View Full Version : how many PCIe lanes does an RTX 2080Ti need?

How does a graphics card, particularly the RTX 2080Ti, utilise PCIe lanes?

I want to buy a PCIe SSD with a x8 connection that I wish to use in my build, though my CPU (8700K) only supports 16 PCIe lanes.

I know if I put in the SSD, the gpu will go from x16 mode to x8 mode. But what kind of performance reduction would I see if the gpu runs in x8 mode?
Does the GPU even use all 16 lanes at full load?
Will the GPU max out x8 bandwidth @ full load?

Hello,

The performance delta between 16x and 8x lane speed is normally within margin of error.
