DDR5 4800 MHz RAM Sourcing Guide 2026

The phrase "DDR4 4800" is currently a point of significant market confusion, as 4800 MT/s is actually the entry-level baseline for DDR5 technology. While enthusiast-grade DDR4 can reach high speeds, standard DDR4 typically tops out at 3200–3600 MHz.

Key Market Insights for 2026

* Terminology Alert: In current sourcing contexts, "4800 MHz" almost exclusively refers to DDR5. Baseline DDR5-4800 modules now outpace even high-end DDR4 in bandwidth (4.8 Gbps vs. 3.2 Gbps) and are the new industry standard. Atpinc Davescomputers

* The Price Inversion: A "scissors gap" has emerged where legacy DDR4 is becoming more expensive than modern DDR5. DDR4 prices spiked up to 10% in a single week in early 2026, with some retail kits nearly tripling in cost over two months due to extreme supply tightness. Unibetter-Ic Tomshardware

* AI-Driven Supply Shift: Manufacturers (Samsung, SK Hynix, Micron) have diverted wafer capacity to High Bandwidth Memory (HBM) to meet AI demand. This has "cannibalized" DDR4 production, leading to a structural shortage and Micron's planned "hard exit" from DDR4 in Q1 2026. Unibetter-Ic Innoaiot

* Sourcing Recommendation: For 2026 deployments, the consensus is an immediate migration to DDR5. The price-per-GB for DDR5 is now often lower than for scarce, legacy DDR4 modules. Tomshardware Pcserverandparts
