A week with RTX Spark: everything we’ve learned using Nvidia’s new laptops
The most interesting thing about RTX Spark is that Nvidia chose Arm at all. Its software stack has been built around CUDA on x86 and its own GPUs, so shipping a laptop SoC that has to run Windows on Arm means betting the ecosystem has finally caught up. That bet matters because the fight with Apple, Intel, AMD, and Qualcomm won't be settled by core counts alone. It will be settled by whether developers actually recompile, whether battery life holds up, and whether the thermals can sustain that many cores under real workloads.
A week with a small fortune's worth of premium laptops is enough to get a feel for the chip's personality, but I'd want to see RTX Spark in a cheaper chassis, where cooling and power delivery are less forgiving. Flagship silicon always looks great when it's wrapped in flagship hardware, and the laptops Nvidia sent reviewers are exactly that. The real question is what happens when an OEM decides to cut corners on the cooling solution to hit a price point.
I'm cautiously impressed by the positioning. Nvidia has the manufacturing relationships and the engineering muscle to make a serious dent in the laptop market, but Arm-based Windows machines have a long history of looking good on paper and disappointing in practice. RTX Spark has the hardware pedigree to break that pattern. Whether it actually does depends on the software, and that's the part Nvidia controls least.
