CDN helps with the page load/latency variable of Google' PageRank but won't equal AMP.
To get AMP-like speed you'd need: CDN, no render-blocking javascript, minimized image files, "lazy-loaded" assets & inlined CSS for "Above the Fold" content. On the server side you want to cache content with something like Varnish & send it over an "Edge" network like Akamai or Fastly. Ideally everything is served over HTTP2 or SPDY.

Doing all that replicates what AMP does.
