GeForce RTX 3090 Ti vs Radeon RX 6400: In-Depth Breakdown
Performance: GeForce RTX 3090 Ti vs Radeon RX 6400
The GeForce RTX 3090 Ti is dramatically faster, around 543% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the GeForce RTX 3090 Ti is comfortable at 4K with upscaling and native 1440p, while the Radeon RX 6400 is better matched to entry-level 1080p.
Price & Value
The Radeon RX 6400 currently lists from $378, $2,063 less than the GeForce RTX 3090 Ti at $2,441. Despite being slower, the Radeon RX 6400 offers the better performance-per-dollar, so budget-focused buyers should weigh it carefully. The Radeon RX 6400 still sits about $219 above its $159 MSRP. The GeForce RTX 3090 Ti still sits about $442 above its $1,999 MSRP.
Power & Efficiency
At 53W against 450W, the Radeon RX 6400 is both the lower-power and the more efficient card, making it the easier build to cool and power.
VRAM & Future-Proofing
The GeForce RTX 3090 Ti carries 24GB versus 4GB on the Radeon RX 6400. The extra 20GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Features & Ecosystem
Beyond raw numbers, the Radeon RX 6400 brings AMD FSR upscaling and strong rasterization value, while the GeForce RTX 3090 Ti offers NVIDIA DLSS upscaling/frame generation and stronger ray tracing. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: Radeon RX 6400 or GeForce RTX 3090 Ti?
Choose the GeForce RTX 3090 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.
