The dominant CPU in the server market is without doubt Intel&#8217;s Xeon. The success of the Xeon family is largely rooted in its excellent single-threaded (or per core) performance at moderate power levels (70-95W). Combine this exceptional single-threaded performance with a decent core count and you get good performance in almost any kind of application. Economies of scale and the resulting price levels are also very important, but the server market has been more than willing to pay a little extra if the response times are lower and the energy bills moderate.<\/p><\/blockquote>\n<p>via <a href=\"http:\/\/www.anandtech.com\/show\/6757\/calxedas-arm-server-tested\">AnandTech | Calxeda&#8217;s ARM server tested<\/a>.<\/p>\n<p>As usual another thorough review from Anandtech.\u00a0 Below is another interesting architectural tidbit.<\/p>\n<p><a href=\"http:\/\/bucktownbell.com\/wp-content\/uploads\/2013\/03\/CalxedaSoc_575px.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-9511\" alt=\"CalxedaSoc_575px\" src=\"http:\/\/bucktownbell.com\/wp-content\/uploads\/2013\/03\/CalxedaSoc_575px.png\" width=\"600\" height=\"281\" srcset=\"http:\/\/bucktownbell.com\/wp-content\/uploads\/2013\/03\/CalxedaSoc_575px.png 600w, http:\/\/bucktownbell.com\/wp-content\/uploads\/2013\/03\/CalxedaSoc_575px-300x140.png 300w, http:\/\/bucktownbell.com\/wp-content\/uploads\/2013\/03\/CalxedaSoc_575px-500x234.png 500w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><\/p>\n<blockquote><p>Let\u2019s start with a familiar block on the SoC (black): the external I\/O controller.

PCIe connectivity cannot be used in this system, but Calxeda can make custom designs of the &#8220;motherboard&#8221; to let customers attach PCIe cards if requested.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>At first sight, the relatively low performance per core of ARM CPUs seems like a bad match for servers.
