SK Hynix's new DDR5 memory chip recently appeared on the Internet, said to be code-named "X021" and carrying a new part code "AKBD". According to unikoshardware,The "X021" marking on the chip indicates that it is a second-generation 3Gb A-Die chip that will replace the 3Gb M-Die currently used in early DDR5 memory modules.
Although SK Hynix has not officially released this second-generation 3Gb DDR5 A-Die, according to its past naming convention (such as EB, GB, HB and other codes correspond to the JEDEC standard frequencies of 4800, 5600 and 6400MT/s respectively),The new "AKBD" may correspond to the native frequency of 7200MT/s, and the sharer also confirmed in the communication that the native frequency is 7200MT/s.
The emergence of this new generation of memory specifications is highly consistent with Intel's future platform roadmap. According to the plan, Intel's future Arrow Lake Refresh and Panther Lake processors are expected to support native DDR5-7200 memory.
This is another step up from Raptor Lake’s DDR5-5600 and Arrow Lake’s DDR5-6400. This indicates that SK Hynix’s A-Die “AKBD” chip is expected to be tailor-made for the upcoming Intel processor platform.
