AMD Ryzen 8040 Series: Technical Details and Software Platform

Published by

AMD has released the Ryzen 8040 series of laptop processors, an update to the existing Ryzen 7040 series. These processors are designed with enhanced compatibility for a newly introduced software platform, which aims to streamline the development of AI applications by leveraging the integrated neural processing unit (npu). The Ryzen 8040 series includes four U-series processors, recognized for their energy efficiency, with a thermal design power (TDP) of 28W that can be adjusted from 15 to 30W.  Additionally, the series features five HS models with higher TDPs, typically around 45W and adjustable between 35 and 54W. These processors are built on the Phoenix die architecture, similar to the Ryzen 7040 series, incorporating Zen 4 cores for CPU tasks, RDNA 3 architecture for integrated graphics, and a first-generation XDNA architecture for GPU computing.


The naming convention for the Ryzen 8040 series, such as Ryzen 9 8945HS, reflects the year of release (2024) and the core architecture (Zen 4). The clock speeds in the 8040 series do not show a substantial increase over the previous generation, with the top model maintaining a maximum boost speed of 5.2GHz, comparable to its predecessor in the 7040 series. AMD has highlighted firmware and driver optimizations in the 8040 series, suggesting these improvements will contribute to a notable performance upgrade over the 7040 series, particularly in AI performance, which is anticipated to improve by up to 60%.

In conjunction with the processor launch, AMD has released the Ryzen AI Software Platform. This platform is backward compatible with the Ryzen 7040 series and supports AI model execution using popular frameworks like PyTorch, TensorFlow, and ONNX on the Ryzen AI npu. To promote AI development, AMD is organizing a competition with a prize pool of $160,000, encouraging innovation in areas such as robotics, personal computing, and generative AI.


In the absence of direct generation-on-generation comparisons for gaming and productivity benchmarks, AMD has recently contrasted the performance of its Ryzen 8000 series, presumably the Ryzen 9 8945HS (incorrectly referenced as 8940H), equipped with Radeon 780M integrated graphics, against Intel’s Core i9-13900H with Xe integrated graphics.

AMD's evaluation included nine gaming benchmarks, featuring titles such as Borderlands 3, Far Cry 6, and Hitman 3, to create a unified measure of gaming performance. According to AMD, its processor demonstrates a performance increase of 1.8 times compared to the Core i9-13900H in 1080p gaming under low fidelity settings. Furthermore, AMD reports a 1.1 times performance improvement in multi-threaded applications, as evidenced by results from Cinebench R23 and Geekbench 6 benchmarks.

In addition to gaming and general productivity, AMD has also assessed performance in content creation tasks. It claims its processor architecture delivers up to 1.4 times faster performance than the Core i9-13900H in various content creation workloads, including usage of software such as Blender, POV-Ray, and PCMark 10. This comparison highlights the capabilities of AMD's latest processor series in a range of applications, from gaming to content creation.
