Cloudflare abandons Intel Xeon processor and turns to AMD epyc

In the server processor market, AMD's goal this year is to occupy at least 10% of the market, which is not difficult, because the epyc7002 series of 7Nm zen2 architecture is constantly bringing customers to AMD. Cloudflare today announced that its 10th generation blade servers will be fully converted to AMD's epyc processor.

Cloudflare is a network service provider founded in 2009, which mainly provides CDN and DNS services. As of February 2020, it has built data centers in more than 200 cities in more than 90 countries, with 1 billion IP addresses flowing through their networks every day, processing 1100 HTTP requests per second, and 95% of global connections can be completed in 100 milliseconds.


In the past 10 years, cloudflare's servers have always been Intel Xeon, which is no problem. But in the 10th generation of blade servers, they gave up their old partners and turned to AMD's epyc processor. Moreover, this generation of servers has no Intel components, and there are no Intel components on CPU, motherboard, memory, storage and network interface, which is very rare in the industry.


They listed the configuration options of their blade servers in recent years. In 2015, they used e5-2630 V3, which is a dual 8-core, and then used the ninth generation blade server's dual platinum 6162, 2X24 core, 2x150w TDP.


The 10th generation blade server chose AMD's epyc 7642 processor, which is a 48 core 96 thread processor. They initially considered 64 core epyc, but after the test, they found that the performance improvement was not so high, and finally gave up the 64 core product.

Even so, the 48 core epyc 7642 can still test a single channel and achieve the previous two-way effect, and the cache, memory, PCIe channel number and other aspects are better. The TDP power consumption is 75W lower, equivalent to 25% lower per core TDP.


As for why AMD epyc processor was chosen, the test results published by them can illustrate the problem.


The detailed evaluation is as follows,However, this table summarizes the performance comparison between epyc 7642 and two-way platinum 6162. It can be seen that AMD leads by 27% in performance and 50% in performance

Of course, the most suspense is the price. Cloudflare didn't announce the specific price. It's not easy to say the estimated purchase price. It's a trade secret. However, according to the public offer, epyc 7642 is US $5885, Xeon platinum 6162 is US $3115, and two will cost US $6230.
