AMD's marketshare in the mobile market is even higher, thanks to the good performance of its APUs the company now holds 19.9 percent of the mobile market, which is AMD's highest mobile marketshare figure ever. AMD's total x86 client marketshare is now 19.7 percent, the highest since 2013.
If you think that's low after the success of the Ryzen series, wait until you hear about the server market. Purchases for servers are made pretty conservative so this is a very slow-moving market. Despite the benefits of the latest EPYC server CPUs from AMD, the company still holds only 5.8 percent of the server market. AMD claims the Mercury Research figures should not be compared to the figures from IDC, which AMD uses for its server share projections.
AMD bases its server share projections on IDC's forecasts but only accounts for the single- and dual-socket market, which eliminates four-socket (and beyond) servers, networking infrastructure and Xeon D's (edge). As such, Mercury's numbers differ from the numbers cited by AMD, which predict a higher market share. Here is AMD's comment on the matter: "Mercury Research captures all x86 server class processors in their server unit estimate, regardless of device (server, network or storage), whereas the estimated 1P [single-socket] and 2P [two-socket] TAM [Total Addressable Market] provided by IDC only includes traditional servers."Via: Tom's Hardware
