Is DDR5 worth the upgrade over DDR4?

DDR5 and DDR4 prices are converging in 2026, but DDR5 gaming performance gains remain under 5% in most titles. DDR5 is worth it for new builds on platforms that only support DDR5 (like Intel 13th/14th gen and AMD AM5). For existing DDR4 systems, upgrading to DDR5 requires a new motherboard and CPU — rarely cost-effective just for a memory upgrade.
