Names of the processor cores:
|
The AMD Athlon 64 X2 is a microprocessor for computers . It belongs to the K9 generation and is the dual core version of the Athlon 64 .
Since mid-2007, AMD has also been offering notebook processors with the name Athlon 64 X2 . Although these mobile processors are related to the Athlon 64 X2 for desktops, they are based on a different processor core and were only offered for a different processor socket.
General
The Athlon 64 X2 contains two processor cores and behaves in terms of software like a two-processor system. This means that an increase in performance can only be achieved when several programs are used at the same time , unless specially adapted programs are used.
The processor was designed for Socket 939 and Socket AM2 and has a two-channel memory controller ( DDR for Socket 939, DDR2 for Socket AM2) that is shared by both cores. The processor also served as the basis for AMD LIVE! .
production
AMD also offered special versions of the respective processor cores with partially deactivated L2 cache. The reason for this was that it often happened during production that part of the L2 cache was defective. Since the processor was actually functional, the defective part of the cache was deactivated.
There have also been cases in which a defect in one of the processor cores deactivated it and the processor was then sold as a single core processor Athlon 64 or Athlon .
Black Edition
With the Athlon 64 X2 5400+ (based on the Brisbane core), AMD offered a so-called "Black Edition" which, like the Athlon 64 FX, has an open-top multiplier. This makes overclocking relatively easy . AMD aimed directly at the target group of hardware enthusiasts with this affordable product. The Black Edition processors were manufactured in the new G2 stepping .
However, the addition "Black Edition" does not automatically mean a freely selectable multiplier. The Athlon 64 X2 6400+, which was also available as a "Black Edition", does not have this feature. However, AMD also appealed to enthusiasts with this processor because it was AMD's fastest desktop CPU for a long time until the appearance of the K10 processors.
successor
In 2009 the Athlon 64 X2 processors were replaced by processors based on the K10 architecture and withdrawn from the market. Until then, the Athlon 64 X2 and Athlon X2 processors were offered in parallel with the new AMD Phenom and AMD Athlon II processors.
Model data socket 939
All processors for socket 939 have a memory controller with two channels (128 bit, dual-channel operation ) for DDR-SDRAM .

Energy classes
The AMD Athlon 64 X2 was manufactured in different energy classes. A differentiation between the models is only possible on the basis of the OPN . This number is located on the processor housing under the processor designation.
Beginning of the OPN | maximum power consumption | Energy class |
ADDxxxxxxxxxx | 35 watts | EE SFF |
ADHxxxxxxxxxx | 45 watts | BE |
ADOxxxxxxxxxx | 65 watts | EE |
ADAxxxxxxxxxx | 89 watts | default |
ADXxxxxxxxxxx | 125 watts | SE |
Abbreviations
- EE : E nergy E fficient means that the CPU consumes less power in comparison and therefore the power loss is lower.
- SFF : S mall F orm F actor means that the power loss has been significantly reduced again compared to EE. The CPU thus requires less complex cooling and is therefore suitable for smaller computer cases.

Incompatibilities with Windows 8.1 / 10 64 bit
The versions of the Athlon 64 / X2 and Sempron for socket 939/940 do not support the so-called CMPXCHG16b instructions, which are required by Windows 8.1 / 10 x64. For the 64-bit versions of Windows 7 and 8.0, Microsoft programmed a software workaround into the Windows kernel, which was omitted from Windows 8.1 for security reasons. As an alternative to a modern Windows, operation with a 32-bit variant is possible. However, only a maximum of 4 GB RAM can be addressed with it. Processors for socket AM2 and newer support the required instructions.
