This level of performance, according to the company, represents a 17% increase in data rate over the first-generation 4800 MT/s DDR5 RCD. With the addition of a number of key innovations, Rambus has been able to deliver 5600 MT/s performance at lower latency and power while optimising timing parameters for improved RDIMM margins.
“Advanced workloads are driving an insatiable demand for greater memory bandwidth,” said Shane Rau, research vice president, Computing Semiconductors at IDC. “It’s essential that DDR5 ecosystem players like Rambus continue to raise the bar on performance to meet the rapidly rising needs of data centre applications.”
“The RCD is a mission-critical enabler of DDR5 server DIMMs that provide the bandwidth and capacity needed in next-generation data centres,” said Sean Fan, chief operating officer at Rambus. “Achieving the 5600 MT/s data rate is the latest demonstration of our continued leadership in DDR5 memory interface products.”
With DDR5 memory, more intelligence is built into the DIMMs enabling up to double the data rate and four times the capacity of DDR4 DIMMs, while at the same time reducing power and increasing memory efficiency.
