Brand name(s)

Arrandale is the code name for a family of mobile Intel processors, sold as mobile Intel Core i3, i5 and i7 as well as Celeron and Pentium. [1] [2] It is closely related to the desktop Clarkdale processor; both use dual-core dies based on the Westmere 32 nm die shrink of the Nehalem microarchitecture, and have integrated Graphics as well as PCI Express and DMI links.

Intel American semiconductor company

Intel Corporation is an American multinational corporation and technology company headquartered in Santa Clara, California, in the Silicon Valley. It is the world's second largest and second highest valued semiconductor chip manufacturer based on revenue after being overtaken by Samsung, and is the inventor of the x86 series of microprocessors, the processors found in most personal computers (PCs). Intel ranked No. 46 in the 2018 Fortune 500 list of the largest United States corporations by total revenue.

Intel Core brand name that Intel uses for various mid-range to high-end consumer and business microprocessors

Intel Core is a line of mid- to high-end consumer, workstation, and enthusiast central processing units (CPU) marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors of the time, moving the Pentium to the entry level, and bumping the Celeron series of processors to the low end. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets.

Clarkdale is the code name for an Intel processor, initially sold as desktop Intel Core i5 and Core i3 and Pentium. It is closely related to the mobile Arrandale processor; both use dual-core dies based on the Westmere 32 nm die shrink of the Nehalem microarchitecture, and have integrated Graphics as well as PCI Express and DMI links.


Arrandale is the successor of the 45 nm Core-microarchitecture-based Penryn processor that is used in many of the mobile Intel Core 2, Celeron and Pentium Dual-Core processors. While Penryn typically used both a north bridge and a south bridge, Arrandale already contains the major northbridge components, which are the memory controller, PCI Express bus for external graphics, integrated graphics, and the DMI interface, making it possible to build more compact systems.

Penryn (microprocessor) Intel microprocessor

Penryn is the code name of a processor from Intel that is sold in varying configurations as Core 2 Solo, Core 2 Duo, Core 2 Quad, Pentium and Celeron.

Core 2 is a brand encompassing a range of Intel's consumer 64-bit x86-64 single-, dual-, and quad-core microprocessors based on the Core microarchitecture. The single- and dual-core models are single-die, whereas the quad-core models comprise two dies, each containing two cores, packaged in a multi-chip module. The introduction of Core 2 relegated the Pentium brand to the mid-range market, and reunified laptop and desktop CPU lines for marketing purposes under the same product name, which previously had been divided into the Pentium 4, Pentium D, and Pentium M brands.

Celeron is a brand name given by Intel to a number of different low-end IA-32 and x86-64 computer microprocessor models targeted at low-cost personal computers.

The Arrandale processor package contains two dies: the 32 nm processor die with the I/O connections, and the 45 nm Intel HD Graphics (Ironlake) controller and integrated memory controller die. [3] Physical separation of the processor die and memory controller die resulted in increased memory latency.

Arrandale was released on 7 January 2010, during CES 2010. [4]

Brand names

Arrandale processors were sold under the Celeron, Pentium, Intel Core i3, Intel Core i5 and Intel Core i7 brand names, with only the Core i7 models using the full L3 cache and all features. Processors ending in E instead of M are embedded versions with support for PCIe bifurcation and ECC memory, while the regular mobile versions only support a single PCIe port and non-ECC memory. The Celeron versions of Arrandale have the smallest L3 cache of just 2 MB. [5]

Pentium an Intel microprocessor

Pentium is a brand used for a series of x86 architecture-compatible microprocessors produced by Intel since 1993. In their form as of November 2011, Pentium processors are considered entry-level products that Intel rates as "two stars", meaning that they are above the low-end Atom and Celeron series, but below the faster Core i3, i5, i7, i9, and high-end Xeon series.

ECC memory auto-correcting computer data storage

Error-correcting code memory is a type of computer data storage that can detect and correct the most common kinds of internal data corruption. ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing.

Consumer Ultra-Low Voltage (CULV) is a computing platform developed by Intel. It has been estimated that this market could reach 10 million CULV laptops shipped within 2009. Competing platforms are the VIA Nano, AMD Yukon, AMD Nile notebook platform, and graphic chips from the Nvidia GeForce line within the "Nvidia Ion platform". Some of the lowest power using processors for the ultra thin CULV category may be only a few watts more than the Intel Atom, which is rated at no more than 2.5 W. Because of their low power and heat output, CULV enables very thin computer systems, and long battery life in notebook computers.

