It's a good time for graphics programmers that want to understand how things are working under the hood. AMD and Intel provide AMAZING documentation for both their CPUs and GPUs. NVIDIA documentation is not as good but ok. It's pretty annoying that mobile GPU vendors are not following especially considering that these GPUs are harder to program but can yield gold from each watt consumed when properly understood. No, the "developer guides" are not interesting. Good luck to compete against NVIDIA software stack and their long waited first relevant mobile GPU. :p
Enjoy!
