NVIDIA Highlights Up to 128 GB of LPDDR5X in RTX Spark Systems

At Computex 2026, NVIDIA outlined RTX Spark systems built around the N1X platform, combining a Grace based Arm CPU with a Blackwell RTX GPU over NVLink C2C. The company said configurations can reach 128 GB of LPDDR5X unified memory across laptop, mini PC, and DGX Spark style designs. The memory significance is strategic rather than immediate. Larger LPDDR5X pools in premium client and edge AI devices could support demand for high capacity mobile memory over time, but the source does not include suppliers, volumes, pricing, or launch timing that would justify a direct market call.
