GeForce RTX 3080 Ti vs Radeon RX 6800: In-Depth Breakdown

Performance: GeForce RTX 3080 Ti vs Radeon RX 6800

The GeForce RTX 3080 Ti is significantly faster, around 26% ahead of the Radeon RX 6800. Both cards sit in the same broad class, well suited to 1440p.

Price & Value

Right now the Radeon RX 6800 starts at $4,559 BRL against $9,915 BRL for the GeForce RTX 3080 Ti. Despite being slower, the Radeon RX 6800 offers the better performance-per-dollar (~73% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6800 still sits about $3,980 BRL above its $579 BRL MSRP. The GeForce RTX 3080 Ti still sits about $8,716 BRL above its $1,199 BRL MSRP.

Power & Efficiency

The Radeon RX 6800 sips power at 250W next to the GeForce RTX 3080 Ti's 350W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU.

VRAM & Future-Proofing

The Radeon RX 6800's 16GB (vs 12GB on the GeForce RTX 3080 Ti) gives it more room for 4K textures and memory-hungry creative or AI workloads.

Features & Ecosystem

Beyond raw numbers, the GeForce RTX 3080 Ti brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6800 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 6800?

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 6800 stretches your money further for only slightly lower performance.

Frequently Asked Questions

Is the GeForce RTX 3080 Ti better than the Radeon RX 6800?

The GeForce RTX 3080 Ti is significantly faster, roughly 26% ahead. The Radeon RX 6800 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 6800?

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 $5,356 BRL over the Radeon RX 6800?

Only if you need the extra performance or features; on pure value the Radeon RX 6800 comes out ahead.

Does the Radeon RX 6800 have enough VRAM advantage to matter?

Its 16GB (vs 12GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.

Which should you buy: GeForce RTX 3080 Ti or Radeon RX 6800?

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 6800 stretches your money further for only slightly lower performance.
