The spec I haven't seen listed on any of these RTX Spark laptops is the memory bandwidth. Seeing as it's listed as having up to 128GB LPDDR5X, I can guess that it's about the same as an AMD Gorgon Halo's 192GB around 273 GB/s which is where I lose interest. Even the M5 Pro at 307GB/s can't compare to discrete GPUs.

Only when we get to M5 Max 614 GB/s and Ultra 1.2TB/s does it get interesting for me.
