Samsung’s 40 Gbps GDDR7 Memory Earns Presidential Recognition at Korea Tech Festival 2025
At the 2025 Korea Tech Festival in Seoul, Samsung’s latest innovation in memory technology took center stage. The company’s 40 Gbps GDDR7 memory chip, built on a cutting-edge 12 nm (10 nm class) DRAM node, was honored with a prestigious presidential recognition medal. This next-generation memory module features a 3 GB (24 Gb) capacity and is engineered to deliver exceptional performance for future graphics cards and high-performance computing applications.
Breakthroughs in GDDR7 Memory Performance
Samsung’s announcement follows closely on the heels of its recent sampling of GDDR7 memory running at 36 Gbps, which already set new benchmarks for speed. The 3 GB capacity per chip is designed to meet the increasing demands of next-generation GPUs, offering a significant leap in memory bandwidth and efficiency. In addition to the 40 Gbps variant, Samsung is also mass-producing 28 Gbps 3 GB modules, which are expected to be integrated into NVIDIA’s upcoming mid-cycle SUPER refresh of the GeForce RTX 50-series GPUs.
The introduction of 3 GB GDDR7 modules is particularly noteworthy, as such capacities are relatively rare in the current market. The confirmation of mass production at 28 Gbps provides GPU manufacturers with faster VRAM options, supporting the development of more powerful and efficient graphics solutions. As Samsung continues to test its 40 Gbps GDDR7 modules, industry observers are keen to see which products will leverage this advanced memory technology.
Industry Competition and the Future of High-Speed DRAM
The race to deliver faster and more efficient memory is intensifying. SK Hynix, one of Samsung’s main competitors, is preparing to unveil its own advancements at ISSCC 2026. The company plans to showcase a 24 Gb GDDR7 chip rated for an impressive 48 Gbps. This module features a symmetric dual-channel design and enhanced internal interfaces, pushing GDDR7 speeds well beyond the previously anticipated 32 to 37 Gbps range.
The new SK Hynix chip offers a per-pin data rate that is over 70% higher than current 28 Gbps modules, increasing per-chip bandwidth from 112 GB/s to 192 GB/s. This rapid progress in GDDR7 technology reflects the growing industry demand for higher bandwidth on 3 GB chip modules, especially as applications in gaming, AI, and data-intensive workloads continue to expand.
Meeting the Demand for Next-Generation Graphics Memory
As the graphics and computing industries push for greater performance, memory manufacturers like Samsung and SK Hynix are accelerating the development and production of high-speed GDDR7 modules. The move toward 3 GB modules operating at speeds up to 40 Gbps and beyond is set to redefine the capabilities of future GPUs and high-performance systems. With mass production underway and new innovations on the horizon, the next generation of graphics memory is poised to deliver unprecedented bandwidth and efficiency.
