Samsung Samples Record-Breaking 36 Gbps GDDR7 Memory for Next-Gen Graphics Cards
Samsung has begun sampling its fastest GDDR7 memory to date, achieving speeds of 36 Gbps. Each chip offers a 24 Gb capacity, equating to 3 GB per module—an important milestone for the upcoming generation of graphics cards. This development positions Samsung at the forefront of high-performance graphics memory, catering to the increasing demands of modern GPUs.
Mass Production of 28 Gbps 3 GB GDDR7 Modules
In addition to the 36 Gbps variant, Samsung is also manufacturing 28 Gbps 3 GB GDDR7 modules, which have already entered mass production. These modules are expected to be integrated into NVIDIA’s next-generation mid-cycle SUPER refresh graphics cards. The confirmation of 3 GB modules in mass production is significant, as such configurations have been rare in the market. The introduction of 28 Gbps modules provides a welcome boost to VRAM speeds for mainstream and enthusiast GPUs.
32 Gbps GDDR7 Modules and Professional GPU Applications
Samsung is also sampling 32 Gbps 3 GB GDDR7 modules, targeting a balance between performance and efficiency. However, it is anticipated that most manufacturers will initially adopt the 28 Gbps modules for broader market compatibility. The higher-speed 32 Gbps and 36 Gbps modules are likely to be reserved for professional-grade graphics cards, such as NVIDIA’s Pro-Viz series.
NVIDIA’s RTX PRO 6000 “Blackwell” GPU already incorporates these 3 GB GDDR7 modules. Additionally, the RTX PRO 5000 “Blackwell” GPU has been updated to feature 72 GB of GDDR7 ECC memory, up from 48 GB. This upgrade utilizes 24 modules, each with a 3 GB capacity, to achieve the expanded memory total. Such advancements are crucial for professional workloads that require high memory bandwidth and capacity.
Implications for NVIDIA’s Upcoming SUPER Series
Despite these advancements, NVIDIA has yet to provide add-in card (AIC) partners with final specifications for the upcoming RTX 50 SUPER series. As of November, no AIC has received detailed design information, indicating that NVIDIA may be waiting for the finalized selection of GDDR7 modules before proceeding. The company’s mid-lifecycle refresh is reportedly scheduled for late Q1 to early Q2 2026, with a possible announcement at CES 2026.
Industry speculation suggests that three new SKUs—the RTX 5070 SUPER, RTX 5070 Ti SUPER, and RTX 5080 SUPER—will replace existing models. The primary upgrade is expected to be increased memory capacity, with each card anticipated to offer 50% more memory than its non-SUPER counterpart. This enhancement will be particularly beneficial for users running demanding applications and games that require greater VRAM resources.
Samsung’s advancements in GDDR7 memory technology are set to play a pivotal role in shaping the next generation of graphics cards, delivering higher speeds and larger capacities to meet the evolving needs of both professional and consumer markets.
