NVIDIA’s GeForce RTX 4090 Ti GPU has once again surfaced online, this time in the form of an intriguing IO bracket from the unreleased high-end model.
Anticipation was high prior to the launch of the NVIDIA GeForce RTX 40 “Ada” GPU lineup. Enthusiasts and insiders buzzed with excitement about a flagship graphics card destined to redefine performance standards—the GeForce RTX 4090 Ti. Despite the fervor, this graphics card ultimately never saw the light of day, remaining an elusive piece in NVIDIA’s history.
The GeForce RTX 4090 Ti was expected to utilize the full AD102 GPU, finely tuned for top-tier performance with an impressive power rating. Early prototypes hinted at a quad-slot cooling solution, although this concept was mainly for testing purposes. Both RTX 4090 and 4090 Ti reportedly underwent trials with unconventional cooling and PCB designs. While these innovative solutions didn’t materialize for the market, there’s a chance these ideas might resurface in the upcoming RTX 50 series.
Recently, a fascinating discovery was made by @Harukaze5719, who found a listing on Chinese marketplace Taobao. The listing showcased an IO bracket, allegedly for the unreleased GeForce RTX 4090 Ti. The bracket, labeled “GeForce RTX 4090 Ti” and bearing the model number “PG136F,” is a tantalizing glimpse of what could have been.
Interestingly, contrary to rumors, the IO bracket suggests the RTX 4090 Ti would have adhered to a 3-slot cooling solution similar to the RTX 4090 and 4080. This bracket features a large exhaust vent and cutouts for four display outputs—one HDMI and three DP 1.4—mirroring its high-end counterparts.
The seller on Taobao indicated that the RTX 4090 Ti was intended to feature a staggering 48 GB of GDDR6X VRAM. However, according to MegaSizeGPU, the card’s specifications were never cemented, leading to its cancellation, allegedly due to new US regulations.
In the words of MEGAsizeGPU (@Zed__Wang), it’s believed that the final specifications never reached completion, and had it been finalized, it was highly probable to feature 24GB of VRAM instead.
Ultimately, the RTX 4090 Ti remains a tantalizing ‘what-if’ in the GPU world—a powerhouse that was planned but never reached gamers’ hands. While its exact capabilities remain a mystery, it will go down as one of the potential game-changers that stayed behind closed doors, likely for compelling reasons.
