Analysts are predicting a fast ramp for DDR5 by 2023 subsequently it debuts in the server market concluding yr. If these predictions are accurate, DDR5 would ramp much more quickly than DDR4 did when information technology launched.

Micronews, via THG, predicts that DDR5 will launch at the tail end of this twelvemonth and then scale rapidly in 2022 thanks to widespread adoption in the server market. In 2023, DDR5 goes fully mainstream and begins pushing DDR4 out of the entire PC space.

These predictions line up with what nosotros've heard elsewhere, though there'south some potential ambiguity as to why. DDR5 is referred to every bit having higher BOM (Neb of Materials) costs than DDR4 in some articles and lower in others. What we suspect is that long-term DDR5 BOM costs are expected to come up in below DDR4, merely every memory engineering carries a premium at introduction and DDR5 is no different in that regard.

Is a Fast DDR5 Ramp Probable?

The just fashion for DDR5 to surge into market the way Micronews expects is if AMD and Intel make a major push to migrate to the new standard by late 2022 and continue it into 2023. The initial wave of server adoption expected for late 2021-2022 makes sense. Intel will introduce DDR5 with Sapphire Rapids and Sapphire Rapids is expected to offer much more competitive core counts compared with 2d or fifty-fifty 3rd Gen Xeon Scalable processors.

The relatively quick spring from a maximum of 28 cores per socket to 72-80 cores per socket could unleash some pent-up need for hardware on the Intel side of the equation. AMD's Genoa isn't expected to make quite the aforementioned spring in core count — rumor suggests a 96-core CPU, up from 64 — but that would be plenty to maintain AMD's cadre count advantage against Intel. Once again, this kind of upgrade could unleash some additional interest on the AMD side as well.

DDR5 supports higher die densities (upward to 64Gb, compared with 16Gbb) and it'due south expected to hit DDR5-6400 clock speeds quickly. Retention companies accept already teased significantly higher clocks. Memory subsystem changes haven't historically boosted PC performance much at launch, though it'south possible that the clock leap DDR5 brings compared with DDR4 will open up a small gap between the new RAM standard and its predecessor.

As always, PCs with integrated graphics volition benefit the most from faster DDR5, especially AMD APUs. A dual-channel organization with DDR5-6400 would offering 102.4GB/s of memory bandwidth — double the 51.2GB/s y'all'd get from the same chip today.

The big question in all of this is whether demand in the PC market will autumn by a larger than expected amount when pandemic-related demand inevitably cools. If it does, information technology could accept DDR5 a bit longer to supplant DDR4, putting it on more than of an equivalent timeline to DDR4's overall replacement of DDR3.
