Benchmark results demonstrating that PCI-Express x8 vs x16 speeds don’t impact GPU rendering performance.
Impact of PCI-E Speed on Gaming Performance
Many hardware sites have shown in the past that video cards do not show any performance decrease by running in x8 mode and cannot utilize the larger bandwidth provided by the latest Gen3 specification. However, video cards are getting faster and faster so we felt it this is still true. Also, with the gaining popularity of 4k displays, we also felt it was important to see if the PCI-E revision/speed would affect a video card’s performance at the much more demanding 4k resolution.
