On Monday, Cook teased a product drop happening this week. He didn't specify the day or time, but the "air" hint all but confirms strong rumors that it will be the M4 MacBook Air. This was predicted by Bloomberg 's Mark Gurman who expected a March launch. Given that today is the first business day in March, that prediction is right on track.

The M3 chip in the current 13-inch MacBook Air has 8 CPU cores and 8 GPU cores, and the M4 chip in the baseline 14-inch MacBook Pro has 10 CPU cores and 10 GPU cores. The M3 and M4 chips feature a 16-core neural engine that supports Apple Intelligence features, but Apple says the M4 is twice as fast as the M3 with AI workloads.
