Intel Extreme Graphics 2 Specs
- Intel includes the Intel Extreme Graphics 2 chip on its Intel 852 / 855 chipsets, specifically the GM, GME and GMV varieties that support laptop computers with Celeron, Centrino and Pentium 4 microprocessors. The Intel Extreme Graphics 2 is compatible with 2D and 3D application programming interfaces (APIs), specifically Microsoft's DirectX 8 API. For output compatibility, the graphics chip provides an accelerated graphics port (AGP) digital display card for connecting to TVs and a dual digital video output (DVO) port for connecting to flat-panel monitors. As a supporter of multiple displays, the Intel Extreme Graphics 2 can run graphics simultaneously on two separate display types. These display types include TVs, cathode-ray tube (CRT) monitors, digital visual interfaces (DVIs) and low-voltage differential signaling (LVDS) systems.
- The internal path of a graphics chip refers to how many lanes of data traffic that chip can accommodate. The Intel Extreme Graphics 2 has a 256-bit internal path, which allows the chip to provide up to four textures per pixel on a single pass or data transmission. A higher amount of textures per pixel correlates to more realistic atmospheric effects and surface details.
- The Intel Extreme Graphics 2 has a digital-to-analog converter (DAC) with a frequency, or clock speed, of 350MHz. This specification indicates how frequently a graphics chip generates electronic pulses for converting computer binary code into viewable, analog signals. Using its 350MHz DAC, the Intel Extreme Graphics 2 can support the Quantum Extended Graphics Array (QXGA) resolution. QXGA entails a maximum display resolution of 2048 horizontal lines of pixels by 1536 vertical lines of pixels.
- For sharing system memory with a computer's graphics display, applications and operating system, the Intel Extreme Graphics 2 utilizes Dynamic Video Memory Technology (DVMT) 2.0. This technology eliminates the need for dedicated or stand-alone graphics memory, while also preventing the graphics chip from locking down or over-using system memory, which can have a negative impact on a computer's performance. Using DVMT 2.0, the Intel Extreme Graphics 2 can share up to 64MB of system memory.
- The clock rate and shader speed of the Intel Extreme Graphics 2 are linked, with both being capable of 133 MHz. While clock rate refers to how frequently the Extreme Graphics 2, as a whole, generates electronic pulses for executing commands, shader speed refers to how frequently the graphics chip's shaders, or individual processing cores, generate electronic pulses for executing commands. With both specifications, higher speeds correlate to faster graphics processing.
