An unreleased RTX 4090 prototype has been disassembled – the massive four-slot GPU has a unique PCB design and works great

We’ve previously covered the alleged RTX 4090 Ti prototype The Internet has circulated, and finally someone has tested and disassembled everything. Nexus players Testing and teardown took place, with the GPU prototype finally revealed as an RTX 4090 with a massive flow-through heatsink and three fans. Another unique thing about this GPU is that its PCB is mounted parallel to the motherboard, and it features a metal PCIe connector that plugs directly into a socket on the GPU board.

Steve Burke, host of Gamers Nexus, said it took hours to disassemble the GPU, especially since it’s just a prototype and there’s no manual available on how to disassemble the unit. There were also a lot of different screws he had to get to, requiring him to use several screwdrivers. But once he was able to free the GPU’s PCB from its heatsink, Burke said it was most likely an RTX 4090 graphics card with 24GB of VRAM.

The PCB itself on the RTX 4090 prototype is somewhat similar to other GPUs despite its unique mounting method. What makes it unique is its massive cooling solution, which, according to its tests, made the GPU run about 20 degrees cooler than a standard RTX 4090 FE that consumes the same amount of power. This kind of performance has only previously been seen on water-cooled GPUs, which shows just how effective the three-fan, four-slot flow design Nvidia used in this prototype is.

Aside from the external markings and internal configuration indicating that the GPU is an RTX 4090, its driver also said it was a 4090. This most likely makes it a prototype of the 4090’s heatsink design, unless Nvidia just shipped it with a 4090 driver. Hide his true identity. However, when he tested the actual FPS performance of the prototype on the software, the numbers showed that its performance was about 10% lower than the FPS performance. RTX 4090 FE The Gamers Nexus team was on hand, and it’s on par with the 4090 prototype of the unit that has yet to be improved.

So, after much speculation, we can finally confirm that this GPU is in fact the RTX 4090, and not the RTX 4090 Ti. It’s possible that Nvidia was just using this prototype as a test to see if it could create a heatsink that could handle massive amounts of heat for the RTX 4090 Ti, which we haven’t seen the company release. Just in view of that RTX 50 series launched A few days ago, we probably never would have done that.
