From PC Mag: South Korean semiconductor manufacturer SK Hynix is celebrating today after it announced the world's first 64GB DDR5 RAM modules, paving the way for data centers and desktops alike to start moving away from DDR4.
The official DDR5 memory specification was published by the JEDEC Solid State Technology Association back in July, but SK Hynix has been working on DDR5 memory since 2018 when it developed the world's first 16Gb DDR5 DRAM., It's therefore not surprising to see them announce the world's first DDR5 DRAM chips today on a 64GB memory module as shown in the image above.
In terms of performance, DDR5 holds the promise of some major gains both in terms of speed and capacity. SK Hynix says its DDR5-4800 chips, which support transfer speeds of between 4,800-5,600Mbps, are 1.8x faster than DDR4 while at the same time requiring 20 percent less power. Using the company's through-silicon-via (TSV) technology, it's also claimed we could see 256GB memory modules appear.
As Anandtech explains, the big changes DDR5 brings includes switching from a single 64-bit data channel to two 32-bit channels, and voltage regulation is moving from the motherboard to the memory module. Combined, it allows for more control over data rate improvements and speed of modules by the individual vendors, paving the way for some very fast "above specification" modules in future.
