I think they also have some TensorFlow-specific SYCL kernels; I'm not sure it all goes through Eigen. Plus they're at TF 1.6, whereas AMD's HIP version seems to be stuck on TF 1.0. AMD's method of maintaining a pure fork and running hipify on every upstream commit doesn't seem very sustainable...

From Codeplay's blogs it seems they ported the tensor part of Eigen to SyCL. The Matrix part is not supported under SyCL. Tensorflow does have options to compile models to custom code (XLA), that part might not use Eigen.
