When processors run they generate heat. Lots of heat. Because mobile devices are considerably smaller than computers, the heat generated by a running mobile processor is often amplified and can seriously harm components, or even melt them. Therefore, the developers and designers of the devices limit, or throttle, the speed at which a mobile processor can run. This means that if a processor is getting hot, it will limit its speed, which equates to slower performance. Because of this throttling, the processor on many phones will actually run slower than the advertised speed. In fact, the advertised speed of mobile processors is normally the maximum. Compare this to most computer processors, where the advertised speed is usually the average running speed, and you begin to see why computers are more powerful. The second big difference is connected with performance. If you take a computer and compare it to a mobile device with the same speed of processor, the computer will usually be able to do more. This is because the processor is limited in what it can do by the other hardware components, like the RAM, Graphics Processing Unit, etc. Computers have more space, so they can fit more advanced components, and are consequently able to do more. That being said, processor and other mobile technology is advancing at a blistering pace and it is highly likely that mobile hardware will continue to increase in overall power, and eventually be able to compete more effectively with larger computers.

Laptop processors rely more on throttling where speed is ramped up when extensive applications requires it. In return when the CPU is at it's highest performance setting it will use more battery power and will decrease battery life. Desktop processors generates more heat and requires a better cooling system such as bigger fans and heatsinks. Not only the CPU generates heat but the RAM, video chip and hard drives including SSD's produce heat. If you get a warning that the laptop's temperature is high either decrease it's speed such as setting it at battery saving mode or get a laptop cooler so it can dissipate the internal temperatures and make sure the laptop's vents are not obstructed. This is were you see in the news their laptop catching fire in bed.

Smaller form factors mean combating thermals(heat) in different ways. The most effective way to combat heat in these small devices is to reduce the amount of power the CPU needs to operate. Mobile CPUs do this by offering a wide range of operating frequencies. In this case, the base frequency is 1.9Ghz. That's pretty slow by today's standards but maximum frequency under high load is 4.2Ghz! On the low end when the CPU isn't working a whole lot, it's using only 15W of power and ramps up to 25W. For comparison, the closest desktop model CPU uses 65W. This is a relevant comparison because the power used by the CPU directly affects how much heat is created during operation. The other notable difference is cache on the CPU. This is like super fast memory that is as close to the processor as possible to ensure the fastest possible computations. Cache also takes power to operate, so the mobile model CPUs have less cache but still a capable amount (8GB vs 12GB for desktop model) to facilitate the expected performance for mobile model CPUs. The short of it is, the mobile models are used in more compact sizes due to heat. Laptops can absolutely be purchased with desktop model CPUs, but you will find them in larger sizes to accommodate the components that are needed to sufficiently cool it such as larger heatsinks and more or larger fans to remove the heat from the chassis. Hope this helps!
