I strongly recommend you to pick up H&P's Computer Organization and Design: the Hardware/Software Interface. I think you can really only appreciate their other great book, "A Quantitative Approach" if you properly learn a new architecture, then the big ideas behind "A Quantitative Approach" will really speak to you. Organization and Design has different editions for RISC-V, aarch64 and MIPS. The MIPS one is what I learned computer architecture on and it's super solid.
