The Intel Core 12 will support DDR5 memory at the consumer level for the first time, AMD Ryzen 6000H/U series notebooks will follow, and the Ryzen 7000 series with Zen4 architecture will finish up on the desktop.

However, DDR5 initially has very low frequencies, resulting in little change in performance compared to DDR4, but at a much higher price.

According to the latest news,Ryzen 7000 series partner DDR5 memory has a frequency. Dessert & throughout; , that is 6000MHz, at this time and 3GHz Infinity Fabric bus exactly 1:1 with the same frequency, the best performance.

Keep increasing the memory frequency, and the split will be 1:2, and the performance won't get any better, especially in games.

This andRyzen 3000 DDR4-3800, Ryzen 5000 DDR4-4000The combination is the same.

In addition, a motherboard manufacturer leaked a DDR5 memory optimization guide for AMD X670E platform,AMD EXPO will be supported, you can more easily overclock DDR5 and directly counter Intel XMP 3.0.

DDR5 Settings for the X670E motherboard will also be more detailed. For example, the manufacturer offers a large number of timing options:

Dram ODT impedance RTT_NOM_WR

Dram ODT impedance RTT_NOM_RD

Dram ODT impedance RTT_WR

Dram ODT impedance RTT_PARK

Dram ODT impedance DQS_RTT_PARK
