According to its promoter, all the games in the Steam library should at least be playable in these conditions.
On July 15, Valve surprised everyone by announcing the upcoming availability of a portable console designed for games from the Steam library that it promotes. Called Steam Deck, the machine had not been leaked, Valve having managed to keep the mystery around what inevitably makes one think of a cross between a classic PC and a Nintendo Switch console on a base relatively close to the PlayStation 5 / Xbox Series X|S. Steam Deck is effectively a gaming machine with controls on either side of a 7-inch diagonal screen... like the Switch.
On the other hand, Steam Deck is therefore designed to run games from the Steam library, like any PC. Steam Deck also has a technical architecture that is close to the latest generation consoles signed Microsoft and Sony. The beast is much less powerful than the PlayStation 5 and other Xbox Series X|S, but it is based on an APU developed by AMD mixing 4 cores / 8 threads Zen 2 at 3.5 GHz for the CPU part while the graphics solution is equipped with 8 RDNA2 cores clocked at 1.6 GHz.
This is an interesting performance that has nothing to do with what the Switch can offer, but it still seems to be far behind that of a "gaming PC". It's not an impression, but Valve is counting on the relatively "limited" image definition of Steam Deck (1,280 x 800) to keep the animation smooth.IGN 's American journalists were among the first to (summarily) test the beast and they are reassuring: " To test its capabilities, I tested about ten different games, some in first person like Doom Eternal or Portal 2 or others in third person like Death Stranding and Star Wars: Jedi Fallen Order and others in isometric 3D like Stardew Valley or Hades. For the most part, these games ran flawlessly in their basic settings on the handheld's 720p display and the handheld stayed pretty cool throughout these sessions."
For its part, Valve has partially answered the questions of many gamers. In the interview above (at about 2:30), Pierre-Loup Griffais specifies that the goal is to run all the games in the Steam library at least 30 frames per second in this definition of 1280 x 800 or 1280 x 720 for those who do not accept the 16:10 format. Pierre-Loup Griffais says that, so far, his team has not been able to find a single game that does not meet these conditions ... even on the most recent / most greedy.
