Phenom II N660 Details

With a 15 W TDP and a 22 nm manufacturing process, the Phenom II N660 represents a low-power, dual-core processor designed for compact and energy-efficient systems. While its performance metrics may seem modest by today’s standards, it was positioned as a budget-friendly option for basic computing tasks when released. As of March 2026, the processor remains a legacy device, having been superseded by far more advanced architectures and multi-core designs. Its 2.0 GHz base clock and 2.3 GHz turbo frequency, combined with Hyper-Threading, deliver moderate responsiveness in single-threaded workloads, though it falls short in heavy multitasking or modern applications.

The Phenom II N660 operates on the Zen+ microarchitecture and is built for the FCBGA1168 socket, supporting DDR3L and LPDDR3 memory types at up to 1600 MHz. It features a 25.6 GB/s memory bandwidth and a maximum of 16 GB of RAM, with two memory channels and up to 12 PCIe lanes available via PCIe 2.0. The processor integrates an Intel HD Graphics 4400 GPU, which supports up to three displays and runs at a base frequency of 200 MHz, with a burst frequency of 1000 MHz. This integrated graphics solution enables basic multimedia playback and light gaming but lacks the power for modern 3D applications.

In benchmark testing, the Phenom II N660 achieves an Overall Score of 4303, ranking #1526 out of 2060 processors, with a Singlecore Score of 4258 and a Multicore Score of 4370. These results place it behind several Intel and AMD models from the same era, including the Pentium 4405U and A6-3670, but slightly ahead of the Pentium E5800 and Celeron G1820. Notably, its single-core performance is among the top 15% of its peer group, indicating strong efficiency for light applications, while its multicore score reflects the limitations of its dual-core design.

The processor supports a range of modern technologies, including AES encryption, AVX2, SSE4.1, and SSE4.2, as well as virtualization features like VT-x and VT-d. It also includes Intel vPro, TXT, and EPT for enterprise environments, alongside EIST for power management. Despite its age, the Phenom II N660 remains a viable option for low-power laptops, embedded systems, or secondary devices where energy efficiency and cost are prioritized over raw performance.

In summary, the Phenom II N660 is a niche processor suited for basic productivity and media consumption tasks. Its performance is constrained by its dual-core architecture and 22 nm process, making it unsuitable for demanding applications. However, its low power consumption and integrated graphics make it a practical choice for lightweight systems in 2026, particularly in environments where energy efficiency and affordability are key considerations.
