Athlon II X2 240 Details

As of March 2026, the AMD Athlon II X2 240 remains a relic of the late 2000s, reflecting a time when dual-core processors were the standard for mainstream desktops. Launched in July 2009, this processor is now over 16 years old, placing it firmly in the category of legacy hardware. Despite its age, the Athlon II X2 240 still offers a glimpse into the evolution of consumer computing, particularly in the realm of integrated graphics and multi-core performance. Designed by AMD and based on the Regor microarchitecture, the processor was built for the desktop market and features a 45 nm manufacturing process. It operates at a base clock of 2.0 GHz with a turbo frequency of 2.3 GHz, running on a 1333 MHz bus and utilizing a 14x multiplier. The chip contains 410 million transistors and has a die area of 117 mm², packaged in a µPGA format and mounted on the LGA771 socket.

The Athlon II X2 240 is a quad-core processor with four physical cores and four threads, lacking Simultaneous Multithreading (SMT) and a locked clock multiplier. It features 2 MB of L2 cache and supports dual-channel DDR3L and LPDDR3 memory up to 16 GB, with a maximum memory bandwidth of 25.6 GB/s. The processor has a TDP of 80 W, which was typical for its era, and supports PCIe 2.0 with up to 10 lanes. Notably, it does not include integrated graphics, though certain motherboards with compatible chipsets can enable this functionality. The processor supports a wide range of instruction sets, including SSE, SSE2, SSE3, SSE4.1, SSE4.2, AVX2, AES, x86-64, AMD-V, and 3DNow!, providing a robust foundation for older software and virtualization tasks.

In terms of performance, the Athlon II X2 240 scores 4144 in the overall Passmark benchmark, ranking it #1751 out of 2060 processors. It achieves a single-core score of 4166, placing it #1613, and a multicore score of 4111, ranking #2045. These results highlight its position as a mid-tier performer in its time, though it now trails behind nearly all modern CPUs. When compared to contemporary processors, it is outperformed by the top-tier Ryzen Threadripper and Core Ultra series, which exceed 8000 in overall scores. However, within its own generation, the Athlon II X2 240 competes with similar models like the Core 2 Duo and Celeron variants, which have marginally higher scores but share similar architectural limitations.

The processor's strongest attribute is its single-core performance, which ranks higher than its multicore score, indicating that it performs relatively well in applications that rely on single-threaded execution. However, its multicore performance is significantly weaker, making it less suitable for modern multi-threaded workloads such as video editing, 3D rendering, or gaming. The Athlon II X2 240 is best suited for basic office tasks, light multimedia use, or as a replacement in older systems where cost and power efficiency are priorities. Its integration with older chipsets and lack of modern features like DDR4 support or PCIe 4.0 further limit its relevance in today’s computing landscape.

In conclusion, the AMD Athlon II X2 240 serves as a historical benchmark for the transition from single-core to multi-core processing in consumer desktops. While it once offered capable performance for its time, it now stands as a testament to technological progress, with modern processors delivering vastly superior performance and efficiency. For users seeking a budget-friendly upgrade or a retro build, the Athlon II X2 240 may still be viable, but for anyone looking to leverage current software and hardware capabilities, it is no longer a practical choice.
