Just a few days after the release of Nvidia’s flagship GeForce RTX 5090, Nvidia launched the GeForce RTX 5080, the second card in the GeForce RTX 50 Series. RTX 5080 is a more affordable solution and costs half of the RTX 5090. Even though the technical specifications of RTX 5080 are almost half of RTX 5090, RTX 5080 still packs a punch and is a very powerful card for 4K gaming. Let us find out how the RTX 5080 compares against its predecessor RTX 4080 SUPER and AMD’s flagship RX 7900 XTX on important parameters, including performance.
RTX 5080 vs RX 7900 XTX vs RTX 4080 SUPER Comparison
A quick comparison between RTX 5080, RTX 4080 SUPER, and RX 7900 XTX graphics cards based on their specifications, gaming performance, pricing, power consumption, and features.
GPU Architecture
GeForce RTX 5080 is built on Nvidia’s latest Blackwell GPU architecture on a 5nm manufacturing process. It uses GB203 GPU chip and has 10752 CUDA Cores, 84 RT Cores (4th Generation), and 336 Tensor Cores (5th Generation). On the other hand, RTX 4080 SUPER is built on the Ada Lovelace GPU architecture with a 5nm manufacturing process. It uses AD103 GPU chip and has 9725 CUDA Cores, 76 RT Cores (3rd Generation), and 304 Tensor Cores (4th Generation)
Radeon RX 7900 XTX is built on RDNA 3 GPU architecture. It uses a Chiplet design where the GPU package consists of a Graphics Compute Die (GCD) and multiple Memory Cache Dies (MCD) surrounding the GCD. The GCD is built on a 5nm fabrication process, while the MCD is built on a 6nm manufacturing process. The card uses Navi 31 GPU chip and has 6144 Stream Processors, 96 Ray Accelerators, and 192 AI Accelerators.

Final Words
RTX 5080 is no doubt a very good card with all the latest technology, but when it comes to raw performance, it does not offer a significant boost over the RTX 4080 SUPER or the RX 7900 XTX. Moreover, the power consumption and price of all three cards are almost identical. However, RTX 5080 supports newer technologies and display output ports, giving it an edge over its competitors.
