Hennessy and Patterson

Ostensibly one of the most widely used books for studying computer architecture so I had a look, and... WTF? Possible future CPU designers are being fed with tripe like this?

Despite all the focus on MIPS and performance, it is suspiciously missing any real benchmarks of MIPS processors.

They have an interesting definition of a "desktop computer":

"Heineken and Pilsner" would be a better name for this book, as its authors appear to be as knowledgeable about real-world computer architecture as drunken fools.

simple instructions take less cache space

False. Your typical RISC instruction set wastes cache space for most instructions because all instructions have the same length, even for common cases where a shorter encoding is possible. Many common x86 instructions occupy only 1-2 bytes; equivalent RISCs use 4 bytes for nearly everything.
