Steel Nomad 9070 XT/9800x3D with igpu on and turned off

So i was doing a bit of testing and put my ASUS Prime 9070 XT OC through Steel Nomad and figured i got a score of 6500-6700 which isnt very high, below average. I turned off my iGPU and redid the test and got a score of 7030 - 7100

Is this normal or is something wrong with my setup that the igpu messes so bad with the "performance"?
