Being the highest-end card available on the consumer market, the RTX 4090 was launched with a huge price tag. Supply shortages and scalpers have forced the price of this card to go even further beyond this. The price tag of the RTX 4080 Super is also abysmal, but it seems like a bargain compared to the RTX 4090.


RTX 4090: If you are seeking the best performance, the RTX 4090 is unrivalled as the top-performing consumer graphics card. However, be prepared for a necessary power supply upgrade and ensure a high-end CPU to avoid bottlenecking this powerhouse.

RTX 4080 Super: While the RTX 4080 Super doesn’t provide a substantial upgrade over the RTX 4080, its price reduction to $1199 and a slight performance boost make it a reasonable choice for high-end 4k gaming. Although not capable of maxing out settings in the most demanding games, it delivers a satisfying gaming experience.

To conclude, the decision between the RTX 4080 Super vs RTX 4090 is between luxury and ultra-luxury. For the few people who can afford the RTX 4090, nothing else is quite like it on the planet. However, if you feel the need to balance out your system’s price-to-performance ratio, the RTX 4080 Super does the trick.
