As you may already know, Microsoft doesn't report Xbox sales figures. The company stopped keeping us up to date all the way back in 2015, after it became clear that the Xbox One's numbers would not paint a pretty picture when compared to the runaway success of the PlayStation 4. Since then, we've had to rely on third-party data to fill in the blanks while Sony continues to provide PS4 sales statistics.
This time, it's computer technology company AMD that's spilled the beans. During a recent financial briefing, AMD stated that total PS4 and Xbox One sales amount to 150 million units. Just a few weeks ago, Sony announced that the PS4 was sitting at around 109 million units, and so that means the Xbox One is currently trailing by some distance at around 41 million units. In other words, Sony's sold 68 million or so more current-gen consoles than Microsoft.
Interestingly, this is a gap that's widened since we could last compare data like this. In 2018, EA's reports put the Xbox One around 50 million units behind PS4, which, at the time, was approaching 80 million. Under two years later, and Sony has put an additional 18 million units between its console and the Xbox One. These are PS2-levels of market domination.
Of course, Sony will be keen to carry this momentum into the next generation, with the PlayStation 5 still set to launch in late 2020.
