This page of this website covers the many different types of processor socket used by Intel and AMD processors on motherboards made specifically for one or more ranges of their processors. AMD and Intel motherboard sockets are never interchangeable; they can only be used by the products of the only manufacturer that they have been designed to support.
The rate at which Intel and AMD change the kind of motherboard sockets that their desktop PC processors use is confusing as well as being infuriating, because it means that even if the motherboard form-factor remains the same (ATX or micro-ATX), every time the type of processor housing changes or there are technical changes to the existing platforms, if Intel is your choice of manufacturer, a new motherboard usually has to be purchased if you want to upgrade from one type of socket to another, or even use a more advanced processor that uses the same type of socket. You have no choice in the matter because the previous processor housing is then no longer supported. AMD provides far better backward-compatibility of its latest processors with its previous socket type, but, even with AMD, when a radically new CPU architecture comes into being a new motherboard will be required.
PROCESSOR PROBLEMS AND SOLUTIONS
Click here! to visit the page on this site devoted to processor problems and their solutions.
The image above shows a zero-insertion-force (ZIF) processor socket. The pin holes match the pin layout of the processor and so, when aligned correctly, the processors that the socket supports should just drop into the socket without using any force. The processor is dropped into the socket with the brown arm at the bottom of the socket raised. When the processor is inserted, the arm is lowered all the way down, thereby fixing the processor into the socket. AMD has always used pins on its processors. Intel used to use pins but then changed to using metal contact points on the processor that match metal pits in the socket. The heatsink and fan cooling unit is fixed to the plastic protrusions in the middle of the left and right sides of the socket shown in the image above.
AMD usually makes its desktop PC processor sockets last much longer than Intel. For example, the processors that run from its Socket AM3 socket are backwards-compatible with its predecessor, Socket AM2+ - usually only if a BIOS update for the motherboard is installed. This means that a Socket AM3 processor (e.g., a Athlon II and Phenom II) will work in a Socket AM2+ motherboard. However, a Socket AM2+ processor cannot run on a Socket AM3 motherboard. In this case, there is no forward compatibility. This means that owners of a Socket AM2+ motherboard can upgrade the processor without having to change the motherboard or RAM memory, but if a user wants an AM3 motherboard, an AMD Socket AM3 processor has to be purchased.
Socket AM2+ was the successor to Socket AM2 that was used by several AMD processors such as Athlon 64 X2. Socket AM2+ is fully compatible with Socket AM2, so that processors designed for Socket AM2 run on Socket AM2+ motherboards and vice versa. The circumstances differ from socket to socket for both AMD and Intel sockets, so you have to research what backward and forward compatibility applies to a particular socket.
Note well that if you buy a processor and a motherboard that can only run that processor if a BIOS update is installed, you have to have an earlier processor that the motherboard supports in order to be able to install the BIOS update. So, if you buy a processor and a motherboard and don't have an earlier supported processor, make sure that the motherboard supports that processor outright (without requiring a BIOS update.) Support information is made available on the motherboard manufacturer's website.
With Intel, a change of processor socket (say Socket LGA775 to Socket LGA1366 or Socket LGA1366 to Socket LGA2011 ) almost always means the user of the initial socket type having to change the motherboard, processor and sometimes even the RAM memory if a new type of memory is made available at the same time as the new processor.
In short, when Intel brings out a new range of processors, it almost always has a new socket type that is not backwards-compatible with its predecessor socket type or forwards-compatible with the next socket type. Moreover, later Intel processors made for a particular socket type may also require a new motherboard, because technical improvements to it make it impossible to run the latest processors of a particular socket type on earlier motherboards that use that socket type. You have to research what applies with a particular Intel socket type and the particular model of processor and motherboard combination that is required to make them work together.
This usually makes upgrading an Intel-based desktop PC much more expensive than upgrading an AMD-based PC, especially given that AMD processors are usually cheaper than equivalent Intel processors and Intel-based motherboards are usually more expensive than AMD-based motherboards.
