The introduction of the F3 stepping then saw several models with 1В MB L2 cache per core as production refinements resulted in an increased yield. The Athlon 64 X2 with 512 KB per core, known as 3800+, 4200+, 4600+, and 5000+, were produced in far greater numbers. This led to only a small production number of the Socket-AM2 Athlon 64 X2 with 1В MB L2 cache per core, known as 4000+, 4400+, 4800+, and 5200+. In the middle of June 2006 AMD stated that they would no longer make any non-FX Athlon 64 or Athlon 64 X2 models with 1В MB L2 caches. This lower yield makes the X2 more expensive to produce than the single-core processor. These size requirements necessitate a more complex fabrication process, which further adds to the production of fewer functional processors per single silicon wafer.

As a result, a larger area of silicon must be defect free. The 65В nm Athlon 64 X2 with only 512 KB L2 per Core reduced this to 118В mmВІ with 221 million transistors compared to the 65В nm Athlon 64 with 77.2В mmВІ and 122 million transistors. The 1В MB L2 cache 90В nm Athlon 64 X2 processor is 219В mmВІ in size with 243 million transistors whereas its 1В MB L2 cache 90В nm Athlon 64 counterpart is 103.1В mmВІ and has 164 million transistors. Having two cores, the Athlon 64 X2 has an increased number of transistors. In the consumer segment of the market, the X2 improves on the performance of the original Athlon 64, especially for multi-threaded software. This is mostly due to the high overhead caused by constantly switching threads, and could potentially be improved by adjustments to operating system scheduling code. Intense multitasking processes have sped up by considerably more than twice. Multitasking also runs a sizable number of threads. These applications can reach almost twice the performance of a single-core Athlon 64 of the same specifications. High TLP applications currently correspond to server and workstation situations more than the typical desktop.

#AMD ATHLON DUAL CORE 5000B PROFESSIONAL#

Programs often written with multiple threads and able to use dual-cores include many music and video encoding applications, and especially professional rendering programs.

Some programs are currently written for only one thread, and thus cannot use the processing power of a second core. The need for TLP processing ability depends on the situation to a great degree, and some situations benefit from it far more than others. By placing two cores on the same die, the X2 effectively doubles the TLP over a single-core Athlon 64 of the same speed. The ability of processors to execute multiple threads simultaneously is called thread-level parallelism (TLP).

#AMD ATHLON DUAL CORE 5000B SOFTWARE#

The primary benefit of dual-core processors (like the Athlon 64 X2) over single-core processors is their ability to process more software threads at the same time. The name was also used for K10 based budget CPUs with two cores deactivated.ДЇurther information: Multi-core processor The Athlon X2 processors feature reduced thermal design power (TDP) of 45 Watt (W). In June 2007, AMD released low-voltage variants of their low-end 65В nm Athlon 64 X2, named ' Athlon X2'. The Athlon 64 X2 can decode instructions for Streaming SIMD Extensions 3 ( SSE3), except those few specific to Intel's architecture. The initial versions are based on the E stepping model of the Athlon 64 and, depending on the model, have either 512 or 1024 KB of L2 cache per core. It was designed from scratch as native dual-core by using an already multi-CPU enabled Athlon 64, joining it with another functional core on one die, and connecting both via a shared dual-channel memory controller/north bridge and additional control logic.

The Athlon 64 X2 is the first native dual-core desktop central processing unit (CPU) designed by Advanced Micro Devices (AMD).
