Samsung's 512GB DDR5 module is a showcase for the future of RAM:

Samsung has unveiled a new RAM module that shows the potential of DDR5 memory in terms of speed and capacity. The 512GB DDR5 module is the first to use High-K Metal Gate (HKMG) tech, delivering 7,200 Mbps speeds — over double that of DDR4, Samsung said. Right now, it's aimed at data-hungry supercomputing, AI and machine learning functions, but DDR5 will eventually find its way to regular PCs, boosting gaming and other applications.

[...] With 7,200 Mbps speeds, Samsung's latest module would deliver around 57.6 GB/s transfer speeds on a single channel. In Samsung's press release, Intel noted that the memory would be compatible with its next-gen "Sapphire Rapids" Xeon Scalable processors. That architecture will use an eight-channel DDR5 memory controller, so we could see multi-terabyte memory configurations with memory transfer speeds as high as 460 GB/s. Meanwhile, the first consumer PCs could arrive in 2022 when AMD unveils its Zen 4 platform, which is rumored to support DDR5.
