card. PCI replaced the older ISA and VESA bus standards, and was itself superseded by the AGP standard for the main graphics card bus.

PCI Express® (PCIe™)

The successor standard to the PCI and AGP bus standards, with a significantly faster serial communications system, further opening up bandwidth for more communications between such peripherals as graphics cards and the computer’s CPU. PCIe cards can come in several physical configurations, the fastest currently being X16, which is typically used for graphic cards, and X1, typically used for other peripherals, such as separate multimedia cards.

Pipeline

In relation to computer graphic processors, refers to the number of separate arithmetic units available for rendering the output on a display. In general, more pipelines available on a graphical processor means there are more 3D rendering capabilities available, increasing overall 3D performance.

Pixel

All computer images are made up of tiny dots. Each individual dot is called a pixel, a word created from the term “picture element.” A pixel is the smallest indivisible unit of a digital image and can be only a single color. The size of the pixel depends on how the display resolution has been set. The smallest size a pixel can be is determined by the display’s dot pitch, which is measured in millimeters (mm).

Refresh Rate

Also referred to as “vertical refresh rate.” This is the rate at which a monitor or television can redraw the screen from top to bottom. NTSC television systems have a refresh rate of approximately 60 Hz whereas computer displays typically have refresh rates of 75 Hz or more. At refresh rates of 70 Hz and lower, screen flicker is often noticeable.

Rendering

Rendering refers to the final drawing stages where the 2D image that appears on a display is derived from its 3D descriptions. What appears on

X1550 SERIES specifications

The ATI Technologies X1550 series, released in 2006, is a key component of the Radeon line aimed at delivering affordable yet capable graphics performance for entry-level desktop and mobile computing. This graphics card series is based on the RV530 architecture, which was designed to offer strong visual quality and a variety of features suited for mainstream users.

One of the standout characteristics of the X1550 series is its support for DirectX 9.0c and Shader Model 3.0. This enables the card to handle a range of graphics-intensive applications and games that utilize advanced shading techniques, providing a richer visual experience. Additionally, the inclusion of OpenGL support empowers software development for applications in CAD and 3D rendering, making it versatile for both gamers and professional users alike.

The X1550 series caters to various segments with different configurations, including the X1550 Pro, X1550, and X1550 XT. Users can expect these cards to come equipped with 128MB to 512MB of GDDR2 or GDDR3 memory, depending on the model. The memory bandwidth and capacity enhance the ability to render graphics smoothly even at higher resolutions, ensuring that users can enjoy a decent gaming experience on budget.

Another significant feature of the X1550 series is its implementation of ATI’s Avivo technology, which enhances video playback and enables high-quality video encoding. Avivo includes features such as UVD (Unified Video Decoder), allowing for efficient video playback and improved power management, which is especially beneficial for laptops.

The card also supports ATI's CrossFire multi-GPU technology, which allows users to link multiple graphics cards for enhanced performance in gaming and graphic rendering tasks. This scalability ensures that even entry-level graphics solutions can meet the demands of more modern applications when combined with another compatible card.

In terms of connectivity, the X1550 series comes with various output options, including DVI and VGA outputs, ensuring compatibility with a wide array of monitors. Some models also support HDMI, enabling users to connect to high-definition displays for an expanded viewing experience.

Overall, the ATI Technologies X1550 series stands out as a cost-effective solution for users seeking decent graphics performance without the financial investment associated with higher-end models. Its balance of features, from support for modern graphics APIs to video playback technologies, makes it a noteworthy option for entry-level gaming and general multimedia tasks.
