Athlon 64 X2 4000+ Details

The AMD Athlon 64 X2 4000+ represents a significant step in the evolution of dual-core desktop processors, offering a more balanced performance profile compared to its single-core predecessors. Launched in December 2006, this processor is built on AMD's Windsor core, part of the Athlon 64 X2 family, and operates at a base frequency of 2.1 GHz with a 10x multiplier. While it may seem dated by today's standards, the Athlon 64 X2 4000+ was a notable offering at the time, particularly for budget-conscious users seeking multi-threaded performance. As of early 2026, the processor is well over 17 years old, placing it firmly in the category of legacy hardware. Its relevance today lies primarily in retro computing, low-cost systems, or educational purposes rather than modern performance demands.

The Athlon 64 X2 4000+ is designed for the Socket AM2 platform and uses a 90 nm manufacturing process, with a die area of 220 mm² and 154 million transistors. It features two cores and two threads, with no simultaneous multithreading support, and operates at a core voltage of up to 1.35 V. The processor includes 512 KB of L2 cache, split evenly between the two cores, and supports dual-channel memory. Despite its age, it maintains compatibility with modern systems through adapter solutions, though it lacks support for newer instruction sets like SSE4. The TDP of 89 W indicates moderate power consumption for its era, though it is significantly higher than modern low-power alternatives.

Integrated graphics are not present on the Athlon 64 X2 4000+ itself, but certain motherboards with compatible chipsets can provide this functionality. This makes the processor suitable for systems where a discrete GPU is not required. The processor supports a range of AMD technologies, including MMX, SSE, SSE2, SSE3, 3DNow!, and AMD-V, which enables efficient virtualization. However, it does not support ECC memory, limiting its use in enterprise environments.

In benchmark testing, the Athlon 64 X2 4000+ achieves an overall score of 3993, placing it at #1894 out of 2060 processors. Its single-core score is 3821 (#1871), while its multicore score stands at 4252 (#1898). While these scores are modest by modern standards, they reflect the processor's position in the lower tier of the performance spectrum. The multicore score is slightly higher than the single-core score, indicating that the dual-core design provides a measurable advantage in multi-threaded workloads. However, it trails behind many contemporary CPUs, including the Intel Celeron J3355 and Core 2 Duo T7200, which achieve marginally higher benchmarks.

When compared to the top performers in today’s market, the Athlon 64 X2 4000+ is clearly outclassed. Processors like the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K dominate the rankings, with scores exceeding 9000 and 8000, respectively. Even mid-tier CPUs such as the Ryzen 9 9950X3D and Core i9-14900KS are orders of magnitude faster. The Athlon 64 X2 4000+ is best suited for basic computing tasks, such as web browsing, office applications, or light multimedia use, particularly in systems where cost and compatibility are prioritized over performance. For modern users, it serves more as a historical artifact than a practical computing solution.
