Intel Raptor Lake: ‘MSI’s Z790 motherboards compatible with DDR5-6800’

In addition to AMD, Intel also seems to be planning to support higher memory speeds on its upcoming CPU platform. For example, Videocardz has obtained specifications of some Z790 motherboards from MSI, in which both ddr5 and ddr4 are discussed.

While Alder Lake can handle 4,800 MT/s by default in the case of ddr5, a document surfaced indicates that Raptor Lake supports the JEDEC standard of 5,600 MT/s (+16.6%). This rate applies to two dual-rank dimms per memory channel. As the amount of bars per channel and the number of ranks decrease, higher speed is possible: a single single-rank module must be able to reach at least 6,800 MT/s. The Z690 Godlike, MSI’s Z690 flagship, achieves 6,666 MT/s here.

The speed limit is also raised with ddr4, although the difference is less significant: an unnamed Z790 board reports 5,333 MT/s when one single-rank dimm is used per channel. Existing Z690 boards such as the Edge and Tomahawk are promised a maximum of 5,200 MT/s. Configurations with two dual-rank slats per channel should be able to reach a minimum of 4,000 MT/s with both the Z690 and its successor.

It remains to be seen whether Intel will offer faster speeds than AMD’s first AM5-based motherboards. So far, only Biostar has released more information about an X670E board, claiming at least 6,000 MT/s. More details are likely to come to light during the official Ryzen 7000 series unveiling early next week.