The current sockets used by AMD for its desktop processors are now Socket AM3 and Socket AM3+ and the new Socket FM1 for AMD's recently-released Series-A Fusion APU range of desktop processors, code-named Lynx, that have and inbuilt graphics chip. (The laptop APUs have the same name but have the code-name, Llano.)
AMD released a few versions of its improved second-generation A-Series APU processors, code-named Trinity, for laptops in May 2012. The versions for the desktop PC, code-named Piledriver, are expected to be released later in 2012. By June 2012, the new processors were being shipped to PC manufacturers, but were only expected to be available as PCs several months later. A new socket type Socket FM2 is used. (Socket FM1 is used for the first-generation desktop APUs, code-named Lynx.) By June 2012, no information was available about backwards or forwards compatibility of the new socket with the previous generation of chips, which would answer the questions: Can the first generation FM1 chips run from the new socket (unlikely) and can the new FM2 chips run from Socket FM1 (quite possibly)?
Intel's current sockets are Socket LGA1156, LGA1155 and LGA2011, which replaced Socket LGA775. Socket LGA2011 has replaced Socket LGA1366, both of which run the Core i7 and Xeon processors, with LGA2011 running the latest versions. Socket LGA1156 runs Intel's first-generation Core i3, i5, i7 and Celeron and Pentium processors. It has been replaced by Socket LGA1155, which runs Intel's second-generation (Sandy Bridge) Core i3, i5, i7 processors and also runs the third-generation quad-core Core i5 and i7 Ivy Bridge processors, which were made available at the end of April 2012. None of these sockets is backwards- or forwards-compatible with any of the others - a new motherboard is required to run the processors that they support. Fortunately, the motherboards all still use DDR3 memory. (DDR4 memory had not been made available by May 2012).
The third generation of chips for the desktop PC - Core i5 and Core i7 - will run on motherboards using most of the previous generation Sandy Bridge chipsets, but some will require the replacement of the chipset by the motherboard manufacturer; a mere BIOS update does not suffice. Intel recommends that confirmation that a particular Socket LGA1155 motherboard is capable of running the new processors - or that the purchaser buys a motherboard with a 7-Series chipset. It may also be possible to run an Ivy Bridge processor on a motherboard designed for a Sandy Bridge processor, but that option depends on the motherboard manufacturer.
In October, 2011, AMD released the first 8-core (octo-core) processors for the desktop PC, called FX, which have the first entirely new architecture (called Bulldozer) that AMD has introduced since 2007.
Officially, a new Socket AM3+ motherboard with an AMD 990FX chipset is required for the Bulldozer processors, which provide an unlocked clock multiplier, allowing for unrestricted overclocking (running processors and other components, such as the memory and graphics card, at higher speeds than their stock speed). However, some Socket AM3 motherboards will run FX processors with a BIOS update. Socket AM3, first made available in February 2009, was the previous socket for AMD's processors, which don't provide onboard graphics.
Questions of Compatibility: AMD, AM3, and Bulldozer -
Since the FX processors have an entirely new architecture, in most cases, a motherboard with an entirely new socket, Socket AM3+, is officially required to run them. Therefore, in this case, AMD's renowned backward compatibility, which would have made it possible to run an FX processor on a Socket AM3 motherboard, has fallen down for the first time in many years. AMD initially made two 8-core models (FX8120 and FX8150) and one hexa-core (6-core) model (FX6100) available (the FX6200 model was added later). The quad-core FX-4100 model was made available later in 2011, so now the range consists of 4-, 6- and 8-core processors. The first letter of the model name is the number of cores it has. Here is a good review of the FX8150 (8-core) model:
On 5 January, 2011, Intel released its new second-generation Core i3, Core i5 and Core i7 quad-core processors that use the new Socket LGA1155 and new motherboard chipsets. Computers using the new processors will be rolling out during 2011 and 2012.
