Samsung Announces First LPDDR5 DRAM Chip, Targets 6.4Gbps Data Rates & 30% Reduced Power [anandtech.com]

[Samsung] is announcing that they have completed fabrication, functional testing, and validation of a prototype 8Gbit LPDDR5 module. The company is targeting data rates up to 6.4Gbps-per-pin with the new memory, and while Samsung isn't ready to start mass production quite yet, the company's press release notes that they're already eyeing it.

[...] In terms of performance, Samsung is targeting up to 6.4Gbps/pin with the new memory. Which for a typical 32-bit bus chip works out to 25.6GB/sec of memory bandwidth. This is a 50% increase in bandwidth over the current LPDDR4(X) standard, which tops out at 4.266Gbps under the same conditions. So for a high-end phone where 64-bit memory buses are common, we'd be looking at over 50GB/sec of memory bandwidth, and over 100GB/sec for a standard 128-bit bus PC.
