GeForce GTX 1080 Ti vs Radeon RX Vega 56: In-Depth Breakdown
Performance: GeForce GTX 1080 Ti vs Radeon RX Vega 56
The GeForce GTX 1080 Ti is dramatically faster, around 42% ahead of the Radeon RX Vega 56. That gap is enough to move it up a tier: the GeForce GTX 1080 Ti is comfortable at 1080p, while the Radeon RX Vega 56 is better matched to entry-level 1080p.
Price & Value
Right now the Radeon RX Vega 56 starts at $1,105 AUD against $2,385 AUD for the GeForce GTX 1080 Ti. Despite being slower, the Radeon RX Vega 56 offers the better performance-per-dollar (~52% better value), so budget-focused buyers should weigh it carefully. The Radeon RX Vega 56 still sits about $706 AUD above its $399 AUD MSRP. The GeForce GTX 1080 Ti still sits about $1,686 AUD above its $699 AUD MSRP.
Power & Efficiency
The Radeon RX Vega 56 is the lighter draw at 210W against the GeForce GTX 1080 Ti's 250W, making it the easier card to power and cool. The GeForce GTX 1080 Ti draws more in absolute terms but squeezes out more performance per watt, so budget for a beefier PSU if you go that route.
VRAM & Future-Proofing
The GeForce GTX 1080 Ti's 11GB (vs 8GB on the Radeon RX Vega 56) gives it more room for 4K textures and memory-hungry creative or AI workloads.
Features & Ecosystem
Beyond raw numbers, the GeForce GTX 1080 Ti brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX Vega 56 offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce GTX 1080 Ti or Radeon RX Vega 56?
Choose the GeForce GTX 1080 Ti if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX Vega 56 stretches your money further for only slightly lower performance.
