Samsung 24Gb GDDR7 Enters Mass Production

According to industry reports, Samsung has officially moved its 24Gb GDDR7 memory into mass production after announcing the technology in October this year. The first production version runs at 28Gbps, while faster 32Gbps and 36Gbps variants have already entered the sampling stage, according to Samsung's website.

According to Samsung's product information, the currently mass-produced 3GB GDDR7 chip operates at 28Gbps and is expected to be used in most models within NVIDIA's upcoming GeForce RTX 50 series (with the likely exception of the RTX 5080). At the same time, Samsung has two higher-speed 3GB versions labeled at 32Gbps and 36Gbps, which are now being evaluated by partners through early samples.

According to NVIDIA's official teaser video, the RTX 5090 Founders Edition features a GDDR7 chip marked “K4vcf325zc-sc28”, matching Samsung's 28Gbps model number. The two faster chips are listed as “K4vcf325zc-sc32” and “K4vcf325zc-sc36”, confirming that the higher-speed versions are real and already prepared for future deployment.

According to current roadmaps, Samsung is also developing higher-capacity GDDR7 memory, which is widely expected to support NVIDIA's RTX 50 Super series. However, with DRAM prices rising sharply, industry watchers believe the launch of the RTX 50 Super line could slip to Q3 2026.

According to early performance expectations, it is still unclear whether NVIDIA will adopt the 32Gbps or 36Gbps chips in the Super lineup. Even if it sticks with the 28Gbps version, GDDR7 is set to deliver a major boost in bandwidth and efficiency. One confirmed upgrade is the upcoming GeForce RTX 5070 Super, which is expected to ship with 18GB of memory, up from 12GB on the standard RTX 5070—an upgrade that should bring noticeable gains for gaming and content creation.
