Radeon RX 6600 vs GeForce RTX 3060 12GB: specs comparison

Radeon RX 6600 came out in 2021 on the RDNA 2 architecture, GeForce RTX 3060 12GB in 2021 on Ampere. Radeon RX 6600 has 8 GB of GDDR6 on a 128-bit bus (224 GB/s), GeForce RTX 3060 12GB has 12 GB of GDDR6 on a 192-bit bus (360 GB/s). Power draw: 132 W vs 170 W. Recommended PSU: 450 W for Radeon RX 6600 and 550 W for GeForce RTX 3060 12GB. Cores and clocks from different vendors are not directly comparable, so those rows are not highlighted.

In short. The table below is built from the official spec sheets. Green marks the best value in a row, and under the table you will see which resolutions the VRAM is enough for. This is not an FPS benchmark.

Which is better for 1080p, 1440p and 4K

  • 1080pEnough VRAM on both: Radeon RX 6600, GeForce RTX 3060 12GB. Higher memory bandwidth: GeForce RTX 3060 12GB (360 GB/s)
  • 1440pEnough VRAM: GeForce RTX 3060 12GB
  • 4KBoth cards have less than 16 GB of VRAM — expect medium settings in new games.

Based on actual specs: 8 GB of VRAM or more for 1080p, 12 GB for 1440p and 16 GB for 4K at high settings in new games. This is not an FPS benchmark: we don’t show scores we can’t back with a source.

FAQ

Which is better — RX 6600 or RTX 3060 12GB?
It depends on resolution and budget. By VRAM: 1080p: Enough VRAM on both: Radeon RX 6600, GeForce RTX 3060 12GB. Higher memory bandwidth: GeForce RTX 3060 12GB (360 GB/s). 1440p: Enough VRAM: GeForce RTX 3060 12GB. 4K: Both cards have less than 16 GB of VRAM — expect medium settings in new games.. There are no FPS benchmarks in the table — check tests in the specific games you play.
How much VRAM do RX 6600 and RTX 3060 12GB have?
RX 6600 has 8 GB of GDDR6 with 224 GB/s of bandwidth, RTX 3060 12GB has 12 GB of GDDR6 and 360 GB/s.
What PSU do RX 6600 and RTX 3060 12GB need?
The vendors recommend a 450 W power supply for RX 6600 and 550 W for RTX 3060 12GB. Power connectors: RX 6600 — 1×8-pin, RTX 3060 12GB — 1×8-pin.
Why are the cores of RX 6600 and RTX 3060 12GB not highlighted?
The “better” highlight on cores and clocks appears only when the cards come from the same vendor and form factor. NVIDIA, AMD and Intel cores are built differently, and laptop GPU clocks depend on the power limit set by the laptop maker.
Can I add a third graphics card?
Yes. Open the interactive comparison — the pair is already selected, you can add two more models and share the link.
Where do the specs come from?
From the official NVIDIA, AMD and Intel spec sheets — each model in the table header links to its vendor page. Bandwidth is calculated as “memory speed × bus width / 8”.
