What’s going on
A version of the RTX 5090 with 128 GB VRAM has been spotted online, tagged at around $13,200. The card is said to be built for AI workloads, not gaming rigs. Right now, most experts think it’s a prototype or a factory-level mod, not an official NVIDIA product.
Why it seems odd
The stock RTX 5090 ships with 32 GB GDDR7. To reach 128 GB, you’d need memory chips that don’t actually exist in that density yet. Engineers looking at the leak say this could only be possible with custom dual-sided PCBs and firmware hacks—something you won’t see in a retail card anytime soon.
Tech site reactions
- Wccftech calls it a “super limited” prototype card.
- Tom’s Hardware describes it as a non-standard design, not built by NVIDIA.
- TechSpot goes further, saying it feels more like a collector’s experiment than a commercial GPU.
Community reactions
- “128 GB VRAM sounds wild. Way more than any gamer will ever need, but it makes sense if someone is pushing huge AI models.”
- “Thirteen grand for a GPU? At that point it’s not even for us. It’s basically a lab toy.”
- “Could be real, could be a mod. Either way, not something regular users will see in their setups.”
My opinion
If you are into AI work this kind of card feels like a game changer. But the price is just crazy. NVIDIA should think about giving more VRAM in normal models at a fair price. If smaller cards had bigger memory, more people could train and test models locally. That would help the whole community. Right now it looks like NVIDIA is holding back. They should learn from this experiment and make higher VRAM standard in the future.
Is the RTX 5090 128 GB VRAM real or just a rumor?
Reports of the RTX 5090 carrying 128 GB of VRAM are most likely pointing to a prototype or a third-party mod, not an official card. The price being shared, around 13,200 dollars, comes from resellers and does not reflect an NVIDIA MSRP. Current memory chips are not large enough to make 128 GB practical on a single card, which makes the claim even harder to believe. Until NVIDIA itself makes an announcement, this version of the 5090 should be treated as a rumor and nothing more.
