This chart from IDC shows the top five worldwide PC vendors according to units shipped for the third quarter of this year. PCs include desktops, mini notebooks and other portable PCs. They do not include handhelds or tablets without hardwired keyboards.

IDC's press release states that worldwide PC shipments totaled 78.5 million units in the third quarter of 2014, a year-on-year decline of -1.7%, but a sizable improvement over the forecast of -4.1%.

While the other four vendors showed growth, Dell was the only top five vendor to see a decline of 0.7%. Still, Dell has grown 9.7% on the year. Apple moved into the #5 position, slightly overtaking ASUS. The company's steady growth, along with recent price cuts and improved demand in mature markets, has helped it to consistently outgrow the market. Lenovo has been holding a comfortable lead as the top PC supplier, hitting another record volume of 15.7 million units.

Overall, Lenovo and HP have remained at the top of the group. Dell has maintained the middle tier while Acer and Apple have brought up the third tier.
