According to Mercury Research, AMD gained 5.8 per cent unit share in desktops, 3.8 per cent in laptops, and 5.8 per cent in servers. Regarding revenue share, AMD gained 4.1 per cent in desktops, 5.1 per cent in notebooks, and 1.7 per cent in servers.
While Mercury failed to mention AMD’s rivals by name, the global PC industry only has one other major CPU supplier, Intel, which has a significant stake in all the market segments.
While Intel and AMD make x86 processors for PCs, Qualcomm offers Arm-based SoCs for Windows notebooks, but its market share is minuscule by comparison.
It is fair to assume that most of AMD's gains came at Intel's expense.
