Difference between mobile and desktop processors

By Prof. Fazal Rehman Shamil

Both PC and mobile phones are made for different reasons. Mobile phones are commonly used for communication and PC are used for office works and other official tasks.  Now a day mobiles can also be called minicomputers. As mobiles are easy to use and do the official tasks with the help of different applications, so that’s why they are getting more and more popular in the general public. But when they come against a fully-fledged PC, the mobile phone stays way far behind in speed, processing, and other basic stuff.

Mobiles and PC have quite a similar style of processing. In fact, processors come in two classes; mobile and desktop. Mobile processors are particularly small in size as compare to desktop processors. Devices such as laptops, smartphones, and IoT devices have mobile processors. Mobile processors are designed to be efficient as compared to have more performance. These processors are highly efficient but not have that good performance as compared to desktop processors.

As we all know that processors generate a lot of heat as we see that in computers. But when it comes to mobile phones, when we use the same processor, it might melt the components of mobile devices. One of the major drawbacks of mobile processors is when they get really heated they limited their speed, which equates to slower performance.

The other big difference is regarding performance. If you take a computer and compare it to a mobile device with the same speed as the 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.

Some say that both desktop and mobile share the same processor by name such as i7, some do believe that they are equal in almost everything but the reality is no, they are not. Even though both desktop and mobile processors can share the same i7 name, that doesn’t mean they’re totally equal. For example, a desktop Intel Core i7-6700 runs 4 cores at 3.4/4.0 GHz with 8MB cache for a Pass mark score of 9,973. Its mobile counterpart, the Intel Core i7-6700HQ, comes in at 2.6/3.5GHz with 6MB of cache for a Pass mark score of 8,001, or almost 20% less.

The major differences come when we compare mobile processors with desktop processors, the desktop version will defiantly have higher speed processing and better cache as compared to the mobile processor, Mobile features a reduced speed. Compare the two models below: the mobile core i7 processor has the same clock rate as the Desktop i5 core. The Desktop has twice more cores than the mobile core i7 and a small improvement on the GPU Clock rated speed. It means that Desktop CPUs are more powerful. They can handle more devices: that’s why they are designed for a full-size PC.

As it is very well known that processor and other mobile technology is advancing with an extreme speed and it is not possible in the near future that we might see mobile devices more powerful and have more performance than a desktop computer.

Type Processor Model Cores Clock Rate GPU GPU Clock TDP
Desktop Intel Core i5 7500T 4 2.7 GHz HD 620 1100 MHz 35W
Mobile Intel Core i7 7500U 2 2.7 GHz HD 620 1050 MHz 15W
