The deciding factor in Baidu choosing EPYC seems to be the performance offered by the platform when configured for single-socket use.
"By offering outstanding performance in single-processor systems, the AMD EPYC platform provides flexibility and high-performance in our datacenter, which allows Baidu to deliver more efficient services to our customers," said Liu Chao, senior director, Baidu System Technologies Department. "Baidu's mission is to make a complex world simpler through technology, and we are constantly looking to discover and apply the latest cutting-edge technologies, innovations, and solutions to business. AMD EPYC processors provide Baidu with a new level of energy efficient and powerful computing capability."
AMD offers what it calls a "no compromise" single-socket platform, with no arbitrary limitations set on i/O, or memory bandwith and performance. This allows customers to make a no compromise choice for underutilized servers, and benefit from lower power consumption and lower capital expenditure.

"Baidu is a long-recognized pioneer in datacenter innovations, and with their adoption of AMD EPYC they continue down that path by leveraging our single-socket innovations to power their ABC strategy," said Scott Aylor, corporate vice president, and general manager, AMD Enterprise Solutions. "It is a thrilling experience to work side-by- side with Baidu to explore the capabilities of AMD EPYC and maximize its application across their customers' workloads."
Each EPYC processor package can support up to 2TB of DDR4 RAM over eight channels, and has 128 PCIe lanes, which means that the platform has more than two-and-a-half times the I/O density of a processor such as Intel's Xeon SP Series.
