Frustrated by staring at the hourglass icon as soon as you try to work on more than three programs at once, especially when you are working with digital media? Increase your performance by up to 80% with the AMD Athlon 64 X2 dual core processor. Work or play with multiple programs without any stalling or waiting. Dual-core technology is like having two processors, and two working together is better and faster than one working alone. Do more in less time with the AMD Athlon 64 X2 dual-core processor. From the Manufacturer 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 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.
