SK Hynix demonstrates 40Gbps ultra-high-speed GDDR7 video memory

According to news from this site on March 21, Samsung demonstrated its upcoming 28Gbps and 32Gbps GDDR7 video memory at the GTC 2024 exhibition, and Hynix went one step further. The company is developing faster video memory modules.

According to HardwareLuxx, Samsung previously claimed to be developing 37Gbps GDDR7 video memory, which is currently the fastest known such memory. Hynix has set its target at a higher 40Gbps, which may become the performance target for its entire G7 series of graphics memories.

This site noticed that the new generation of GDDR7 memory will also provide higher capacity options. The versions displayed this time include 16Gb and 24Gb styles (corresponding to 2GB and 3GB respectively) memory capacity). According to the specifications announced by the JEDEC organization, the speed of GDDR7 memory is expected to be further increased to 48Gbps in the future, and the capacity will also reach 64Gb (8GB), which will bring a huge leap in video memory capacity. A standard 256-bit graphics card interface paired with such memory will provide up to 64GB of graphics memory, which is a huge improvement compared to the current maximum of 16GB.

In addition, SK Hynix also demonstrated DDR5 MCR DIMM memory modules with a transfer rate of up to 8800 MT/s, a capacity of up to 64GB, and a voltage of 1.1V.

Currently, the NVIDIA RTX 50 series graphics cards, which are expected to be launched by the end of the year, will be the first products to use GDDR7 video memory. According to reports, this series of graphics cards will use 28Gbps memory speed, leaving room for speed increases of more than 32Gbps for next-generation products.
