What are the major differences in the graphics engines between the 810 and 815/815E chipsets?
There are a few features that have been added to the 815 graphics engine from the 810. They are as follows:
1. Tri-Linear Filtering - animated scenes transition smoothly between the various texture maps.
2. Full color Specular (3D H/W acceleration) - better visual quality/accuracy of reflected lighting. Full range of color available for Specular hi-lighting.
3. ColorKey/Chroma Key (3D H/W acceleration) - can be globally enabled or disabled
4. The 815 is also capable of supporting an external AGP(4X) which is not supported by the 810 Chipset.
What are the differences between the 815 and the 815E?
815E is the platform that supports the ICH2 versus the ICH.
82815(GMCH) + 82801AA(ICH) = 815 Platform
82815(GMCH) + 82801BA(ICH2) = 815E Platform
Where can I obtain graphics drivers for the 815/815E chipset?
The latest Intel graphics drivers can be downloaded at your convenience.
Where can I obtain a complete list of collateral for developing an 815/815E chipset design?
See the technical documents for the E15/E15E chipsets.
For the 815/815E, what is the maximum memory for onboard direct AGP video?
The maximum memory size for a GPA (Graphics Performance Accelerator) card formerly AIMM (AGP In-Line Memory Module) card is 4MB (2 1Mx16, or 1 2Mx32). When using the GPA card (4MB), the driver may request up to 8MB of system memory, a total of 12MB. With the GPA card the driver may request up to 10MB of system memory.
Is it possible to run dual independent displays with the Intel 815/815E chipset?
No, the 815/815E GMCH contains a single graphics pipeline limiting its ability to produce multiple independent displays. The 815/815E does support multiple (same picture) displays through the use of an external PCI graphics device used in conjunction with either AGP or internal graphics of the GMCH. |
