Samsung believes that the JEDEC standard for future DDR6 memory will reach 12800Mbps, the frequency of the overclocking bar may reach 17000Mbps, and may even exceed 20000Mbps. At present, the DDR6 standard is still under discussion, and it is expected to be completed in 2024. Compared with the current DDR5, the number of channels of each module DDR6 memory doubled again, becoming 16bit*4, and the number of banks increased to a maximum of 64.
In terms of video memory, Samsung has revealed a faster GDDR6+ plan to replace the existing GDDR6. Samsung plans to start trial production of GDDR6+ with 1znm this month. Its frequency can reach 24Gbps, and it will become the next-generation GPU configuration. If this frequency can be achieved, the video memory bandwidth of a graphics card with a 320/352/384bit video memory bit width can exceed 1TB/s, and the bandwidth of a 256bit GPU can reach 768GB/s.
As for the new generation of GDDR7 memory, it is expected to provide up to 32Gbps transmission speed and will support real-time error protection technology, but Samsung did not elaborate on it. As for HBM3 memory, Samsung plans to start production in the second quarter of 2022 and said that the speed will be 800GB/s, which will be used in future HPC and data center GPU/CPU systems.
