Micron revealed that its next-generation GDDR7 memory for future GPUs will be available in the first half of 2024. Micron revealed its current development on numerous DRAM and memory products, including the future GDDR7 memory for graphics, at its Q3 2023 Earnings Call. The business revealed that they are working on next-generation GDDR7 memory, which will be ready in the first half of 2024, or next year.
According to Micron, the GDDR7 memory will be based on the 1ß process node, which will be replaced by the 1 process node in 2025, according to the production timetable.
The EUV node will be built first in Micron’s Taiwan plant, where the EUV capability is already in place, and then at the Hiroshima, Japan fab. Based on earlier information, we know that the GDDR7 memory has already entered the verification stage, with Cadeance providing the first solutions to consumers.
The GDDR7 memory solution will succeed in GDDR6 and GDDR6X solutions that have yet to reach their full potential. The new standard will allow PAM3 signalling as well as much faster pin rates of up to 36 Gbps.
NVIDIA’s GeForce RTX 40 series graphics cards now employ the fastest memory option, the GDDR6X memory solution, which enables up to 22 Gbps pin rates, while AMD’s Radeon RX 7000 series cards use the conventional 20 Gbps GDDR6 solution.
There’s still a lot to be squeezed out of the GDDR6 generation, as Samsung is already working on its GDDR6W design and GDDR7 solutions, which should quadruple the capacity and performance, and Micron is likely to push GDDR6X to even greater speeds in the future. The business has been mass-producing 24 Gbps dies, although none have been used by a consumer-grade GPU.
Given that NVIDIA’s Ada Lovelace-Next GPUs aren’t scheduled until 2025, AMD will most likely be the first to use Micron’s GDDR7 memory dies. Meanwhile, NVIDIA is one of Micron’s largest AI and datacenter customers, delivering HBM3 chips for the DGX GH200 supercluster and the remainder of the Hopper processors.
