Look at the specification of the first two computers (link in the last row of the table). How many screens can be simultaneously used with these laptops, regardless of the characteristics of the GPU?


What are the data transfer rates on the available connections of the two laptops?


 

We now compare the processors of the three computers. The following table summarizes the key points. An official and exhaustive comparison is available here.

  • Discuss the differences between the three processors. Can you guess what the different features listed in the table mean?
  • Look at the CPU limitations with memory. Are these limitations respected in the hardware configuration of the three computers? Can we still add memory to the three configurations?

 

We now look at the graphics processing unit (GPU). The following table describes the features of the GPUs in the three computers.

Compare the features of the three GPUs. Can you understand the meaning of each feature listed in the table?

 

Consider a typical laptop battery of 50Wh. These laptop screens consume 10W to 20W depending on size and brightness.

Considering that the three main power consuming components in a laptop are the CPU, the screen and the GPU, discuss autonomy and power consumption of the two laptops.
