| Intel®
Core™ Second Generation Microarchitecture (Sandy Bridge/Ivy Bridge) |
Intel®
Core™ Second Generation
Microarchitecture (code-named "Sandy Bridge") is the
latest iteration of the Intel Core microarchitecture. The first
microprocessor models start at 32nm
with
a new socket (LGA 1155). High-end desktop versions, "Sandy
Bridge-E", with a higher
contact count socket (LGA 2011) are now available. In April 2012, 22nm models code-named "Ivy Bridge" will be released. "Ivy Bridge" promises to be another major boost in performance and efficiency. "Ivy Bridge" will, among other improvements, feature Intel TriGate Transistor technology for superior management of current leakage and thermal characteristics. With features such as Turbo Boost (v2.0) that self-overclocks all cores on demand, "Sandy Bridge" and "Ivy Bridge" customers can expect strong performance from mainstream PCs. All "Sandy Bridge" processors except for the high-end "Sandy Bridge-E" include on-chip graphics. Models include Core i7-E3nnn, Core i7-2nnn, Core i5-2nnn, Core i3-2nnn, Pentium Gnnn and Celeron-branded dual-core and single-core desktop versions. |

| Intel® Microarchitecture code-named Nehalem/Westmere | Intel®
Microarchitecture code-named "Nehalem/Westmere",
an extension of the original
Intel® Core™/Penryn Microarchitecture,
is the 2009/2010 processor family from Intel Corporation.
The original
"Nehalem" processors are based upon a 45nm
manufacturing process. The second
release, a 32nm
shrink broadly nicknamed "Westmere", came to market in 2010.
Most processors from this architecture will be discontinued mid
2012. Nehalem/Westmere desktop processor series include Intel® Core™i7 Extreme, Core i7, Core i5, Core i3, a very limited offering of Pentium™ G and OEM Celeron™ G models. All are multi-core processors. |
||||||||||||||||||||||||||||||||||||||||||||||
| Intel® Core™/Penryn | The Intel® Core™/Penryn Microarchitecture, originally released in 2007, includes Intel Core 2 Extreme, Core 2 Quad, Core 2 Duo, Pentium® Dual Core, Celeron® Dual Core and derivative single core Intel Celeron processors. Most PCs and processors based upon this technology have been discontinued. | ||||||||||||||||||||||||||||||||||||||||||||||
| Intel® Atom™ | The
Intel® Atom™ Microarchitecture is a radical departure from
the past years of Intel products. Introduced in the summer of
2008, original Atom processors were based upon 45nm technology
with idle power consumption
measured in milliwatts. The latest models are made using 32nm
technology.
Thermal Design Power (TDP) is a fraction of what most
desktop processors dissipate. The lowest power and lowest performing Atom processors can operate without heatsinks, saving much weight and space in electronic products such as GPS systems, telephones, tablets and Ultra-Low-Cost PCs (ULCPCs). Intel Atom is only offered in mini-ITX format. |

| About Product Discontinuance: |
Processors may remain in retail channels for weeks, months, or years. Some final steppings (versions) are relegated to OEM/tray production and may be found on the market with eMachines and other second and third tier brands long after discontinued by Acer, Dell and HP. A minority are transferred to the Intel Embedded Technology Division where they can be ordered for special markets for years to come. Product discontinuance references in this document are based upon published current production first and second tier vendor model offerings and/or upon factory distributor order cutoff for retail (non-OEM) processors. Final production and shipping schedules are not generally considered because those schedules are often months after Acer, Dell, and Hewlett-Packard have revised their product lines with newer products. |

Legend LGAnnnn = Land Grid Array, a layout for CPU contacts where a large number of matching small ball and sockets serve for electrical connections between the processor and main system board. The number indicates the contact count for the CPU to socket interface. QPI = QuickPath Interconnect: This technology from Intel is similar to AMD HyperTransport. It replaces the Front Side Bus for data transfers to and from system memory. FSB = Front Side Bus: the speed in millions of cycles per second that data is transferred to and from main system memory. The FSB spec is nearing obsolescence as it is applicable only to LGA775 processors. LGA775 will be retired in early 2012. OEM = Original Equipment Manufacturer: a systems builder such as Dell. Most Intel OEM CPUs are not offered for individual retail purchase. Product information including production and discontinuance may not be available to the public. L2 Cache RAM = On-chip ultra-high speed memory where frequent instructions and data are cached for very quick access. Generally, the more L2 Cache, the faster the processor. Most L2 Cache is now assigned to individual cores. Except for the Celeron 400 series and Atom, L2 Cache is not listed in this table. L3 Cache RAM = On-chip ultra-high speed memory for very quick access. L3 Cache is often shared among cores. Generally, the more L3 Cache, the faster the processor. All cache in this table is L3 except for the Celeron 400 series and certain Atom processors. GHz as nn.nn/nn.nn = CPU core speed in gigahertz showing base and turbo speeds. Turbo speed allows individual CPU cores to briefly operated above base speed depending upon total load. |

About Product Discontinuance: |
|
Processors may remain in retail channels for weeks, months, or years. Some final steppings (versions) are relegated to OEM/tray production and may be found on the market with eMachines and other second and third tier brands long after discontinued by Acer, Dell and HP. A minority are transferred to the Intel Embedded Technology Division where they can be ordered for special markets for years to come. Product discontinuance references in this document are based upon published current production first and second tier vendor model offerings and/or upon factory distributor order cutoff for retail (non-OEM) processors. Final production and shipping schedules are not generally considered because those schedules are often months after Acer, Dell, and Hewlett-Packard discontinue sales. One exception is eMachines, a subsidiary of Acer. eMachines sells computers based upon older processors long after others have moved to newer technology.
|
Upcoming Processors and Technologies: |
|
In 2012, Intel will shrink "Sandy Bridge" to 22 nanometers to create "Ivy Bridge". These new processors will be made using Intel TriGate Transistor technology for lower power consumption and better thermal performance. TriGate is the basis for all future Intel CPUs. Following "Ivy Bridge", Intel will introduce "Haswell" at 22 nanometers. Reportedly a revolutionary processor redesign, "Haswell" is expected to market in 2013. In 2014, "Broadwell" will debut at 14 nanometers. In 2015, "Skylake" is expected at 14nm. In 2016, "Skymont" is expected at 10nm. | |||||
