AMD continues to chase down Intel in the chip race. While Intel still dominates the global market share, AMD made significant gains in Q4 2019. Patrick Moorhead, the president and founder of Moor Insights & Strategy shared some figures from PR agency on Twitter (via PC Gamer). They show solid growth by AMD in mobile as well as a noticeable bump in desktop.

In Q4 of 2019, AMD saw a 1.5 percent increase in mobile (excluding IoT). That closed out a year in which AMD grew 4 percent overall in that space. AMD's mobile market share is up to 16.2 percent (excluding IoT), according to the figures from PR Agency.

AMD's desktop market share saw a smaller increase of 0.3 percent in Q4 2019 (excluding IoT) but is doing well at 18.3 percent. AMD's PC market share increased 2.4 percent in 2019 (excluding IoT).

AMD's PR agency just shared with me Q4 Mercury Research unit market share numbers for AMD excluding consoles and IoT. So I thought I'd share with you. Keep in mind these are unit share, not dollar share. pic.twitter.com/glFi0WP7F0 — Patrick Moorhead (@PatrickMoorhead) February 5, 2020

While AMD still trails Intel by a vast margin across the board, AMD continues to trend upward and have success in key areas.

Several factors affect people's buying habits, but at least some of the changes in Q4 of 2019 were likely influenced by the severe CPU shortage Intel faced in the second half of 2019.
