RTX Spark Enables Lighter Laptops With 110W TDP, Surface Laptop Ultra Leads The Way
NVIDIA's RTX Spark for Windows on ARM promises higher efficiency, allowing lighter, quieter notebooks. The Surface Laptop Ultra uses about 110W TDP for the GPU, lower than desktop-class GPUs (up to 175W) and below some 140W ASUS configurations, potentially reducing the need for heavy cooling. Undervolting may be possible depending on software controls, though cooling performance on thinner designs remains a key question as this technology rolls out.
