I noticed my GPU was running above 90% while my CPU sat at just 10%, and it made me realize how GPU-heavy my game was. It felt like my CPU was just chilling while the GPU was doing all the heavy lifting!
If your GPU is above 90% while the CPU is at 10%, it likely means the task is GPU-intensive, such as gaming or rendering, and your CPU isn’t a bottleneck. This is normal for optimized systems running graphics-heavy applications.
Stay tuned with us as we dive deeper into the topic of “GPU above 90 but CPU at 10.” We’ll explore why this happens, what it means for your system, and tips to ensure optimal performance!
Is It Normal For The Gpu To Work Harder Than The Cpu In Certain Tasks?
Yes, it’s normal in tasks like gaming, video rendering, or 3D modeling, where the GPU does most of the work. These tasks rely on graphics processing, which is the GPU’s job. The CPU handles other functions like managing processes or input/output tasks.
If the CPU usage is low while the GPU is high, it means your system is likely running efficiently. This indicates the CPU is not a bottleneck. However, this balance depends on the type of workload. For general computing tasks, the CPU might take the lead instead.

What Types Of Applications Cause Gpu Usage To Exceed Cpu Usage?
Here are some common types of such applications:
Gaming
Modern games are designed to be GPU-intensive because they involve rendering high-quality graphics, textures, and animations. The GPU handles tasks like rendering 3D environments, processing shadows, lighting, and visual effects, while the CPU mainly manages game logic and background tasks.
Video Editing And Rendering
When editing or exporting videos, the GPU is often used to accelerate tasks like rendering effects, transitions, or exporting in high-resolution formats. Programs like Adobe Premiere Pro and DaVinci Resolve can offload much of the processing to the GPU to speed up the work.
3d Modeling And Animation
Software like Blender, Maya, or Cinema 4D relies heavily on the GPU for rendering 3D models, animations, and complex simulations. The GPU excels at parallel processing, making it ideal for these tasks compared to the CPU.
Machine Learning And Ai Training
Machine learning applications and AI training involve processing large datasets and running numerous calculations. Tools like TensorFlow or PyTorch often use GPUs because they can handle these tasks faster than CPUs by leveraging parallel processing capabilities.
Video Playback In High Resolution
Playing high-resolution videos, especially in 4K or 8K, can utilize the GPU for decoding and rendering video frames. The CPU plays a smaller role, as the GPU takes on the heavy lifting to ensure smooth playback.
Graphic Design And Image Processing
Applications like Photoshop or Illustrator often use GPUs to handle rendering, applying filters, or managing complex layers. This is especially true when dealing with high-resolution images or advanced editing techniques.
Cryptocurrency Mining
Mining cryptocurrencies like Ethereum requires solving complex mathematical problems, which GPUs are well-suited for. This process involves repetitive calculations, which the GPU can perform efficiently due to its parallel processing capabilities.
Virtual Reality (Vr) And Augmented Reality (Ar)
VR and AR applications demand high-quality rendering in real-time to provide immersive experiences. This puts most of the workload on the GPU, as it needs to generate detailed graphics at high frame rates.
Does A Gpu-Heavy Workload Indicate An Optimized System?
A GPU-heavy workload often means your system is focusing resources where needed, which can be a sign of optimization. For example, in games, the GPU should handle most of the graphics processing. If your CPU isn’t overloaded, it ensures smooth performance without unnecessary bottlenecks.
However, this doesn’t guarantee optimal performance if the GPU is overworked or overheating. Proper system balance and monitoring are key. So, while a GPU-heavy workload is usually a good sign, always check your hardware temperatures and usage.

What Causes A Gpu To Run Above 90% While The Cpu Stays At 10%?
Here’s a detailed breakdown of why this happens and the contributing factors:
Gpu-Intensive Workloads
Tasks that rely heavily on the GPU, such as gaming, 3D rendering, video editing, or machine learning, cause the GPU to handle most of the processing. These workloads involve operations like rendering high-quality graphics, running simulations, or applying complex effects, which are better suited for the parallel processing capabilities of the GPU.
Optimized System Balance
In a well-optimized system, the workload is distributed to prevent bottlenecks. The GPU processes graphics-heavy tasks while the CPU manages background operations, input/output, and system-level processes. This balance ensures the CPU doesn’t need to work harder than necessary, keeping its usage low.
Game Or Software Design
Some games and software are specifically designed to offload most of the work to the GPU to maximize performance. For example, modern games use the GPU to render visuals, while the CPU handles game logic, physics, and AI, which are less demanding in comparison.
High Graphics Settings
Running applications at high graphics settings (e.g., 4K resolution, ray tracing, ultra texture quality) increases the GPU’s workload. Meanwhile, the CPU’s workload doesn’t scale as much because it is not directly responsible for rendering.
Low Cpu Dependency In Task
Certain tasks naturally require less CPU power. For example, when watching high-resolution videos or performing basic system tasks, the GPU might handle decoding or rendering while the CPU stays idle.
Hardware Capability Mismatch
If your GPU is much more powerful than your CPU, the GPU can handle a larger workload without being constrained by the CPU. This disparity can make the CPU appear underutilized during GPU-heavy tasks.
Background Applications And Processes
If your system is optimized and not running many background processes, the CPU has less to manage, resulting in lower usage. The GPU continues to handle the main workload, especially in tasks that demand high graphical power.
Thermal And Power Management
Modern GPUs and CPUs have efficient power and thermal management systems. If the CPU is not needed as much for a particular task, it may reduce its clock speed to save power, further lowering its usage while the GPU operates at full capacity.
Bottleneck-Free Environment
High GPU usage and low CPU usage often indicate that the CPU is not a bottleneck, which is good for overall system performance. This means the GPU is free to operate at its maximum potential without being limited by the CPU.
How Can I Monitor Gpu And Cpu Usage Effectively?
You can monitor GPU and CPU usage using free tools like Task Manager in Windows. Under the “Performance” tab, it shows real-time GPU and CPU stats. Tools like MSI Afterburner or HWMonitor give more detailed insights, including temperatures and clock speeds.
For gaming or rendering, in-game overlays often display usage stats too. Keeping an eye on usage helps identify bottlenecks or overheating issues. Regular monitoring ensures your system runs smoothly. It’s a good habit to check before and after demanding tasks.

Should I Be Concerned If My Gpu Usage Is Consistently High But Cpu Usage Is Low?
High GPU usage with low CPU usage is often normal for GPU-intensive tasks like gaming or rendering. However, if the GPU is at 100% constantly, it could indicate a system strain or poorly optimized software. Overheating or performance drops could follow if the GPU is overworked.
Check temperatures and ensure proper cooling to avoid long-term damage. If you’re not running heavy tasks and the GPU is still maxed out, it could be a software issue or malware. Investigate and address any abnormal behavior.
