Nvidia RTX 5090 Ti/ Titan Blackwell GPU specifications leak

Nvidia’s reportedly building a new RTX Blackwell flagship

According to a report from Moore’s Law is Dead, Nvidia has been working on a new flagship-level RTX 50 Blackwell GPU since H1 2025. Currently, it is unknown what the GPU will be marketed as, though RTX 5090 Ti or RTX Titan Blackwell branding seems likely. Early specifications for this “RTX 5090 Ti” GPU give it around 5% more CUDA cores than Nvidia’s RTX 5090 and a much higher power limit.

Allegedly, this new GPU’s “standard” TDP was 700-750W, with prototypes hitting TDPs of 1000W+. The GPU was reportedly around 10% faster than an RTX 5090 at the time of testing. Prototype models were large and heavy enough to require two hands to hold. In other words, this is a big and power-hungry graphics card.

Final performance for Nvidia’s alleged Blackwell flagship could reportedly exceed that of high-power RTX 5090 models like the MSI Lightning Z and ASUS ROG Matrix. This is thanks to the addition of extra CUDA cores, potential increases in memory speed, and aggressive GPU chip binning. These factors combined could reportedly allow Nvidia to deliver a 15-20% performance boost over Nvidia’s stock RTX 5090.

Prior rumours have alleged that Nvidia plans to release a “very high-end RTX 50 series” GPU in Q3 2026. With Nvidia’s RTX 5090 already unaffordable for most gamers, it is crazy to think the company could be building something higher-end. That said, ASUS’ ROG RTX 5090 Matrix and MSI’s RTX 5090 Lightning Z sold out almost immediately. Clearly, there is a market for ultra-uber graphics cards. However, even if this planned GPU is real, Nvidia could cancel the project ahead of launch. After all, Nvidia didn’t release its TITAN Ada.
