Valve’s Steam Deck is a seriously impressive piece of it, thanks in no small part to the power-efficient, highly capable AMD Van Gogh APU that runs the show. As we’ve already seen, this portable PC can match the PlayStation 4 experience at lower resolutions, while its support for ray tracing in combination with its built-in SSD stands it in good stead for future games. However, with demanding software on the horizon and last-gen systems finally starting to fall by the wayside, Microsoft’s Xbox Series S is establishing itself as the baseline for modern gaming. So here’s the question: can we pushHowever, the performance targets are all identical to the original code. e for sure, but if we can get there, perhaps we’ll have some idea of the handheld’s longer-term prospects when dealing with ever more demanding games.
Looking at the specs, the two systems don’t look quite as far apart as you may think. Both machines are based around the same AMD technologies – Zen 2 CPUs paired with RDNA 2 GPUs. The Steam Deck is substantially pared-back relative to its stronger console cousin, but critically it is targeting a much lower output resolution. The Series S is typically aiming for pixel counts in the 1080p to 1440p range, while the Steam Deck is limited to just 1280×800 on its internal display, or 720p with 40-pixel black bars top and bottom.
So, the fact that the Steam Deck is theoretically a little less than half as powerful in GPU compute and RAM bandwidth isn’t a huge issue here. A seven-inch screen with essentially a 720p resolution is a forgiving canvas for game content relative to a large-format 4K television and in many cases, cutting resolution alone may be enough to give us the slack we need to equal the junior Xbox. One levelling factor to consider, however, concerns power consumption. Steam Deck’s APU has a 15W power limit, with full system power hitting a maximum of around 26W. Meanwhile, it’s impossible to gauge the Series S SoC’s power draw, but the entire system maxes out at around 82W of juice measured at the wall with a watt meter. There is, however, another factor in the Deck’s favour – it actually has more memory than the Series S.
