Running Gemma-4-E2B-it on an iPhone 15 (can't go higher than that due to RAM limitations) versus a Pixel 9 Pro, I don't really notice much of a difference between the two. The Pixel is a bit faster, but also a year more recent.

The model itself works absolutely fine, though the iPhone thermal throttles at some point which really reduces the token generation speed. When I asked it to write me a business plan for a fish farm in the Nevada desert, it slowed down after a couple thousand tokens, whereas the Pixel seems to just keep going.

You can run Android on just about anything so it boils down to Linux GPU benchmarks.
