Samsung gives us long teeth with its 512 GB DDR5 modules, but forget it: for the moment they are destined for data centers
Little by little we are finally leaving behind that unwritten rule that seemed to dictate that portable PCs they had to be sold with 8 GB of RAM as hell. We see more and more computers with 16GB configurations, but the figure stays small to see what has been pulled from Samsung’s sleeve.
This manufacturer, leader in semiconductors and memories, has announced the development of 512GB DDR5 modules, a really remarkable figure that nonetheless only serves to make us envious. These modules are intended for data centers and supercomputing.
Envisioning a Future with 512GB 1TB RAM PCs and Laptops
These modules are developed with HKMG technology (High-K Metal Gate), which was already used in GDDR6 memory modules for graphics in 2018 and is now beginning to be applied to DRAM memory modules.
Thanks to this technology it is possible to reduce energy leaks and improve performance: they consume up to 13% less energy and achieve transfers of up to 7,200 Mbps. All of these capabilities are clearly intended for data centers and supercomputing centers that require huge amounts of memory to meet their computing needs.
Each of these modules uses eight layers of 16 Gbit DRAM chips, making each layer capable of 128 Gbits (or 16 GB). The features of these modules allow a total of 57.6 GB / s bandwidths can be handled on a single channel, but they will also be compatible with the future ‘Sapphire Rapids’ architecture of future Intel Xeon.
That architecture makes use of an eight channel DDR5 memory controller, which means we could see systems with several “teras” of memory and transfer speeds of 460 GB / s.
When will something like this reach our PCs and laptops? Our teams are still anchored in DDR4 modules for the moment, but attentive because expected that in 2022 AMD present its Zen 4 microarchitecture, successor to the actual Zen 3.
I know rumored that this microarchitecture will support memory modules DDR5, which will pose that first step so that in the future not too far we have access to PCs and laptops in which Having 512 or 1 TB of RAM may not be far-fetched.
