Sempron has been the marketing name used by AMD for several different entry level desktop CPUs, using several different technologies and CPU socket formats. The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. In Personal computers the Front Side Bus ( FSB) is the bus that carries data between the CPU and the northbridge.

The Sempron replaced the AMD Duron processor and competes against Intel's Celeron D processor. The AMD Duron was an X86 -compatible Computer processor manufactured by AMD. The Celeron brand is a range of X86 CPUs from Intel targeted at budget/value Personal computers €”with the motto "delivering great quality

AMD coined the name from the Latin semper, which means "always, everyday", to denote that the Sempron was the right processor for everyday computing [1].

History and features

The first Sempron CPUs were based on the Athlon XP architecture using the Thoroughbred or Thorton core. Athlon is the brand name applied to a series of different X86 processors designed and manufactured by AMD. These models were equipped with the Socket A interface, 256 KiB L2 cache and 166 MHz Front side bus (FSB 333). Socket A (also known as Socket 462) is the CPU socket used for AMD processors ranging from the Athlon Thunderbird to the A kibibyte (a contraction of ki lo bi nary byte) is a unit of Information or Computer storage, established by the International In Personal computers the Front Side Bus ( FSB) is the bus that carries data between the CPU and the northbridge. Thoroughbred cores natively had 256 KiB L2 cache, but Thortons had 512 KiB L2 cache, half of which was disabled and could sometimes be reactivated by bridge modification. Later, AMD introduced the Sempron 3000+ CPU, based on the Barton core with 512 KiB L2 cache. From a hardware and user standpoint, the Socket A Sempron CPUs were essentially identical to Athlon XP desktop CPUs with a new brand name. AMD has ceased production of all Socket A Sempron CPUs.

The second generation (Paris/Palermo core) was based on the architecture of the Socket 754 Athlon 64. Socket 754 is a CPU socket originally developed by AMD to succeed its Athlon XP platform (Socket 462 also referred to as Socket A) The Athlon 64 is an eighth-generation AMD64 architecture Microprocessor produced by AMD, released on Some differences from Athlon 64 processors include a reduced cache size (either 128 or 256 KiB L2), and the absence of AMD64 support in earlier models. Apart from these differences, the Socket 754 Sempron CPUs share most features with the more powerful Athlon 64, including an integrated (on-die) memory controller, the HyperTransport link, and AMD's "NX bit" feature. The memory controller is a chip on a computer's Motherboard or CPU die which manages the flow of data going to and from the memory. The NX bit, which stands for No eXecute, is a technology used in CPUs to segregate areas of memory for use by either storage of processor instructions (or code

In the second half of 2005, AMD added 64-bit support (AMD64) to the Sempron line. x86-64 is a Superset of the x86 instruction set architecture. Some journalists (but not AMD) often refer to this revision of chips as "Sempron 64" to distinguish it from the previous revision. AMD's intent in releasing 64-bit entry-level processors was to extend the market for 64-bit processors, which at the time of Sempron 64's first release, was a niche market. A niche market is a focused targetable portion (subset of a market

In 2006, AMD announced the Socket AM2 and Socket S1 line of Sempron processors. The Socket AM2, renamed from Socket M2 (to prevent using the same name as Cyrix MII processors is a CPU socket designed by AMD for desktop Socket S1 is the CPU socket type used by AMD for their Turion 64, Athlon 64 Mobile and later Sempron processors which debuted These are functionally equivalent to the previous generation, except they have a dual-channel DDR2 SDRAM memory controller which replaces the single-channel DDR SDRAM version. DDR SDRAM ( double data rate synchronous dynamic random access memory) is a class of memory Integrated circuit used in Computers It achieves nearly twice The TDP of the standard version remains at 62 W (watts), while the new "Energy Efficient Small Form Factor" version has a reduced 35 W TDP. The Thermal Design Power (TDP (sometimes called Thermal Design Point) represents the maximum amount of power the cooling system in a computer is required to dissipate The Socket AM2 version also does not require a minimum voltage of 1. 1 volts to operate, whereas all socket 754 Semprons with Cool'n'Quiet did. In 2006, AMD was selling both Socket 754 and Socket AM2 Sempron CPUs concurrently. In the middle of 2007 AMD appears to have dropped the 754 line and is shipping AM2 and S1 Semprons.

Future plans

In 2008, Sempron-branded implementations of the Stars microarchitecture are expected to become available, based on the Rana core. The AMD K10 is AMD 's latest Microprocessor architecture. Though there were once reports that the K10 had been cancelled, the first third-generation These are expected to be dual-core processors without L3 cache. Initial clock rates will be between 2. 1 GHz and 2. 3 GHz. The Rana Semprons will feature HyperTransport 3. 0 support and will be packaged for the Socket AM2+ form factor, although they are expected to function in Socket AM2 motherboards, albeit without support for HyperTransport 3. Socket AM2+ is a CPU socket, which is the immediate successor to Socket AM2 that is currently used by several AMD Processors such as Athlon The Socket AM2, renamed from Socket M2 (to prevent using the same name as Cyrix MII processors is a CPU socket designed by AMD for desktop 0 enhancements.
