Samsung Electronics has started mass production of its new GDDR7 memories, starting with 28 Gbps modules, and is already distributing samples of faster versions, with 32 Gbps and 36 Gbps, to hardware manufacturers. Este strategic move positions the South Korean company at the forefront of graphics memory technology, generating strong expectations in the components market.
The new memories are awaited with great interest by NVIDIA, which is expected to integrate them into its next graphics card update, the long-awaited GeForce RTX 50 SUPER line. The advancement represents a significant leap in bandwidth, a crucial factor for performance in high-resolution games and artificial intelligence applications that demand intensive data processing.
With a capacity of 3GB per module, the new chips offer a 50% increase in density compared to previous generations. Além of speed, the Samsung has improved energy efficiency by up to 20%, an important development for controlling consumption and temperature in high-performance systems.
Evolution of technical specifications
The new Samsung GDDR7 modules maintain the standard 266 FBGA format, which simplifies integration into existing graphics card designs, accelerating adoption by manufacturers. The 28Gbps speed, which is already in volume production, allows GPUs with 384-bit interfaces to surpass the 1TB/s bandwidth mark, eliminating bottlenecks in extreme usage scenarios.
The transition to 3 GB chips per module is one of the main highlights, as it optimizes space on the PCB (printed circuit board). Essa Higher density reduces the number of components required to achieve high VRAM capacities, enabling more compact and efficient designs. PAM3 signaling technology, which replaces the old NRZ, is responsible for up to 30% faster data transfers without increasing power consumption, a notable advance in semiconductor engineering.
Implications for gaming performance
For gamers, the arrival of GDDR7 means a tangible leap in performance. A card like the RTX 5080 SUPER, equipped with a 256-bit interface and 32 Gbps modules, could increase its bandwidth to 1,024 GB/s. Esse gain is essential for running games at 4K resolution with ray tracing technology activated, providing a more fluid and detailed visual experience.
Intermediate models, such as a future RTX 5070 SUPER, would also benefit greatly, being able to jump to 18 GB of VRAM, compared to the 12 GB of the standard version. Essa extra capacity is essential to support ultra-high-resolution textures in the latest and upcoming games, ensuring that gamers do not need to reduce graphical quality due to memory limitations.
Supply chain challenges
The launch of Samsung occurs at a delicate time for the sector, which is facing a global crisis in the supply of DRAM memories. High demand for artificial intelligence accelerators has put pressure on the supply chain, driving up prices and making it difficult for hardware manufacturers to plan.
This situation could directly impact the launch schedule, including the RTX 50 SUPER line itself, which is speculated to hit the market in the first or second quarter of 2026. NVIDIA, in turn, adopts a cautious stance, still without passing on the final specifications of its new products to strategic partners such as Gigabyte and MSI.
The dependence on validation of critical components, such as the new GDDR7 modules, is a factor that adds uncertainty to the schedule. Fabricantes are waiting for supply to stabilize to define their production and launch strategies. Apesar of the challenges, Samsung continues with its sampling plans, distributing versions of 32 Gbps and 36 Gbps to ensure compatibility and stability in high workload scenarios such as 3D rendering and AI model training.
Advantages of PAM3 technology
PAM3 (Pulse-Amplitude Modulation with 3 levels) signaling technology is one of the pillars of GDDR7 efficiency. By transmitting more data per clock cycle compared to the NRZ (Non-Return-to-Zero) standard of previous generations, it achieves superior performance without requiring more power. Essa efficiency is crucial for developing more powerful systems, from workstations to video game consoles, where thermal management is a constant challenge. Complementary to the Para, the Samsung uses special molding compounds in the chips that reduce thermal resistance by 70%, helping to dissipate heat more effectively and ensuring operational stability even under intense and prolonged use, such as long gaming sessions or rendering complex projects.
Rumors about the RTX 50 SUPER line
Speculation in the hardware sector points to the launch of three main models in the SUPER update: the RTX 5070 SUPER, the RTX 5070 Ti SUPER and the RTX 5080 SUPER. NVIDIA’s strategy appears to be focused on offering significant increases in memory capacity, which can reach a 50% increase in some models, prioritizing this aspect instead of just increasing clock frequencies.
NVIDIA is expected to make an official announcement during CES 2026, one of the biggest technology events in the world. Parceiros from the company are awaiting confirmation of the memory speeds that will be adopted as standard. Evidence suggests that the 28Gbps modules will be the basis for most cards, while the faster 32Gbps and 36Gbps versions would be reserved for the highest performance models and the professional RTX PRO product line.
Optimized VRAM Settings
The higher density of 3GB GDDR7 chips allows for unprecedented flexibility in GPU design. Placas video cards with a 256-bit interface, for example, can now be equipped with 24 GB of VRAM using just eight memory modules, maintaining a compact and efficient design. Para high-end workstations with a 512-bit bus can achieve up to 96 GB of VRAM, an ideal configuration for tasks such as complex scientific simulations and large-scale AI model inference.
Applications in AI and content creation
In addition to gaming, 36Gbps modules are designed to accelerate real-time artificial intelligence workloads. Huge bandwidth allows processing of large data sets with minimal latency, which is critical for machine learning applications. For content creators, the 3GB capacity per chip makes it easy to handle multiple 8K video streams, making the editing process more agile and fluid. Desenvolvedores software companies are already exploring how to integrate these gains into neural upscaling tools and other technologies that rely on fast memory.
