Steam Deck was built from the ground up for an optimal PC handheld gaming experience, and hardware engineer Yazan Aldehayyat shows how – and why- they made it the way they did. Even more importantly, he shows how those decisions allow for developers to bring all different kinds of games to Steam Deck as an optimal experience for players.
The Steam Deck has four Zen 2 cores capable of eight threads up to 3.5 GHz. The GPU is RDNA 2-based with 8 CUs running at 1.6 GHz. This processor was designed from the ground up to be optimized for the 4 to 15 watt power envelope. The level of performance per watt would not have been possible using any off-the-shelf processor today.
The Steam Deck is one of the first devices to utilize LP5. LP5 offers a lot of great power saving features.
The Steam Deck aims to provide consistence performance for extended periods of time, using only clocks that they believe can be sustained indefinitely. You should get the same performance whether you are docked, on the move, downloading games, or in slightly elevated ambient temperatures.
The Steam Deck does not have any artificial limits on how much power the APU can consume, so they recommend that developers utilize FPS limiters.
The 45 watt USB-C charging port on the Steam Deck can be used for many different peripherals up to 7.5 watts, including webcams or storage devices. If used for docking, the port can support up to two 4k displays at 60Hzs.
