| The Athlon 64 X2 is the first dual-core desktop CPU designed by AMD. It was designed from scratch as native dual-core by using an already multi-CPU enabled Athlon 64, joining information technology with another functional core on one die, and connecting both via a shared dual-channel memory controller/northward bridge and additional control logic. The initial versions are based on the E-stepping model of the Athlon 64 and, depending on the model, take either 512 or 1024 KB of L2 Enshroud per core. The Athlon 64 X2 is capable of decoding SSE3 instructions (except those few specific to Intel's architecture). In June 2007, AMD released low-voltage variants of their depression-end 65 nm Athlon 64 X2, named "Athlon X2". [1] The Athlon X2 processors feature reduced TDP of 45 W. [two] The name was besides used for K10 based budget CPUs with ii cores deactivated. Contents - i Multithreading

Multithreading Further data: Multi-core (computing) The benefit of dual-core processors similar the X2 is their ability to procedure more software threads at the same time. The ability of processors to execute multiple threads simultaneously is called thread-level parallelism (TLP). By placing two cores on the same die, the X2 effectively doubles the TLP over a single-cadre Athlon 64 of the same speed. The demand for TLP processing capability is dependent on the situation to a great degree, and certain situations benefit from it far more than others. Certain programs are currently just written with ane thread, and are therefore unable to utilize the processing power of the second core. Programs oftentimes written with multiple threads and capable of utilizing dual-cores include many music and video encoding applications, and particularly professional rendering programs. Loftier TLP applications currently stand for to server/workstation situations more than the typical desktop. These applications tin realize nearly twice the functioning of a single-core Athlon 64 of the same specifications. Multi-tasking besides runs a sizable number of threads; intense multi-tasking scenarios take really shown improvements of considerably more than two times. [iii] This is primarily due to the excessive overhead acquired by constantly switching threads, and could potentially exist improved past adjustments to operating organisation scheduling code. In the consumer segment of the market likewise, the X2 improves upon the performance of the original Athlon 64, especially for multi-threaded software applications. Manufacturing costs Having two cores, the Athlon 64 X2 has an increased number of transistors. The one MB L2 cache 90 nm Athlon 64 X2 processor is 219 mm² in size with 243 million transistors [iv] whereas its 1 MB L2 cache ninety nm Athlon 64 counterpart is 103.1 mm² and has 164 million transistors. [5] The 65 nm Athlon 64 X2 with just 512 KB L2 per Core reduced this to 118 mm² with 221 1000000 transistors compared to the 65 nm Athlon 64 with 77.two mm² and 122 million transistors. Every bit a outcome, a larger area of silicon must exist defect complimentary. These size requirements necessitate a more complex fabrication process, which further adds to the product of fewer functional processors per single silicon wafer. This lower yield makes the X2 more expensive to produce than the single-cadre processor. In the eye of June 2006 AMD stated that they would no longer make any non-FX Athlon 64 or Athlon 64 X2 models with one MB L2 caches. [6] This led to only a small production number of the Socket-AM2 Athlon 64 X2 with i MB L2 cache per core, known equally 4000+, 4400+, 4800+, and 5200+. The Athlon 64 X2 with 512 KB per core, known as 3800+, 4200+, 4600+, and 5000+, were produced in far greater numbers. The introduction of the F3 stepping and then saw several models with 1 MB L2 cache per core as production refinements resulted in an increased yield.
