In a recent leak, Samsung has now begun to develop DDR5 successor RAM, namely DDR6.
Samsung is reportedly preparing the latest generation of RAM for the next generation of computers. However, this South Korean company is not preparing DDR5 RAM, but another new generation of RAM.
In a recent leak, it is known that Samsung is currently preparing a line of DDR6 RAM. Yes, this is one of the new standards for the next generation of computers.
Wccftech (21/11) reports that Samsung is still in the early stages of development. They are expected to introduce this RAM no later than 2025.
In terms of performance, DDR6 is said to have higher performance than DDR5. If DDR5 has twice the performance of DDR5 and four times that of DDR4. So, if DDR5 has a JEDEC speed of 12,800 Mbps, then DDR6 can go up to 20,000 Mbps or more.
Samsung also revealed its plans to offer the faster GDDR6+ standard that will replace the existing GDDR6 chip. Currently, Micron is the only one with a design for its GDDR6X standard-ready 21 Gbps+ graphics memory.
GDDR6+ seems to be an improvement over GDDR6 rather than just increasing bandwidth. It says the speed is up to 24 Gbps and will be part of the next generation of GPUs.
This RAM will allow GPUs with a 320/352/384 bit bus layout to achieve bandwidths of over 1 TB/s, while 256-bit GPUs will be able to achieve bandwidths of up to 768 GB/s.
There's also GDDR7 which is currently on the graphics DRAM roadmap and is expected to offer transfer speeds of up to 32 Gbps along with real-time error protection technology.
The GDDR7 memory subsystem in a 256-bit wide bus interface at a transfer rate of 32 Gbps will offer a total bandwidth of 1 TB/s. That's 1.5 TB/s on a 384-bit bus interface and up to 2 TB/s on a 512-bit system. This is a large amount of bandwidth for the GDDR standard.
Lastly, there is also confirmation that Samsung plans to start mass production of its HBM3 memory in Q2 2022. The next generation memory standard will support HPC and data center GPUs/CPUs in the future. SK Hynix has shown off its own HBM3 memory module recently.
