What is the latest RAM standard that can operate at bandwidths up to 12,800 Mbps?

The RAM standard capable of operating at bandwidths up to 12,800 Mbps is DDR4, specifically the DDR4-2400 variant. DDR4 memory significantly improved performance over its predecessor, DDR3. While DDR3-1600 might suggest some high performance, it operates at a maximum bandwidth of only 12,800 Mbps. DDR4-2400 actually doubles this with its capability for higher speeds due to better bandwidth efficiency and architecture.

DDR4 brought enhancements such as increased module density and lower power consumption compared to DDR3, enabling better overall system performance for various applications including gaming, multimedia, and server environments. You can find that DDR5 further improves speed but operates at even higher standards beyond the reach of the 12,800 Mbps classification reflected in DDR4-2400.
