Differentiation AMD and Intel Processor

AMD Sempron
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.
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.
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.
AMD Opteron
The AMD Opteron processor offers simultaneous 32- and 64-bit computing, using AMD's Direct Connect Architecture. It's designed to run existing 32-bit applications and offer simplified migration path to 64-bit computing. The AMD Opteron processor is available in 1 to 8-way servers and 1 to 4-way workstation solutions.

Intel Celeron D
The Intel Celeron D is a value-priced processor. The Celeron D processors include a larger integrated L2 cache and faster processor system bus when compared to Celeron processors. Celeron processors are available at speeds ranging from 1 GHz to 2.80 GHz. Celeron D processors offer a 533 MHz multi-transaction processor system bus with 256-KB Level 2 cache. Intel added Extended Memory 64 Technology to its value oriented Celeron D line.
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).
Intel Pentium D
Intel Pentium D processors are designed to provide users with more power while running multiple applications (for example, editing videos while downloading files). Pemtium D processors offer 2x1MB L2 cache, clock speeds ranging from 2.80 GHz to 3.20 GHz and an 800 MHz frontside bus. These processors are dual-core and offer Intel Extended Memory 64 Technology as well.
Intel Pentium 3 (Pentium III)
Intel builds on the technology it developed with the Pentium II microprocessors. The Pentium III processor comes with a Synchronized Dynamic Random Access Memory (SDRAM), allowing for an extremely fast transfer of data between the microprocessor and the memory. Pentium III's offer enhanced multimedia and 3D performance with 100 MHz front-side bus speed, a muti-transaction system bus, and MMX support.
