The DDR5 memory requirement, which was formally settled in July 2020 with AMD Ryzen 7000 (“Raphael”) and Intel Core 13000 (“Alder Lake”), just truly begun to gradually change its DDR4 predecessor in the desktop over the previous 2 years, however the upcoming DDR6 memory is currently knocking on the door.

What can we anticipate from the brand-new DDR6 memory requirement– and what dependable info do we currently have? We’ll inform you and supply you with sound background understanding on the next generation of RAM in PCs, servers, and note pads.

DDR6 ought to attain approximately 12,800 MT/s+

Samsung discussed DDR6 and its evolutionary phase DDR6+ at the Tech Day 2021 and exposed lots of intriguing information about the upcoming memory requirement.

If we take the speeds formally authorized by JEDEC as a standard, the optimum information rate was doubled from 3,400 MT/s to approximately 6,400 MT/s with the intro of DDR5 compared to DDR4. Samsung is anticipating a comparable boost for DDR6, which will run at approximately 12,800 MT/s as DDR6-12800.

It ought to be kept in mind that these are just the main requirement speeds defined by JEDEC, which might be far surpassed by overclocked (OC) modules.

Memory sticks to strictly chosen memory modules (“ICs”) ought to for that reason have the ability to attain DDR6-16800 with as much as 16,800 MT/s as OC modules.

The advancement of the DDR memory requirements would then be as follows in regards to pure memory speed:

JEDEC standardOC modulesDDRup to 400 MT/sup to 533 MT/sDDR2up to 1,066 MT/sup to 1,333 MT/sDDR3up to 2,133 MT/sup to 2,666 MT/sDDR4up to 3,200 MT/sup to 5,333 MT/sDDR5up to 6,400 MT/sup to 8,4000 MT/sDDR6 * as much as 12,800 MT/sup to 16,800 MT/s *) not formally validated.

Due to the substantially greater memory speed related to the modification from DDR5 to DDR6, the memory bandwidth likewise increases significantly.

DDR6 has 4 memory channels

The variety of memory channels per module is set to increase to 4 with DDR6, doubling once again compared to DDR5. The variety of memory banks likewise increases by an aspect of 2 to 64, which in turn indicates a fourfold boost compared to DDR4.

In a cross-generational contrast of memory bandwidth, DDR6 would when again increase substantially:

  • DDR as much as 3.2 GB/s
  • DDR2 approximately 8.5 GB/s
  • DDR3 as much as 17.0 GB/s
  • DDR4 approximately 28.8 GB/s
  • DDR5 as much as 67.2 GB/s
  • DDR6 approximately 134.4 GB/s+

As things stand, it can for that reason be presumed that the fastest DDR6 memory modules will have the ability to offer a minimum of 134.4 GB/s of memory bandwidth, with OC modules providing considerably more memory throughput per second.

More functions, less voltage
