Fast GDDR7 memory is on its way as SK hynix announces its offerings at the NVIDIA GPU Technology Conference 2024. SK hynix has primarily been in the news for the last year or so with announcements regarding its high bandwidth memory (HBM) products but it quietly unveiled GDD7 memory at its booth stating speeds up to 40 Gbps / 160 GB/s with capacities ranging from 16 GB up to 24 GB. However, the press release states it will have a maximum bandwidth of 128 GB/s and use up to 40% less power than previous GDDR6 memory.
Per SK hynix (via newsroom page):
“Visitors to SK hynix’s booth can also check out some never-before-seen products, including the next-generation GDDR7 DRAM specialized for video and graphics processing. Compared to its predecessor GDDR6, the latest GDDR product offers double the maximum bandwidth (128 GB per second), a 40% improvement in power efficiency, and enhanced visuals due to its expanded memory density. Set to be used in graphics cards and GPUs, GDDR7 will be integral for AI and advanced technologies which require rapid and large-capacity data processing.”
Not much else was revealed about the new GDDR7 memory but Hardwareluxx was able to get it confirmed that 2 GB and 3 GB chips would become available to graphics card manufacturers. Even though the booth display card stated speeds up to 40 Gigabits per second it is believed that there will be slower versions available at launch. This aligns with previous news bites regarding early product availability for the new memory.
Recent rumors have suggested that NVIDIA’s top three GPUs in the RTX 50 series lineup will use 28 Gbps GDDR7 but that has yet to be confirmed. Nor has it been confirmed if it will use modules from Sk hynix or Samsung.
