Athlon X4 845 Details

As of March 2026, the AMD Athlon X4 845 remains a niche offering in the desktop CPU landscape, representing a legacy design from the mid-2010s. Despite its age, the processor delivers a balanced performance profile, particularly for basic computing and light productivity tasks. Built on AMD's Carrizo architecture and manufactured on a 32 nm process by GlobalFoundries, the Athlon X4 845 operates at a base clock of 2.5 GHz with a turbo frequency of up to 3.3 GHz. It features four cores and four threads, operating under a 65 W TDP and using the LGA1155 socket, which places it in the same generation as early Intel Haswell processors. The CPU supports dual-channel DDR3 memory, with a maximum rated speed of 2133 MT/s and a memory bandwidth of 34.1 GB/s, making it suitable for systems with modest memory demands.

The Athlon X4 845 lacks integrated graphics, requiring a discrete GPU for visual output, which limits its appeal in all-in-one or budget builds. However, it includes a full suite of instruction set extensions, including AVX, AVX2, SSE4.1, SSE4.2, and AMD-V virtualization, enabling it to handle modern software and virtualization workloads effectively. It also supports hardware virtualization, which enhances performance in virtual machine environments. The processor is not equipped with Simultaneous Multithreading, meaning it does not support hyper-threading, which limits its ability to scale in multithreaded applications.

In benchmark testing, the Athlon X4 845 achieves an overall score of 4551, placing it at #1233 among 2060 processors. Its single-core score of 4583 ranks it at #1226, while its multicore score of 4502 places it at #1221. These results indicate that the processor performs comparably to entry-level and mid-tier CPUs from the same era, such as the Core i3-6100E and Pentium G6400. In the single-core performance tier, it trails behind more modern processors like the Core Ultra 9 285K and Ryzen 9 9950X3D, which dominate the top rankings. However, in multicore scenarios, it holds its own against older Xeon and Core i7 models, though it falls significantly behind contemporary high-end CPUs like the Ryzen Threadripper PRO 9995WX.

When compared to its immediate peers, the Athlon X4 845 sits between the Celeron G4930 and the A10-6790K, offering a slight edge in performance due to its higher base and turbo frequencies. Its closest competitors in the same score range include the Core i7-2715QE and the A10-6700, both of which are similarly targeted at budget and mainstream desktop users. The processor’s strongest performance category is single-core, where it achieves a score just below the Core M 5Y71 and Pentium G2030, indicating suitability for tasks like web browsing, office applications, and light multimedia editing.

In conclusion, the AMD Athlon X4 845 is best suited for users requiring a low-cost, energy-efficient CPU for basic desktop use. Its lack of integrated graphics and limited modern features, such as AVX-512 or PCIe 4.0 support, make it unsuitable for gaming, content creation, or high-performance computing. However, its low power consumption and compatibility with older motherboards make it a viable option for system upgrades in legacy platforms or as a secondary processor in multi-CPU environments. For users seeking more advanced capabilities, modern alternatives from AMD and Intel offer significantly better performance and future-proofing.
