The Samsung GALAXY Note 4 hit the Taiwan market on Oct. 9 and TechInsights has completed disassembling the handset and providing a cost analysis.
The processor from the disassembled GALAXY Note 4 is Samsung’s Exynos 5433 and not Qualcomm’s Snapdragon 805. This seems to indicate that Samsung has returned to what it did with the GALAXY Note 2, which employed the company’s Exynos 4412 rather than a third party processor.
Unlike the GALAXY Alpha, which is equipped with Intel’s XMM 7260 baseband modem, no signs of Intel’s chips could be found on the GALAXY Note 4‘s printed circuit board (PCB).
As for baseband, Samsung adopted the Shannon 303, while various other components, including the power management chip, RF transceiver, image processor, and NFC controller, are all from Samsung’s own product lines.
The device’s Digital barometric pressure sensor is Bosh Sensortec’s BMP180; the 3-Aixs is Yamaha’s YAS532B. The audio hub CODEC w/voice processor DSP is Wolfson’s WM5110E, the same as the one used in the GALAXY Alpha, while the heartbeat sensor appears to be an unknown model from Analog Devices.
The other chips seen on the PCB are from Maxim, Avago, Broadcom and Silicon Image.
As for the S Pen, the stylus is Walcom’s W9012 model. The GALAXY Note 3 used Wacom’s previous W9010 model.
The teardown performed by TechInsights could not confirm the chips and brands of the Wi-Fi/Bluetooth/ANT+ components.
It’s worth noting that Qualcomm’s components are hardly seen on the “Exynos chip” edition of the Samsung GALAXY Note 4, which is unlike the case with the previous Note 3 (Qualcomm edition), where the only Samsung parts that showed up are its NAND Flash and SDRAM components. The situation is apparently the same for Samsung’s GALAXY Alpha model.
In terms of the GALAXY Note 4’s overall cost, the TechInsights report concluded it could be $US 267, which is noticeably higher than iPhone 6 Plus’ $US 245.2.
The cost difference between the two models is mainly due to their panels, cameras, processors and NAND Flash. The biggest difference lies in the display – Samsung uses a 5.7-inch Super AMOLED display (2560×1440), while iPhone 6 Plus has a 5.5-inch display (1920×1080). The Apple handset outperforms Samsung in both the non-electronic parts and BB+XCR.
According to TechInsights, one main thing that needs to be kept in mind regarding its cost analysis is that it is only based on components and assemblage without including the R&D and other authorization costs.
