GeForce RTX 3080 Ti vs Radeon RX 6400: In-Depth Breakdown
Performance: GeForce RTX 3080 Ti vs Radeon RX 6400
The GeForce RTX 3080 Ti is dramatically faster, around 486% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the GeForce RTX 3080 Ti is comfortable at 1440p, while the Radeon RX 6400 is better matched to entry-level 1080p.
Price & Value
Right now the Radeon RX 6400 starts at $378 against $2,881 for the GeForce RTX 3080 Ti. Despite being slower, the Radeon RX 6400 offers the better performance-per-dollar (~30% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6400 still sits about $219 above its $159 MSRP. The GeForce RTX 3080 Ti still sits about $1,682 above its $1,199 MSRP.
Power & Efficiency
The Radeon RX 6400 draws just 53W versus 350W for the GeForce RTX 3080 Ti, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.
VRAM & Future-Proofing
With 12GB against 4GB, the GeForce RTX 3080 Ti has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6400's 4GB can fall short.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 3080 Ti brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6400 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 RTX 3080 Ti or Radeon RX 6400?
Choose the GeForce RTX 3080 Ti if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 6400 stretches your money further for only slightly lower performance.
