Microsoft unveiled the Surface Laptop Ultra, a MacBook Pro competitor powered by the Nvidia RTX Spark. What if you could have that but minus the laptop? Meet the Surface RTX Spark Dev Box.The pitch is short but sweet: 1 petaflop of compute, 128GB of RAM, can run 120 billion parameter models locally. To add a bit more detail, that is 1 petaflop of FP4 with sparse matrices and the RAM is unified so it is shared between the CPU and the GPU.Speaking of which, the RTX Spark combines a 20 core Grace CPU (10x Cortex-X925 + 10x Cortex-A725) and a Blackwell GPU, which is the architecture...
