ATI FireGL T2-128: A Cheap Starter Model
Compared to the high-end X2 model, the FireGL T2-128 appears considerably watered down. The number of geometry engines and pixel pipelines, for example, have been cut in half. That is also reflected in the number of chip transistors. The 75 million it has is 32 million less than on the X2. The T2 is positioned even below the Z1, X1 and X2 models. Hence, the product can only be recommended for entry-level users on a low budget.
The memory interface bus width is 128 bits. A clock speed of 300 MHz results in a bandwidth of 9.6 GB/s using DDR I memory (128 MB). Despite the "slimmed-down" core of the FGL9600 graphics chip (RV350W), ATI still manages to clock the card at 400 MHz. This is even 20 MHz higher than the X2. As with the mainstream Radeon 9600 model, the card does not require additional power.
The chip's main functions include:
- 2 parallel geometry engines (half as many as on the FireGL X2)
- 4 parallel pixel pipelines (half as many as on the FireGL X2)
- 128 bit floating-point precision
- two integrated RAMDACs with 400 MHz and 10 bits per channel
- max. eight light sources (hardware-accelerated)
- 16 textures per pass
- frame buffer support with 10 bits per channel
- 2X/4X/6X anti-aliasing modes
The FireGL T2-128 has a VGA connector (Sub-D 15pin) and a DVI-I jack, meaning that's it's not possible to configure a digital-only dual display. However, a single digital display can be set up in a dual display system if at least one screen is analog configured.
The market share of analog monitors - including flat screens - is still considerably higher than that of digital models.
