Gaming Performance
Estimated average FPS in a typical AAA game, from the FPS Calculator’s formula, with the Ryzen 7 9800X3D so the cards are the limit. * marks a figure held back by the CPU. Ray tracing, upscaling and frame generation are not included.
| Resolution, settings | RTX 2060 6GB | RTX 3060 12GB | Difference |
|---|---|---|---|
| 1080p, high | 75 | 85 | RTX 3060 12GB +13% |
| 1440p, high | 46 | 58 | RTX 3060 12GB +26% |
| 4K, high | 24 | 36 | RTX 3060 12GB +51% |
| 1080p, ultra | 54 | 68 | RTX 3060 12GB +26% |
| 1440p, ultra | 33 | 46 | RTX 3060 12GB +42% |
| 4K, ultra | 19 | 26 | RTX 3060 12GB +36% |
VRAM
RTX 2060 6GB: 6GB of VRAM is enough for high (not ultra) textures at 1080p and below the 12GB our VRAM rule asks for at 1440p and 4K high settings, so expect to lower texture quality there.
RTX 3060 12GB: 12GB of VRAM is enough for ultra textures at 1080p and 1440p and enough for high (not ultra) textures at 4K.
With Your CPU
A faster card only pays off when your CPU can feed it. Here is each card with common processors in our bottleneck engine (typical AAA game, high settings). “GPU-limited” is normal; a CPU % is how much of the card goes unused.
| CPU | RTX 2060 6GB | RTX 3060 12GB |
|---|---|---|
| Core i3-12100F | GPU-limited / GPU-limited | GPU-limited / GPU-limited |
| Ryzen 5 5600 | GPU-limited / GPU-limited | GPU-limited / GPU-limited |
| Core i5-12400F | GPU-limited / GPU-limited | GPU-limited / GPU-limited |
| Ryzen 5 7600 | GPU-limited / GPU-limited | GPU-limited / GPU-limited |

Power and PSU
With a Ryzen 5 7600, the PSU Calculator recommends 500W for a PC with the RTX 2060 6GB and 550W with the RTX 3060 12GB. The makers’ own recommendations are 500W and 550W.
Which Should You Buy?
- Buy the RTX 3060 12GB for more performance: about 13% higher in our index. It is worth it if the price difference is smaller than that.
- The RTX 2060 6GB makes sense when it costs clearly less, or when its other strengths below matter more to you.
- For 1440p, 4K or keeping the card for years, the RTX 3060 12GB’s extra VRAM is the safer choice.
