Ryzen 7 8840U Details

The Ryzen 7 8840U, launched in December 2023, is a mobile processor from AMD that delivers strong performance within its power envelope. Built on the Zen 4 (Hawk Point) architecture using TSMC’s 4 nm process, it features 8 cores and 16 threads thanks to Simultaneous Multithreading (SMT), enabling efficient multitasking and parallel workloads. With a base clock of 3.3 GHz and a turbo frequency reaching up to 5.1 GHz, it offers impressive single-threaded responsiveness, making it suitable for demanding applications. The chip operates at a 28 W TDP, ensuring thermal efficiency in thin and light laptops, while its integrated Radeon 780M graphics provide capable visuals for everyday use and light gaming. It supports DDR5 memory at up to 5600 MT/s via a dual-channel interface and includes PCIe 4.0 with 20 lanes for fast storage and expansion options.

In benchmark testing, the Ryzen 7 8840U achieves a single-core score of 6328, placing it at #166 among 2060 processors, and a multicore score of 5878, ranking #264. These results highlight its strength in single-threaded performance, where it outperforms many desktop CPUs like the Core i9-11900K and Xeon E-2286G. Its overall score of 6148 ranks it #197, indicating balanced performance across various workloads. While it falls behind higher-tier mobile and desktop processors such as the Ryzen 7 8840HS and Core Ultra 5 134U, it competes closely with similar mid-range mobile chips. The processor’s performance is particularly notable given its 28 W TDP, showing effective efficiency in mobile computing.

The Ryzen 7 8840U supports a wide range of modern technologies, including AVX2, AVX-512, AES-NI, and AMD-V, enhancing performance in content creation, encryption, and virtualization tasks. It also includes a Neural Processing Unit (NPU) capable of up to 16 TOPS, which enables AI acceleration for machine learning applications. With a 15.259 MiB L3 cache and 16 MB of total cache, it ensures fast data access for complex operations. The chip is designed for Socket FP8, which is common in current-gen laptops, and features a locked multiplier to maintain stability. As of March 2026, the Ryzen 7 8840U remains a compelling choice for users seeking high performance in portable devices without sacrificing efficiency.
