I’ve been searching for a new laptop recently and came across several questions about Ryzen CPUs and RAM. I’ve tried looking up the details, but I’m seeing a lot of conflicting information that might not be current. First, regarding the Vega graphics cards: do they consume a portion of the laptop’s RAM? Is this amount fixed or can it change depending on the situation? I currently have an 8GB RAM setup and a dedicated graphics card. Would a Ryzen system with the same amount of RAM be considered less efficient because part of it is reserved for the graphics card?

Second, I’ve always thought mixing RAM sticks of different sizes could hurt performance. Yet many models today offer 12GB with a soldered 4GB and another 8GB stick. Some say this setup is bad, while others claim new Ryzen designs support dual-channel operation. Do they still work well in dual-channel mode? Is it using full dual-channel or just partial? I’m curious why such a variety of configurations exists and whether it really makes a difference compared to a simpler 4+4GB setup. Any advice would be greatly appreciated.

I usually avoid using laptops unless they have 16GB. (just a personal choice) The iGPU memory is set, but you can adjust its size. (more is preferable) Most computers require a specific memory type for upgrades. You should check the manual to find a QVL if you need changes.
