Single channel vs dual channel RAM for iGPU gaming: Dual channel is a must, but don't expect 2x FPS

Dual channel roughly doubles memory bandwidth, giving a 30-50% FPS boost in Valorant at 1080p low — not 100%, but a jump from 60 to 90 FPS is huge. Some games show up to 60-70% gains. Single channel starves the iGPU, so buy a matching stick and upgrade immediately.
