The Constant growth model does not address risk; it uses the current market price, as the reflection of the expected risk return preference of investor in marketplace, whereas CAPM consider the firm's risk, as reflected by beta, in determining required return or cost of ordinary share equity.Another difference is that when constant growth model is used to find the cost of ordinary share equity, it can easily be adjusted with flotation cost to find the cost of new ordinary share capital. whereas CAPM does not provide simple adjustment.Although CAPM Model has strong theoretical foundation, the ease of the calculation of the constant growth model justifies it use.
If a linear model accurately reflects the measured data, then the linear model makes it easy to predict what outcomes will occur given any input within the range for which the model is valid. I chose the word valid, because many physical occurences may only be linear within a certain range. Consider applying force to stretch a spring. Within a certain distance, the spring will move a linear distance proportional to the force applied. Outside that range, the relationship is no longer linear, so we restrict our model to the range where it does work.

Markowitz is a normative theory while CAPM is a positive theory.

The capital asset pricing model (CAPM) is the dominant model for estimating the cost of equity.
Empirical evidence of the Capital Asset Pricing Model (CAPM) includes studies that have found a positive relationship between the expected return on an asset and its beta, as predicted by the model. However, empirical studies have also highlighted challenges such as the presence of anomalies that do not fit with the CAPM's assumptions, casting doubt on its ability to fully explain asset pricing in all market conditions.

The Capital Asset Pricing Model is a pricing model that describes the relationship between expected return and risk. The CAPM helps determine if investments are worth the risk.
It is a linear model.
It's a measure of how well a simple linear model accounts for observed variation.
