RTX 4090 Super homemade
Nvidia keeps on supercharging its graphics cards. However, there is no super version of the current flagship RTX 4090. The TecLab team has now built one itself - from three different cards.
The guys from TecLab are known for mods and overclocking. In their latest project, they have built the card that Nvidia has so far failed to deliver: the RTX 4090 Super. Rumours about the card were already doing the rounds last year, but the chip giant never released it. Why should it, as the normal RTX 4090 is already out of competition.
However, TecLab is not deterred by this and is building the card itself. The biggest upgrade to the card is the memory, which they use from the RTX 4080 Super. This is 23 Gbps GDDR6X instead of the usual 21 Gbps version on the RTX 4090. The PCB used is that of the RTX 3090 Ti Galax HOF. This is known for its good overclocking capacities thanks to the 28 VRM phases. Rumour has it that it was also used for testing the RTX 4090. TecLab is now proving that this is true with the mod. Otherwise the RTX 4090 chip, the AD103-400-A1, would not run on it.
In the video you can see that the guys put a water block on the Frankenstein card. They then overclock the memory to 26 Gbps. Their RTX 4090 Super achieves a 13 per cent higher score in the 8K Unigine Superposition benchmark than a standard RTX 4090. 16 per cent is possible after overclocking the GPU. With further optimisations, they even achieve 40 per cent more performance.
Although this version of the RTX 4090 will never be available in series production, TecLab shows what you can expect from an RTX 5090. Because it will use even faster memory in the GDDR7 standard. And this can have a huge impact on performance, as the guys have now proven.
From big data to big brother, Cyborgs to Sci-Fi. All aspects of technology and society fascinate me.
