Samsung 24 Gb (3 GB) GDDR7 memory enter mass production, and faster models are coming

Samsung’s 3 GB GDDR7 memory is in mass production, and faster variants are sampling

Samsung has confirmed that it has started mass-producing 24 Gb (3 GB) GDDR7 memory modules, offering customers speeds of 28 Gbps. Furthermore, the company has confirmed that it has started sampling faster 32 Gbps and 36 Gbps modules.

With 3GB of memory per module, these DRAM chips feature 50% more memory than the 2GB GDDR7 chips used in Nvidia’s RTX 50 series desktop graphics cards. This allows GPU manufacturers to create GPUs with increased memory densities. Nvidia already uses these chips with its 24GB RTX 5090 laptop GPU and RTX 6000 PRO desktop GPUs.

Samsung’s new 32 Gbps and 36 Gbps GDDR7 modules are 14.2% and 28.5% faster than today’s 28 Gbps modules, respectively. These are notable increases in memory bandwidth. Rumour has it that these 3GB GDDR7 memory chips will form the basis of Nvidia’s planned RTX 50 SUPER series GPUs. However, these plans have reportedly been delayed considerably due to the global DRAM shortage.

With its newest GDDR7 memory offerings, Samsung is pushing for higher speeds and boosted memory densities. However, Samsung is not the only memory manufacturer to do this. At ISSCC 2026, SK Hynix plans to discuss its 48 Gbps GDDR7 memory modules, which will also feature 3 GB capacities.

While SK Hynix’s planned modules are impressive, Samsung has 36 Gbps memory that is already being sampled with customers. It will be a while before SK Hynix reaches this stage with its 40+ Gbps modules.
