PC shipments in Q2 grew 2.7% according to IDC, while Gartner estimates 1.4% increase; both firms agree this quarter's YoY growth was the best since Q1 2012
Gartner and IDC agree — Shipments of PCs are definitely growing, for the first time in six years.
Context & Ripple Effects
This quarter closes a long drought. Back in [[a:871335|Q2 2016, Gartner and IDC already saw US shipments growing while the worldwide market kept shrinking]], so the question was when the global line would cross zero. Six years later, both trackers independently put Q2 2018 in positive territory — IDC at 2.7%, Gartner at 1.4% — and agree it is the strongest year-over-year growth since Q1 2012.
What makes the datapoint credible rather than a rounding artifact is the dual-source agreement: two firms with different panel methodologies landing on the same directional call. The related coverage then shows the turn holding — Q2 2019 growth that both firms attribute to the Windows 10 refresh, followed by further gains into 2020.
First-order effects
- PC vendors exit a six-year streak of global year-over-year declines, giving Lenovo, HP and their rivals a demand backdrop they have not planned against since early 2012.
- Gartner and IDC's agreement removes the usual methodology dispute from the story — enterprises reading these trackers now treat the recovery as consensus rather than one firm's estimate.
Second-order effects
- The recovery converts into an upgrade-cycle narrative: by Q2 2019 both firms credit the Windows 10 refresh for continued growth, pulling commercial buyers off aging Windows 7 fleets and lifting average selling prices along with units.
- A growing PC market tightens component supply — memory, SSDs and panels — shifting pricing leverage toward suppliers as vendors compete for share in a market that no longer shrinks for them.
Third-order effects
- If the pattern holds, the PC industry's structure changes from secular decline to catalyst-driven cycles: the corpus shows growth persisting through 2019 on OS refreshes and spiking in 2020 on work-from-home demand, which both firms there explicitly frame as short-term — implying vendors must plan for event-led demand waves, not steady expansion.
- Sustained positive shipments also change the strategic math for diversification-hungry OEMs: a stabilizing core PC business funds bets on adjacent categories without the revenue base eroding underneath them.
The trend: The PC market is shifting from six years of structural contraction to a cyclical, catalyst-driven business — Windows refreshes and remote-work events replacing steady decline as the demand story.
