iPhone X vs iPhone XS

At Fritz, we collect performance data every time a model is run on a user’s device to make sure that experiences are consistent. I went and looked at real world data from our open-source Fritz AI Studio app to see how each Apple device stacked up.

Core ML performance by device. Higher is better. Note the y-axis is logarithmic. Data from Fritz.

This Core ML model runs over 10X faster on the A12 processor in the iPhone XS Max compared with the iPhone X. The model above performs object detection, and results vary from model to model. The smallest speed-up I saw was around 5x.

The 6th Gen iPad appears faster than the iPhone X here. This model just squeaked through my threshold for having enough data to be included here, so it’s possible that this is just noise. I’ll revisit this in a future post.*