Guide to Intel Desktop Boxed Processors and Sockets [LGA775 to LGA1155] -
January 5, 2011. - Intel has officially released its second-generation Core i3, Core i5, and Core i7 processors, code-named Sandy Bridge. Intel is initially launching 20 processors, 6 Series chipsets and Centrino Wi-Fi and WiMax wireless adapters. The processors are quad-core (each processor houses four processor cores) and all of them have a graphics processor integrated on the same die (built with a 32-nanometer manufacturing process), making it unnecessary to have a separate graphics card. Intel intends to release dual-core models in February. Of course, dedicated PC gamers and professional video editors will still have to use one or more dedicated high-end graphics cards, which means that they will have to disable the integrated graphics chips.
The new Core processors provide a number of video-related technologies, such as Intel Insider, Quick Sync Video, and a new version of Wireless Display. The new processors are reported to be hugely improved compared to the first-generation Core i3, i5, and i7 models, by architectural changes and a new processor socket - Socket LGA1155 - and chipsets - P67 and H67 - to support them, which means having to buy a new motherboard for the processors if you are upgrading from the previous models. You will be able to reuse your DDR3 RAM memory. There are now three different processor sockets for the Core i7 processors: LGA1366, LGA1156 and the new LGA1155.
Intel Core i7-2600K review -
Intel's Second-Gen Core CPUs: The Sandy Bridge Review - "Although the processing cores in Intel's Sandy Bridge architecture are decidedly similar to Nehalem, the integration of on-die graphics and a ring bus improves performance for mainstream users. Intel's Quick Sync is this design's secret weapon, though." -
Efficiency Comparison: Sandy Bridge Vs. Intel And AMD CPUs - "The second-generation Core processors arrived with a bang, but what sort of progress can you expect in the performance per watt department? We compare Core i5/i7-2x00 to AMD's Phenom with four and six cores, as well as previous-gen parts from Intel." -
ASRock P67 Transformer: P67 Gets LGA 1156 Compatibility - "Upgrading to Intel's P67 [motherboard chipset for second-generation Core i3, i5, i7 processors] will certainly require a new motherboard, but the fact that you won't need a new CPU appears to be Intel's dirty-little-secret. ASRock found the secret and exploited it, bringing next-generation performance to today's processors." - http://www.tomshardware.co.uk/...
Back in 1997, Intel moved from housing its processors in Socket 7 (used in 66MHz FSB motherboards) and Super Socket 7 (SS7) sockets (used in 100MHz FSB motherboards) to using a slot (like a PCI/AGP/PCI Express slot), which it called Slot 1.
The Pentium 233MHz MMX processor was Intel's last SS7 processor.
It then proceeded with Slot 1 motherboards to run its Pentium II and Pentium III processors, and the cut-down economy versions (with none or less Level 2 cache), called the Celeron. These were the first processor to be installed in a slot on the motherboard instead of a socket.
All of a sudden, the cut-down Slot 1 Celeron processors couldn't compete with the SS7 AMD K6-2 and K6-3 processors and Intel turned the Celeron range back into socketed processors, this time using what it called Socket 370. The processor has 370 pins and the socket has the matching pin grid array to accept them.
The first Athlon processors made by AMD were slotted in AMD's Slot A instead of being socketed. A Slot A Athlon processor was the first to break the 1GHz barrier.
Then Intel dropped slot processors altogether in favour of socketed processors and AMD soon followed suite for its Athlon XP and Duron Socket A processors.
Some of the Celeron and the last Pentium 3 processors use motherboards that have the Flip Chip - Pin Grid Array or FC - PGA socket. - This is not a new socket, just a new name for Socket 370.
Socket 370 is long gone. The later Celeron and Celeron D (not a dual-core) processors do not use Socket 370 or Socket 478 motherboards, they use the same LGA775 socket as Pentium D (dual-core) and Pentium 4 processors, both of which have been superseded.
