"The competition this round is one of our test benches, running an Intel Core i7-6320 and 32GB of memory. "
Really?, and perhaps if you managed to link to said i7 that would be good.
"The test bench was running only an i3, which explains the lower CPU and overall scores"
Ahhhh, so not an i7 then.
As others have pointed out... Why? If this is a GPU comparison, then surely the CPU should not be a factor. If the tests you are running are bottlenecked by the CPU on the laptop, then so be it; let it show in the results, because it's not like I can easily replace/select the desired laptop CPU to prevent that. There are enough differences in the other motherboard componentry and even layout, that some of these comparisons are never going to be like for like, so there is no need to have an obviously challenged desktop in the mix.
Even if the laptop is "slower" and you explain it away as the CPU differences, that is fine, because at least I can make the informed choice of form factor affecting performance.
If you wanted to have like for like, then at least choose a desktop CPU with the same core count. If you cant get one with the same GHz/TDP, then throttle it, but there should still be an unthrottled desktop comparison, so we can see the difference, or lack of.
