Does 720p give 2x fps compared to 1080p?

Ashish Joseph · Jul 24, 2014

Say, you are gaming on 1080p, on ultra settings and you get 30 fps
So, with the same build, same game and the same settings(ultra,etc), and on 720p instead of 1080p, will it give 60 fps?

Yes it should, even though 720P isn't exactly 2 times smaller than 1080P, it will yield a lot more fps. The framerate will depend on what game you play.

it won't give double ut frames will increase its different from game to game

Ashish Joseph :

Short answer is: No.

Longer answer: There is way more to consider than just lower resolution = higher framerates. If you are getting 30fps at 1080p there is no guarantee that the reason you are only getting 30fps is the resolution, it may RAM, CPU, post-processing, physics, particles, etc...
But let's say it is 100% resolution that is capping you at 30fps, even then 1280x720 is not half of 1920x1080, so you are not cutting the load in half when dropping the resolution to 720. You would have to drop it to 540p in order to reduce the performance hit of the resolution by half.

No. It would increase a lot but it would not double it. Like sthapns247 said, half 1080p is 540p.

While I agree with almost everything sthapns247, he is wrong about 540p being half. 540p is 1/4. Remember your pixel count is in 2D, it is not a line.

1920*1080 = 4x 960*540 = 2,073,600
1280*720 = 920,600

720p is a little less than half the pixels.

But rendering twice as many pixels does not mean twice as much time. There are lots of factors as mentioned.
