DDR5 memory is coming, but like previous standards, the specifications of the initial version are not too high, the frequency is only 4800MHz, coupled with higher and higher latency, we are all looking forward to stronger specifications.
Today, the JEDEC organization officially released the upgraded version of the JESD79-5A DDR5 SDRAM memory standard specification, which is specifically aimed at the field of HPC high-performance computing, including higher frequency and performance, as well as various stability and reliability enhancements.
The high-performance computing version of the DDR5 memory standard was released as early as July last year, numbered JESD79-5. This upgraded version further expands the transmission speed. The core speed supports up to 6400MT/s, the IO AC speed up to 5600MT/s, and the actual frequency The highest is 5600MHz, which is nearly 17% higher than consumer-grade DDR5-4800.
At the same time, the new standard also supports a series of industry-standard technologies that can improve system stability, including edge error correction, soft post-package repair (sPPR) undo and lock, memory built-in self-test post-package repair (MBIST/mPPR), adaptive RFM, MR4 extension.
AMD, Samsung, Micron, and SK Hynix all expressed their welcome and support for the new standard.
