NVIDIA GeForce RTX 5090 vs RX 7900 XTX
Architecture
AMD Radeon RX 7900 XTX
- Constructed using AMD’s RDNA 3 architecture.
- Combines a 6nm Memory Cache Die (MCD) with a 5nm Graphics Compute Die (GCD) in a chiplet architecture.
- This design is the first GPU architecture to use it, increasing scalability and manufacturing efficiency.
- Allows DisplayPort 2.1, in contrast to the majority of NVIDIA GPUs.
NVIDIA GeForce RTX 5090
- According to the Blackwell architecture of NVIDIA.
- Manufactured with the specialized 4N manufacturing node (4nm-class) from TSMC.
- Emphasises ray tracing, AI acceleration, and rendering at extremely high resolution.
- Enhanced GPU utilization using two execution streams and sophisticated scheduling.
Gaming Performance
AMD Radeon RX 7900 XTX
- In the majority of 4K games, it closely rivals the RTX 4080 with its outstanding rasterization performance.
- Works effectively in contemporary games without ray tracing.
- Games that extensively rely on ray-traced effects will find it less suitable because of its lag in ray tracing performance compared to NVIDIA.
NVIDIA GeForce RTX 5090
- Provides outstanding 4K and 8K gaming performance.
- Even in situations requiring a lot of graphics, DLSS 4 dramatically increases frame rates.
- Excels at ray-traced titles with improved reflections, shadows, and lighting.
- Games such as Hogwarts Legacy and Cyberpunk 2077 exhibit up to a twofold boost in performance compared to the preceding generation.
