August 4, 2011 — Apple Inc.’s iPad has thus far thwarted competitive tablets in design efficiency, according to an IHS iSuppli Teardown Analysis of eight tablet models from IHS (NYSE: IHS). Major savings come from Apple’s control of chips like SDRAM and applications processors.
Apple is a vertically integrated manufacturer, creating much of the hardware and software in the iPad, points out Wayne Lam, senior analyst, competitive analysis, at IHS. Apple uses its own applications processor design in the iPad and iPad 2, Lam notes, while other tablets have processors sourced from Nvidia, Texas Instruments and Qualcomm.
Apple has limited the memory in the iPad 2, with only 512 megabytes (competitive designs use 1 gigabyte) of synchronous dynamic random access memory (SDRAM). This cuts nearly $14 from the iPad bill of materials (BOM) compared to the competition. Because Apple controls the hardware and software of the iPad, it can structure the operating system to use less memory.
Similiarly, the iPad battery is the thinnest of all competing tablet designs, yet has the largest capacity.
The table below presents an overview of the results of the dissection of eight tablet models. Note that the BOM figures accounts only for hardware and manufacturing costs and do not take into consideration other expenses such as software, licensing, royalties or other costs.

The IHS iSuppli Teardown Analysis Service also illustrates the trend toward multi-core processors in tablet designs, price points, and display sizes. Following the introduction of the Motorola Xoom in February and the iPad 2 in March, all new tablet designs within 2011 have included dual-core processors that deliver higher computing and graphical performance. In 2012 IHS expects to see this trend to continue with the introduction of tablets featuring quad-core processors for even more enhanced performance.
