Nvidia’s RTX Blackwell workstation GPU spotted online: A 96GB memory beast

Nvidia appears to be gearing up for the next generation of professional GPUs, with a flagship RTX Blackwell workstation model making waves in shipping manifests. This GPU reportedly packs an eye-popping 96GB of GDDR7 memory, paired with a cutting-edge 512-bit interface, promising a significant leap forward for AI, high-performance computing, and other professional workloads.

Massive memory boost for Blackwell

While Nvidia’s consumer RTX 5000 series has dominated recent headlines, the company’s workstation lineup has been relatively quiet—until now. Leaked shipping details via ComputerBase suggest that the RTX Blackwell workstation GPU is set to deliver nearly double the VRAM of its predecessor, the RTX 6000 “Ada.” With 96GB of GDDR7 memory onboard, Nvidia prioritises high memory capacities to meet the demands of data-intensive workflows.

What’s particularly interesting is the rumoured 512-bit memory interface. Achieving this likely involves a “clamshell” configuration, stacking 3GB GDDR7 modules—a notable jump from the 2GB modules used in the RTX 5090 desktop variant. This approach would give the Blackwell GPU the memory bandwidth and capacity needed for AI training, scientific simulations, and other heavy-duty applications.

New hardware, new possibilities

WccfTech reports the leaks reference a new board design, the PG153, which hasn’t been used in Nvidia’s workstation GPUs before. This aligns with Nvidia’s trend of introducing bespoke hardware for its professional lineup. If true, the RTX Blackwell flagship could offer a staggering upgrade in memory, compute power, and efficiency, building on the RTX 6000 “Ada’s” already impressive specs.

To put this into perspective, the RTX 6000 “Ada” launched with 48GB of GDDR6X memory and a 384-bit bus. Doubling the memory capacity while shifting to GDDR7 could mean even greater throughput, especially for tasks that require massive datasets.

When can we expect it?

While Nvidia hasn’t officially confirmed the RTX Blackwell workstation series, all signs point to an unveiling at GTC 2025, which kicks off in March. Historically, this event has been a stage for Nvidia to highlight its professional GPU advancements, making it the perfect platform to introduce the Blackwell lineup.

If the rumors hold true, this next-gen GPU could set a new benchmark for professional graphics cards, catering to the ever-growing demand for AI and HPC solutions.
