[News] Rambus Has DDR5 Memory Working in Its Labs, Gears for 2019 Market Release

DDR5, the natural successor to today's DDR4 memory that brings with double the bandwidth and density versus current generation DDR4. along with delivering improved channel efficiency, is expected to be available in the market starting 2019. JEDEC, the standards body responsible for the DDR specifications, says that base DDR5 frequencies should be at around DDR5-4800 - double that of base DDR4's 2400, but a stone throw away from today's fastest (and uber, kidney-like-expensive) 4600 MHz memory kits from the likes of G.Skill and Corsair.

DDR5 is expected to support data rates up to 6.4 Gb/s delivering 51.2 GB/s max, up from 3.2 Gb/s and 25.6 GB/s for today's DDR4. The new version will push the 64-bit link down to 1.1V and burst lengths to 16 bits from 1.2V and 8 bits. In addition, DDR5 lets voltage regulators ride on the memory card rather than the motherboard. CPU vendors are also expected to expand the number of DDR channels on their processors from 12 to 16, which could drive main memory sizes to 128 GB from 64 GB today. Whether this will be good for end-users in relation to DDR5 memory prices remains open for debate; however, considering the rampant memory prices this side of 2017, chances are it won't be unless supply increases considerably.

If market release is not until 2019...then this won't be mainstream until 2020-2021...still a long ways away....

looking at the voltages amd and intel need to work right i doubt we will see ddr5 for non mobile until 2022ish.

Great, so we might have to wait even longer...lol.

Of course there's no word on how DDR5's latency will be compared to DDR4. It always feels like they ignore that in favor of trying to increase density and reduce power usage.

Also: RAMBUS? Good grief won't somebody get rid of them already?!?! Why hasn't JEDEC banned them from involvement in developing group standards?

We need dual Cache w/ some BH-5 @ 2.2.2.5 for low latency tasks and DDR5 for high latency high bandwidth LOL.

what i really want to see is 128bit dimms, we have no reason to stick with 64bit slot interfaces.

on a DFI motherboard? 2.7v+?

Hey I'm all for going back to 2.7v RAM standards for desktops. It would stop phone manufacturers from snapping up all the ICs out there. Nobody wants to burn that much power on memory anymore, though.
