In Q2, IDC estimates global PC shipments grew 4.7% to 64.9M units; Gartner estimates 1.5% growth to 63M units; both say Windows 10 refresh contributed to gain

Steven Sinofsky / @stevesi : 6 yrs ago, PC sales were 76M units for Q2 (10 yrs ago it was 90M) compared to 63M. When IDC grows more than Gartner it is mostly due to Chromebook growth. https://twitter.com/... @manan : old enough to remember how tech journalists wrote PC is dead on their PCs 6 years ago saying the iPad killed the PC.

Context & Ripple Effects
This quarter extends a fragile recovery: Q2 2018 was the best growth since Q1 2012 per IDC and Gartner's shared read last year, but Q3 2018 went essentially flat, so Q2 2019's gains — 4.7% at IDC, 1.5% at Gartner — are the second consecutive positive quarter rather than a breakout. Both firms point to the same engine: Windows 10 refresh migrations ahead of the Windows 7 sunset.
The disagreement is as notable as the growth. The firms count different things as a PC, and it shows at the edges: IDC puts Mac shipments up 9.6% worldwide while Gartner has them down 0.2%. Separately, Gartner is flagging that US tariffs on China could significantly drive up laptop prices — a demand-side risk layered on top of a refresh-cycle tailwind.
First-order effects
- Commercial buyers accelerating Windows 10 migrations are doing the heavy lifting this quarter, and with Lenovo holding roughly 25% share per IDC, the refresh skews gains toward the top of the vendor table while smaller players fight for replacement volume.
- Gartner's tariff warning lands directly on laptop pricing: if duties raise costs, vendors must choose between margin compression and price hikes on the very category driving the refresh.
Second-order effects
- Tariff-driven price pressure creates its own pull-forward: buyers who might have waited could accelerate purchases to beat increases, inflating near-term shipment numbers the way the Windows 7 deadline already is — a risk both firms' Q3 readings will have to untangle.
- The widening definitional split — visible in the Mac figures diverging by nearly ten points — pressures vendors and investors to pick which tracker to benchmark against, since the same quarter reads as solid growth or a modest uptick depending on the source.
Third-order effects
- If growth keeps leaning on OS migrations and tariff timing rather than organic demand, the PC market's recovery is a series of deadline-driven bumps, and the flat Q3 2018 reading is the shape of what follows once the refresh pool empties.
- Sustained divergence between IDC and Gartner methodologies — what counts as a PC, how Macs are tallied — pushes the industry toward a world where 'the PC market' has no single number, complicating vendor targets and procurement benchmarks alike.
The trend: PC shipment growth is increasingly event-driven — OS end-of-life refreshes and tariff timing — rather than a return to structural expansion, with the two trackers' definitional split widening as the market's composition shifts.
