JEDEC is poised to announce the next-gen memory standard (DDR5) later this year, and has confirmed a few details for us: “DDR5 will offer improved performance, with greater power efficiency compared to previous generation DRAM technologies. As planned, DDR5 will provide double the bandwidth, and density over DDR4, along with delivering improved channel efficiency.”
That’s exciting, if only for the fact that power consumption should drop—DDR3 sat at 1.5V and DDR4 at 1.2V, so it’s likely we’ll see DDR5 at 1.0V or lower. The doubling of density means we’ll likely see mobos double in max capacity, too, with mainstream platforms maxing out at 128GB, and high-end desktops hitting a 256GB limit. Expect initial MT/s figures to hit around 4,133MT/s, with latencies at 27ns if not more. However, it’s unlikely to come into production until late 2019.
