This got some attention on HN at the time (<a href="https://news.ycombinator.com/item?id=15520390">https://news.ycombinator.com/item?id=15520390</a>), but since then, I've improved the wording, layout, and page load speed, so I thought I'd submit it again.<p>A few of the numbers are out of date. L3 cache sizes seem to have increased pretty much in accordance with Moore's law (about 3 doublings in 6 years). L2 and L1 sizes not so much, but those caches tend to be per core, and we have more of those now. I believe the other numbers and general observations in the article hold up.
