DDR5 vs. DDR4 Memory CostsThe Intel Z690 chipset supports both DDR4 and DDR5 memory, so customers will be able to continue to use DDR4 memory by opting for a DDR4-based Z690 motherboard.
Historically, newer memory technology has always commanded close to a 30-40% premium over the previous generation. However, this time, DDR5 includes additional components that have driven the costs up further. As a result, we expect a 50-60% price premium compared to DDR4 at launch.
It typically takes around 2 years to reach price parity with previous generations, and we expect trends to remain similar with DDR5 modules as well.
