Samsung has announced a major breakthrough in DDR5 SDRAM design from Manufacture of a 512 GB DDR5 DIMM. Not only is it the most spacious RAM stick in the world, but Samsung also took first place in the Speed Stakes, as the new sticks manage a ridiculous 7,200 Mbit / s.
This was made possible by Samsung’s TSV technology (which confusingly stands for Through Silicon Via), which allows eight memory chips to be stacked on top of one another. HKMG (High-K Metal Gate) materials are also used, which are traditionally reserved for logic semiconductors and not for memory. It is used here as a replacement for the usual insulation layer, since older insulation layers have become too thin with increasing density, which leads to a higher leakage current.
HKMG was first used by Samsung in 2018 in its GDDR6 memory that you can find on many graphics cards. Proof that GPUs are truly at the cutting edge of technology – if such evidence were required.
This new storage system also uses around 13 percent less electricity. This is the kind of saving that matters where it’s used: in data centers.
It’s fair to say that we probably don’t need 512 GB memory modules in our gaming machines, and in fact most desktop processors have significantly lower capacity limits anyway (64 GB or 128 GB, depending on your CPU).
No, these modules are designed for serious, high bandwidth workloads and are used in medical research, the financial market, autonomous driving, etc. Samsung is reviewing Intel and its scalable Sapphire Rapids Xeon processors in the press release for this new memory.
It’s still very early on for DDR5, which offers twice the bandwidth of DDR4 and lower power consumption, but there aren’t any consumer platforms to support it yet. DDR5 was officially released back in July 2020, almost two years late, but there was no rush to endorse it as DDR4 has enough bandwidth for most consumer establishments.
The first consumer platform to support DDR5 is expected to be Intel’s Alder Lake, slated for release in early 2022. AMD’s Zen 4 architecture also supports DDR5 and will be due shortly after Alder Lake in the summer of 2022. Samsung is pushing for it It’s so difficult to develop that hopefully we’ll have a wide range of speeds and capacities when it comes to our gaming PCs.
