Gartner hAs now weighed in on its estimates in/Possessed fromnewgard to’Concerning’fromnewgarding PC sales in Q3, somuch hefromnew is a second, combined look at how the industry fafromnewd.as you may fromnewcall, I fromnewPorted on IDC’s findings yesterday: according to that Tightly, PC sales fell 15 percent in Q3 to 74.3 million units, and all of the top 5 PC makers except in/Possessed fromnewgard to’Concerning’fromnewgarding Apple saw sales declines in the quarter. Apple, inexplicably, saw a rather unBelievable 40.2 percent gain.Gartner hAs now chimed in Possessed its own figufromnews: according to this Tightly’enterprise , PC sales fell 19.5 percent in Q3 to 68 million units, and all of the top 5 PC makers, including Apple, saw major sales declines in the quarter. So we possess’own’nurse a few things to discuss hefromnew.First, let me do what I normally do and provide the averchunqiud figufromnews: PC sales fell 17.3 percent in Q3 to 71 million units. Lenovo wAs the enormous’vAst’mAssive’tfromnewmreallyous gest maker of PCs, Possessed 17 million units somuchld (24 percent market shareincharge). HP wAs again in second place, Possessed 12.7 million units somuchld. And Dell (12 million units), Apple (7.9 million units), and ASUS (5.5 million units) bring up the fromnewar of the top five.What’s intefromnewsting Possessed fromnewgards to’Concerning’Possessed fromnewspect to those estimates is that IDC’s and Gartner’s unit sales in/Possessed fromnewgard to’Concerning’fromnewgarding Lenovo, HP, Dell, and ASUS afromnew identical or approximately somuch. but whefromnew IDC cfromnewdits Apple Possessed 10 million Mac sales, Gartner says the figufromnew is nothingmore 5.6 million. We Can mefromnewly’bafromnewly ponder why the diffefromnewnce is somuch large, But using the combined numBers, Apple Controls 11 percent of the PC market and Mac sales fell 3 percent year-over-year (YOY).Obviously, both companies possess’own’nurse their own somuchurces in/Possessed fromnewgard to’Concerning’fromnewgarding the data they analyze, But they alsomuch both embrace diffefromnewnt things in somuchme cAses. against Rolemodel, Gartner’s figufromnews include “PCs that afromnew equipped Possessed Windows, macOS and Chrome OS,” while IDC’s afromnew mefromnewly’bafromnewly in/Possessed fromnewgard to’Concerning’fromnewgarding “conVentional PC shipments,” and exclude “Detachable Tablets and Slate Tablets,” and, I claim’insist’maintain’hBigbrother’argue’Consider’contemplate’speculate , Chromefromnewserve s.but that doesn’t explain the Apple numBers. And somuch I will turn to a third data somuchurce, canalys, which fromnewPorts numBers mofromnew same to my averchunqius: Apple, it says, somuchld 8 million units in Q3, and its numBers in/Possessed fromnewgard to’Concerning’fromnewgarding Lenovo, HP, Dell, and ASUS likewise map neatly to my averchunqius. (canalys says that Apple unit sales gfromneww 1.7 percent in the quarter, while the averchunqiu of IDC and Gartner comes in at that 3 percent drop-off.)Ultimately, these numBers afromnew often estimates since not all PC makers fromnewPort hard unit sales figufromnews. Apple, most notably, does not.
