At the moment SK Hynix is saying the sampling of its subsequent technology DDR5 reminiscence. The headline is the commercialization of a brand new 24 gigabit die, providing 50% extra capability than the main 16 gigabit dies presently used on high-capacity DDR5. Together with reportedly lowering energy consumption by 25% through the use of SK Hynix’s newest 1a nm course of node and EUV know-how, what fascinates me most is that we’re going to get, for the primary time within the PC area (to my information), reminiscence modules which might be now not powers of two.

.

For PC-based DDR reminiscence, all the best way again from DDR1 and prior, reminiscence modules have been configured as an influence of two when it comes to storage. Whether or not that’s 16 MiB to 256 MiB to 2 GiB to 32 GiB, I’m pretty sure that all the reminiscence modules that I’ve ever dealt with have been powers of two. The brand new announcement from SK Hynix showcases that the brand new 24 gigabit dies will permit the corporate to construct DDR5 modules in capacities of 48 GiB and 96 GiB.

To be clear, the DDR5 official specification truly permits for capacities that aren’t direct powers of two. If we glance to different sorts of reminiscence, powers of two have been thrown out the window for some time, akin to in smartphones. Nonetheless PCs and Servers, as least the standard ones, have adopted the facility of two mantra. One of many adjustments in reminiscence design that’s now driving common modules to non-power of two capacities is that it’s getting tougher and tougher to scale DRAM capacities. The time it takes to determine the complexity of the know-how to get a 2x enchancment each time is simply too lengthy, and reminiscence distributors will begin taking these intermediate steps to get product to market.

In conventional vogue although, these chips and modules will likely be earmarked for server use first, for ECC and RDIMM designs. That’s the market that may soak up the early adopter price of the {hardware}, and SK Hynix even says that the modules are anticipated to energy excessive efficiency servers, notably in machine studying in addition to different HPC conditions. One of many quotes on the SK Hynix press launch was from Intel’s Knowledge Middle Group, so if there’s any synergy associated to help and deployment, that’s most likely the place to begin. A server CPU with 8x 64-bit channels and a pair of DIMMs per channel provides 16 modules, and 16 x 48 GiB permits 768 GiB capability.

As to when this know-how will come to the buyer market, we’re going to need to be aware of price and assume that these chips will likely be used on high-cost {hardware}. So maybe 48 GiB UDIMMs would be the first to market, though there’s a small chance 24 GiB UDIMMs would possibly make an look. Abruptly that 128 GiB restrict on a contemporary gaming desktop will develop to 192 GiB.
