Does RAM speed matter more for AMD in games like Cyberpunk 2077 and Starfield?

Yes, but not equally. In CPU-heavy games, AMD Ryzen systems see bigger gains from faster RAM than Intel systems do because AMD’s chiplet architecture scales with memory clock speed. A jump from DDR5-4800 to DDR5-6000 might give 10-15% more frames on a Ryzen 7800X3D in Starfield, but only 3-5% on a Core i7-14700K. If you’re budget-constrained, prioritize RAM speed on AMD; on Intel, spend the extra $30 on a better GPU instead.
