RAM Price Index
The daily price per gigabyte of DDR4 and DDR5 memory, computed from the live retailer prices RamRadar collects across eBay, Newegg, and B&H Photo. Desktop (DIMM) and laptop (SODIMM) memory are tracked separately. Latest data: August 28, 2026.

What the data shows
As of August 28, 2026, desktop DDR5 memory averages $16.26 per gigabyte across the 196 kits RamRadar tracks, while desktop DDR4 averages $7.90 per gigabyte across 97 kits. The median kit (a better read on what a typical buyer actually pays, since premium and odd-capacity kits pull the mean upward) sits at $14.68/GB for DDR5 and $7.03/GB for DDR4.
Over the past 30 days DDR5 has risen 8.0%, from $15.05/GB on July 29, 2026 to $16.26/GB. DDR4 has climbed 6.1% over the same period, moving from $7.44/GB to $7.90/GB.
The sharpest seven-day swing in the DDR5 series came between November 24, 2025 and December 1, 2025, when the average moved from $7.59 to $10.69 per gigabyte, a 40.8% jump in a single week. For DDR4, the biggest weekly move ran from May 22, 2026 to May 29, 2026: $8.60 to $6.76/GB, a 21.4% decline.
The longest sustained DDR5 run in the dataset is a 6-day climb from November 24, 2025 to November 30, 2025, over which the average moved +42.2% ($7.59 to $10.80/GB). DDR4's longest streak is a 6-day descent from June 11, 2026 to June 17, 2026, worth -5.1% ($7.54 to $7.16/GB). Streaks matter because RAM pricing tends to trend rather than oscillate: several consecutive daily moves in one direction have historically been a stronger buy or wait signal than any single-day change.
DDR4 currently averages $8.36/GB less than DDR5 (51.4% below it). Across the last 30 days with data for both types, DDR4 averaged above DDR5 on 0 of them.
On the laptop side, DDR5 SODIMMs average $13.44/GB (17.4% below their desktop counterparts), while DDR4 SODIMMs average $6.75/GB across 77 tracked kits.
The index currently spans 312 days of data, from October 21, 2025 to August 28, 2026. Each daily point is aggregated from the cheapest prices RamRadar collects across eBay, Newegg, and B&H Photo, weighted by whatever each of those carries rather than evenly, and normalized to price per gigabyte so kits of different capacities are directly comparable. The full series is downloadable as CSV below.

Methodology
Each day, every in-stock kit RamRadar tracks is normalized to USD price per gigabyte using the lowest live retailer price for that kit. Values outside a plausibility band (unit errors and bad listing matches) are dropped, then the mean, median, and a winsorized 5th–95th percentile band are recorded per RAM type and form factor. Historical rows before the daily aggregation went live were reconstructed from per-product price history with carry-forward of each kit's last known price.
Three things worth knowing before you cite this series. It measures the cheapest price listedfor a kit, not a price anyone was confirmed to have paid, so it is a retail asking-price index rather than a transaction index. Condition filtering is not uniform across sources: eBay listings are restricted to new condition in the API query and re-checked on ingest, while Newegg (via its affiliate product feed) and B&H Photo (from keyword searches of its memory category) are taken as listed, so an open-box or refurbished item from those two can enter the pool. And coverage is not evenly split across retailers. eBay contributes the largest share of tracked offers, then Newegg, then B&H Photo, which means the series reflects those three storefronts rather than the memory market as a whole.
The per-day kit count behind every point ships in the CSV as product_count, so you can see for yourself how thin or thick any given day is before quoting it.
