GeForce GTX 1070 vs GeForce GTX 1660 Ti

Speed and memory

In our performance index the GeForce GTX 1070 scores 16 and the GeForce GTX 1660 Ti scores 14, which makes the GeForce GTX 1070 about 14% faster. That is a visible but modest gap, usually 5 to 10 fps in a game that runs at 60.

The GeForce GTX 1070 has 8 GB of video memory and the GeForce GTX 1660 Ti has 6 GB. That is a small difference and unlikely to decide anything.

In our estimates for popular games at 1080p on High, the biggest gap is in Call of Duty (42 against 37 fps), and the smallest is in Red Dead Redemption 2 (58 against 52 fps). Games that are light enough to run above 200 fps on both cards show little difference at all.

Power and value

The GeForce GTX 1070 is rated at 150 W and the GeForce GTX 1660 Ti at 120 W. With a mid-range processor that means a power supply of about 550 W for the first and 450 W for the second. The power draw is close enough that cooling and noise will be similar.

At launch the GeForce GTX 1070 cost $379 and the GeForce GTX 1660 Ti $279. Per dollar, the GeForce GTX 1660 Ti gave more performance (5.0 points per $100 against 4.2). Current prices differ, so run the same sum on what you can actually buy today.

Which one to buy

Choose the GeForce GTX 1070 if you want the faster card, and it also has at least as much memory. It makes the most sense at 1440p and above, or on a monitor with a high refresh rate.

Choose the GeForce GTX 1660 Ti if the price gap matters more than the 14% speed difference, or if you want lower power draw and a quieter PC. Whichever you pick, check reviews for the games you play, because two cards with similar scores can differ in individual titles.
