Pricing and Availability

Pricing - For as low as roughly ~$135 USD at the time of writing (Feb 2009).

Availability - Worldwide (assumed).

Volume Estimations

For the purposes of this teardown analysis, we have assumed a lifetime production volume of 3M units.

As a reminder, teardown volume production assumptions are primarily used for our cost analysis in terms of amortized NRE and tooling costs, especially for custom components specific to the model being analyzed (mechanical components especially). Unless assumed volumes are different by an order of magnitude, minor changes in volume (say 1 million vs. 2) rarely have a large net effect on our final analysis because of this.

What Is Not Included in our Cost Analysis

The total materials and manufacturing costs reported in this analysis reflect ONLY the direct materials cost (from component vendors and assorted EMS providers), AND manufacturing with basic test. Not included in this analysis are costs above and beyond the material manufacture of the core device itself - cost of intellectual property, royalties and licensing fees (those not already included into the per component price), software, software loading and test, shipping, logistics marketing and other channel costs including not only EMS provider and the OEM's margin, but that of other resellers. Our cost analysis is meant to focus on those costs incurred in the manufacture of the core device and exceptionally in some circumstances the packaging and literature as well.

Manufacturing Notes

OEM/ODM/EMS Relationships / Manufacturing

Gigabyte is a Taiwanese company with their own internal manufacturing facilities in Taiwan (Nan-Ping), but may have a relationship with, or possess their own manufacturing facilities in the People's Republic of China.

Country of Origin / Volume Assumptions

Based on the companies' structure, we are assuming the the unit was assembled in Taiwan. Furthermore, we have assumed that custom mechanicals (plastics, metals, etc.) were sourced in China.

Country of origin assumptions relate directly to the associated cost of manufacturing, where calculated by iSuppli. In the cases of 'finished' sub-assemblies, we do not calculate internal manufacturing costs, but rather assess the market price of the finished product in which case country of origin assumptions may or may not have a direct effect on pricing.

Remember also that labor rates are applied directly only to hand inserted components and systems in our bill of materials, and although regional assumptions do, these new rates do not have a direct effect on our modeled calculations of placement costs for automated SMD assembly lines. ""Auto" inserted components (such as SMT components) placement costs are calculated by an iSuppli algorithm which allocates a cost per component based on the size and pincount of the device. This calculation is affected by country or region of origin as well.

Design for Manufacturing / Device Complexity

The component count of this Gigabyte motherboard is 1554 vs. an overall average component count we see historically in desktop motherboards of about 1190 total components, making this device above average in component count.

Component counts have a direct bearing on the overall manufacturing cycle times and costs, and also can increase or decrease overall yields and re-work. Our calculations of manufacturing costs factor counts and more qualitative complexities in the design.

Note that manual labor has a much smaller effect on auto-insertion assembly lines (for the Main PCB, for example), where manufacturing costs are much more capital equipment intensive and driven by these investment costs.

Design Notes

The Gigabyte GA-MA790GP Motherboard design is based on the AMD 790GX chipset which features discrete North and Southbridge ICs. The Northbridge section is supported by DDR3 DRAM memory from Elpida (1 Gb). Furthermore, the I/O section features a Super I/O controller from iTE (IT8718F-S), a TI IEEE1394 host controller, an Ethernet controller and 7.1+2 audio codec from Realtek, as well as two Pericom MUX/DEMUX chips, one for HDMI, the other PCIe.

Here is a summary of the major components used in the Gigabyte GA-MA790GP Motherboard design:


  • SDRAM - Elpida - EDJ1116BASE-DJ-E - DDR3, 1Gb (64Mx16)



I/O & Interface

  • I/O Controller - iTE - IT8718F-S - Super I/O Device, LPC Interface
  • IEEE1394 Host Controller - Texas Instruments - TSB43AB23PDTG4 - Integrated 1394a-2000 OHCI PHY/Link-Layer
  • Ethernet Controller - Realtek - RTL8111C - PCI Express, Gigabit LAN
  • Codec - Realtek - ALC889A - Audio, 7.1+2 Channel, High Definition, w/ Content Protection
  • MUX/DEMUX - Pericom - PI3HDMI412FT-BZHE - 2:1, 4-Differential Channel, HDMI 1.3 Compliant
  • MUX/DEMUX - Pericom - PI2PCIE2412ZHE - 4-Differential Channel, PCIe Gen-II Compliant
