One of the key differences between the Nvidia RTX 4090 and RTX 4080 16GB is their total graphics power. Nvidia RTX 4090 has a TGP (Total Graphics Power) of 450 Watts, while the RTX 4080 16GB has a TGP of 320 Watts. 

However, the recommended power supply unit for the RTX 4090 is 850 Watts, while the recommended power supply unit for RTX 4080 16GB is 750 Watts. 

If you’re looking for a graphics card that is very powerful but consumes less power, then the RTX 4080 16GB is your best option. 

CUDA Cores

The RTX 4080 16GB has 9,728 CUDA cores, and the RTX 4090 has 16,384 CUDA cores. Clearly, the RTX 4090 has more of them. This gives it an advantage over the GeForce RTX 4080 16GB. These additional cores allow for better performance when using complex software or games. 


The RTX 4090 comes with a price tag of $1,599; $400 more than the RTX 4080 16GB, which costs $1,199. If you’re looking for a powerful graphics card that costs less than $1,500, then the RTX 4080 16GB is ideal for you.


Nvidia RTX 4080 16GB and RTX 4090 are based on the Ada Lovelace architecture and offer significant performance improvements over the previous-generation cards.  However, the RTX 4090 offers marginally better results than the RTX 4080 16GB when it comes to general gaming use cases. The Nvidia RTX 4080 16GB is slightly slower than the Nvidia RTX 4090 but is still capable of delivering great performance.
