Ram prices did not move as one market last week.
RamRadar's August 14 price index puts the average desktop DDR4 price at $7.5454 per GB, down 2.04% from August 7. Desktop DDR5 moved the other way: $15.0446 per GB, up 1.90% over the same period. That leaves desktop DDR5 about 99.4% more expensive per GB than desktop DDR4 in the latest snapshot.
The index included 96 tracked DDR4 DIMM products and 192 DDR5 DIMM products on August 14. That is enough to describe direction, but not enough to turn an average into a buying command for every kit. Individual prices still depend on capacity, speed, latency, form factor, retailer, and stock.
The practical takeaway is simple: compare a kit with its own history before trusting a sale badge. RamRadar's near-ATL page highlights products trading close to their recorded low, while the timing guide explains when it makes sense to buy now and when to set an alert instead.
For a new desktop build, the DDR4-versus-DDR5 question is usually decided by the motherboard. For an existing DDR4 machine, current availability matters more than a generic “DDR4 is cheaper” rule. RamRadar's comparison guide keeps the platform decision separate from the live price comparison.
The full index includes daily averages, medians, ranges, product counts, historical charts, and a CSV download. The data is there so you can check the market yourself instead of taking a paragraph like this on faith.
