How Copper Graphics Card Plates Boost Performance
If you’re a gamer or a computer enthusiast, you probably already know that graphics cards are one of the most critical components of modern PCs. Not only do they render images and videos, but they also accelerate computations for machine learning, physics, and other demanding tasks. To achieve their high performance, graphics cards typically use a variety of advanced technologies, including dedicated processors, memory, power management, and cooling. However, one often overlooked but crucial aspect of graphics cards is their metal plates, especially those made of copper. In this blog post, we’ll explore how copper graphics card plates improve performance and why they matter for your gaming and computing experience.
What Are Graphics Card Plates?
Before we dive into the details of copper graphics card plates, let’s clarify what they are and what their roles are. Graphics card plates are the metal sheets that cover the front and back sides of graphics cards, protecting and enclosing their electronic components. These plates serve multiple purposes, such as:
– Providing structural support and rigidity to the card
– Enhancing thermal dissipation and reducing heat buildup
– Facilitating electromagnetic shielding and noise reduction
– Displaying branding, logos, or lighting effects
Graphics card plates come in various shapes, sizes, colors, and materials, depending on the design, brand, and model of the card. Some plates are machined from aluminum, steel, or plastic, while others are customized with coatings, engravings, or acrylic windows. However, regardless of their aesthetics, all graphics card plates share the function of enabling the card to function reliably and efficiently.
What Is Copper and Why Is It Used in Graphics Card Plates?
Copper is a chemical element with the symbol Cu and atomic number 29. It is a red-orange metal that has been known and used by humans for over 10,000 years, for its electrical conductivity, malleability, and resistance to corrosion. Copper is widely used today in many applications, from electrical wiring and plumbing to jewelry and sculpture. However, in the world of graphics cards, copper has a unique property that makes it stand out from other metals: its thermal conductivity.
Thermal conductivity is a measure of how well a material can transfer heat, from one place to another. The higher the thermal conductivity, the more efficiently the material can dissipate heat, and the lower its temperature can stay. Copper has one of the highest thermal conductivities among metals, second only to silver, with a value of around 400 W/(m·K), depending on its purity and temperature. This means that copper can quickly absorb and release heat, making it an ideal material for heat sinks, cooling pipes, and other heat dissipation components in graphics cards.
Thus, copper is used in graphics card plates, either as the main material or as a coating or plating layer, to enhance their thermal performance. Copper plates can help spread the heat generated by the graphics card’s processors, memory modules, and voltage regulators, across a larger surface, and transfer it to the environment more effectively. Copper plates can also help minimize hotspots, which are areas of the card where the temperature is higher than the average, and can lead to instability, degradation, or failure of the electronics. Moreover, copper plates can increase the stability and longevity of graphics cards, by reducing the thermal stress on their components and preventing them from overheating or throttling.
How Does Copper Affect the Design and Performance of Graphics Card Plates?
Now that we know that copper is a useful material for graphics card plates, let’s see how it affects their design and performance. Specifically, we can look at the following aspects:
– Geometry: The shape, size, and thickness of the copper plate can affect its surface area, contact with the components, and weight. For example, some copper plates may have fins or channels to increase their exposed area and airflow, while others may be flat or bent to fit the card’s layout or cooling system. Copper plates may also vary in thickness, from a few millimeters to a fraction of a millimeter, depending on the manufacturing method and the desired heat dissipation. Thicker copper plates can store more heat and release it later, but they may also add more weight and thickness to the card, which can limit its compatibility with certain cases or motherboards.
– Conductivity: The purity, composition, and processing of the copper plate can affect its thermal conductivity and electrical resistance. For example, pure copper has the highest thermal conductivity, but it may be too soft or expensive for mass production, so manufacturers may use alloyed copper, such as CuCrZr or CuNiSi, which can balance hardness, cost, and conductivity. Moreover, the surface of the copper plate may be polished, textured, or coated with other materials, such as nickel, silver, or diamond-like carbon, to enhance its thermal transfer and reduce its oxidation or contamination. However, these coatings may also reduce the copper’s conductivity slightly, due to their own properties.
– Compatibility: The copper plate must be compatible with the other components of the graphics card, such as the circuit board, the heat sink, and the fan (if any). For example, the copper plate must have holes or cutouts to allow the screws or clips to attach it to the card’s PCB, without creating short circuits or bending the connectors. The copper plate must also fit the heat sink, which is the device that transports the heat from the plate to the air or water cooling system. Moreover, the copper plate must not interfere with the fan, if one is present, which can cool the heat sink and promote the airflow over the card. Thus, the copper plate must be designed to balance its thermal performance with the overall cooling and acoustic profile of the card.
What Are Some Examples of Copper Graphics Card Plates?
To see how copper graphics card plates look and perform in real-life graphics cards, we can take some examples from popular brands and models. Here are three copper plate graphics cards that are currently available on the market:
