Arm正式推出Mali G2-Ultra NX GPU，这是该公司首款将神经加速器直接集成到图形管道中的AI原生移动GPU 1。新芯片通过神经超采样（NSS）、神经帧率提升（NFRU）和神经超采样去噪（NSSD）等技术，在移动设备的功耗约束下实现桌面级视觉保真度，支持最高120FPS的游戏帧率 1。
Mali G2-Ultra NX相比上代产品实现了显著性能升级 1。基准性能最高提升24%，游戏性能提升14% 1。该芯片搭载第三代硬件光线追踪技术，可将DRAM流量降低13%，结合Opacity Micromaps技术可实现帧率提升30%、光线追踪工作负载降低70% 1。新执行引擎为每个warp提供高达2倍的寄存器数量 1。Neural Dawn演示数据显示，相比原生渲染该方案性能效率提升4倍，外部内存流量降低70% 1。
Mali GPU系列已积累超过140亿出货量 1。Arm已与腾讯游戏、Unity China以及《风起苍岭》等合作伙伴开展G2-Ultra NX的集成和开发工作 1。
Arm has introduced the Mali G2-Ultra NX GPU, marking the first AI-native graphics processor in its Mali lineup 1. The new chip integrates a neural accelerator directly into the graphics pipeline, enabling desktop-class visual fidelity on mobile devices within strict power constraints 1.
The Mali G2-Ultra NX delivers performance improvements of up to 24% in baseline benchmarks and 14% in gaming performance compared to its predecessor 1. Advanced AI-driven rendering techniques—including neural supersampling, neural frame rate upscaling, and neural supersampling denoising—allow the GPU to sustain gameplay at up to 120 FPS 1. A Neural Dawn demonstration showed a fourfold increase in performance efficiency over native rendering, with external memory traffic reduced by 70% 1.
The GPU's third-generation hardware ray tracing reduces DRAM traffic by 13%, while Opacity Micromaps technology achieves 30% higher frame rates and reduces ray tracing workload by 70% 1. An enhanced execution engine provides warp threads with up to twice the register capacity of previous generations 1. Arm has collaborated with Tencent Games, Unity China, and developers of titles such as "Winds of Blue" to optimize and integrate support for the new architecture 1.
