Steam Deck from Valve is a full-fledged PC, with the exception of a portable form factor. In early April, the company announced that their console now officially supports the Windows 11 operating system. It has yet to do some work, but new and updated drivers are added on a regular basis.

The ETA Prime Internet source decided to connect an external full-size graphics processor to the console for desktop PCs. Unfortunately, there is no ThunderBolt port in Steam Deck, which means that the only way to connect an external graphics processor is through a slot M.2. It also means that the only such slot that has this console will be used by the graphics processor, while Steam Deck must be loaded from the MicroSD storage.

Unfortunately, none of the tested NVIDIA GeForce video cards currently does not work with the console. However, the console is loaded with AMD Radeon maps, which should be expected, considering that it is based on the AMD platform.

In the 3DMark Fire Strike AMD Radeon RX 6900XT video card with a bottleneck due to APU Steam Deck Van Gogh (Zen2) and connections M.2 scored 26855 points in the graphics test. Without EGPU, the built-in RDNA2 graphics offers about 4856 points, which means that the deck with AMD RX 6900XT works 5.5 times faster. TIMESPY test is even more impressive: IGPU gains 1576 points, while AMD RX 6900XT is almost 10 times faster - 15579 points.

In the game tests, the EGPU console is capable of playing games in 4K resolution in games such as Witcher 3 (~ 108 FPS, ULTRA) or GTA 5 (~ 73 FPS, Very High). In Elden Ring or Cyberpunk 2077, it worked at a speed of 47-70 frames per second with 1080P HIGH settings. These games may be limited to connecting the CPU and the graphics processor M.2.

The packer was clearly not intended to work with an external graphics processor. In the end, this is a portable console with limited efficiency to expand the battery life. Although the deck is already a large console compared to other portable devices, alone AMD RX 6900 XT more than 3 times longer, so as not to mention the power supply or all the necessary cables. However, this is what the computer played about, playing with hardware and make things faster.
