Introduction

Take multi-tasking to a whole new level with the AMD Athlon™ 64 X2 Dual-Core Processor. The AMD Athlon 64 X2 Dual-Core processor puts the power of dual-core technology on the desktop. Dual-core processors contain two processing cores, residing on one chip, that perform calculations on two streams of data, thereby increasing efficiency and speed while running multiple programs and the new generation of multi-threaded software.

For the end-user this means a significant increase in response and performance when running multiple applications simultaneously. The AMD Athlon™ 64 X2 Dual-Core processor outperforms the highest-performing AMD Athlon™ 64 4000+ single-core processor on multi-tasking benchmarks by up to 30%.

Better Multi-Tasking Means Increased Office Productivity
Productivity in today’s workplace requires smooth, efficient and seamless multi-tasking. The AMD Athlon 64 X2 Dual-Core processor delivers TRUE multi-tasking, allowing users to switch from one program to another without pausing for the computer to catch up and reducing annoying processing pauses. The end result is an increase in office productivity performance of 22% on average.

Setting the Pace in Digital Media
Digital media software demands simultaneous processing of data streams, the perfect use for the incredible multi-tasking power of the AMD64 dual-core technology. Dual-core technology is like having two processors working together, each one taking care of different applications, so power-users actually experience greater performance when multiple applications are running. Digital media enthusiasts can usher in the next generation of digital media software for amazing high-definition video and photo editing, content creation, and audio mixing. With the AMD Athlon™ 64 X2 Dual-Core processor, your PC will perform up to 80% faster than a single-core AMD Athlon™ 64 4000+ processor on the latest power-hungry digital media software applications.

Smooth and Efficient Upgrades
Additionally, the elegant design of the AMD64 architecture allowed for the planning of dual-core processors from the ground up, which means that the AMD Athlon™ 64 X2 Dual-Core processor is designed to fit in the same 939-pin infrastructure as single-core processors. All that is required is a BIOS update, saving our partners the costs of redesigns and obsolete inventory.

All the Proven Benefits of AMD64 Technology
Enhanced Virus Protection with Windows® XP Service Pack 2
Enhanced Virus Protection is a feature of AMD64 technology. Enhanced Virus Protection feature in AMD64 processors, in conjunction with certain operating systems help to prevent the spread of certain viruses, like MSBlaster and Slammer, significantly reducing the cost and down-time associated with similar viruses and improving the protection of computers and personal information against certain PC viruses1.

AMD Athlon 64 Processor Architecture Performance
HyperTransport™ technology can increase overall system performance by removing I/O bottlenecks, increasing system bandwidth, and reducing system latency. A fully integrated DDR memory controller helps speed access to memory by offering the processor a direct connection to the main memory. As a result, end users can enjoy quicker application loading and extraordinary application performance.

Ready for the 64-bit future
Like all the processors in the AMD Athlon 64 family, the AMD Athlon 64 X2 Dual-Core processor is designed for people who want to stay at the forefront of technology and for those who depend on their PCs to keep them connected, informed, and entertained. Systems based on AMD Athlon 64 processors are able to deliver leading-edge performance for demanding productivity and entertainment software today and in the future.

With AMD64 technology, the AMD Athlon 64 processor is fully compatible with existing software, while enabling a seamless transition to 64-bit applications. Both 32- and 64-bit applications can run virtually simultaneously and transparently on the same platform. AMD64 technology enables new, cinematic computing experiences and capabilities, in addition to increased performance. AMD64 technology allows end users to take advantage of new innovations such as real-time encryption, more life-like games, accurate speech interfaces, cinema-quality graphic effects, and easy-to-use video and audio editing.
