DDR4 vs DDR5 on Intel Core i9-12900K Alder Lake @ TechPowerUp
 

The Intel Alder Lake platform has support for both DDR5 and DDR4 memory. We ran 38 application benchmarks and 10 games at multiple DDR4 configurations to learn what performance to expect when using DDR4 vs DDR5 on 12th Gen, and whether there's a point at which DDR4 performance can beat the much more expensive DDR5.
