HUGE Nvidia GeForce RTX GPU Prototype Pictured

More images of a recently discovered Nvidia GPU prototype have appeared online. This HUGE 4-slot RTX GPU was discovered by This_Explanation_514, who claims to have found it in a “junk computer bin.” Sadly, this GPU appears to be non-functional. However, there is a chance that Nvidia will use this heatsink design with future GeForce RTX graphics cards. Could this prototype be the basis of the RTX 5090’s heatsink?

The images above and below come from a post on the Nvidia Subreddit. Moderators previously deleted this post, but it has reemerged today for unknown reasons. These images reveal a 4-slot graphics card design that uses a 16-pin 12V-2×6 power connector. This Nvidia prototype appears to be for Nvidia’s unreleased RTX 4090 Ti graphics card.

This Nvidia Prototype is crazy

Below, we can see that this new GPU from Nvidia uses an unusual PCB design. Its primary PCB is angled and sits at the base of the GPU. It runs at a right angle to the GPU’s primary PCIe slot. This design allows air to flow through this GPU’s heatsink unobstructed. Rumour has it that this heatsink is designed for 600W graphics cards. As such, this heatsink design could be utilised for Nvidia’s upcoming RTX 5090 GPU. However, it should be noted that this prototype was reportedly for Nvidia’s previously planned RTX 4090 Ti.

Note that this is the largest Nvidia Founders Edition heatsink that has ever been uncovered. This suggests that Nvidia plans to develop GPUs with TDPs higher than their RTX 4090 and that these plans were in advanced stages. However, it remains to be seen if Nvidia plans to use this heatsink for its future GPUs. After all, Nvidia could opt for a new design scheme for their RTX 50 series Founders Edition heatsinks.
