CPU加速AI普及，GPU首次加AI，Arm为何把NPU留给伙伴？

TL;DR - Arm launched CSS for Mobile 2, pairing C2 CPUs with stronger SME2-based AI acceleration and the first Mali GPU with an integrated neural accelerator. The platform targets faster, more accessible on-device AI while leaving differentiated NPU designs to chip partners.

• C2 Ultra improves single-thread and web performance by 15%, while SME2-enhanced C2 CPU clusters deliver up to 1.7× performance on selected AI models.
• Mali G2-Ultra NX uses neural super-sampling, denoising, and frame generation to achieve up to 4× frame rate and energy efficiency while reducing DRAM traffic by as much as 70%.
• Arm positions CPUs for low-latency orchestration and lightweight models, GPUs for graphics and general AI compute, and partner-designed NPUs for sustained, compute-intensive workloads.
• KleidiAI kernels, SDKs, open neural-graphics models, and engine integrations abstract hardware details so developers can adopt the new capabilities without rewriting applications.
