What a GPU actually does
You already have a GPU in your Mac. Start by finding it. You do not need to buy anything or install NVIDIA software.
The course follows the whole system
- Your computer
Identify the GPU and its working memory
- A server and rack
Connect GPUs, network, power, and cooling
- A working service
Run jobs, observe failures, and recover
Find your GPU
Open System Information → Graphics/Displays. Note the GPU or chipset name.
Then open Activity Monitor → Window → GPU History. Compare the graph while idle and while using a graphics-heavy app you already have. If that view is unavailable, just record the hardware name.
This is observation, not a performance test. Video playback may use separate media hardware, so a quiet graph is not necessarily a problem.
What you are looking at
The CPU runs the operating system and coordinates work. The GPU helps with suitable calculations. Memory holds the numbers they need; storage keeps files.
This course follows those connections from one computer to an entire data center.
Try it yourself
Write down your GPU name, the activity you tried, and what changed.
Check your answer
There is no required percentage. A useful result is a clear observation, including “no visible change.” Do not install NVIDIA drivers on an Apple GPU; later NVIDIA exercises need different hardware.
