Samsung Develops 512 GB DDR5 Memory Modules Running at 7.2 Gbps
At this year's Hot chips 33 conference, Samsung has presented its works on the upcoming DDR5 memory standard. The company has managed to achieve a lot of new developments, as the newer standard pairs with new technologies to deliver higher speeds and better capacity. The Korean company designed its DDR5 modules as 8-high (8H) stacked TSV (through silicon via) dies. In the previous DDR4 implementations, Samsung used 4-high (4H) stacked TSV dies, which are actually thicker than the latest 8-high implementations. To achieve the new thin design, Samsung has used thin wafer handling techniques, which resulted in a 40% reduction in gab between stacked dies. The new 8H DDR5 modules are only 1.0 mm thick, compared to the 1.2 mm of the older 4H modules.
When it comes to performance, Samsung expects the new DDR5 modules to deliver big. Running at 7.2 Gbps speeds, the Samsung-made RDIMM/LRDIMM modules can reach up to 512 GB in capacity. This is, of course, limited to the server/enterprise market. Regular consumers/PC users can expect to have UDIMMs with up to 64 GB of capacity. The aforementioned 7.2 Gbps speed is achieved at the specified 1.1 Volts of power, meaning that Samsung's implementation is very efficient. According to some estimations made by the company, the DDR5 crossover for the mainstream market is not expected before 2023/2024, meaning that there is still a lot of time for memory makers to refine their DDR5 products.

(and then someone will find a way to mine bitcoins via system ram...)
512 GB is a large capacity, what it can really serve for is RAM Disk, thus making obsolete any PCIe 4 and PCIe 5 SSDs.
DDR4-3200 runs at 1600 MHz double data rate.
;)
a threadripper with 4TB of ram isn't gunna be there to win benchmarks, it's gunna be doing some high capacity shite, with reliability being key
DDR5 for the consumers will be DDR5-4800 running at 2400 MHz double data rate, later upgraded to DDR5-5400, DDR5-6400, etc.
Beside that, 7200 MT/s isn't extremely low. I have my doubts about Alder Lake's ability to handle that and not turn into a puddle of silicon even in Gear 2, let alone Gear 1.
In case you've been confused by the general MT/s versus MHz confusion: just avoid the MHz.
Um, when would you use 4 or 8? It's always 2 for double data rate transfers, and you too divided by 2 in your examples of DDR4 and DDR5 above.
GDDR6 is by 8.
GDDR6X is by 16.
Only the OS though. Programs would be on disk.
Intel Optane and NVMe ain't got nothing on DDR4 / DDR5 speeds! If you can afford 4TB of RAM to accelerate your 4TB database, you're gonna get 4TB of RAM.
100+ fps on modded minecraft.
Praise the blocky lord.
Good, cause it will be useless for gaming couple yrs yet.
