The decision between the two latest graphics cards from Nvidia, the Nvidia GeForce RTX 4090 and RTX 4080, can be a challenging one. Both have advanced Ada Lovelace architecture, DLSS 3 technology, and massive cooling fans.


However, delve into the details, and the discrepancies appear that can affect your decision. This article will cover all the aspects of these graphics cards, such as price, performance, and availability.

Nvidia GeForce RTX 4090 vs. RTX 4080: A Detailed Showdown for Gamers

Performance: RTX 4090 is the King, But it Also Faces the Problem of CPU Bottlenecking

The RTX 4090 is a real monster delivering whatever ray-tracing, rendering, and high-refresh-rate 4K gaming you throw at it. It doesn’t stop there, setting the bar higher for the RTX 4080.

The primary distinction is VRAM. RTX 4090 stands out with its 24GB against RTX 4080’s 16GB. The majority of gamers will be satisfied with 16GB, but content creators will love the extra space for high-resolution video editing.

Result tables clearly illustrate the game lead of RTX 4090 at a 4K resolution. In games like Call of Duty: In Modern Warfare 2, the RTX 4090 easily manages 34fps at 4k resolution. This is particularly obvious for gamers with high refresh-rate 4K monitors.

CPU Bottleneck

Regardless, RTX 4090’s extraordinary performance can uncover the CPU’s weaknesses. Some games at 1440p resolution are CPU-limited, i.e., they become less effective as far as the CPU is concerned.

The true power of the RTX 4090 can only be realized when it is combined with a top-notch CPU like the Intel Core i9-13900K or AMD Ryzen 9 7950X.

Both GPUs take advantage of Nvidia’s game-changing and powerful DLSS 3 technology, particularly its Frame Generation function.

This, in turn, increases the performance in the supported games such as Flight Simulator 2020. The RTX 4090 with its well-equipped hardware outperforms in the DLSS area, giving to the fact that the latter is pushed even further.


When it comes to ray tracing benchmarks, the RTX 4090 blows the rest of the pack away. For example, in Cyberpunk 2077 with ray tracing enabled at 4K, the RTX 4090 gives a much smoother performance (83. 36fps (GeForce RTX 3060) vs 53. 9 fps (GeForce RTX 4080).

Both GPUs represent an excellent choice for content creators in terms of performance. The RTX 4080 might be the best choice for you if you have a certain workflow.

On the other hand, for video editing professionals dealing with high-resolution videos, RTX 4090 with 24GB of VRAM could be a breakthrough.

Although the RTX 4090 and the RTX 4080 did very well, they are not known for their power efficiency. The RTX 4090 possesses a TDP of 450W, whereas the RTX 4080 stands at 320W.


On the other hand, despite being less efficient, their newer successors provide more performance along with the same power usage.

The RTX 4090’s 12VHPWR adapter has been in the news because of the melting issue. On the bright side, the root cause was mainly user error resulting from incorrect connection of the devices. Confirm a reliable connection and discard excessive cable bending that leads to issues.

Both GPUs have superior cooling systems, which means they are very quiet. Nevertheless, some units may cause coil whine.

Price and Availability: The RTX 4090 Model Seems to be Taking the Lead in Something Other than Technological Advancement

The RTX 4090 on the paper seems to be priced slightly over $1599 whereas the MSRP for RTX 4080 is $1199. Nevertheless, the real-life scenario tells a different story.


Though the year 2024 witnessed an upsurge in GPU availability, the RTX 4090 is still out of reach for many.

No candy is as rare as this one; hence, its street price on the secondary market is the highest – and it is the first to go out of stock.

On the other hand, the RTX 4080 is easier to get. But its price tag remains a controversial issue as it does not offer good value considering its barely noticeable performance improvements over the previous generation.

This implies that it is RTX 4090, costing as much as it does, which is more appealing, with its better performance-to-cost ratio (this looks strange as well).


Nvidia GeForce RTX 4090 vs RTX 4080: Table of Differences

AspectNvidia GeForce RTX 4090Nvidia Geforce RTX 4080
PerformanceSuperior performance in gaming and content creationSlightly lower performance compared to RTX 4090

Cooling SystemEffective cooling system, some units may have coil whineEffective cooling system, some units may have coil whine
Value for GamersHigh performance, but high price and limited availabilityGood performance, but price might not justify the upgrade
Value for Content CreatorsExcellent, especially for high-resolution video editingGood, 16GB VRAM might suffice for most workflows
Price (MSRP)
AvailabilityLimited availability, often sold out; high street pricesMore readily available, closer to MSRP

Considering your needs and preferences, here’s a summary of which GPU might be more suitable for you:

Get the RTX 4090 if:

  • You prioritize bleeding-edge performance and can find one in stock.
  • You’re a content creator who needs the extra VRAM for high-resolution video editing.
  • You’re willing to pay a premium for the top-tier performance.

Get the RTX 4080 if:

  • Availability is a major concern, and you can find one at or close to MSRP.
  • You prioritize value over absolute top performance.
  • You’re a content creator who can work with 16GB of VRAM effectively.

Wrapping It All: RTX 4090 takes the early lead on performance, while availability becomes an obstacle on the way.

The expensive price of the RTX 4080 makes the RTX 4090 a better option even though its cost is also very high.

  • You have a budget for a large GPU and have also managed to find one in stock.
  • You focus on top performance for the most demanding tasks, which include high-refresh-rate 4K gaming and other activities.
  • You are a content creator who requires the additional space of 24GB of VRAM.
  • Accessibility is an issue equally as MSRP is available.
  • You lead by value rather than seeking out the absolute highest performance.
  • You’re a content creator who will be able to take advantage of 16GB of VRAM and its overall excellent performance.

Finally, the RTX 4090 will be the king of performance, but because of its limited availability, it might not be an easy decision. The RTX 4080 provides a great performance package for a range of content creators.

Yet, its pricing is too steep for many gamers. Think about your needs, budget, and the extent to which you are willing to hunt for a GPU before you make your final choice.

Additional Tips:

  • Monitor retailer stock and price alerts regarding both GPUs simultaneously.
  • Take used graphics card markets as an example, yet do it cautiously and make sure you have some good warranty coverage.
  • Assess your current system. However, if your CPU limits the 4090 RTX’s performance, you may need to upgrade the CPU.

Let’s hope that this thorough comparison will serve you as a compass while navigating the Nvidia GeForce RTX 4090 and 4080. Through thoughtful analysis of your requirements and the state of the market, you will be on the right track to achieving the next level of graphical realism.
