Sometimes, it's hard to visualise the difference in sensor measurements only by seeing specifications. The photograph below may give you a better sense of the sensor sizing in the 90D and K-3.

Plainly, both cameras have the same sensor dimensions albeit not the same MP. You should expect the Canon 90D to provide extra detail with its extra 9 Megapixels. Higher resolution can also enable you to crop photographs a bit more aggressively. The more recent 90D is going to have an advantage with regard to sensor innovation.
