DDR5 big difference?

[Gamer Schnitzel]

I was going to build a new PC when the 3000 series comes out of NVIDIA's new cards but I heard that Samsung will be releasing DDR5 memory next year so now I wonder if it is worth waiting until then.

I don't mind waiting but wondered if it is worth waiting for DDR5. Does RAM make a big difference?

I know that Ryzen depends heavily on RAM so I assume that for Ryzen DDR5 will make a steep difference in speed?

DDR5 will be available in 2022 earliest for the masses. So far both Intel and AMD are on DDR4 for this and the next generations of CPUs. Best option would be to build towards Q3 when both Zen3 (Ryzen 4000) and RTX 3000 are available

ddr5 will also require a new motherboard and new cpu series. for AMD, the upcoming 4000 series will still be on AM4 with DDR4. the 5000 series, likely on AM5 and DDR5 hasn't been announced yet and I don't see it coming before end of 2021/beginning of 2022. I don't see intel releasing anything able to utilise DDR5 by then either.

Well, before DDR5 ram will be used in consumer electronics it will take a lot longer, so my guess is 3+ years before its accessible and affordable. I guess it all comes down to whether you need a PC or not. There's always something new that is going to be released and that way you would end up waiting endlessly .

It's gonna be 2022 most likely, you may have ddr5 chips used in phones (with SoC's) before that, for power saving reasons, but ram sticks are probably gonna be in 2022 when it would be about time for new server processors..

 

 

Cadence DDR5 Update: Launching at 4800 MT/s, Over 12 DDR5 SoCs in Development

Samsung to Produce DDR5 in 2021 (with EUV)

Micron and SK Hynix have already announced sampling to partners of their DDR5 memory modules based on their 16 Gb chips. Samsung has not formally confirmed any sampling, but we know from its ISSCC 2019 announcement that the company has been preparing and evaluating its 16 Gb DDR5 devices and modules on internally for a while now. Anyhow, DDR5 will likely be available at launch from all three major DRAM producers.

 

Cadence is confident that DDR5 ramp will begin with 16 Gb DRAMs at 4800 MT/sec/pin data transfer rate (something that was indirectly confirmed by SK Hynix’s DDR5-4800 module showcase at CES 2020). From there, DDR5 will evolve in two directions: capacity and performance. Capacity wise, DDR5 will grow to 24 Gb (so expect DDR5 modules of odd capacity like 24 GB, 48 GB, etc.) and then to 32 Gb. As for performance, Cadence expects DDR5 to evolve to 5200 MT/sec/pin data rate in 12 – 18 months after DDR4-4800 launch and then to 5600 MT/s in another 12 – 18 months, so performance progress of DDR5 in servers will occur in a pretty much regular cadence.

DDR5 Shipping This Year?

As noted above, AMD’s Genoa and Intel’s Sapphire Rapids are not due until very late 2021, or rather early 2022, but Cadence seems to be optimistic and believes that ‘2020 will be the year of DDR5’. From Cadence’s perspective, this might mean tapeouts of actual DDR5-supporting SoCs (which is about time), but the company’s internal analysis shows that it expects DRAM vendors to actually start shipments of DDR5 memory this year.

Samsung is on track to start volume production of DDR5 and LPDDR5 memory next year using a manufacturing technology that will take advantage of extreme ultraviolet lithography (EUVL). In fact, Samsung has been playing with EUV-enabled DRAM fabrication process for a while and has already validated DDR4 memory with select partners.

To date, Samsung has produced and shipped a million of DDR4 DRAM modules based on chips made using the company’s D1x process technology that uses EUV lithography. These modules have completed customer evaluations, which proves that Samsung’s 1^st Generation EUV DRAM technology enables to build fine circuits. Samsung’s D1x is an experimental EUVL fabrication process that was used to make experimental DDR4 DRAMs, though it will not be used any further, the company said.

Instead, to produce DDR5 and LPDDR5 next year, the company will use its D1a, a highly-advanced 14 nm-class process with EUV layers. This technology is expected to double per-wafer productivity (DRAM bit output) when compared to D1x technology, which indicates that it uses thinner geomtries.

Okay thanks guys, so I won't have to wait for another year. I'll just wait for Q4 this year then.
