With the new generation of flagship graphics cards from Nvidia and AMD made available to the public, the competition is once again heating up. The newly released AMD Radeon RX 7900 XTX and the Nvidia RTX 4090 are fighting it out to take home the crown of the best graphics card for PC.
Both of these graphics cards are loaded to the brim with cutting-edge performance and industry-leading features. However, there can be only one graphic card that will get to sit on the best graphics card throne. So, let’s find out which GPU deserves your hard-earned money with the AMD Radeon RX 7900 XTX vs Nvidia GeForce RTX 4090 showdown.
About AMD Radeon RX 7900 XTX
AMD‘s latest high-end offering is the flagship RX Radeon 7900 XTX, which replaces the Rx 6900 XT as AMD’s top graphics card. It is based on the new RDNA 3 architecture, which is based on the latest 5nm node used by other AMD chips as well.
The RDNA 3 architecture uses AI accelerators to improve graphics card performance and efficiency.
To get the most out of this new architecture, the AMD Radeon RX 7900 XTX has 6144 stream processors for optimal performance. It also comes with a 24 GB GDDR6 VRAM, which is based on a 384-bit reference design. As a result, the AMD RX 7900 XTX has a bandwidth carrying capacity of 960 GB/s. At its peak, the AMD RX 7900 XTX draws 350 TDP.
About Nvidia GeForce RTX 4090
The Nvidia GeForce RTX 4090 is the flagship GPU in the 4000 series. It replaces the RTX 3090 and is based on Nvidia’s new Ada architecture, which includes a neuron core for greater AI processing. The main performance gains from the Ada architecture come with AI computing and ray tracing.
Like the AMD Radeon RX 7900 XTX, the Nvidia GeForce RTX 4090 comes with 24 GB of VRAM. However, it uses the faster GDDR6X memory as opposed to the GDDR6 memory in the AMD Radeon RX 7900 XTX.
Due to the faster memory, the Nvidia GeForce RTX 4090 has a higher maximum bandwidth capacity, clocking in at 1,008 GB/s as opposed to the 960 GB/s of the AMD Radeon HD RX 7900 XTX. The faster memory and higher bandwidth require more power. Therefore, the Nvidia GeForce RTX 4090 has a TDP of 450 W.
The Geforce RTX 4090 and the Radeon RX 7900 XTX are the best-performing graphics cards each brand has to offer. However, when placed head-to-head, the battle there is a stark difference in the performance of the two graphics cards.
The Nvidia GeForce RTX 4090 has a better performance compared to the Radeon RX 7900 XTX, and the lead for team green widens when it comes to ray tracing performance. AMD needs to improve its abysmal ray tracing performance if it is to compete with Nvidia’s ray tracing performance.
The normal performance without DLSS or FSR enabled is also better on the Nvidia GeForce RTX 4090 as compared to the Radeon RX 7900 XTX.
Having said that, both of these graphics cards perform very differently in individual workloads. So, we have studied these two graphic cards thoroughly and will compare the performance of these two graphic cards in various workloads and games. Keep reading to find out.
The price is another very important factor for gamers. Ideally, a graphics card should have a good mix of performance and value. The Radeon RX 7900 XTX is the value-to-performance king and has a significant advantage over the Nvidia GeForce RTX 4090. AMD has kept pricing relatively competitive and set a $999 MSRP for the RX 7900 XTX in response to the exuberantly high $1599 price tag set by Nvidia for the GeForce RTX 4090.
So, the most important question is whether paying $600 more for the Nvidia GeForce RTX 4090 over the Radeon RX 7900 XTX is justifiable for an increase in performance. We will leave that to you to decide. However, we have provided a list of specifications to help with the decision-making.

Frequently Asked Questions
FAQ 1: Which one is the better graphics card, AMD Radeon RX 7900 XTX or Nvidia RTX 4090?
Answer: Based on the performance ratings, the Nvidia RTX 4090 is a better graphics card as it has a performance lead over the AMD Radeon RX 7900 XTX by 14 -18 % on average. However, considering that the RTX 4090 is costs $600 more than the Radeon RX 7900 XTX, the marginal performance difference is not justified.
FAQ 2: What is the Difference between DLSS 3 and FSR 3?
Answer: The DLSS 3 and the FSR 3 are proprietary AI super sampling and upscaling technologies of Nvidia and AMD, respectively. The DLSS 3 uses Nvidia’s Frame Generation with the 4-generation Tensor Cores to achieve better upscaling. AMD relies on its Fluid Motion Frame Technology. While being named differently, the purpose of both the DLSS 3 and FSR 3 is the same. They upscale resolution by generating “AI” frames that fill in the pixels, thus, putting less stress on the GPU.
