Intel Arrow Lake Refresh CPUs arrive with native DDR5-7200 CUDIMM support — 12.5% higher speeds than initial Arrow Lake chips

Intel is enhancing memory support with the upcoming Arrow Lake Refresh CPUs, offering native CUDIMM support up to DDR5-7200, a 12.5% speed boost over the initial Arrow Lake chips. While CUDIMM support is improved, standard DIMMs and SO-DIMMs remain at DDR5-5600 and DDR5-6400 respectively. Arrow Lake is the only mainstream lineup fully supporting CUDIMMs, unlike AMD's Ryzen 9000 series which operates them in bypass mode. The Arrow Lake Refresh's IMC may support higher CUDIMMs out of the box, but with DDR5 shortages, finding DDR5-7200 CUDIMM kits may be challenging. Intel's marketing push for Arrow Lake Refresh will likely emphasize this memory enhancement to compete with AMD's Ryzen CPUs.
