The NVIDIA GeForce RTX 2080 Super was a powerhouse of a graphics card when it launched, and it remains a capable performer even today. One of the key specifications that determines a GPU’s performance is its clock speed, measured in GHz (Gigahertz). Understanding the clock speeds of the RTX 2080 Super, and what they mean, is crucial for anyone looking to buy a used card or simply understand its capabilities.
What Is Clock Speed And Why Does It Matter?
Clock speed, in the context of a GPU, refers to the rate at which the GPU’s core and memory operate. It’s essentially the heartbeat of the GPU, dictating how quickly it can process instructions and perform calculations. A higher clock speed generally translates to faster performance, as the GPU can execute more operations per second.
Think of it like this: imagine two identical assembly lines building cars. If one assembly line operates at a faster pace (higher clock speed), it can produce more cars in the same amount of time. Similarly, a GPU with a higher clock speed can render more frames per second (FPS) in a game or complete rendering tasks faster.
However, clock speed isn’t the only factor determining GPU performance. Other specifications, such as the number of CUDA cores, memory bandwidth, and architecture, also play significant roles. It’s a combination of all these factors that ultimately determines how well a GPU performs in real-world applications.
The Specified Clock Speeds Of The RTX 2080 Super
NVIDIA officially specified two key clock speeds for the GeForce RTX 2080 Super: the Base Clock and the Boost Clock.
- The Base Clock is the minimum guaranteed clock speed that the GPU will operate at under normal conditions.
- The Boost Clock is the maximum clock speed that the GPU will dynamically reach when thermal headroom and power limits allow.
The official specifications for the RTX 2080 Super are as follows:
- Base Clock: 1650 MHz (1.65 GHz)
- Boost Clock: 1815 MHz (1.815 GHz)
It’s important to note that the boost clock is not a fixed value. The actual boost clock that the GPU achieves in practice will vary depending on the workload, temperature, power consumption, and the specific implementation of the card by different manufacturers.
Factors Affecting Boost Clock Performance
Several factors can influence the actual boost clock speed achieved by an RTX 2080 Super card:
-
Thermal Management: The GPU will prioritize staying within its thermal limits. If the GPU gets too hot, it will reduce its clock speed to cool down, preventing damage. A good cooling solution (e.g., a well-designed cooler with multiple fans or liquid cooling) can help the GPU maintain higher clock speeds for longer periods.
-
Power Delivery: The GPU requires sufficient power to operate at its maximum potential. If the power supply unit (PSU) is insufficient or if the power delivery circuitry on the graphics card is inadequate, the GPU may not be able to reach its maximum boost clock.
-
Workload: The type of workload being executed will also affect the boost clock. Some applications and games are more demanding than others, and they may push the GPU to its thermal and power limits more quickly.
-
Ambient Temperature: The ambient temperature of the room can also indirectly affect the GPU’s temperature and, consequently, its boost clock. A cooler environment will generally result in lower GPU temperatures and higher boost clock speeds.
Variations Among Different RTX 2080 Super Models
While NVIDIA sets the reference specifications for the RTX 2080 Super, different manufacturers (e.g., ASUS, MSI, Gigabyte) produce their own custom versions of the card. These custom models often feature higher factory overclocked speeds, improved cooling solutions, and enhanced power delivery systems.
Therefore, the actual clock speeds of an RTX 2080 Super card can vary depending on the specific model. Some manufacturers may offer cards with a boost clock significantly higher than the reference 1815 MHz. These overclocked models generally provide better performance out of the box, but they may also come with a higher price tag.
To determine the exact clock speeds of a specific RTX 2080 Super model, you should consult the manufacturer’s website or product specifications. These specifications will typically list the base clock and boost clock speeds, as well as any other relevant information about the card’s performance.
Examples Of Custom RTX 2080 Super Models And Their Clock Speeds
To illustrate the variations in clock speeds among different RTX 2080 Super models, here are a few examples:
-
ASUS ROG Strix RTX 2080 Super: These cards often feature a higher boost clock than the reference model, potentially exceeding 1860 MHz or even higher depending on the specific variant (e.g., OC edition).
-
MSI Gaming X Trio RTX 2080 Super: Similar to ASUS, MSI’s Gaming X Trio cards typically offer factory overclocked speeds, with boost clocks reaching around 1845 MHz or more.
-
Gigabyte Aorus RTX 2080 Super: Gigabyte’s Aorus models are also known for their high clock speeds and advanced cooling solutions. Their boost clocks can range from 1860 MHz to over 1900 MHz depending on the specific card.
These are just a few examples, and the actual clock speeds may vary depending on the specific model and revision of the card. Always refer to the manufacturer’s specifications for accurate information.
Overclocking The RTX 2080 Super
Even if you have a non-overclocked RTX 2080 Super, you can potentially increase its clock speeds and improve its performance through overclocking. Overclocking involves manually adjusting the GPU’s clock speeds and voltage settings to push it beyond its factory specifications.
However, overclocking comes with risks. If done improperly, it can lead to instability, crashes, or even permanent damage to the GPU. It’s crucial to proceed with caution and to monitor the GPU’s temperature closely during overclocking.
Tools And Techniques For Overclocking
Several software tools can be used to overclock an RTX 2080 Super, including:
-
MSI Afterburner: A popular and widely used overclocking tool that allows you to adjust clock speeds, voltage, and fan speeds.
-
EVGA Precision X1: Another popular overclocking tool, particularly for EVGA graphics cards.
-
NVIDIA Inspector: A more advanced tool that allows for fine-grained control over GPU settings.
The basic process of overclocking involves gradually increasing the GPU’s clock speeds while monitoring its stability and temperature. You should start with small increments and test the card’s stability after each adjustment. If you encounter crashes or artifacts, you should reduce the clock speed or increase the voltage slightly.
It’s also important to monitor the GPU’s temperature during overclocking. If the temperature gets too high (typically above 85°C), you should reduce the clock speed or improve the cooling solution.
The Relationship Between Clock Speed, Performance, And Bottlenecks
While higher clock speeds generally translate to better performance, it’s important to understand that clock speed is not the only factor determining a GPU’s overall performance. Other components in your system, such as the CPU and RAM, can also impact performance.
If your CPU is significantly slower than your GPU, it can create a bottleneck, limiting the GPU’s performance even if it has high clock speeds. In this scenario, upgrading your CPU may result in a more significant performance improvement than overclocking your GPU.
Similarly, insufficient RAM or slow RAM speeds can also bottleneck GPU performance. Ensure that you have enough RAM (at least 16GB for modern games) and that it’s running at a reasonable speed (e.g., 3200 MHz or higher).
Conclusion
The NVIDIA GeForce RTX 2080 Super is a powerful graphics card with a base clock of 1.65 GHz and a boost clock of 1.815 GHz. However, the actual clock speeds of the card can vary depending on the specific model, thermal conditions, power delivery, and workload. Understanding these factors is crucial for maximizing the performance of your RTX 2080 Super and ensuring a smooth and enjoyable gaming experience. While higher clock speeds generally lead to better performance, it’s essential to consider other components in your system and ensure that they are not bottlenecking the GPU. By understanding the interplay of clock speed, thermal management, and system components, you can unlock the full potential of your RTX 2080 Super.
