Dual-channel RAM is essential for the 5600G's iGPU.

Yes, absolutely. Going from 8GB single-channel to 16GB dual-channel is a massive performance jump for the integrated graphics on a Ryzen 5 5600G.

The integrated GPU is starving for memory bandwidth. Single-channel RAM is like a single-lane road – it bottlenecks the graphics chip hard. Dual-channel doubles that bandwidth, which directly translates to higher frame rates and smoother gameplay. You might see 50-100% gains in iGPU performance just from switching to dual-channel.

The capacity jump from 8GB to 16GB also matters. An APU shares system RAM with the CPU, and Windows alone eats 2-3GB. With 8GB total, you’ll run out of memory quickly, forcing the system to swap to your SSD, which kills performance. 16GB gives the iGPU room to breathe.

So yes, it’s not just a small improvement – it’s the difference between a playable machine and a stuttery mess. Spend the extra ~$30.

Don’t build an APU on single-channel unless you hate yourself
