Dual channel helps a lot, but don't expect 2x.

No, it won’t double your FPS, but the improvement is big enough that you should upgrade immediately.

Your 5700G’s integrated graphics are sharing system memory. Single channel bandwidth is a massive bottleneck for iGPUs — they’re essentially starving for data. Going to dual channel roughly doubles memory bandwidth, and in games like Valorant, you can expect around a 30-50% FPS boost at 1080p low. Not 100%, but a jump from 60 to maybe 90 FPS is huge for smooth gameplay.

The real kicker: Valorant is CPU-light, but memory bandwidth matters more than you’d think. Some games show even bigger gains (up to 60-70%) with dual channel. And 8GB total is pretty tight for gaming — Windows plus Valorant is already eating half of that. 16GB gives you breathing room.

Don’t overthink it. Buy a matching stick (same speed, same timings if possible) and install it. Your iGPU will finally get fed properly.

Your iGPU is waiting for you to stop bottlenecking it.
