Last week we showed you iFixit's teardown of the Nexus 7 and their estimate of $184 for the materials to build Google's new tablet.  Well today we bring you some pics from UBMTechInsight's turn at the teardown with a complete list of components below and some 'insight' into what companies received design wins to build the tab. 

At the center of the device of course is the Nvidia Tegra 3 processor, which can be seen below in diffusion layer.  The Tegra 3 has won a boatload of design wins over the past months powering everything from Asus' own Transformer Prime to Microsoft's upcoming 'Surface' ARM variant among others.  It's a good choice too...featuring 4 main cores plus a 5th core for low power applications.  All that and a 12 core GeForce GPU to handle graphics tasks.   

No, this is not a bird's eye view of Manhattan, it's the Nvidia Tegra 3 Processor shown in diffusion layer

Another winner in the Nexus 7 contract contest is Hynix, which not only is making the 1280x800 display for the tablet but also the 2GB DDR3 SDRAM memory modules on the main board.  Broadcom also has multiple wins with their BCM4330 802.11n Bluetooth transceiver and BCM4751 integrated GPS receiver both part of the Nexus 7 internals.  Overall the component list you see below is a worldwide effort with such well known names as Kingston, Texas Instruments and Fairchild all contributing to the $199 tablet.

Key Component Listing
NVIDIA Tegra 3 Quad-core mobile applications processor
Kingston KE44B026BN/8GB 8GB Memory Module
Realtek (RMC) ALC5642 Audio CODEC + Headphone Amplifier
Maxim MAX77612A Power Management IC
Texas Instruments TPS63020 Buck-Boost Converter
Fairchild FDMC6675BZ P-Channel Power MOSFET
Texas Instruments SN75LVDS83B LVDS Display SERDES
ELAN Microelectronics eKTF3624BWS Controller for Resistive Touchscreen
ELAN Microelectronics eKTH1036BWS Controller for the Resistive Touchscreen
Broadcom BCM4751 Integrated Monolithic GPS Receiver
InvenSense MPU-6050 Six-Axis (Gyro + Accelerometer) MEMS Device
AzureWave AW-NH665 802.11n WiFi / Bluetooth / FM Radio module
NXP Semiconductor PN65 Secure NFC Module

So what's the final tally of the Nexus 7's cost?  Well we'll have to wait for iSuppli's manufacturing cost breakdown that they're known to do on all tech devices but with estimated costs of $184 for components alone and the additional costs of manufacturing, marketing and distribution it's fair to say that Google isn't making a dime on the 8GB version and probably only a modest profit on the 16GB variant.   If the Nexus 7 is the 'razor'...Google is hoping that you buy lots of 'blades' in their Google Play store.
