AI boom pushes RAM prices back to 20 years ago; DDR4 up nearly tenfold in two years

PC memory prices are rising sharply as surging demand for high-bandwidth memory used in AI data centres squeezes overall memory production capacity and lifts consumer DRAM prices. DDR4 prices rose from about $0.9 per GB in 2024 to $8.41 in July 2026, while DDR5 climbed from about $2.2 per GB in July 2025 to $11.4 in July 2026. The figures reflect consumer-market low prices rather than contract or average selling prices.
