New RTX 5090 Ti hints at minor spec bump with a notable increase in power consumption

Murmurs about a high-end Nvidia GPU launching in late 2026 started emerging a few weeks ago, shortly after another report stated the exact opposite. It is said to be a more powerful version of the RTX 5090—an RTX 5090 Ti, even. Moore’s Law is Dead has now learned new information about the mystery new GPU. The graphics card has been in testing since mid-2025.

Tom’s source says the Blackwell Titan has 5% more CUDA cores than the RTX 5090. That would put it at 22,848 CUDA cores, effectively confirming that the graphics card still does not use a full AD202 die with 24,064 cores. As expected, it guzzles a lot of power, with some unlocked prototypes consuming well over 1,000 Watts. However, the 700-750 Watts range is what it will operate at under normal conditions. As a result, the card requires a lot of cooling and needs to be held with both hands.

The massive increase in power consumption, unfortunately, yields only a modest performance improvement, with the RTX 5090 Ti/ Blackwell Titan offering a mere 10% boost over the RTX 5090. Tom’s source says the figure could reach 20% under ideal conditions. Either way, the GPU is presumably meant for hardcore enthusiasts who want to remain on the bleeding edge, and not for the average gamer.

So far, there’s no confirmation about how much VRAM the RTX 5090 Ti/ Blackwell Titan will launch with. Anything over 32 GB is overkill for gaming, but many AI workloads could benefit from 48 GB, and Nvidia could very well position it as a gaming-AI hybrid pro-sumer offering. As far as its price is concerned, anything below $ 2,500-3,000 seems extremely implausible given current market conditions.

That said, the existence of a prototype doesn’t necessarily translate into a launch, as the last-gen Titan Ada prototype never saw a commercial launch. Tom opines that the RTX 5090 Ti/ Blackwell Titan could be Nvidia’s stopgap solution, sitting atop benchmark charts until the RTX 60 series surfaces in 2028.
