Nvidia RTX 4090 vs. RTX 4080 12 GB: Key Differences
The Nvidia RTX 4090 and RTX 4080 are two of the most popular graphics cards on the market. Both of these cards offer great performance and features. However, there are some differences between them that could make one more suitable for your needs than the other.
Let’s look at some of the key differences between them.
Price
The Nvidia RTX 4090 comes with a hefty price tag. The starting price of the RTX 4090 is $1,599, while the RTX 4080 12GB is $899. The price difference between the Nvidia RTX 4090 and RTX 4080 12GB is around $700. If you need a powerful graphics card that costs less than $1,000, then the RTX 4080 12GB may be ideal for you.
Memory
When it comes to memory, the Nvidia RTX 4090 has the edge. The RTX 4090 comes with 24GB of VRAM, while the RTX 4080 has 12GB. This means that the RTX 4090 will be able to handle more demanding games and applications than the RTX 4080.
In terms of raw performance, the RTX 4090 is approximately twice as powerful as the RTX 4080. This extra memory can be helpful for gamers who want to play at high resolutions or who want to enable advanced graphics features like anti-aliasing.
GPU Clock
The RTX 4090 has a base clock of 2235MHz and a boost clock of 2520MHz. The RTX 4080 12GB has a base clock of 2310MHz and a boost clock of 2610MHz. The higher boost clock speed of the RTX 4080 12GB gives it a slight edge over the RTX 4090 in terms of speed.
CUDA Cores
When it comes to raw power, the Nvidia RTX 4090 is in a class of its own. With 16384 CUDA cores, it is one of the most powerful consumer graphics cards on the market. The RTX 4080 12GB, by comparison, has just 7680 CUDA cores. That’s a difference of almost 50%.
The extra CUDA cores give the RTX 4090 a significant performance advantage over the RTX 4080. This difference is highly noticeable when you are playing a graphically demanding game.

The Nvidia RTX 4080 and 4090 are both top-tier graphics cards, but the 4090 wins out for gamers looking for fast speeds and better performance.
