There have been lots of other performance improvements, but I think they&#x27;re less visible than other stuff.  The CRC instruction that got added in SSE4.2 seems to get fairly wide use in hashes and stuff like btrfs.  I think <i>rdrand</i>, <i>aes</i>, and <i>clwb</i> are interesting ones as well.  I guess power consumption is kind of another visible gain.<p>I think the biggest visible change recently though, at least as a software engineer, is the continuously lowering cost, increasing availability of, memory.  I can literally store an entire project in memory and not have to worry about any network or disk bottleneck.
