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 550% 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 $10 EUR against $966 EUR for the GeForce RTX 3080 Ti. Despite being slower, the Radeon RX 6400 offers the better performance-per-dollar (~1344% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6400 is trading below its $159 EUR MSRP — a genuine deal. The GeForce RTX 3080 Ti is trading below its $1,199 EUR MSRP — a genuine deal.

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. Its more modern RDNA 2 architecture on a TSMC N6 process is part of why it does more with each watt.

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.

Frequently Asked Questions

Is the GeForce RTX 3080 Ti better than the Radeon RX 6400?

The GeForce RTX 3080 Ti is dramatically faster, roughly 550% ahead. The Radeon RX 6400 is still worth it if value matters more than top-end frames.

Which is better for 4K gaming, the GeForce RTX 3080 Ti or the Radeon RX 6400?

Neither is a dedicated 4K card; both are best at 1440p. For 4K you'd want a faster GPU, or lean on upscaling.

Is the GeForce RTX 3080 Ti worth the extra $955 EUR over the Radeon RX 6400?

Only if you need the extra performance or features; on pure value the Radeon RX 6400 comes out ahead.

Does the GeForce RTX 3080 Ti have enough VRAM advantage to matter?

Its 12GB (vs 4GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
