Why isn't the CI build client comparing it's local cache against the git instance and only downloading the changes? That bandwidth figure leads me to believe each CI run is re-downloading the whole git tree. The CI server should be able to store or cache the git tree and download only the changes which should dramatically lower bandwidth.

The code/git is not the problem here. Text is tiny compared to the resulting binaries that you have to transfer to the machines that run the tests.

Cache these too and transfer with rsync? It performs miracles when the binaries are not compressed.

They are caching.
