GeForce RTX 4060 Ti 8GB vs Radeon RX 6400: In-Depth Breakdown
Performance: GeForce RTX 4060 Ti 8GB vs Radeon RX 6400
The GeForce RTX 4060 Ti 8GB is dramatically faster, around 333% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the GeForce RTX 4060 Ti 8GB is comfortable at 1440p, while the Radeon RX 6400 is better matched to entry-level 1080p.
Price & Value
The Radeon RX 6400 currently lists from $175 GBP, $649 GBP less than the GeForce RTX 4060 Ti 8GB at $824 GBP. Despite being slower, the Radeon RX 6400 offers the better performance-per-dollar (~8% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 4060 Ti 8GB still sits about $425 GBP above its $399 GBP MSRP.
Power & Efficiency
On power, the Radeon RX 6400 is the gentler choice at 53W versus 160W. The GeForce RTX 4060 Ti 8GB is more efficient per watt because it's faster, but its higher 160W draw means more heat and a bigger PSU. Its more modern Ada Lovelace architecture on a TSMC N4 process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 4060 Ti 8GB carries 8GB versus 4GB on the Radeon RX 6400. The extra 4GB 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 GeForce RTX 4060 Ti 8GB 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 4060 Ti 8GB or Radeon RX 6400?
Choose the GeForce RTX 4060 Ti 8GB 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.
