Comment on Sony announces the PS5 Pro with a larger GPU, advanced ray tracing, and AI upscaling

The game is rendered at a lower resolution, this saves a lot of resources. This isn’t a linear thing, lowering the resolution reduces the performance needed by a lot more than you would think. Not just in processing power but also bandwidth and memory requirements. Then dedicated AI cores or even special AI scaler chips get used to upscale the image back to the requested resolution. This is a fixed cost and can be done with little power since the components are designed to do this task.

My TV for example has an AI scaler chip which is pretty nice (especially after tuning) for showing old content on a large high res screen. For games applying AI up scaling to old textures also does wonders.

Now even though this gets the AI label slapped on, this is nothing like the LMMs such as chat GPT. These are expert systems trained and designed to do exactly one thing. This is the good kind of AI that’s actually useful instead of the BS AI like LLMs. Now these systems have their limitations, but for games the trade off between details and framerate can be worth it. Especially if our bad eyes and mediocre screens wouldn’t really show the difference anyways.
