G.SKILL has already announced its latest memory kits based on the latest type of DDR5 DRAM. It is rated to go up to 6,400MHz; however, the OEM now claims to have something that improves on even this new top-end product in the works already. It asserts that these new fastest-ever memory sticks are DDR5-7000.
This implies scope for up to 7,000 megatransfers per second (MT/s) in this new form of RAM. G.SKILL also notes that it has an "ultra-low" CAS latency of CL40-40-40-76, and satisfies Memtest stability requirements. Accordingly, the OEM suggests that this RAM is too fast even for the Extreme Memory Profiles Intel currently specifies for Alder Lake.
G.SKILL also tops these rankings with its DDR5-6666 CL40 RAM sticks. On the other hand, it has yet to mention anything resembling a launch or release date for its apparent successor. The company has revealed that it exists as a 2x16GB kit at present, and is made of "high-performance" chips from Samsung. Nevertheless, cracking this new record may be an encouraging sign of what might be available to those looking to build upgrades based on next-gen CPUs one day.
