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.
The storage of the Precision 7960 is RAID 5 : 4 x SSD 4To. What is RAID?