Xeon brand of x86 microprocessors from Intel

Xeon is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded system markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have some advanced features such as support for ECC memory, higher core counts, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability features responsible for handling hardware exceptions through the Machine Check Architecture. They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the Machine Check Exception. Some also support multi-socket systems with two, four, or eight sockets through use of the Quick Path Interconnect bus.

The NetBurst microarchitecture, called P68 inside Intel, was the successor to the P6 microarchitecture in the x86 family of CPUs made by Intel. The first CPU to use this architecture was the Willamette-core Pentium 4, released on November 20, 2000 and the first of the Pentium 4 CPUs; all subsequent Pentium 4 and Pentium D variants have also been based on NetBurst. In mid-2004, Intel released the Foster core, which was also based on NetBurst, thus switching the Xeon CPUs to the new architecture as well. Pentium 4-based Celeron CPUs also use the NetBurst architecture.

The P6 microarchitecture is the sixth-generation Intel x86 microarchitecture, implemented by the Pentium Pro microprocessor that was introduced in November 1995. It is frequently referred to as i686. It was succeeded by the NetBurst microarchitecture in 2000, but eventually revived in the Pentium M line of microprocessors. The successor to the Pentium M variant of the P6 microarchitecture is the Core microarchitecture which in turn is also derived from the P6 microarchitecture.

Nehalem (microarchitecture) microarchitecture

Nehalem is the codename for an Intel processor microarchitecture released in November 2008. Nehalem was used in the first generation of the Intel Core processors. Nehalem is the successor to the older Core microarchitecture.

Sandy Bridge Intel processor microarchitecture

Sandy Bridge is the codename for the microarchitecture used in the "second generation" of the Intel Core processors - the Sandy Bridge microarchitecture is the successor to Nehalem microarchitecture. Intel demonstrated a Sandy Bridge processor in 2009, and released first products based on the architecture in January 2011 under the Core brand. Developed primarily by the Israeli branch of Intel, the codename was originally "Gesher".

Pentium Dual-Core

The Pentium Dual-Core brand was used for mainstream x86-architecture microprocessors from Intel from 2006 to 2009 when it was renamed to Pentium. The processors are based on either the 32-bit Yonah or 64-bit Merom-2M, Allendale, and Wolfdale-3M core, targeted at mobile or desktop computers.

Wolfdale (microprocessor)

Wolfdale is the code name for a processor from Intel that is sold in varying configurations as Core 2 Duo, Celeron, Pentium and Xeon. In Intel's Tick-Tock cycle, the 2007/2008 "Tick" was Penryn microarchitecture, the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23. This replaced the Conroe processor with Wolfdale.

Clarksfield is the code name for an Intel processor, initially sold as mobile Intel Core i7. It is closely related to the desktop Lynnfield processor, both use quad-core dies based on the 45 nm Nehalem microarchitecture and have integrated PCI Express and DMI links.

Socket G1

Socket G1, also known as rPGA 988A, is Intel's CPU socket for their line of mobile Core i7, the successor to the Core 2 line. It is based on Intel's Nehalem architecture which was first available for the 1366-pin "Socket B", which, like its predecessor, LGA775, uses the LGA socket configuration. Later followed the updated LGA-1156 socket, which moved the QPI and PCI-express controller off the Northbridge and onto the CPU. As a result of the lower pin count, LGA-1156 systems, and later, socket G1 systems, can only run in Dual-channel memory mode, as opposed to the Triple-channel mode which is unique to the LGA-1366 platform. The Nehalem's mobile variant was released on September 23, 2009 in the form of the i7-720QM, 820QM, and 920XM models, followed by the i7-740QM, 840QM, and 940XM models on June 21, 2010. The newer CPUs use the new Clarksfield core, which maintained the same 45 nm manufacturing process as the desktop-based Nehalems. Nehalem received a die shrink on January 7, 2010, under the core name of Westmere. With the Intel GMA HD Graphics Ironlake core packaged onto the CPU substrate, but not integrated directly to the processor die, it goes on to create the Arrandale-based line. The current CPUs to use this package are the Core i7-6x0M series, the Core i5-4x0M series, the Core i5-5x0M series, the Core i3-3x0M series, and finally the Pentium P6x00 series and Celeron P4x00 series which were released on March 28, 2010. However, not all of these are available for Socket G1, as some of them are only available in a BGA package. They are also known as PGA988 socket processors.

Westmere (microarchitecture) Intel processor family

Westmere is the code name given to the 32 nm die shrink of Nehalem. While sharing the same CPU sockets, Westmere included Intel HD, UHD and Iris Graphics, Nehalem did not.
