The iPad in Your Hand: As Fast as a Supercomputer of Yore
It's common wisdom that the computer you can hold in the palm of your hand today is as powerful as a computer from years ago that filled an entire room. — But now Jack Dongarra, one of the computer scientists who keeps track …
Context & Ripple Effects
Early coverage tested the iPad as a practical input device in a typing-speed trial, while a March 2011 assessment argued that its apps had not yet matched the hardware's promise. Dongarra's comparison puts a concrete scale on that hardware progress: the iPad is no longer merely a novel form factor, but a portable machine with compute capacity once associated with room-scale systems.
That matters because the iPad had already gained browser share and mobile-network usage, while Morgan Stanley analysis linked its sales to cannibalization of netbooks and other device categories. The constraint shifts from whether a tablet has enough raw capability toward whether software can make that capability useful.
First-order effects
- Apple gains a clearer performance argument for the iPad, strengthening its appeal against lower-end portable computers whose main advantage is general-purpose computing.
- Developers face a higher hardware baseline on which to build iPad software, even as criticism of the app ecosystem underscores that capacity alone does not produce compelling uses.
Second-order effects
- Netbook and low-end notebook makers face greater pressure where buyers value portability and everyday computing, a displacement pattern already identified in analysis of iPad sales.
- Software publishers and application developers become more consequential to iPad differentiation: the hardware comparison raises expectations that tablet apps should exploit more than a large touch screen.
Third-order effects
- If handheld performance continues to advance faster than software adaptation, competitive advantage in personal computing will move toward the platforms that pair efficient hardware with the strongest developer ecosystems.
- The tablet market is beginning to test whether compute capacity can be delivered in a consumption-first device without reproducing the full software model of a conventional PC.
The trend: Personal computing is shifting toward increasingly capable handheld hardware, with software ecosystems determining how much of that capacity becomes a substitute for PCs.
