Summary
NVIDIA’s first RTX Spark Windows driver—version 616.00 Developer Preview—points to two SoC variants labeled RTX Spark N1X, with Blackwell GPUs carrying 6,144 and 5,120 CUDA cores.
The driver’s .inf file suggests the 6,144-core model pairs with a 20-core MediaTek CPU and 48 streaming multiprocessors, while the lower tier likely uses an 18-core CPU and 40 SMs.
Both versions are expected to support up to 128GB of LPDDR5X memory, giving the lower-end configuration the same maximum RAM ceiling as the flagship model.
CUDA counts alone do not define performance: 6,144 cores matches desktop RTX 5070 and laptop RTX 3080 specs on paper, while 5,120 aligns with a laptop RTX 3070.
