What Every Programmer Should Know About Memory?

Question

I am wondering how much of Ulrich Drepper\'s What Every Programmer Should Know About Memory from 2007 is still valid. Also I could not find a newer version than 1.0 or an er

Answer 1

From my quick glance-through it looks quite accurate. The one thing to notice, is the portion on the difference between "integrated" and "external" memory controllers. Ever since the release of the i7 line Intel CPUs are all integrated, and AMD has been using integrated memory controllers since the AMD64 chips were first released.

Since this article was written, not a whole lot has changed, speeds have gotten higher, the memory controllers have gotten much more intelligent (the i7 will delay writes to RAM until it feels like committing the changes), but not a whole lot has changed. At least not in any way that a software developer would care about.
