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.

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/Thorton core. These models were equipped with the Socket A interface, 256 KiB L2 cache, and 166 MHz Front side bus (FSB 333). Thoroughbred cores natively had 256KiB L2 cache, but Thortons had 512KiB 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 renamed Athlon XP desktop CPUs. AMD has ceased production of all Socket A Sempron CPUs. Athlon is the brand name applied to a series of different x86 processors designed and manufactured by AMD. The original Athlon, or Athlon Classic, was the first seventh-generation x86 processor and, in a first, retained the initial performance lead it had over Intels competing processors for a significant... Socket A (also known as Socket 462) is the CPU socket used for AMD flagship processors ranging from the Athlon K7 to the Athlon XP 3200+, and AMD budget processors including the Duron and Sempron. ... According to the International Electrotechnical Commission a kibibyte (a contraction of kilo binary byte) is a unit of information or computer storage. ... In computers, the front side bus (FSB) or system bus is the physical bi-directional data bus that carries all electronic signal information between the central processing unit (CPU) and other devices within the system such as random access memory (RAM), video cards, PCI expansion cards, hard disks, the memory...


The second generation (Paris/Palermo core) was based on the architecture of the Socket 754 Athlon 64. 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 bus, and AMD's "NX bit" feature. Socket 754 is a CPU socket originally developed by AMD to succeed its powerful 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 September 23, 2003[1].

In the second half of 2005, AMD added 64-bit support (AMD64) to the Sempron line. 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. AMD64 Logo AMD64 (also x86-64 or x64) is a 64-bit microprocessor architecture and corresponding instruction set designed by Advanced Micro Devices. ... A niche market is a focused, targetable portion of a market sector. ...


In 2006, AMD announced the Socket AM2 line of Sempron processors. 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. 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 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. As of 2006, AMD sells both Socket 754 and Socket AM2 Sempron CPUs concurrently.

It may contain preliminary or speculative information, and may not reflect the final specification of the product.

In Q2 2007, the Sempron will migrate to the 65 nm SOI process, under the code name "Sparta". These new Semprons will have the same 35 W TDP of the current "Energy Efficient SFF" Semprons. They will remain single-core. [2] Image File history File links Current_event_marker. ...


In Q4 2007, Sempron-branded implementations of the Stars microarchitecture are expected to become available, based on the Rana core. 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 3.0 enhancements.[3] The AMD K10 is AMDs next generation of processors. ...

Sempron - Wikipedia, the free encyclopedia (580 words)
Sempron is, as of 2006, AMD's entry level desktop CPU, replacing the Duron processor and competing against Intel's Celeron D processor.
The first Sempron CPUs were based on the Athlon XP architecture using the Thoroughbred/Thorton core.
Later, AMD introduced the Sempron 3000+ CPU, based on the Barton core (512 KiB L2-cache.) From a hardware and user standpoint, the Socket-A Sempron CPUs were essentially renamed Athlon-XP desktop CPUs.
TrustedReviews - AMD Sempron 3100+ (514 words)
The Sempron 3100+ does however lack 64bit support, so don’t expect to be able to run 64bit Windows XP on it when it arrives.
First of all, let’s clarify a few things; the Sempron 3100+ is only available for Socket-754 and not the newer Socket-939, which seems strange, especially when you consider that AMD will move all its Athlon 64s to the new platform.
A wild guess would be that the Sempron would perform better with dual channel memory and AMD is trying to prevent it from competing with the Athlon 64.
