Samsung’s GDDR7 2836 Gbps parts move through production
Samsung Electronics’ GDDR7 DRAM has received a presidential commendation at the 2025 Korea Tech Festival in Seoul, recognizing the company’s 12-nm-class GDDR7 device with 24 Gb capacity and a data rate of 40 Gbps. The award, granted by Korea’s Ministry of Trade, Industry and Resources, highlights Samsung’s graphics and AI-focused DRAM at a time when demand for AI inferencing hardware is climbing.
Market researchers expect GDDR7 demand to spike as new chips adopt the standard, including NVIDIA’s RTX gaming GPUs and Rubin CPX, an inference GPU that will ship with 128 GB of GDDR7. According to analysts, NVIDIA has asked Samsung to raise GDDR7 supply, and the company plans to more than double output at its Pyeongtaek DRAM line.

Samsung’s own catalog shows how the GDDR7 lineup is shaping up. The company lists three 24 Gb variants : K4VCF325ZC-SC28 at 28 Gbps in mass production, plus K4VCF325ZC-SC32 and K4VCF325ZC-SC36 at 32 and 36 Gbps , both currently in the “sample” stage.
Alongside those parts, Samsung also offers 16 Gb GDDR7 chips. The K4VAF325ZC-SC28 and K4VAF325ZC-SC32 devices provide 28 and 32 Gbps speeds respectively, organized as 512M x 32 and listed as mass-production products on Samsung’s site.
As we have always said regarding these 30 Gbps+ GDDR7 memory announcements, they are unlikely to appear with current-gen GPUs (Blackwell) and the refresh. Rather, these are to be expected with RTX 60, possibly with next-gen Radeon GPUs, although AMD seems to lag behind NVIDIA in this specific hardware update.
