RTX 4080 SUPER is the last SUPER card launched in the GeForce RTX 40 series from Nvidia. It is officially a replacement for the older RTX 4080 and that too with a slight increase in performance but a significant reduction in the price. It now also becomes the second most powerful card in the GeForce RTX 40 series lineup after the mighty RTX 4090. The main competitor of RTX 4080 SUPER from AMD is the Radeon RX 7900 XTX which is AMD’s flagship and fastest card in the Radeon RX 7000 series. So, if you want to know how the RTX 4080 SUPER stacks against its competitors in all major areas then please go through the comparison below.
RTX 4080 SUPER vs RX 7900 XTX vs RTX 4080 Comparison
A quick comparison between RTX 4080 SUPER, RX 7900 XTX, and RTX 4080 graphics cards based on their specifications, gaming performance, pricing, power consumption, and features.
GPU Architecture
RTX 4080 SUPER and RTX 4080 are built on the Ada Lovelace architecture on a smaller 5nm fabrication process. Both cards use the same use AD103 chip whereas RTX 4080 SUPER uses the chip in its full capacity with slightly more cores compared to the RTX 4080. RTX 4080 SUPER comes with 10240 CUDA Cores, 80 RT Cores (3rd Generation), and 320 Tensor Cores (4th Generation). On the other hand, RTX 4080 comes with 9728 CUDA Cores, 76 RT Cores (3rd Generation), and 304 Tensor Cores (4th Generation).
Radeon RX 7900 XTX is built on AMD’s RDNA 3 GPU architecture and features a Chiplet design for maximizing performance and lowering costs. The GPU package consists of a Graphics Compute Die (GCD) and multiple Memory Cache Dies (MCD) that surround the GCD. The GCD is built on a 5nm fabrication process whereas MCD is built on a 6nm manufacturing process. The card uses a Navi 31 GPU chip and comes with 6144 Stream Processors, 96 Ray Accelerators, and 192 AI Accelerators.

Final Words
Well, RTX 4080 SUPER does not bring anything new to the table as it is almost an RTX 4080. The only good thing about the RTX 4080 SUPER is the price cut and that too by a great margin. This makes RTX 4080 SUPER a great proposition for buyers who want to have a high-end 1440p and 4K gaming experience at a competitive price. Radeon RX 7900 XTX from AMD is a pretty good card and a great purchase if you don’t mind the higher power consumption and relatively lower Realtime Ray Tracing Performance.
