Modders at Teclab have created a custom graphics card named the RTX 4090 Super, outperforming the RTX 4090 by 13% in benchmarks.
While this graphics card is not available for purchase, the innovation behind combining top-notch components showcases significant performance gains. The core of the RTX 4090 Super is the RTX 4090 GPU, utilizing Nvidia’s AD102 die. However, Teclab made extensive modifications to other parts of the graphics card.
By incorporating memory modules from an RTX 4080 Super, which feature faster memory compared to the standard RTX 4090, Teclab was able to achieve speeds of 26 Gbps on the GDDR6X modules, surpassing the stock 21 Gbps modules in the RTX 4090. This upgrade alone resulted in a 13% performance increase without additional overclocking.
Further enhancements included placing the AD102 die on a board from a Galax RTX 3090 Ti HOF OC Lab Edition. This board, equipped with 28 power stages capable of handling high voltages and dual 16-pin connectors for increased power supply to the GPU, along with a premium water block, enabled Teclab to overclock the GPU and optimize performance in benchmarks like Superposition, resulting in a 40% improvement over the stock RTX 4090.

Despite achieving top-tier performance in benchmarks, the custom design of the RTX 4090 Super makes it distinct from the standard RTX 4090, with a new board, custom memory, and only the GPU being linked back to the original model.
While Nvidia did not release an official RTX 4090 Super, the experiment demonstrates the potential for even greater performance. With the upcoming RTX 50-series cards rumored to feature GDDR7 memory, which promises a significant performance boost in games, Teclab’s RTX 4090 Super highlights the impact of memory speed on overall performance.
