Nvidia RTX Spark laptops get GB10 silicon with faster memory and NPU

Testing reveals that Nvidia's RTX Spark laptop chip shares the same underlying silicon as the DGX Spark's GB10, but features faster memory speeds, a higher CPU clock, an active NPU, and enabled USB4 PCIe tunneling. While the GB10 benefits from a Linux memory model that allows the GPU to access the entire memory pool and includes a ConnectX-7 network link, the laptop variant provides a more complete Windows driver stack and improved native Arm64 gaming support.
