As chips grow more powerful they produce more heat, and a device that gets too hot slows itself down to stay safe. To avoid this, laptop and phone makers have improved cooling using techniques like vapor chambers, thin sealed structures that spread heat away from the chip quickly. These methods have become more common in 2026.
Good cooling means a device can hold its top speed for longer instead of dropping off after a few minutes of hard work. The engineering challenge is fitting effective cooling into ever thinner bodies. Progress here is easy to overlook, but it is often what separates a device that stays fast under load from one that fades.
