Best explanation would seem to be a rebalancing to increase efficiency - the M3 Pro was basically the same performance as the M2 Pro but at much greater energy

Best explanation would seem to be a rebalancing to increase efficiency - the M3 Pro was basically the same performance as the M2 Pro but at much greater energy efficiency. Now the M4 Pro has increased the performance again (I assume at a similar power draw as the M3 Pro)
