RTX Spark laptops with 128GB unified memory: nobody has benchmarked ComfyUI yet
thisguy883 · reddit · 2026-10-29
The poster asks about the new RTX Spark laptops (128GB unified memory models): nearly all reviews come from gaming reviewers who complain they lag dedicated gaming GPUs — missing the point, since these machines were marketed for AI workflows.
They don't expect it to beat a 5090, but want real ComfyUI performance with large image/video generation models on 128GB of unified memory — and can't find a single such benchmark anywhere. Owners are asked to share numbers.
