Anyone who takes Apple 38 TOPS claim seriously is misled, just like that time Apple compared its iGPU with 3070 Laptop without specifying. Most GPU do couple times over 38, Apple iGPU likely included. Even Intel CPU does more, that's a low bar.
NPU is a "background AI" device. It performs better than CPU and worse than GPU for low end tasks, without having to wake up messy GPU. It's not supposed to be fast at all.
Comparing SoCs by advertized TOPS figures is like comparing cars with reversing speeds. That sometimes matter, rarely the most relevant parameter.
- ForOldHack 2y agoJust how do you benchmark an AI? Do you ask it? There is a few pans of fundge factor. My car goes faster in reverse, something that I only need for movies like "the in-laws." ( Peter Falk and Alan Arkin)
- 1123581321 2y agoI am not seeing the misleading part. A neural network on processor/package is supposed to be good at preserving battery by doing all the low power, low precision tasks. More TOPS = more consistent battery life with heavier usage over the day, is how I'd explain it to an everyday user.
- numpad0 2y agoSome people think 38 TOPS claimed was itself some sort of groundbreaking achievement, despite it being just a lesser substitute to iGPU, closer to a biggest shipped E-core so far or fastest on-chip video encoder back then. That's the misleading part.
- wtallis 2y agoSaying that the NPU is a lesser substitute to the GPU is only accurate if you believe raw performance is the only important metric. Which means you're still missing the entire point of NPUs.
