Performance Comparison
Rasterization (1440p)
RX 8800 XT edges ahead in pure pixel throughput at this resolution due to RDNA 4 efficiency.
Ray Tracing
RTX 5080's dedicated ray cores and NVIDIA's mature RT optimization significantly outpace AMD's RT performance.
AI & Tensor Workloads
RTX 5080 dominates with native CUDA, TensorRT, and widespread software support; RX 8800 XT lacks equivalent ecosystem.
Frame Generation
Both support frame generation (FSR 3 vs DLSS 4), but RTX 5080's full-GPU upsampling in DLSS 4 offers slight edge.
Power Efficiency
RX 8800 XT typically draws 10–15% less power than RTX 5080 at comparable performance.
Value (Price/Performance)
RX 8800 XT offers better rasterization-per-dollar; RTX 5080 justifies premium via ray tracing and AI capability.

Frequently Asked Questions
For pure rasterization performance at 1440p–4K, the RX 8800 XT edges out the RTX 5080. However, if ray tracing is important, the RTX 5080 dominates with significantly better RT core performance and DLSS 4 frame generation.
FSR 3 (AMD) uses fixed frame generation, while DLSS 4 (NVIDIA) combines fixed generation with full-GPU AI upsampling for potentially sharper image quality. Both technologies improve frame rates but operate through slightly different pipelines.
The RTX 5080 is vastly superior for AI/ML due to native CUDA support, mature cuDNN libraries, and widespread professional software compatibility. The RX 8800 XT lacks equivalent ecosystem support for these workloads.
