A total of 68 million units were shipped this quarter, compared to 67 million units in the third quarter of 2018. Lenovo shipped the most units, with nearly a quarter of the market share, followed by HP and Dell. Brands with less than ten percent market share include Apple, Acer and Asus.

Some companies' sales grew compared to this time last year, like Lenovo, HP, Dell and Acer. Others were down compared to last year, including Apple and Asus. These numbers include desktop PCs and notebook PCs, but not Chromebooks or iPads.

One big challenge for PC manufacturers has been a shortage of Intel CPUs, but other vendors such as AMD and Qualcomm have moved to fill this gap. Low prices for RAM and SSDs have helped to buoy the industry, and the Windows 10 refresh cycle continues to drive new sales.

"Neither the Intel CPU shortage nor the US-China trade war had a significant impact on PC shipments in the third quarter of 2019," Mikako Kitagawa, senior principal research analyst at Gartner, wrote in the report. "The Intel CPU shortage has continued to ease, and US tariffs on China-built mobile PCs had a minimal impact on PC shipments as the date for the potential increase in tariffs was pushed out to December 2019."
