Samsung: the standard frequency of DDR6 memory can reach 12800Mbps, GDDR7 frequency up to 32Gbps

At present, DDR5 has just been listed with Intel’s 12th-generation Core Alder Lake, but Samsung has already stated that they are already developing the next generation of DDR6 memory. At the annual technology day event, Samsung revealed information on next-generation memory technologies such as DDR6, GDDR6+, GDDR7 and HBM3.

Computerbase has obtained various information about the new generation of memory from Samsung. At present, DDR5 is still in the early stage of its life cycle, and the frequency is generally not very high, but the frequency will slowly rise over time. Samsung believes that in the near future the frequency of DDR5 will be increased to the JEDEC standard of 6400Mbps, and the frequency of the overclocking bar can reach 8400Mbps. In fact, some manufacturers have already increased the frequency of DDR5 memory to 7000Mbps.

The next generation of DDR6 is already in the early development stage and will be used to replace DDR5 in the future. Of course, it is expected to be launched at least from 2025 to 2026. DDR4 memory will be used for at least 6 years, and DDR5 to DDR6 is estimated to be about the same time.

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.
