Gearbox boss Randy Pitchford has a reputation for being outspoken, and this week he’s expressing some public doubts about the direction of the Xbox Series X. After Xbox chief Phil Spencer commented on the new console sidestepping traditional tech improvements “as Moore’s law slows,” Pitchford worries that this might be an excuse. “Is Moore’s law slowing down?” Pitchford tweets. “How many transistors in the Series X? What if Moore’s Law is like the 4-minute mile? Your ambitious message for the Xbox One X was inspiring, but for Series X, well, this feels more like an excuse.“ Moore’s law was originally a pretty simple message – computing power doubles every two years, depending on which version of the rule you’re talking about – and more specifically refers to the number of transistors you can fit on an integrated circuit. The limits of hardware manufacturing have made it increasingly difficult to quantify the current position of the rule, but manufacturers like TMSC continue to assert that Moore’s law “is not dead.”
