What Is Socket AM2?
AMD means that the processor socket is Socket AM2,940 pins. AMD's Athlon 64 series processors have been popular in the market for more than a year. Due to the integration of memory controllers, the Athlon 64 series processor platform still stays in the DDR era. As early as mid-2004, Intel has begun vigorously promoting DDR2 memory. In this case, AMD introduced its first processor that supports DDRII memory. AM2 uses 90nm SOI process, equipped with 512K L1 cache and 1MB or 2MB L2 cache.

- AMD means that the processor socket is Socket AM2,940 pins. AMD's Athlon 64 series processors have been popular in the market for more than a year. Due to the integration of memory controllers, the Athlon 64 series processor platform still stays in the DDR era. As early as mid-2004, Intel has begun vigorously promoting DDR2 memory. In this case, AMD introduced its first processor that supports DDRII memory. AM2 uses 90nm SOI process, equipped with 512K L1 cache and 1MB or 2MB L2 cache.
- Frequency increase is a difficult problem, and new processes are expected to be introduced
- The core using the Socket AM2 pin is called "F" stepping. It has all the features of the current "E" stepping core. The only difference is that the previous generation supports dual-channel DDR 400 to dual-channel DDR2 800 and adds AMD virtual technology. . Compared with the current "E" stepping core, the "F" stepping core, in addition to the changes in the memory controller and the addition of AMD virtual technology, is obviously the L2 Cache part has been reduced. The process is mature. The L2 Cache part of the Rev F core has been redesigned to reduce the loop (transistor) used to increase speed. In addition, the quality of the "F" stepping core has also been improved. At the same power consumption, the frequency of the previous generation Rev E can be increased by 7%, or the power consumption is reduced by about 7% at the same frequency. It can increase the productivity of the low-power version.
- In terms of the number of transistors, although the number of transistors used in the L2 Cache has been reduced, the number of transistors and core size of the Rev F core have been improved due to the use of DDR2 memory controllers and AMD virtual technology. For example, the Windsor core for dual-core processors has In the previous generation, 233 million was increased to 243 million, and the Die Size was also increased from 199 square millimeters to 220 square millimeters. The overall power consumption has been reduced. Only FX-62 is a special case. It should be mentioned that the overall performance of AMD AM2 products is improved and the power consumption is reduced. L2 cache, manufactured by AMD's Fab 30 factory in Dreseden, Germany.
- According to AMD's plan, new generation processor cores including Windsor, Orleans and Manila will start to use Socket AM2 specifications, 90nm process, and also support dual-channel DDR2 memory, including Athlon64 X2 dual-core processors using Windsor core and Orleans core Athlon 64 all have Pacifica virtualization technology built in, while Manila core Sempron processor does not support this technology. Below, let us briefly introduce the three new series processors of AMD.
- ket940 interface (different from earlier 940 pins);
- 2. Full support for DDR2 memory;
- 3. Lower power consumption;
- 4. Virtualization technology;
- 5. New motherboard chip support.
- The AMD processor line launched the AM2 interface processor in 2006, which not only unified the 754, 939, and 940 platforms, but also added support for DDR2 800MHz memory, supported virtualization technology, and effectively controlled power consumption. The AM2 interface uses a 940-pin design, but this 940-pin is not the same as the 940-pin. The AM2 interface and the 940-pin Operan processor are not compatible because the built-in
- AMD raises design of new generation desktop processor interface SocketAM2
- The concept of unified high-, middle- and low-end product interfaces has been developed, and sufficient design and upgrade space has been reserved for future 65nm process dual-core and even quad-core processor products, and the upgrade potential is huge. AMD's latest Athlon64, Athlon 64 X2, Athlon 64FX, Sempron, and 1XX series Opteron processors will all use this interface.
- AM2 interface processor : includes dual-core Athlon64 x2 / Athlon64FX processor codenamed Windsor, single-core Athlon64 processor codenamed Orleans, and low-end Sempron processor codenamed Manila. Windsor and Orleans cores will support AMD virtualization technology and support DDR2 memory. Although the low-end Manila core Sempron does not support virtualization technology, the built-in memory controller can support dual-channel DDR2. In this way, high-end, low-end processors use a unified interface, so users do not need to replace the motherboard when upgrading the CPU. Sock

- The product has changed in the following areas:
- New version built into the processor
- Memory controller, corresponding to dual-channel DDR2 SDRAM configuration, of which Athlon64FX and Athlon64X2 support DDR2-667 / 800, Athlon64 and Sempron support up to DDR2-667;
- The correspondence between the processor's model nominal value and frequency has changed to reflect the performance improvement brought by the dual-channel DDR2 memory; in addition to Sempron, other Socket AM2 processors have added AMD VirtualzationTechnology support; the interface is unified to 940pin Socket AM2, The processor package size remains the same, but the pins are not compatible with Socket939; the form of the standard heat sink mounting bracket has changed, and some Socket 754/939 heat sinks will no longer be usable.
- AM2 Family Portrait
- The AM2 interface processor series is divided into four grades, from the highest to the lowest Athlon 64 FX-62, the high-end Athlon64 X2 3800 to 5000, the mainstream Athlon 64 3500 to 3800, and the low-end Sempron 3000 to 3600. Socket 939 and Socket 754 interface processors. All SocketAM2 processors have integrated DDR2 memory controllers.

