AMD & Intel Processor Lineups

It never fails. Just after you upgrade your CPU, Intel or AMD announces a new processor, pushing technology to new limits — at least its next processor.

To make things even more muddled, AMD and Intel each offers multiple families of processors ranging from those designed for value-oriented family PCs to powerhouse CPUs designed to run most tasking 3D games smoothly. Added into the mix are a host of additional featuresis as well as a new selection of dual-core processors designed for 32-bit or 64-bit computing.

If you find yourself looking through computer store flyers and wondering exactly what an "Athlon 64 X2" is or what the difference between a Pentium 4 and a Pentium D is, then this is a good place to start. We provide an overview of some of the newer and more common families of processors from Intel and AMD.

To make understanding processor technology a little easier, you can use our "Key Terms" list to decipher some of the technical processor lingo, view reviews and specifications for each type of processor, and, of course, check out the links page to follow-up for more information.

The AMD Sempron processor is designed to meet the needs of home and business PC users. AMD Sempron processors are 32-bit and offer capabilities that include HyperTransport technology, up to 512K total high-performance cache, advanced 333Mhz frontside bus and an integrated DDR memory controller.

Sempron 3400+ Processor Review
Review by SharkyExtreme - "The main part of the Sempron market appeal is related to its low price and high value, and even though the Sempron 3400+ is the top performer in the AMD entry-level line, relative pricing actually took a slight dip."

AMD Athlon 64 X2 Dual-Core

The AMD Athlon 64 X2 Dual-Core processor contains two processing cores, residing on one chip, which increases efficiency and speed while running multiple programs and multi-threaded software. It enables a seamless transition from 32-bit to 64-bit applications. Both 32- and 64-bit applications can run virtually simultaneously and transparently on the same platform.

Athlon 64 X2 3800+ Processor ReviewReview by SharkyExtreme - "The Athlon 64 X2 processors are the first true dual core processors for the desktop, and compared to the Intel Pentium D/Pentium EE design, offer a more streamlined and forward-thinking architecture."

AMD Athlon 64

AMD64 provides full support for x86 code base for 32-bit computing and is ready for 64-bit applications. AMD64 technology doubles the number of processor registers and increases the system memory addressability.

Intel Pentium 4

The Intel Pentium 4 processor family supporting Hyper-Threading Technology (HT Technology) is best-suited to desktop PCs and entry-level workstations. The Pentium 4 processor is designed to deliver performance across applications and uses where end-users can appreciate and experience the performance. These applications include Internet audio and streaming video, image processing, video content creation, games, multimedia and multitasking user environments.

Pentium 4 Extreme Edition

The Intel Pentium 4 processor Extreme Edition supporting HT Technology features 3.46 GHz with 2 MB of L3 cache and 3.73 GHz with 2 M of L2 cache to offer high levels of performance targeted specifically for high-end gamers and computing power users. It provides flexibility for future applications that support both 32-bit and 64-bit computing with Intel Extended Memory 64 Technology and is a dual-core processor (two physical cores in one processor support better system responsiveness and multi-tasking).

Pentium 4 6x Series

The Intel Pentium 4 6x series offers 2MB L2 Cache and clock speeds of 3 to 3.80 GHz. Intel Extended Memory 64 Technology is available on the 600x processors. This provides flexibility for future applications that support both 32-bit and 64-bit computing.

Pentium 4 5x Series

The Intel Pentium 4 5x series offers 1MB L2 Cache and clock speeds of 2.80 to 3.80 GHz. Intel Extended Memory 64 Technology is available on the 600x processors is available only on some of the 5x models (571, 561, 551, 541, 531, and 521).

Did You Know...
The observation made in 1965 by Gordon Moore, co-founder of Intel, that the number of transistors per square inch on integrated circuits had doubled every year since the integrated circuit was invented. Moore's Law predicts that this trend would continue for the foreseeable future. In subsequent years, the pace slowed down a bit, but data density has doubled approximately every 18 months, and this is the current definition of Moore's Law, which Moore himself has blessed. (Moore's Law)

Key Terms To Understanding Processors
