American semiconductor company Micron Technology has announced that it has started mass production of high-capacity 96GB DDR5 RDIMMs that can deliver speeds of up to 4800MT/s. Workstations and server-side memory are also designed to handle AI and in-memory database workloads. Micron also claimed to eliminate the need for die stacking, which increases both cost and latency in new memory.Micron begins mass production of 96GB DDR5s
Micron’s 96GB DDR5 RDIMM modules support AMD’s 4th generation EPYC processors and are used in the Supermicro 8125GS, an AMD-based system designed for high performance computing, artificial intelligence and deep learning training and industrial server workloads. Micron states that systems with 4th generation AMD Zen 4 processors and Micron DDR5-4800MT/s memory modules can achieve results 2 times faster than devices with AMD’s 3rd generation Zen 3 processors and Micron DDR4-3200MT/s modules. states.DDR5 comes with a number of inherent advantages over DDR4, such as higher base speed and lower power consumption. The default clock speed for DDR4 is 2133MHz, while the base frequency for DDR5 modules has been increased to 4800MHz. DDR5 can also support higher capacity DIMM modules. Theoretically, DDR5 can support up to 512GB per module, but current generation processors from Intel and AMD can only address DDR5 memory up to a total of 128GB.
Despite all the advantages of DDR5, there are still important areas where DDR4 is ahead. Most importantly, DDR4 has lower latency than DDR5, meaning that systems with DDR4 memory could theoretically be faster and more responsive than computers with DDR5. DDR5 latency is getting better over time, but time will tell if it can catch up with DDR4 in this regard.
