RTX 4080 Super vs RX 7900 XTX
Features, Software, Tech
Radeon RX 7900 XTX
FSR aid for compatibility
With OpenGL 4.6, DX12 Ultimate, HDMI, and ECC Memory, drivers
have improved over time, despite initial RDNA 3 difficulties.
Texture-intensive workloads benefit from VRAM.
Not as advanced as Nvidia’s software.
Nvidia RTX 4080 Super
Frame Gen + DLSS 3
Better AI and ray tracing support
Reflex, RTX Video Super Resolution, and Nvidia Broadcast.
A stronger driver-software ecosystem
Creatives and AI developers’ preferred platform
Video Game Performance
Radeon RX 7900 XTX
3% faster at 1080p (equal).
Around 4% quicker (tied) at 1440p.
At 4K, rasterisation is 7% faster, a significant advantage.
Winners include Call of Duty: MW2 (98 fps at 4K vs. 121).
A modest gameplay advantage for unray-traced games
Nvidia RTX 4080 Super
Some testing show a little 1080p advantage (~3%).
Higher-resolution trails.
Similar to or below the 7900 XTX in rasterisation.
Some games have a consistent frame rate.
Performance Ray Tracing
Gaming Performance
Radeon RX 7900 XTX
Raytracing performance is poor.
Losses average 28–36% across resolutions.
Behind Dying Light 2, Ratchet & Clank, and Cyberpunk 2077 in ray-traced games.
Complete route tracing increases pain.
The poorer ray tracing hardware slows it even with upscaling.
Nvidia RTX 4080 Super
Superior ray tracing performance by 30–70%.
Ratchet & Clank outperforms 7900 XTX by 59–74%.
Has a 90% lead in Minecraft complete path tracing (RTX).
Leads whether upscaling or not.
Much better RT hardware and optimisation
Upscaling and AI
Radeon RX 7900 XTX
FidelityFX Super Resolution 2/3 is supported.
Although FSR supports all GPUs and is more open, image quality is usually lower.
Hardware is replaced with shaders for frame generation.
Together, upscaling and ray tracing are slower.
Fewer people sponsor the less developed frame generation.
Nvidia RTX 4080 Super
Supports AI-powered, hardware-accelerated DLSS 3 (frame generation).
DLSS improves image quality and performance.
Strong game advantage with DLSS + RT
Frame generation and raw fps improvements boost fluidity.
A cutting-edge gaming technology for future professional and AI workloads.
Radeon RX 7900 XTX
SPECviewperf 2020 doubles CAD/engineering performance.
Improved rasterisation skills in Adobe Photoshop and Siemens NX programs.
LLM and large datasets benefit from 24GB VRAM.
Weaker AI acceleration limits training and steady diffusion.
Nvidia RTX 4080 Super
AI workload testing is 89%–156% faster.
Excellent AI training, Blender, and steady diffusion results
Strong FP16 and FP8 computation using Ada Lovelace architecture
Improved Tensor cores and CUDA for developers and AI

High power consumption during load (96.8W for 4K YouTube
streaming) and 19.1W idle power.
Increased heat output may require stronger cooling.
Nvidia RTX 4080 Super
TGP: 320W
More power-efficient, especially for light or idle tasks
31W for 4K YouTube playback 16.5W idle
Power reduction reduces heat, noise, and PSU needs.
Availability
Radeon RX 7900 XTX
Previously hard to find, now common.
A better price-to-performance ratio exists.
Nvidia RTX 4080 Super
Widely available yet often sold for $1,000+ over MSRP.
