Intel is set to release the Arrow Lake-S desktop processors, which will be the first to feature a neural processing unit (NPU) on a desktop PC. While this may be a significant milestone, the NPU’s AI performance falls short compared to other processors on the market. Rumored specs suggest that the NPU in Arrow Lake-S will offer only 13 trillion operations per second (TOPS) of AI performance, which is significantly lower than the 45 TOPS offered by Intel’s Lunar Lake CPUs and the 50 TOPS provided by AMD’s Ryzen AI 300 series. Despite this, Intel’s decision to include a lower-performing NPU in Arrow Lake-S may not be a critical issue for desktop users.
The inclusion of an NPU in desktop processors is primarily aimed at handling AI and machine learning workloads while minimizing battery impact, making it more suitable for ultralight workstation laptops. Since battery life is not a concern for desktop users, the need for a high-performance NPU is less critical. Additionally, desktop computers designed for AI workloads typically rely on discrete GPUs for better AI processing capabilities. Nvidia’s RTX 4090, for example, offers up to 1321 TOPS of AI performance, highlighting the superiority of GPUs in handling AI tasks.
Even if Intel were to equip Arrow Lake-S with a more powerful NPU, it is unlikely to match the performance of a dedicated GPU for AI tasks. The presence of an NPU in Arrow Lake-S may serve as a marketing gimmick to claim the title of the first consumer desktop NPU, despite its limited impact on actual AI workloads. The NPU’s lower performance may not hinder the overall functionality of the processor, considering that very few scenarios would require a high-performance NPU in a desktop environment.
While Arrow Lake-S may not excel in AI performance, it raises questions about certain features, such as the Recall feature, which has been delayed. This feature, previously exclusive to Copilot+ PCs, may eventually make its way to desktops if successful. Overall, Intel’s decision to incorporate a lower-performing NPU in Arrow Lake-S reflects the current market demand for AI technology in both laptops and desktop GPUs, highlighting the evolving landscape of AI processing capabilities in consumer devices.
