Not sure of this is correct, but my observation is that the Memory usage of Windows 7 or Windows 8 is somewhat directly proportional to the size of the computer's total Memory/RAM.

Example:
Asus Laptop with 16GB of RAM running Windows 8.1 with 9 startup programs and only one active open program,Google Chrome with 1 tab, memory usage is 3.4 GB to 3.6 GB.

My home desktop has Windows 7 and has only 4GB of RAM, it consumes only around 2.0 GB to 2.2 GB with 1 tab in Google Chrome.

I also obvserved a similar behavior to different computers with different configurations.

What's your thought about it?

4GB for Windows 7 is on the "tight" side. Consequently, the memory management logic in the OS conserves resources. Having NO free memory is a bad (slow) situation for the OS. The memory manager is always looking to have free memory for new tasks. It will page out least recently used things from memory to the swap file if necessary. With less physical RAM, the OS will also use less resources for I/O buffering.
