SK Hynix has reportedly prepared several new DDR5 chips that can achieve a native speed of 7200 MT/s, as spotted on a popular e-commerce platform.
Three More SK Hynix Memory Chips Get Prepared, Offering 7200 MT/s Speed; SK Hynix Reportedly Prepares 2 Gb and 4 Gb Chips as Well
Last week, we reported that SK Hynix is preparing 3 Gb (Gigabit) DDR5 A-Die chips, which are rated for 7200 MT/s, above the current JEDEC standard of 6400 MT/s. It appears that SK Hynix isn't just limiting itself to A-Die 3 Gb chips, but has also silently prepared three more dies, which will offer the same speed, but will be available in different capacities.
As spotted by @unikoshardware, one of the biggest Chinese e-commerce platforms, JD, has listed these new SK Hynix-chip-based DDR5 modules for sale. If you look carefully at the DDR5 chips, you will find new part numbers, which aren't currently available on the market. These reveal that SK Hynix has now prepared a total of four new chips that offer 7200 MT/s speed (denoted by "KB") with densities ranging from 2 Gb to 4 Gb.
| Part Number | Die | Speed | Density |
|---|---|---|---|
| H5CG48CKBD-X030 | C-die | 7200 MT/s | 2 Gb |
| H5CGD8AKBD-X021 | A-die | 7200 MT/s | 3 Gb |
| H5CG58MKBD-X051 | M-die | 7200 MT/s | 4 Gb |
| H5CC48BKBD-X030 | B-die | 7200 MT/s | 2 Gb |
SK Hynix has, for the first time, introduced a 2 Gb B-die, but has also introduced a new capacity in the M-die. The new M-die will boast 4 Gb capacity, which is the first time this process node is available in this capacity. While 4 Gb density is relatively small compared to 16 Gb or 24 Gb dies used in high-capacity DDR5 modules, it could be targeted at high-speed, lower-density DDR5 configurations.
That said, as we previously said, such high-speed DDR5 RAM modules will need at least a 10-layer or 12-layer PCB to sustain high speeds, particularly when overclocked. These might be the first samples by SK Hynix, and one should expect a higher-layer PCB for better signal integrity soon. SK Hynix hasn't officially announced the availability of these new 7200 MT/s memory chips, but no doubt, it has already prepared some.
