16GB dual-channel is mandatory for the 5600G iGPU

Yes, 16GB dual-channel makes a huge difference for the 5600G’s integrated graphics—think 30-50% better frame rates in many games.

The Vega 7 iGPU in that chip is memory bandwidth hungry. Single-channel RAM starves it. You’re leaving 40% or more performance on the table. In games like Fortnite or GTA V, going from 8GB single-channel to 16GB dual-channel can turn a stuttery mess into a genuinely playable experience at 1080p low settings. The gap is that wide.

Also, 8GB is just not enough for a modern gaming PC anyway. Windows alone eats 3-4GB. Add a game, a browser tab, Discord? You’re swapping to disk instantly. That kills performance even before you factor in the iGPU stealing bandwidth. 16GB dual-channel is the bare minimum for usable gaming on this APU.

If you’re building a budget machine with the 5600G, spend the extra $20-30 on a 2x8