Intel Pentium 4 processors (superseded) use the earlier Socket 423 and Socket 478 or the Socket LGA775 motherboards, which also run the Intel Core 2 Duo (superseded dual-core processors) and Intel Core Quad (superseded quad-core processors).
The image below shows a Socket 478 motherboard that is no longer in production. The processor's socket is surrounded by the fitting to which the heatsink and fan unit is fitted. It is an unusual board because it only has one PCI slot (white, bottom left-hand corner).
AMD used Socket 7 motherboards (with a 66MHz FSB) for its K6 processors , and Super Socket 7 (SS7) motherboards (with a 100MHz FSB) for all of its K6-2, and K6-3 processors, but followed Intel when it decided to use a slot, which it called Slot A, for its first Athlon processors.
Click here! to go directly to a table containing the specifications of AMD's superseded K6, K6-2, and K6-3 processors.
Having also moved away from slotted processors, AMD Athlon, Athlon XP, and Duron processors went on to use Socket A (aka Socket 462) motherboards that are now no longer in production, but can still be bought from outlets such as eBay.
Socket 754 and Socket 939 motherboards run AMD's Athlon 64 and Sempron desktop processors, both of which have been discontinued. AMD then migrated all of its desktop processors to the Socket AM2 and Socket AM2+ platforms, which, as mention earlier are backward- and forward-compatible with each other.
AMD's Socket AM3 triple-core and quad-core Phenom II processors and the motherboards that run them were made available in February 2009. AMD's latest range of processors for the desktop PC was released in October 2011 is called FX and uses the new Socket AM3+.
Socket AM2 - http://en.wikipedia.org/wiki/Socket_AM2
Socket AM2+ - http://en.wikipedia.org/wiki/Socket_AM2%2B
Socket AM3 - http://en.wikipedia.org/wiki/Socket_AM3
Socket AM3+ - for the new range of AMD FX 8-core, hexa-core (6-core) and quad-core processors, released in October 2011, using the first completely new architecture employed by AMD since 2007, called Bulldozer. More information will be supplied as soon as it becomes available.
Socket LGA775 motherboards run Intel's Celeron (single-core), Pentium 4 (single-core), Pentium D (dual-core) and Core 2 Duo (dual-core) desktop processors. You have to make sure that a Socket LGA775 motherboard supports a Pentium D or Core 2 Duo dual-core processor, because some of the earlier Socket LGA775 motherboards cannot run the latest processors made for this socket.
Socket T (also known as Socket LGA775) - http://en.wikipedia.org/wiki/Socket_T
Note that Intel's Core i7 Socket LGA1366 quad-core desktop PC processors were made available in September 2008.
The Socket LGA1156 Core i5 and Core i7 quad-core desktop-PC processors were made available on September 8, 2009.
November 18, 2008. - Intel released three of its new Socket LGA1366 quad-core processors. Here is a good review:
Intel Core i7 - http://www.pcpro.co.uk/reviews/processors/233892/intel-core-i7
And here is the information on the processors on Intel's website:
Intel® Core i7 Processor -
All of the major motherboard manufacturers (Asus, MSI, Gigabyte, Asrock, Intel, Foxconn, etc., release motherboards that support new processors from AMD and Intel when they are released.
User manuals are available from all of those manufacturers, so you can download copies and have a look at what is on offer.
This is how Intel describes the processors on its website: "These processors will feature Intel® Hyper-Threading Technology, also known as simultaneous multi-threading, and are capable of handling eight software "threads" on four processor cores."
Asus made its P6T Deluxe motherboard with the X58 chipset, which has the new LGA1366 processor socket, available to reviewers world-wide.
