The HSPA+ version of new Samsung Galaxy S4 smartphone costs Rs.12,688.17 ($236) for materials, up 15 per cent from its predecessor Galaxy S III, according to a virtual teardown by IHS iSuppli.

The HSPA+ S4 with 16GB of NAND flash memory costs Rs.13,118.28 ($244) when the Rs.456.99 ($8.50) manufacturing cost is added in. The bill of material (BOM) of the HSPA+ version of the S4 is Rs.1,634.41 ($30.40) higher than for the equivalent version of the Galaxy S III.

The S4 employs a full-HD active-matrix organic light-emitting diode (AMOLED) display from Samsung Display with a pixel format of 1,920X1,080. This compares to the 1,280X720 WXGA resolution display in the S III. The S4’s HD display and touchscreen subsystem is estimated to carry a cost of Rs.4,032.26 ($75), up from Rs.3,494.62 ($65) for the S III.

"This represents the single largest area of cost increase for the S4 compared to the S III."

The HSPA+ version of the Galaxy S4 employs an Exynos 5 Octa -- an eight-core chip --manufactured with Samsung’s own 28-nm process. This compares to the quad-core Exynos apps processor in the Galaxy S III. The cost of the Galaxy S4’s processor is estimated at Rs.1,612.90 ($30). compared to Rs.940.86 ($17.50) for the chip in the Galaxy S III.

The Galaxy S4’s eight-core Exynos processor uses ARM’s big.LITTLE microprocessor architecture. The architecture employs a hybrid approach generally referred to as heterogeneous computing, whereby two central processing units (CPUs) -- a quad-core Cortex-A15 CPU and a quad-core Cortex-A7 CPU -- are integrated into the same chip.

The 4G LTE version of the Galaxy S4 uses employs a Qualcomm Snapdragon 600, a quad-core apps processor and LTE radio solution.

The humidity and temperature sensor as well as the IR gesture sensor are new in the Galaxy S4 compared to the Galaxy S III. Because of these new capabilities, the user interface and sensor subsystem of the Galaxy S4 carries an estimated cost of Rs.860.22 ($16), up from Rs.682.80 ($12.70) in the Galaxy S III.

Although the LTE version of the Galaxy S4 employs a more advanced mobile radio than the HSPA+ version, its total BOM cost is slightly lower at Rs.12,526.88 ($233).

The LTE Galaxy S4’s wireless section costs Rs.1,344.09 ($25), higher than the Rs.860.22 ($16) for the HSPA+, because it supports the new 4G LTE air interface standard as well as up to six global LTE bands.

However, the LTE version keeps expenditures down by using the Qualcomm Snapdragon 600 solution, which costs Rs.1,075.27 ($20).

Samsung accounts for at least Rs.8,010.75 ($149) worth of component content in the HSPA+ version of the Galaxy S4, representing 63 per cent of the total BOM.

“Among the upgrades are a larger, full high-definition (HD) display; a beefed-up Samsung processor; and a wealth of new sensors that set a record high for the number of such devices in a smartphone design. And despite the larger display and other changes, the Galaxy S4 has roughly the same width and the same ease of handling as the Galaxy S III,” said Vincent Leung, senior analyst for cost benchmarking at IHS.
