3. RAMDAC
RAMDAC (Random Access Memory Digital-to-Analog Converter) is an important part of a graphics card that functions to convert digital signals into analog signals. This is especially important when using a CRT (Cathode Ray Tube) monitor.
RAMDAC is in charge of converting the digital signal received from the graphics card into an analog signal that can be understood by the CRT monitor. This process is crucial because CRT monitors use electron beams directed at cathode tubes to display images on the screen. Analog signals are required for the image to display properly.
Difference Between Analog and Digital RAMDAC
RAMDAC Analog
Analog RAMDACs were commonly used in the early days of graphics card development. They convert digital signals into analog signals directly so that the images displayed on CRT screens are of the highest quality.
RAMDAC Digital
Along with the advancement of technology, LCD (Liquid Crystal Display) monitors are starting to be widely used. LCD monitors do not require an analog converter because they can receive digital signals directly. Therefore, digital RAMDAC is no longer necessary in modern systems that use flat monitors.
With the advent of flat-screen monitors such as LCDs and LEDs, RAMDAC technology has become less relevant. This modern monitor can instantly receive digital signals.
Types of Graphics Cards
1. Integrated Graphics Card vs. External
In the world of computers, choosing between an integrated graphics card and an external graphics card is essential, especially for users with special needs such as gaming, graphic design, or everyday use. Here is an analysis of the advantages and disadvantages of each type of graphics card, as well as tips for choosing the right one according to your needs.
Integrated Graphics Card
An integrated graphics card is a GPU that is attached directly to a CPU or motherboard. These GPUs share resources with the system’s RAM and are designed for everyday use that doesn’t require heavy graphics processing.
Pros:
- There is no need to purchase additional components.
- Uses less power than external graphics cards.
- Suitable for laptops or small PCs as it does not require additional space.
Cons:
- Not suitable for heavy tasks such as gaming or graphics rendering.
- Using resources from RAM can reduce the overall performance of the system.
- It does not support the latest technologies such as ray tracing or gaming with high refresh rates.
Examples of proper use for integrated graphics cards are office work such as using Microsoft Office or browsing the internet, as well as for light media such as video streaming or simple photo editing.
External Graphics Card (Discrete Graphics Card)
An external graphics card is a standalone device that is purpose-built to handle heavy graphics tasks. These GPUs have their memory (VRAM) and are designed to provide high performance.
Pros:
- Perfect for gaming, 3D rendering, or high-resolution video editing.
- It supports technologies such as ray tracing, AI-enhanced rendering, and high refresh rates.
- It has its VRAM so it doesn’t put a strain on the RAM on the system.
Cons:
- Higher price compared to integrated GPUs.
- Requires a powerful PSU (Power Supply Unit).
- Requires additional space inside the PC case, not suitable for small devices.
Examples of external graphics card use include playing AAA quality games at high resolutions and stable frame rates, using design and rendering software such as Blender or Adobe Premiere Pro, as well as in content production such as 4K video editing or 3D animation.
2. Graphics Cards for Gaming
When choosing a graphics card for gaming, there are several important specifications that need to be considered in order to optimize the gaming experience. Here is an explanation of the specifications to look out for, recommendations for popular brands and models, as well as additional factors such as resolution, refresh rate, and DirectX/OpenGL support.
