NVIDIA RTX "Blackwell" GPU with 96 GB GDDR7 Memory on 512-Bit Bus Appears
Recent shipping manifests suggest that NVIDIA works on a graphics card with 96 GB of GDDR7 memory. Documents reveal a product utilizing a 512-bit memory bus and a clamshell (memory on both PCB sides) design that combines two 3 GB modules per memory controller. This setup effectively doubles the memory capacity of existing workstation-oriented cards. The product is believed to use the GB202 chip, the only Blackwell desktop GPU with a 512-bit interface. The documents refer to a board labeled PG153, a designation not seen in any of NVIDIA's existing consumer GPUs. This finding points toward a professional or workstation model rather than a gaming product. There is a possibility that it could be part of the RTX 6000 Blackwell or RTX 8000 Blackwell series.
NVIDIA's current top workstation card, the RTX 6000 "Ada," features 48 GB of memory. A move to 96 GB would be a substantial jump, enabling more complex workloads for content creation, data analysis, and AI. This GPU could carry a significantly higher power target than current workstation models. However, professional GPUs often maintain lower clock speeds to keep power consumption within limits that accommodate more stable operation in professional environments. There is no confirmed information regarding the card's official name or final specifications, such as core count or actual clock frequencies. NVIDIA's workstation GPUs have historically provided a higher core count than their gaming counterparts. If the rumored 96 GB GPU follows this pattern, it may surpass even the potential GeForce RTX 5090, which comes with 32 GB of GDDR7. NVIDIA is expected to hold its annual GPU Technology Conference in March. This event is viewed as a likely venue for official announcements. Until then, these details remain unverified.

For example, why not go for a 3D hexagon shape with a central node/pathway and an enclosure with water tubes/nitrogen for cooling?
So backward. :P
But this joker is going to 96GB, so it will not be a card I will use or purchase. For just talking, I would get a couple of 5090s if I needed them for workload for pennies on the dollar in a few years.
@venturi
It's wayyy too expensive though
That said I guess their goal is as much about more density within a system than it is one more powerful GPU so probably plays a big role in part. It does seem like GPU PCB's could play a more prominent part within overall case space and how much it occupies in the not so far off future. It would be good to see some more forward thinking design approaches and innovation is my thoughts on it personally.
