A souped-up NVIDIA GeForce RTX 4090 may never see the light of day officially, and the company has, at current, squashed any notion of such a thing ever happening. Clearly unhappy about this, Brazilian TechTuber gave flipped the green GPU maker the proverbial bird and decided to make its own “Super” variant of the card.
The tech channel built the card from ground up (head’s up, the entire presentation is in Portuguese), using components sourced from a small variety of sources. Let’s be clear here: Teclab is claiming that it did not just take pre-made PCB with GPU on it, but took the time to find an AD102 GPU, like the one found in the RTX 4090, and then sourced the PCB and VRAM from other brands.
Specifically, Teclab says its custom-built GPU was made from parts from a Galax RTX 3090 Ti HOF OC Lab Edition. The end result is the Frankencard – another name endearingly given to its hodge-podge card – with custom GDDR6X memory modules that allow the RTX 4090 Super to achieve speeds of up to 25.8 Gbps. Far higher than the stock 21 Gbps on the current 4090.
And Teclab appears to have the benchmarks and results to back up the RTX 4090 Super; the Frankencard is about 40% faster than the stock GPU, scoring an impressive 17,454 points over the latter’s average 12,479 points on Superposition’s 8K test. It’s worth noting that those performance gains were attained through driver LoD (Level of Detail) adjustments and without the tunings, the gains are only around 16%.
Again, Teclab’s RTX 4090 “Super” is merely just an exercise, and it is improbable that NVIDIA will be releasing such a card, especially not with the launch of the GPU brand’s RTX 50 Series Blackwell cards expected to launch later this year.
