Gaming Performance
AMD Radeon RX 7900 XTX
- About 3% quicker at 1080p (about equal)
- At 1440p, around 4% faster (still tied)
- Approximately 7% quicker at 4K a considerable advantage in high-resolution rasterization
- Wins in some titles, such as Call of Duty: MW2 (98 fps at 4K versus 121 fps)
- A slight edge in unray-traced games’ raw gameplay performance
Nvidia GeForce RTX 4080 Super
- Some tests have a little edge at 1080p (~+3%).
- Somewhat trails at higher resolutions.
- Usually in rasterisation on par with or just below the 7900 XTX
- Some titles have more steady frame pace.
Ray Tracing Performance
AMD Radeon RX 7900 XTX
- Clearly worse performance in ray tracing
- Average loss across resolutions of 28–36%
- Far behind in ray-traced video games such as Dying Light 2, Ratchet & Clank, and Cyberpunk 2077
- When complete route tracing is enabled, the pain is increased.
- Even with upscaling, it lags since the ray tracing hardware is inferior.
Nvidia GeForce RTX 4080 Super
- Dominates ray tracing with performance that is 30–70% better.
- Ratchet & Clank is 59–74% quicker than 7900 XTX (RT on).
- Maintains a 90% lead in complete path tracing (RTX) in Minecraft.
- Keeps the lead whether upscaling is done or not.
- Much improved RT hardware and optimisation
Upscaling and AI Technologies
AMD Radeon RX 7900 XTX
- FSR 2/3 (FidelityFX Super Resolution) is supported.
- Although FSR supports all GPUs and is more open, the image quality is typically worse.
- Shaders are used instead of hardware for frame generation.
- Slower when combining upscaling and ray tracing
- Frame generation is less developed and sponsored by fewer people.
Nvidia GeForce RTX 4080 Super
- Supports the AI-powered and hardware-accelerated DLSS 3 (with frame generation).
- DLSS offers smoother performance and higher-quality images.
- Strong advantage when using DLSS + RT in games
- Fluidity is added via frame generation in addition to raw fps improvements.
- A significant edge in gaming technology for the future
Professional and AI Workloads
AMD Radeon RX 7900 XTX
- SPECviewperf 2020 performance (CAD, engineering applications) is doubled.
- More adept at rasterisation operations in Adobe Photoshop
- Could perform well in Siemens NX applications.
- Has 24GB of VRAM, which is useful for LLM work and some huge datasets.
- Training tasks and stable diffusion are limited by weaker AI acceleration.
Nvidia GeForce RTX 4080 Super
- Much quicker in testing (89%–156% faster) in AI workloads
- Outstanding results in AI training, Blender, and stable diffusion
- Utilizing the Ada Lovelace architecture, robust FP16 and FP8 computation
- Better Tensor cores and the CUDA environment for developers and AI
- Preferred for professional rendering and AI creation