- DDR2: Doubling memory performance
- The AM2 platform is based on 64-bit compatible 32-bit technology, and its HT bus bandwidth reaches 8GB / s, which is the biggest feature of the entire architecture. Another new feature of the most concerned AM2 is the integrated DDR2 memory controller. Compared with Intel's current series of processors, the advantage of AMD lies in the processor's integrated memory controller. From the original DDR to the DDR2 controller, the memory bandwidth of the AM2 processor has been greatly improved. FX series and X2 dual-core series can support up to DDR2800, memory bandwidth up to 12.8GB / s, single-core Athlon 64, Sempron processors can support DDR2667, bandwidth up to 10.66GB / s, so bandwidth is relatively high. We also clearly remember that when Intel started pushing DDR2 memory specifications in 2004, AMD did not follow up. They concluded that the best time to support DDR2 must be that the performance of DDR2 must exceed the performance of current DDR, and the price of DDR2 should be close to the original Mainstream products, DDR2 supply should be sufficient. Therefore, until the DDR2 memory market began to heat up, Microsoft's next-generation operating system, Windows Vista, will also be officially released within one year. Users' demand for DDR2 began to increase. AMD believes that the time is ripe and launched the AM2 platform technology as planned. Some memory controllers of AMD's past products are on the chipset. The memory performance that has an important impact on overall performance does not depend on the design of the processor. It is also closely related to the design of the chipset. Now the entire AM2 platform, including Sempron, Athlon, etc., its memory controller is in the processor, which has the biggest benefit, the overall bandwidth will be very high, the highest bandwidth can reach 20.8GB / s (system bus Bandwidth + memory bandwidth).
- Power consumption: more optimized design
- More and more users are paying attention to the issue of computer power consumption, and the power consumption design of the processor also represents the technical strength of the manufacturer. The AM2 platform released by AMD this time includes two types of processors, one is a standard type; the other is a low-power product. For mainstream markets
- AM2 processor
- AMD's lowest power consumption products are only 35W, even lower than the power consumption of some old mobile processors, so processor noise can be very low, it can be said that low power consumption brings many benefits to the entire industry. Reducing power consumption improves performance per watt. AMD has released PCs with similar low-power products to some OEM customers around the world. The size of the PC is very, very small. As we all know, the DVD player playing at home has very low noise, there is no fan in it, and we have a fan in our PC. One of the major disadvantages of PCs entering the home is the problem of heat dissipation and power consumption. Easy to extend the PC to the field of home appliances. According to AMD's official test data, the 65W dual-core processor improves performance per watt by about 37% compared to previous products, and 35W products can increase 54%. In addition, various PC manufacturers, including chassis manufacturers and OEM manufacturers, can design smaller chassis and save power. However, for the FX processor pursuing extreme performance, the power consumption has been increased from the original 104W to 110W to the AM2 platform and increased to 121W. However, it does not affect some applications, because the FX processor is the top processor. It pays more attention to performance improvement, not just power consumption.
- Virtualization: Future Technology Trends for PCs
- When everyone thinks that DDR2 should be the most important feature of AM2 processor, AMD's product manager tells us that AMD virtualization technology is the most important technology of AM2. When AM2 was released, the core was not DDR2 or low power consumption, but virtualization technology. Virtualization technology is currently widely used in the server field, but in fact this is the trend of PC development in the future. What are the benefits of virtualization technology? We can have many threads in the virtualization technology, each thread has its own virtual machine, this
- AM2 processor
- There are many benefits to virtualization technology. Assuming that both PCs are hosts that support virtualization technology, you can see that multiple sets of application systems are running at the same time. Assuming this machine crashes, there is no problem, it will not cause other systems to crash. In a commercial environment, the use of virtualization technology can even form a huge grid.
- AM2 unifies the entire AMD platform
- For the average consumer, AM2 has the most obvious benefit-no more painful choices in different interfaces. At the beginning, the unified SocketA interface was divided into Socket 754, Socket 939, and Socket940. Now it is back to the system again.
- AM2. AMD has gradually replaced the currently popular Socket754 / 939 interface, and AM2 has become the unified interface of the new generation processor of the AMD platform. Entry-level, mainstream, high-performance all use the same platform and the same interface. Although there will be a transition period for AMD processors in the market, the original Socket 754 and Socket 939 products will coexist in the market with AM2 products, but for new users, the AM2 platform is more recommended, DDR2, virtualization, Support for Vista will make AM2 the new mainstream platform for AMD.
- chipset
- Chipset manufacturers have been fond of the AMD platform since the era of the K8 processor. Especially after Intel launched the platform strategy, the survival space of chipset manufacturers has become smaller and smaller. Therefore, for now, chipset manufacturers are more inclined to follow AMD. This time AMD s release of the AM2 unified processor architecture has also attracted great attention from chipset manufacturers, and have taken the opportunity to launch related products. NVIDIA almost launched on AM2
