That being the case, you’d assume that you could build a PC by the end of 2020 that would be more powerful than the PS5 and Xbox Series X will be in five years without any kind of hardware updates. The situation isn’t quite that cut and dry, but it would be possible based on what we currently know.
The biggest problem with that comparison, though, is that it looks at things from a purely technical point of view. It doesn’t account for variations in individual components, required applications, overclocking, or a hundred other things that separate a custom-built PC from a gaming console.
Most importantly, it doesn’t account for the fact that when most studios develop a game, they typically don’t develop it to test the gamers with the most powerful hardware.
Just look at the biggest PC exclusives from the last several years. It’s a list that includes names like StarCraft II, World Of Warcraft, Total War: Shogun 2, and DOTA 2. Those are great games, but they’re not exactly technically demanding titles that require a top-of-the-line PC to properly run. At a time when the lines that separate PC and console gaming become thinner, you don’t see a lot of games like Crysis which were specifically designed to test the capabilities of the PC platform.
In fact, some of the most technically demanding PC games in recent years (such as Red Dead Redemption 2 and Metro Exodus) are multi-platform titles with PC ports that were carefully designed to offer high-end graphics options that the developers knew most gamers wouldn’t be able to run. Other popular benchmark games like Grand Theft Auto 5 typically require you to install several graphics mods before they can really be used to test the capabilities of a high-end gaming PC.
