Short answer
Buy the RX 6700 XT for raw gaming value. Buy the RTX 3060 for NVIDIA features.
For most people building a used gaming PC, the RX 6700 XT is the better card if condition and price are similar. It was aimed at a higher performance tier and still feels more comfortable at 1440p. The RTX 3060 12GB is not a bad card; it is just easier to justify when you specifically want DLSS, CUDA support, lower power draw or NVIDIA's creator and streaming extras.
you mostly play lighter games, need CUDA, want DLSS, have a modest PSU, or find a clean 12GB card meaningfully cheaper.
you want higher traditional gaming performance, especially at 1440p, and your case and power supply can handle it.
Specs that actually matter
Do not compare these cards by VRAM alone. The common RTX 3060 12GB and RX 6700 XT both carry 12GB of GDDR6 on a 192-bit bus, but the RX 6700 XT has more gaming muscle behind that memory. AMD also gives it a 96MB Infinity Cache, while NVIDIA counters with stronger support for DLSS, CUDA workloads and RTX-era software features.
| Spec | RTX 3060 12GB | RX 6700 XT |
|---|---|---|
| Architecture | NVIDIA Ampere | AMD RDNA 2 |
| Core layout | 3584 CUDA cores | 40 compute units / 2560 stream processors |
| Memory | 12GB GDDR6, 192-bit | 12GB GDDR6, 192-bit |
| Typical board power | Usually around 170W on 12GB partner cards | 230W reference board power |
| Best fit | 1080p, esports, CUDA, DLSS, lower-power builds | High-refresh 1080p and stronger 1440p gaming |
Avoid mixing up the RTX 3060 12GB with the later RTX 3060 8GB. The 8GB card uses a narrower 128-bit memory interface and is not the card most people mean when they praise the RTX 3060's 12GB memory buffer.
1080p and 1440p gaming
At 1080p, both cards are still useful. The RTX 3060 handles esports titles, older AAA games and medium-to-high settings well. It is a comfortable card for someone who wants a sensible 1080p machine without chasing every ultra preset.
The RX 6700 XT is the more interesting gaming card. It has enough raster performance to push higher frame rates and it ages better when you move from 1080p to 1440p. If you are buying for a 1440p monitor, the RX 6700 XT should be the default pick unless the RTX 3060 is much cheaper or you need NVIDIA-specific features.
RTX 3060 is fine; RX 6700 XT gives more headroom for demanding games and high refresh rates.
RX 6700 XT is the more natural fit. RTX 3060 can do it, but settings compromises arrive sooner.
Ray tracing, DLSS, FSR and creator work
This is where the RTX 3060 earns its place. NVIDIA's ray tracing stack and DLSS support are stronger in many games, and CUDA still matters for plenty of creator, AI and production tools. If you are buying a GPU partly for Blender, Stable Diffusion experiments, video workflows or CUDA-only software, the RTX 3060 can be the smarter buy even when it is slower in normal gaming.
The RX 6700 XT supports ray tracing, but that is not its headline strength. Think of it as a fast traditional gaming GPU with enough VRAM, not as the card you buy because you want every ray-traced setting enabled. AMD FSR helps in supported games and is widely available, but the RTX 3060 still has the cleaner feature argument.
Power, thermals and system fit
The RTX 3060 is easier to fit into modest systems. Many partner cards sit around the 170W range, which makes it friendlier for smaller cases, quieter coolers and older power supplies. That can matter if you are upgrading a prebuilt PC or a budget system where the PSU is not something you want to replace immediately.
The RX 6700 XT draws more power. AMD lists 230W typical board power and a 650W PSU recommendation for the reference card. That is not extreme, but it does mean you should check connectors, case airflow and card length before buying. A cheap RX 6700 XT stops being cheap if it forces a rushed PSU upgrade.
Used buying checks before you message the seller
With either card, condition beats branding. A clean RTX 3060 from a careful owner can be a better purchase than an abused RX 6700 XT with vague photos and no testing proof. Start with the exact model name, then check the cooler, ports, screws, warranty stickers and whether the seller can show a recent benchmark or game test.
- Ask for the exact model, not just “RTX 3060” or “6700 XT”.
- Check whether the RTX 3060 is the 12GB version.
- Ask for a recent photo of the card and a running test.
- Look for fan noise, high hotspot temperatures or display artifacts.
- Confirm power connectors and physical length before paying.
- Use the original marketplace payment flow when protection depends on it.
Pricing advice: how much more is the RX 6700 XT worth?
The RX 6700 XT should cost more than an RTX 3060 12GB, but not by a silly amount. If the difference is small, the AMD card is usually the better gaming buy. If the RX 6700 XT costs far more, compare it against newer used options before assuming it is still the value choice.
A simple rule: if your only goal is gaming performance, start with the RX 6700 XT. If the RTX 3060 is substantially cheaper, cleaner, quieter or better suited to your software, it still deserves a look. The best used GPU is rarely the one with the loudest spec sheet; it is the one with the right price, condition and fit for your system.

FAQ
Is the RTX 3060 12GB better because it has the same VRAM?
No. Matching VRAM capacity does not mean matching performance. The RX 6700 XT is usually faster in normal gaming despite also having 12GB of GDDR6 memory.
Is the RX 6700 XT good for 1440p?
Yes, it is a sensible used 1440p card if the price and condition are right. It is a much more natural 1440p choice than the RTX 3060.
Should streamers choose the RTX 3060?
Often, yes. NVIDIA's encoder support and software ecosystem are still a strong reason to buy RTX if streaming or creator tools matter as much as raw game performance.
