SK Hynix is getting ready to make DDR5-8400 memory
Over 130 GB/s peak theoretical performance in a dual-channel configuration
April 5, 2020
https://www.techspot.com/news/84700-sk-hynix-getting-ready-make-ddr5-8400-memory.html

Unlike the iterative upgrades that define the successive releases of most PC parts, memory upgrades are significant. DDR4 is now six years behind the times and DDR5 is bound to make it utterly obsolete. SK Hynix has thoughtfully warned us ahead of time, with an impressive roster of new specs and a rough release schedule.

The headlining feature is the raw speed: up to 8400 MT/s. At that speed, the per-channel theoretical bandwidth is 67.2 GB/s, which a lot more than DDR4’s rated maximum of 25.6 GB/s.
A typical dual-channel configuration will offer 134 GB/s. Quad-channel 267 GB/s; octa-channel 538 GB/s. Real-world speeds tend to be about 30% lower in practice though.
Beyond speed, there’s a whole stack of other technologies.

JEDEC releases next-gen DDR5 memory specification
Bigger, better, faster, a bit more expensive than DDR4
July 16, 2020
https://www.techspot.com/news/86000-jedec-releases-ddr5-memory-specification.html

Something to look forward to: As CPU core counts continue their upward trend, there's been a pressing need to improve DRAM bandwidth as well. DDR5 SDRAM will quadruple capacity per die and double the effective bandwidth, all while lowering power consumption thanks to architecture refinements.

The JEDEC Solid State Technology Association has announced the final DDR5 memory specification with a series of significant upgrades over the previous standard that is now over six years old and in dire need of a worthy replacement. After all, the standards body took two years more than originally planned to align what's coming next to the growing needs of system manufacturers.

The DDR5 SDRAM standard quadruples the density of DDR4, going from 16 Gb per die to 64 Gb. This will allow manufacturers to make DIMMs with capacities going all the way up to 2 TB.
In terms of maximum data rate, DDR5 will offer 6.4 Gbps, or double the data rate of DDR4. However, the first modules to hit the consumer market will only be capable of reaching 4.8 Gbps, which is still a significant improvement over the 3.2 Gbps maximum of DDR4.

SK Hynix launches first DDR5 DRAM modules
The initial products will be for enterprise use
October 6, 2020
https://www.techspot.com/news/86997-sk-hynix-launches-first-ddr5-dram-modules.html

What just happened? We've been hearing about the technology for a number of years now, but SK Hynix has finally announced the launch of the first DDR5 DRAM modules. These initial products won't be targeting gamers, though; instead, they're designed for big data, artificial intelligence, machine learning, and other enterprise applications.

The Korean semiconductor giant announced back on November 28, 2018, the development of the world's first 16 Gigabit (Gb) DDR5 DRAM. The company says its DDR5 supports speeds between 4,800 MHz and 5,600 MHz, making it around 1.8 times faster than most standard, non-overclocked DDR4 kits.
SK Hynix says that despite the increased speeds, DDR5 will run 0.1V lower than DDR4, dropping from 1.2V to 1.1V.

While there was no mention of the first DDR5 modules' capacity, SK Hynix said they could eventually reach 256 GB by using chip-stacking through-silicon-via (TSV) technology.

"Intel partnered closely with memory leaders including SK Hynix on the DDR5 spec development starting with early architecture concepts through JEDEC standardization," said Carolyn Duran, Vice President of Intel's Data Platforms Group and GM of Memory and IO Technologies.
"In addition, we worked collaboratively with SK Hynix on silicon development by designing and testing prototypes to ensure DDR5 meets its performance goals and are fully ready for our mutual customers."

Team Group develops their first "Consumer-Grade" DDR5 memory modules
DDR5 memory has already been sent to motherboard makers for validation
December 15, 2020
https://overclock3d.net/news/memory...ir_first_consumer-grade_ddr5_memory_modules/1

2021 will mark the start of the DDR5 era, delivering to consumers faster memory which draws less power and delivers new features to the long-lived DDR memory standard.

Next year, Team Group plans to release ELITE series DDR5 modules, with their first batches delivering 16Gb modules with 4800MHz frequencies at 1.1v. These early batches are already in production, and modules have already been sent to motherboard manufacturers like ASUS, MSI and Gigabyte for validation.
Completing this validation phase should confirm that the frequencies of standard DDR5 memory modules will surpass those of today's overclocked DDR4 DIMMs, highlighting the leap that DDR5 delivers over today's memory technology.

DDR5 RAM will be much faster than DDR4, but it comes with one major compromise
August 6, 2021
https://www.digitaltrends.com/computing/corsair-ddr5-ram-requires-much-better-cooling/

DDR5 memory is on the horizon, and leading manufacturers are gearing up for its release. Corsair is one of the brands that is preparing to release DDR5 RAM soon. The company revealed more about the possibilities of DDR5 RAM, as well as some of the difficulties, including the fact that it will run much hotter than DDR4.

The warm-up is not a surprise. The best RAM in the DDR5 lineup is going to be up to 4 times more powerful than its predecessor, thus generating more heat. However, according to George Makris, Corsair’s DIY Marketing Director, the reason also lies in the design of the memory module itself.

“DDR5 conceivably could run much hotter than DDR4, as they have moved voltage regulation off the motherboard itself, and now it is on the [RAM module], so you actually could be pumping a lot more heat,” said George Makris in a YouTube video posted on Corsair’s channel.

If If If this same new breakthrough DDR5 RAM Memory can also be satisfactory replacement for older machines that would indeed be a milestone. Most current trends as expected sour on older machines and suggest throw them away for new hardware and that does make sense of course. But imagine how much more folks/user's who been tied down with limitations of memory on older machines could be made more encouraged to purchase newer PC's if only they could realize some performance pickup on those older types and not feel they are of little use anymore. Compatibility means everything even where concerns computers that seemingly have hardware limitations that have been stuck at a particular level with no other choice but to either ditch it or settle for mediocre performance.

DDR5 memory, according to MSI, will cost 50 to 60 percent more than DDR4 memory
October 21, 2021
https://www.guru3d.com/news-story/d...t-50-to-60-percent-more-than-ddr4-memory.html

Some firms have been selling DDR5 memory kits for almost three months already, indicating that there is no longer a prohibition on the technology.
But how much would DDR5 memory set you back financially?

DDR5 vs. DDR4 Memory Costs
Historically, newer memory technology has always commanded close to a 30-40% premium over the previous generation. However, this time, DDR5 includes additional components that have driven the costs up further. As a result, we expect a 50-60% price premium compared to DDR4 at launch.
It typically takes around 2 years to reach price parity with previous generations, and we expect trends to remain similar with DDR5 modules as well.
— Sara Lin, MSI
MSI expects that DDR5 memory will be 50-60 percent more expensive than DDR4 memory when it first becomes available. The company estimates that it will take two years to achieve price parity with the previous standard.

DDR5 is too expensive so ASUS makes a DDR5 to DDR4 adapter for Intel Alder Lake
December 30, 2021

The 600 series chipset motherboards for Intel's Alder Lake-S come in a couple of flavors offering both DDR5 and DDR4 motherboard options.
However, DDR5 desktop DRAM right now is nearly impossible to get as stocks are low and prices are exorbitant. On places like eBay, scalpers are demanding up to $5,000 for DDR5 kits.

So for those who have already bought a DDR5 motherboard, ASUS has devised a new adapter that can fit a DDR4 kit onto a DDR5 motherboard.
Although the product still appears to be a prototype, it will be interesting to see if ASUS really brings it to the market and at what price.
