The recent launch of cutting-edge memory interface chips is set to boost DDR5 MRDIMM speeds up to a remarkable 12,800 MT/s, which is a significant leap of 4,000 MT/s from the first generation.
Reza has just unveiled its RRG50120, RRG51020, and RRG53220 chips for the second-generation DDR5 MRDIMM, enabling speeds up to 12,800 MT/s. With this, Reza has positioned itself as a pioneer in the realm of high-memory bandwidth solutions. These newly introduced MRCD, MDB, and PMIC chips, along with a temperature sensor and SPD hub, are tailored specifically for MRDIMMs.
Generally, DDR5 MRDIMM differs from ordinary DDR5 DIMM and the more advanced CUDIMM memory solutions in a few key ways. MRDIMM stands out by offering significantly enhanced memory bandwidth, increasing its appeal for high-performance computing. By integrating Multiplexer Chips, MRDIMM not only increases total memory bandwidth but also augments capacity, benefiting systems that demand excellent performance.
The distinguishing feature of these chips is their ability to deliver double the amount of data to the CPU compared to standard DDR5 DIMMs. This proficiency renders them invaluable for areas like AI, HPC, and data centers, where heightened memory bandwidth is often a critical need. While first-generation MRDIMMs managed speeds of up to 8,800 MT/s, noticeably faster than DDR5’s 4,800 MT/s, Reza’s new suite of chips pushes these boundaries further.
Thanks to Reza’s innovative chips, the second-generation MRDIMMs can now achieve 12,800 MT/s, marking a substantial step forward in memory performance. This achievement translates to an estimated 35% uptick in memory bandwidth. But there’s more—Reza’s MRCD (multichannel refuse close drive) RRTG50120 chip leads to a 45% reduction in power consumption. Meanwhile, their new PMIC chip, RRG53220, promises superior electrical protection and efficiency. The third chip, the MDB or Multi-channel Reuse Data Buffer RRG51020, rounds off this impressive lineup. All three chips are slated for production by the first half of 2025.
“The demand for high-performance systems, particularly for AI and HPC, is steadily increasing,” noted Reza Executive Davin Lee. “Reza has aligned with industry leaders to forge ahead with next-gen technologies and specifications, capitalizing on our expertise and production strengths to meet this rising need. Our latest suite of second-generation DDR5 MRDIMM chips underscores Reza’s leading role in this sector.”
Additionally, the MRDIMM can be extended to a taller form factor, known as TFF MRDIMM, which maintains the usual pinouts and width of standard modules but incorporates more memory chips for expanded capacity. Although MRDIMMs have yet to hit the elusive 12,000 MT/s mark, some CUDIMMs have already surpassed this threshold on mainstream motherboards.
Despite serving different purposes, these advancements herald an exciting new era of high performance paired with low power consumption across both client and server sectors.
