AMD’s dual-core processors are the dual-core Opteron series and the new Athlon 64 X2 series processors. The Athlon 64 X2 is a family of desktop dual-core processors designed to compete with the Pentium D and Pentium Extreme Edition.
AMD's Athlon 64 X2 is a combination of two core Atomon 64 processors. Each core has a separate 512KB (1MB) L2 cache and execution unit. In addition to one more core, there is no major architectural change from the current Athlon 64 architecture.
Most of the specifications and functions of the dual-core Athlon 64 X2 are not different from the familiar Athlon 64 architecture. In other words, the newly introduced Athlon 64 X2 dual-core processor still supports the 1GHz HyperTransport bus and has built-in support for dual channels. Set up a DDR memory controller.
Unlike Intel dual-core processors, the two cores of the Athlon 64 X2 do not need to be coordinated with each other via the MCH. AMD provides a technology called System Request Queue inside the Athlon 64 X2 dual-core processor. Each core puts its request in SRQ at work, and the request will Is sent to the appropriate execution core, that is to say all the processing is completed within the scope of the CPU core, and does not require the use of external devices.
For the dual-core architecture, AMD's approach is to integrate the two cores in the same silicon core, while Intel's dual-core processing approach is more like simply the two cores together. Compared with Intel's dual-core architecture, AMD dual-core processor systems do not have the problem of transmission bottlenecks between the two cores. So in this respect, the Athlon 64 X2 architecture is significantly better than the Pentium D architecture.
Although compared with Intel, AMD does not have to worry about power consumption and fevers like the Prescott core, but it also needs to consider ways to reduce power consumption for dual-core processors. For this reason, AMD did not use a method to reduce the main frequency. Instead, it used the so-called Dual Stress Liner strained silicon technology in its Athlon 64 X2 processor manufactured on a 90-nm process. Using SOI technology, it can produce higher performance. Power-efficient transistors.
AMD's Athlon 64 X2 processor brings users the most cost-effective benefits, that is, do not need to replace the platform to use the newly launched dual-core processor, as long as the old motherboard to upgrade the BIOS on it, and Intel dual-core processing Compared to the practice that the device must be replaced with a new platform, upgrading the dual-core system will save a lot of money.
