redletterdave writes: The PlayStation 4 has a few notable advantages over the Xbox One: The PS4's graphics chip is roughly 50% more powerful than the Xbox One, and the difference in RAM gives a huge bandwidth advantage for Sony's console as well. Microsoft tried to close the performance gap in the Xbox One last year, unlocking more graphics bandwidth for developers, as well as the 7th core in its 8-core processor. But Microsoft was forced to make trade-offs in order for that to happen. And despite those improvements, the frame rate and resolution of many Xbox One games doesn't match the quality on the PlayStation 4 on paper. And that was before Sony unlocked the 7th core in its 8-core processor for developers, which the company quietly rolled out in a new software development kit (SDK) update last week.
