IDC in its own preliminary results, on the other hand, claims a growth of 4.7 percent . Lenovo kept the top spot in Q2 2019 with the fastest growing growth and the largest share gain among the top sellers, noted both search companies.

According to Gartner, the global PC shipments totalled 63 million units in the Q2 of 2019up from 62 million units at the Q2 of 2018, whereas IDC stated the overall deliveries were 64.9 million units, up from 61.9 million units last year.

Gartner says that the top three sellers – Lenovo, HP, and Dell – accounted for 64.1 percent of global PC shipments in the Q2 of 2019, compared with 60.7 percent of shipments in the Q2 of 2018. The three sellers claimed 66.1 percent market share in IDC’s reportup from 64.4 per cent last year.

Gartner and IDC, however, painted widely contrasting picture for Apple’s Mac desktop shipments in the second quarter (Q2) of 2019. IDC said Apple prices were up 9.6 percent from an estimated 3.7 million units shipped over the exact same period in 2018 that puts the iPhone manufacturer in fifth position with 6 per cent share.

Whereas Gartner said Apple sent 3.7 million Mac units in 2nd quarter, down 0.2 percent year-over-year. According to Gartner, Apple obtained 5.9 percentage of their worldwide PC market – down from 6 percent in 2018.

“Worldwide PC shipments expansion was driven by demand from the Windows 10 refresh in the business market from the Q2 of 2019. Desktop PC growth was strong, which offset a decrease in cellular PC shipments,” Mikako Kitagawa, Senior Principal Analyst at Gartner, said in a statement.

“Provide for Intel’s processors improved markedly during the quarter, allowing most PC vendors to fulfill aged orders while also shipping a wholesome supply of new PCs into the stations,” said Jitesh Ubrani, research manager for IDC’s Mobile Device Trackers, in a statement. “Additionally, the threat of increased tariffs led some PC manufacturers to send a surplus of desktops and notebooks, thereby artificially propping up the PC market during the next quarter.”

The continuing trade dispute, and the possible imposition of tariffs, adds doubt to the near-term outlook for PC demand.

The top three vendors continued to gain share in the PC market benefiting from economies of scale. Intel’s CPU supply shortage in the first half of this year accelerated this trend.

“While the US-China commerce war failed to impact the PC marketplace in the Q2 of 2019, another phase of tariffs might have a significant impact.

“Most notebooks and tablets are manufactured in China and earnings of these devices in the united states could face substantial price increases when the tariffs are levied and sellers do not take quick action to respond,” added Kitagawa.
