Anger knows more about Intel and AMD microarchitecture than anyone else I'm aware of who's allowed to write about it freely. His guides, especially his microarchitecture and instruction timing documents, are superb resources that anyone serious about low-level optimization should have on hand.
I use his Microarchitecture regularly for ideas. Also Intel's Optimization manual and their IACA tool. But I always disassemble and A/B time things.
