 2006 and January 4, 2008 mark a discontinuation of many Celeron M branded CPUs.

Merom-1024

The Celeron M 520 (1.6 GHz), 530 (1.73 GHz), 540 (1.86 GHz), 550 (2.0 GHz), and 560 (2.13 GHz) are single-core 65 nm CPUs based on the Merom Core 2 architecture. They feature a 533 MHz FSB, 1 MiB of L2 cache (half that of the low end Core 2 Duo's 2 MiB cache), XD-bit support, and Intel 64 technology, but lack SpeedStep and Virtualization Technology. January 4, 2008 marked the discontinuation of Merom-1024 CPUs.