That motherboard provides new power-saving and overclocking technology. As an optional extra a device known as the OC Palm is available that provides overclocking on-the-fly during gaming or benchmarking. You can see an image of the device attached to a USB port on this page:
New ASUS P6T DELUXE with Super Hybrid Engine Delivers Maximum Overclocking and Energy Efficiency -
"The P6T DELUXE adopts the usage of TurboV - an advanced overclocking tool that utilizes a micro-controller to provide precise overclocking adjustments, and allow users to conveniently adjust the CPU ratio (multiplier)* for instant CPU upgrades for real-time performance enhancements. TurboV can also provide adjustments to the NB voltage, NB-PCIe voltage, CPU PLL voltage and DRAM voltage in 0.02V micro-intervals." - quote for a new story on asus.com that no longer exists.

Core i7: 4-Way CrossFire, 3-way SLI, Paradise? : Tempered Expectations -
"For the first time ever, gamers are being treated to a reasonably priced platform enabling the best that AMD and NVIDIA have to offer." -
Intel's new Socket LGA1336 processors -
Note that the second-generation Core i3, i5 and i7 (Sandy Bridge) processors use Socket LGA1155, which is incompatible with Socket LGA1156. The first generation of those processors use Socket LGA1156.
September 8, 2009. - Intel has released three new quad-core desktop-PC processors - the first Core i5 processor (Core i5-750) and two Core i7 processors (Core i7-860 and Core i7-870), all of which use new Socket LGA1156 platform, manufactured using the latest 45-nanometer (45nm) fabrication process. The new Core i7 processors feature Intel's HyperThreading technology, which effectively allows them to function as eight-core processors, but the Core i5 processor can only function as a non-enhanced quad-core processor. No Extreme Editions of these processors are available, so overclockers are not able to tweak the processors' frequency multipliers; overclocking can only be achieved by increasing the system-bus speed.
As with the previous Socket 1366 Core i7 quad-core processors the new Intel processors have on-chip memory and PCI bus controllers and 8MB of shared Level 3 cache. However, instead of being able to run RAM memory in triple-channel and dual-channel modes as the original Socket 1366 Core i7 processors do, the new processors can only run in dual-channel mode, which means that the motherboards that run them only have to have four memory slots for two sets of identical memory modules running in dual-channel mode, not six memory slots in order to run two sets of three identical memory modules in triple-channel mode.
Because of technological improvements, such as an improved Turbo Mode that adjusts the processor clock speed to boost single-threaded applications when other cores not being used, the new processors have similar performance to the original Core i7 processors, but are being sold at significantly lower prices (L140, excluding VAT, for the Core i5-750 compared to L180, excluding VAT, for the original Socket 1366 Core i7-920). Socket LGA1156 motherboards are also cheaper than Socket LGA1366 motherboards (many are available for below L100). However, since the new processors have a new socket, they cannot be installed in the original Core i7 processors' Socket LGA1366 motherboards. This is a negative feature considering that all of AMD's Phenom II Socket AM3 processors can be installed in the earlier Socket AM2+ motherboards.
Here are reviews of each of the three processors:
Intel Core i5-750 -
Intel Core i7-860 -
Intel Core i7-870 -
AMD's range of Socket AM2 processors were superseded by its Socket AM2+ and Socket AM3 processors.
In November 2007, the AMD Socket AM2+ quad-core processors called the Phenom arrived on the market. Less expensive, triple-core versions were made available later on.
In February 2009, AMD's Socket AM3 triple-core and quad-core Phenom II processors were made available.
AMD's Socket AM2/AM2+ processors have an onboard memory controller that supports the latest DDR2 RAM. The Socket AM3 platform supports DDR3 RAM memory.
For the first time since its take-over of the graphics-chip company, ATI, AMD produced a complete platform, code-named Spider, that consists of a Phenom processor, the 790FX motherboard chipset and the Radeon HD3800 series of graphics cards.
Intel's quad-core processors are really just two dual-core processors in a single package. However, AMD's quad-core processors have all four cores in a single chip.
