Athlon II X3 455 Details

The AMD Athlon II X3 455, launched in December 2010, is a triple-core desktop processor built on the Rana microarchitecture. Designed for mainstream computing, it operates at a base clock of 2.7 GHz with a turbo frequency of 2.6 GHz and features a 16.5x multiplier. Despite its age, the processor remains notable for its integrated graphics support, which depends on the motherboard chipset. It uses the FCLGA1155 socket and has a TDP of 55 W, making it relatively efficient for its time. The Athlon II X3 455 supports dual-channel DDR3-1333 memory, enabling a maximum memory bandwidth of 21 GB/s, and it can address up to 32 GB of system memory. With a 45 nm process node and 300 million transistors, it offers modest performance by modern standards but was competitive in its era.

The processor includes 512 KB of L2 cache per core, totaling 1.5 MiB, and features a 0.122 MiB L1 cache. It lacks integrated graphics but can leverage a motherboard’s chipset graphics in certain configurations, with a maximum display output of three monitors. The integrated GPU, when present, runs at 650 MHz base frequency and supports technologies such as DirectX 10.1, Shader Model 4.0, and OpenGL 3.3. The Athlon II X3 455 supports a range of instruction sets, including SSE, SSE2, SSE3, SSE4.1, SSE4.2, AVX2, AES, and AMD-V, which enhance multimedia, encryption, and virtualization capabilities. It also supports ECC memory and includes features like EIST and TXT for power management and security.

In benchmark testing, the Athlon II X3 455 achieves an Overall Score of 4372, ranking #1442 out of 2060 processors, with a Singlecore Score of 4335 (#1458) and a Multicore Score of 4428 (#1389). These results place it below modern high-performance CPUs but show it holds its own against older mainstream and budget processors. It outperforms several dual-core and quad-core CPUs from the early 2010s, such as the Core i3-5157U and the Phenom II X4 B95, while lagging behind more recent models like the Xeon E5430 and the Core i5-540M. Its multicore performance is slightly stronger than its single-core score, indicating better scalability across multiple threads.

As of March 2026, the Athlon II X3 455 is a legacy processor, no longer relevant for demanding applications or modern software. However, it remains suitable for basic office tasks, light multimedia use, and retro computing setups. Its low power consumption and compatibility with older motherboards make it a cost-effective option for upgrading older systems or building a low-power media center. While it cannot compete with today’s top-tier CPUs, its long-standing presence in the desktop market underscores its role in the evolution of affordable multi-core processors.
