Not only is this memory optimized for mobile hardware, its four channels provide a huge amount of bandwidth to the APU. The hardware includes 16GB of four-channel LPDDR5 RAM, the latest flavor of Low Power Double Data Rate memory. Though its GPU specs may look underwhelming on paper, the Steam Deck’s overall performance will be greatly enhanced by its speedy memory. RAM: 16GB LPDDR5 (5500 MT/s quad 32-bit channels).

Here’s a quick look at the base specifications shared by all Steam Deck models: Understanding Steam Deck specifications and performance To better understand performance, we need to understand what makes the Steam Deck APU different from the usual sort of desktop PC hardware. These are chips that contain both CPU and GPU, meaning the Steam Deck’s GPU is part of a larger chip instead of being a discrete graphics processing unit.

That’s because Valve based the Steam Deck around a modern AMD APU, or accelerated processing unit. Unfortunately, that sort of comparison doesn’t tell the full story.
