New for Oct 2026: NVIDIA's RTX Spark laptop chip (same family as DGX Spark's GB10) with ~301 GB/s unified memory. Windows on Arm; how much of the unified memory Windows lets the GPU use isn't published for every config, so our 75% figure is an assumption. No public llama.cpp benchmark yet: speeds are estimates.
