Graphic Cards – 1080 vs 2K Resolution | TechEnclave

Why is CPU the bottleneck in 1080p resolution vs the graphics card in 2k gaming.
In 1920×1080, why doesn’t the CPU effectively switch over the job to the GPU?

 

Good question, usually Graphic cards puts in more effort to generate more pixels at higher resolutions in 2K but it is not required to render frames as frequently as the CPU for 1080p.

 

Imagine the CPU and the GPU work at the sweets shop, and their motive is to ship out as many sweets boxes (frames) as possible per unit of time (second).
GPU fills the boxes, and CPU packs and delivers to the customers in line.

It takes some time to fill the box (GPU rendering of the frame), based on the amount of sweets per box or box size (graphics quality and frame resolution).
But it takes similar time to pack and deliver irrespective of the box size and amount of sweets in it.

So for larger boxes of sweets (larger frames) or more number of sweets per box (higher graphics quality), GPU will take more time and CPU will feel relaxed.
But for smaller boxes (lower resolution) GPU will fill more number of boxes per unit of time (frames per second) and CPU will have to work harder to keep up when packing and delivering.
