www.notebookcheck.net has been doing some testing which is quite interesting on Intel CPUs with Iris XE GPU. If you run a test that runs mainly on the CPU it throttles at a particular TDP. On a gaming test one machine performed at 40% of the frame rate expected from an Iris XE, it appears that the TDP throttling occurs as the TDP is shared between the CPU and GPU.
An Iris XE GPU has a 3D score of 2688 which in the ball park of a GeForce GTX 860M by the way.
So it depends on your system's cooling but it looks like you can expect less performance on some laptops than the CPU/GPU might be expected to give on paper.
So for trainz a big tower case with lots of room for cooling probably is best for Trainz performance and a cheap laptop might well perform close to a more expensive one simply because of the TDP throttling the higher end CPUs and GPUs.
