The GPU is the physical circuitry that executes all your PC’s image rendering.

This type works better with a limited space and fewer CPU fans. Blowers or rear-exhaust follow the same concept but instead of dissipating heat through various openings, it only has one vent that expels warm air outside the CPU case.

This type of fan works well with a bigger CPU case with more air flow. Open-air coolers fan cool air in, spreads it throughout the heatsink and expels warm air out through the openings on the top and bottom of the graphics card.There are two ways fans are set up in GPUs: open-air and blower.Plastic fans mounted on the card’s external casing that mechanically blow hot air off the heat source and blow cool air in.A chemical compound used to fill microscopic gaps between the heat source (GPU) and the heatsink.Thermal paste / heat gel / thermal compound / heat paste At room temperature, thermal pads are smooth and firm but become soft and fill gaps when subjected to higher temperatures.Thermal pads also ensure that both the heatsink and other parts of the circuit are both in contact with each other.Strips of paraffin wax or silicone-based material on the underside of the heatsink to help with heat dissipation.As it cools, it turns back to liquid and is carried back to the copper plate. Some graphic card models hold water or ammonia that turns into vapor and travels away from the source of the heat.Heatsinks uses natural convection (passive heatsinks), forced air through blowers (active heatsinks), or a combination of both (hybrid heatsinks) to dissipate heat.One of the most common ways of dissipating heat away from the GPU by increasing the surface area and transferring heat away from the source using aluminum, copper coils, and fins.

Because it is replaceable, you can eventually upgrade your graphics card to prevent your PC from becoming obsolete. While different graphics card can have different performance, this type is often preferred on gaming builds or for creative production. Discrete graphics card – an external graphics card that can be inserted through your motherboard’s expansion slot or soldered directly.

However, it may struggle performing tasks for graphic-intensive games or professional media editing. An integrated graphics card can handle light and casual use such as browsing the web, watching streams, checking emails and social media, or light to medium games like Among Us or Undertale. You will mostly see this type on budget laptops or rigs.

Integrated graphics card – the system built into the processor that cannot be upgraded or replaced.

There are two types of graphics card used in modern computers today: From a technical standpoint, the GPU (graphics processing unit) is only a part of the graphics card, albeit a major component. It has its own processor, RAM (Random Access Memory), and other components. It is a smaller version of a computer motherboard (the main circuit board of a computer that serves as a bridge between major components such as the CPU (Central Processing Unit), memory, and peripherals).

Nvidia vs AMD – which brand suits your needs?Ī graphics card, otherwise known as a video card, is an expansion of your PC’s hardware, designed to render images to your display.

If you are looking for a graphics card, you might be asking the following questions: Nowadays, a graphics card is essential for many gamers and creative professionals for a smoother visual experience. This led to the development of the graphics card – hardware dedicated solely for processing and rendering images. The tech pioneer developed a modular architecture that allowed you to replace and upgrade different components of your PC individually. At the dawn of personal computing from 1982 to 1990, IBM brought a new standard to the industry.
