A bit meta, but for those who were not previously aware of Real World Tech, if you enjoyed this article then do dig into the archives. David Kanter does awesome writeups of (mostly) CPU and GPU architectures. I consider them a step beyond Anand Shimpi's write ups, the most recent of which was recently shared on HN, concerning Apple's Cyclone Microarchitecture [0]. They're published very infrequently, with the front page of RWT still having two articles from 2012 appearing.

Although it's not exactly relevant to the type of programming I do, I still find it useful to understand how modern processors actually work. At the very least, reading architecture articles helps me to understand exactly why certain processors are faster at specific tasks than others.

While I think it's great that David is being paid to write what he is good at, it's slightly disappointing to me that his long form writeups are going to be behind a pay wall at Microprocessor Report, which is covered in the recent article "Splitting my time between MPR and RWT" [1]. The submitted article is likely one of the few more in-depth articles he talked about being release in the next several months.
