How Much Gpu Use Is Each Colab Compute Unit – A Completea Guide!
Google Colab offers shared Tesla K80/T4 GPUs on the Free plan, while Pro and Pro+ plans provide priority access to faster GPUs like P100, V100, and A100.
In this article, we will break down the GPU usage for each Colab compute unit in simple terms, helping you understand how to make the best use of your allocated resources.
What is Google Colab?
Google Colab (short for Colaboratory) is a free cloud service offered by Google, allowing users to write and execute Python code in a browser-based environment. It’s similar to Jupyter Notebooks but with added benefits like free access to powerful hardware resources.
Colab provides two types of compute units:
- CPU (Central Processing Unit): The regular processing unit that handles most basic tasks.
- GPU (Graphics Processing Unit): Specialized hardware designed to handle complex calculations, especially in tasks like machine learning, image processing, and data analysis.
For users looking to accelerate their machine learning models, GPUs are extremely helpful, as they perform many calculations in parallel, reducing training time.
How much is 100 colab compute units?
Google Colab doesn’t directly price “compute units” in a specific, quantifiable manner. However, in the context of Colab Pro and Colab Pro+, the costs are tied to monthly subscriptions, rather than compute units:
- Colab Pro costs $9.99/month and provides access to better GPUs (like Tesla P100) and more resources.
- Colab Pro+ costs $49.99/month and offers priority access to even more powerful GPUs (like Tesla V100 or A100).
The concept of compute units might be referring to available GPU hours or resource allocation, which varies based on your subscription tier, with Colab Pro and Pro+ offering more consistent and higher-performance access.
Understanding Colab’s Compute Units:
When you use Google Colab, you’re given access to different compute resources based on the plan you choose. The two main plans are:
Free Plan:
- You get free access to basic computer units.
- Limited access to GPUs and TPUs.
- Usage is subject to limits (e.g., session duration and GPU availability).

Colab Pro and Pro+ Plans:
- Colab Pro gives you priority access to GPUs.
- Colab Pro+ provides even more dedicated resources, including faster GPUs and longer session times.
- These plans also give more storage and fewer interruptions compared to the free plan.
Let’s dive deeper into how much GPU usage each Colab compute unit has, especially in the context of the free plan and Pro plans.
How Much GPU Use is Available in Each Colab Compute Unit?
In Google Colab, the GPU availability varies by the type of compute unit:
- Free Tier: Offers access to Tesla K80 or T4 GPUs with up to 12GB VRAM. Usage is shared, and availability depends on demand, so access may be limited or intermittent.
- Colab Pro: Provides access to Tesla P100 or T4 GPUs with up to 16GB VRAM. You get more stable access and priority over free-tier users, offering better performance and fewer interruptions.
- Colab Pro+: Offers access to powerful Tesla V100 or A100 GPUs with up to 40GB VRAM. This tier ensures priority access, extended usage, and the highest performance available.
How many compute units are in the GPU?
In the context of GPUs, compute units usually refer to the processing elements responsible for parallel computations. For example, the Tesla K80 has 2496 CUDA cores, the T4 has 2560 CUDA cores, the P100 has 3584 CUDA cores, the V100 has 5120 CUDA cores, and the A100 has 6912 CUDA cores. Google Colab doesn’t directly track compute units, but resources are allocated based on GPU cores and overall usage, measured in GPU time and memory.
How to Monitor and Manage GPU Usage in Colab:
Check GPU Availability:
To check GPU availability, run a command to display important details about the GPU you’re using, such as the model (e.g., Tesla K80, T4, P100), memory usage, and CUDA version. This helps you track GPU health and resource consumption, ensuring efficient resource use. Monitoring GPU usage ensures you’re aware of any limitations, especially on the free plan, where resources are shared and can be restricted based on demand.
Monitor GPU Utilization:
For deeper insights into GPU usage, use specific Python libraries to monitor GPU availability and resource utilization. This confirms if a GPU is actively being used or if any issues are occurring. Monitoring GPU utilization helps you gauge how much load your GPU is under, and ensures that you’re not exceeding limits that might cause slowdowns or session disconnects, leading to an optimized workflow without resource bottlenecks.
Limit Idle Time:
To prevent session disconnections, avoid long idle periods when using the GPU. Google Colab may terminate sessions after periods of inactivity to conserve resources. You can keep your session alive by running simple background tasks, such as print statements or small processes, to keep the GPU engaged. This ensures that your session stays active and uninterrupted, preventing automatic disconnects, especially when working on long-running tasks or large-scale machine learning projects.

Avoid Overloading GPU Resources:
While it’s tempting to maximize GPU performance, overloading the GPU with too many processes can result in slower performance, errors, or session disconnections. To avoid this, use GPU resources efficiently by breaking down tasks into smaller batches or optimizing your code. Keep an eye on memory usage to prevent bottlenecks and resource exhaustion, ensuring that the GPU can handle your workload without encountering performance degradation or errors from excessive load.
How to Maximize GPU Use in Google Colab:
Optimize Your Code:
Optimizing your code is crucial for maximizing GPU use in Colab. Implement efficient algorithms and use techniques like batch processing to reduce the load on the GPU. Well-optimized code ensures that tasks are processed more efficiently, reducing memory consumption and speeding up execution. By minimizing unnecessary GPU usage, you free up resources for other tasks and prevent bottlenecks, ensuring that your computations are performed at their optimal speed with minimal resource waste.
Use Colab Pro or Pro+:
Upgrading to Colab Pro or Pro+ provides priority access to GPUs, which means faster and more consistent performance. Colab Pro offers access to better GPUs like Tesla P100, while Colab Pro+ provides access to even more powerful options, like Tesla V100 or A100. These plans help reduce the likelihood of session interruptions or limited access, especially during periods of high demand, ensuring that you can run intensive tasks with minimal delay or resource constraints.
Clear GPU Memory:
To prevent GPU memory congestion, clear the memory between tasks, especially if previous jobs used significant resources. If memory is not freed up, new tasks may fail to run or experience performance issues. You can manually release memory using commands to ensure the GPU can handle new jobs efficiently. This ensures that your GPU remains available for processing tasks without running into memory-related errors or slowdowns, helping to maintain smooth operations throughout your session.
Use Google Drive for Storage:
Storing datasets on Google Drive instead of uploading and downloading files repeatedly helps save time and improve efficiency. Drive provides persistent cloud storage, allowing you to access your data across different sessions without the need to re-upload it. This also ensures that large datasets are always available, making it easier to work on long-term projects without worrying about storage limits or session disruptions, thus enhancing your workflow on Google Colab.
