RTX 2060 vs GTX 1660 Super at each resolution
| Resolution | RTX 2060 | GTX 1660 Super |
|---|---|---|
| 1080p | Good (2 short of Great) | Good (6 short of Great) |
| 1440p | Not ideal (10 short of Playable) | Not ideal (14 short of Playable) |
| 4K | Not ideal (22 short of Playable) | Not ideal (26 short of Playable) |
On our rating lines the RTX 2060 (28) and GTX 1660 Super (24) land on the same verdict at every resolution, so the 4-point index gap does not move either card into a different class. Memory, power and the price you can find decide it.
Power, PSU and efficiency
Reference board power is 160W for the RTX 2060 and 125W for the GTX 1660 Super, a 35W difference. Per 100W that works out to 17.5 index points for the RTX 2060 and 19.2 for the GTX 1660 Super, so the GTX 1660 Super does more per watt. An existing 450W supply meets the maker guidance for the GTX 1660 Super but not for the RTX 2060 (500W). Full sizing: RTX 2060 PSU · GTX 1660 Super PSU.

Frequently asked questions
Is the RTX 2060 better than the GTX 1660 Super?
On our relative index the RTX 2060 is about 17% ahead of the GTX 1660 Super. Both carry 6GB of VRAM. The smaller the gap, the more other factors like price, VRAM and features should decide it.
Which is better value, the RTX 2060 or the GTX 1660 Super?
Value depends on the price you can find each at. The slower card is usually the smart buy if it is meaningfully cheaper, unless you need the extra VRAM or features of the faster one.
Do the RTX 2060 and GTX 1660 Super need different power supplies?
The RTX 2060's maker lists a 500W supply and the GTX 1660 Super's lists 450W; our starting classes are 550W and 450W. If you might move to the RTX 2060 later, size for its 500W now.
