Generally speaking, you can set the power target of a high-spec GPU below 100% to get most of the performance at significantly reduced power draw. So if you're cost sensitive it's still probably better to get a dGPU, just cap the power. The dGPUs have more cores and wider memory buses/dedicated memory which delivers higher performance than the space constrained integrated GPUs.