The Phenom processors and all of the Athlon 64 Socket AM2 processors can be used on either the new Socket AM2+ motherboards or on Socket AM2 motherboards. In other words, in order to run, the Phenom processors do not require a new Socket AM2+ motherboard. They will also run in a Socket AM2 motherboard. A Phenom processor uses Hypertransport 2.0 on an AM2+ motherboard, and Hypertransport 1.0 on a AM2 board. However, a BIOS update is probably be required to run a Phenom processor on an AM2 motherboard.
The single-die, quad-core design involves a greater risk of manufacturing defects resulting in lower yields per silicone wafer. If only one of the four cores is defective, it cannot be sold as a quad-core processor. However, if one of the cores is defective, it is deactivated with the intention in mind of marketing it as a triple-core or tri-core processor. Triple-core versions of both the Phenom and Phenom II processors were made available.
Each of the four processor cores of a Phenom processor possesses its own 512 KB of L2 (Level 2) cache, and all of the cores have access to 2MB of L3 (Level 3) cache, which produces an increase in performance.
The Phenom II processors, which are manufactured on a 45nm fabrication process and which support DDR3 memory, will run in Socket AM2 and AM2+ motherboards. AMD's first ranges of Socket AM3 45nm Phenom II triple-core and quad-core processors were made available in February 2009.
The other advantages of the Spider platform are that it can be upgraded to use up to four graphics cards, and the platform supports the new PCI Express 2.0 graphics standard.
Motherboard manufacturers Asus, MSI, and Gigabyte were at the introduction of the Spider platform in Warsaw to show off their AM2+ motherboards. According to AMD, the MSI K9A2 Platinum (MS-7376) motherboard was the best of the offerings.
February 17, 2009 - AMD has released several new Socket AM3 Phenom II triple-core and quad-core processors, including the triple-core Phenom II X3 720 Black Edition (2.8GHz) and the quad-core Phenom II X4 810 (2.6GHz). AMD has also released a lower-clocked triple-core Phenom II X3 710 (2.6GHz) and OEM-only quad-core Phenom II X4 805 (2.5GHz) and Phenom II X4 910 (2.6GHz) models. These processors are primarily designed to use a Socket AM3 platform, but are backward-compatible with existing Socket AM2+ motherboards. The Phenom II processors use DDR3 RAM memory, but can use DDR2 memory when used in a Socket AM2+ motherboard.
The web is full of interesting information on these new processors. To locate it, you can enter Phenom II as the search query in a web search engine.
AMD's latest range of processors with onboard graphics chips for desktop and laptop PCs are called A-Series Fusion APU, were made available in July 2011. AMD calls its new processors APUs (Accelerated Processing Units), because, containing an onboard graphics chip, they are more than mere CPUs (Central Processing Units). Socket FM1 is the socket provided by desktop PC motherboards for the new processors. Socket FM1 motherboards have also been made available by the major motherboard manufacturers (MSI, Gigabyte, Asus, etc.)
As with some of Intel's latest (first and second generation) Core i3, i5 and i7 processors, AMD's newest range of Series-A Fusion Socket FM1 dual-core and quad-core processors, code-named Lynx for the desktop-PC, use a new FM1 socket and have onboard graphics chips. All of them, unlike Intel's second-generation Core processors of which only some models provide onboard graphics. In tests the new processors have outperformed Intel's Core processors in 3D gaming by a long way. Moreover, with AMD's new processors, it is possible to run an AMD graphics card in tandem with the processor's graphics chip in Crossfire mode to increase performance even more just by using a low-end, inexpensive graphics card and even more by using a high-end graphics card. The Fusion processors support the latest DirectX 11; Intel's Core processors that provide a graphics chip only support DirectX 10. Moreover, the mobile (laptop) versions have much longer battery life than Intel's equivalent processors with onboard graphics. Unlike Intel's Core processors with onboard graphics, which cannot play games without the computer having a graphics card, AMD's new processors are capable of playing games on their own.
