Cloudflare CDN Upgrades to AMD EPYC 7713 64-Core, 128 Thread CPU at Edge Locations
Cloudflare CDN which many of us use, including myself, has written a blog post about launching of their 11th generation server fleet, AMD EPYC 7713 64 Core Processor with 128 Threads which have max boost of 3.675 GHz and 384GB DDR4-3200 RAM
Previously they used: AMD EPYC 7642 48-Core Processor at 3.3 GHz
In production testing, we found that the 64 core EPYC 7713 gave us around a 29% performance boost over the incumbent, whilst having similar power consumption and thermal properties.
Users using Cloudflare Workers / serverless can see some benefit in loading/executing the javascript worker bit faster.
server enthusiasts should definitely read the above blog post. It's in-detail how they tested the various CPUs!

This means that they can cram 29% more users on same amount of machines. Benefit for users is definitely not a goal in this case
Couple of years ago when they upgraded from Intel to more faster, modern AMD EPYC server we saw the TTFB slide down and pages-loading faster. Earlier lots of users complained about enabling cloudflare CDN and their sites adding extra TTFB due to many factors, among them was Intel's old servers (2x 12 core Intel Xeon Silver 4116 2.1Ghz) to the newer one (2x 24 core Intel 1.9Ghz), which later help to reduce TTFB when they upgraded to AMD EPYC 7642.
So indeed they can put more users per server, as sites on internet have increased to zillions and so is the use of cloudflare they needed an upgrade to boost performance.
It also means they can filter more layer 7 attacks? Definitely a benefit to the customer
