Here’s a homemade RTX 4090 Super since Nvidia won’t make one

We have RTX 4090 Super at home.

While Nvidia clearly had plans to launch an RTX 4090 Super, Ti, or Titan, we’ll likely never see either officially materialise. There is still time for Team Green to change its mind, but a group of enthusiasts have taken matters into their own hands for now. Forging a fantastic Frankenstein graphics card, composed of RTX 4090 and 3090 Ti parts, its performance is much easier on the eyes than its physical appearance.

As much as GeForce RTX 4090 remains the best graphics card on the market, Nvidia still has some horsepower left on the table. After all, the company’s flagship uses a cutdown version of its AD102 GPU, leaving an 11% shortfall in most specs compared to the full die. While we sadly don’t see that in action with this make shift RTX 4090 Super, the team behind its creation have found other ways to give it a boost.

Teclab, a team of Brazilian overclockers, has dared to make the dreams of RTX 4090 Super a reality. Well, sort of. It still uses the same AD102-300 GPU as found in RTX 4090 but it’s been turbocharged with GDDR6X memory running at 26Gbps. It also doesn’t use the enormous heatsink that leaked a while back, with a watercooled block taking its place.

With a few extra tweaks to strap settings, BIOS, and voltage, the would-be GeForce RTX 4090 Super comes to life. The difference in performance between it and a stock card can be as much as 40% according to Teclab’s benchmark results using Unigine Superposition 8K. While such exceptional results are with both GPU and memory overclocks, there’s no way a vanilla RTX 4090 would be able to perform as well.
