Different Bottleneck Issues On Your Computer Or Laptop

A bottleneck happens when one part of your computer or laptop slows down the rest of the system. This creates a “lag” that affects overall performance. The reason it happens can vary as it could be due to outdated hardware, not enough memory, or mismatched parts. Don’t get it? Take an example of your CPU being “weak” o “outdated” as compared to your GPU. It could restrict the GPU’s ability to perform at its peak, creating a “bottleneck.” This can happen due to different parts. Have a look at the most common types of bottlenecks and why they happen:

CPU Bottlenecks

A CPU bottleneck happens when the processor can’t keep up with other parts of the system. This often causes:

  • Low frame rates in games.
  • Stuttering during gameplay or tasks.
  • High CPU usage, often at 100%.
  • Slow apps or long loading times.

CPU bottlenecks usually occur because the processor is outdated, has too few cores, or runs at a low speed. A lack of RAM or slow storage can make it worse. To fix this, you need to upgrade to a faster or more powerful processor.

GPU Bottlenecks

GPU bottleneck means that the graphics card can’t handle the system’s demands. This often shows up as:

  • Frame drops in games.
  • Low GPU usage, below 95%.
  • Graphics issues like blurry textures or lag.
  • Overheating, which can slow the GPU.

GPU bottlenecks are caused by old or weak graphics cards, not enough VRAM, or high settings that the GPU can’t manage. So, to fix this, you just have to buy a better graphics card with more memory. Make sure that your PC or laptop has updated GPU drivers. You can also improve the cooling setup to prevent overheating. 

RAM Bottlenecks

RAM or memory bottleneck means the same thing. It happens when your computer doesn’t have enough memory to run everything smoothly. This can cause:

  • Slow performance or delays.
  • Long loading times for programs.
  • Crashes when memory runs out.

This happens if you don’t have enough RAM, the RAM is mismatched, or apps use too much memory. To fix RAM bottlenecks, you need to add more RAM to your system. We also recommend using matching RAM modules for better performance.

What is a Bottleneck Calculator?


PC builders and gamers probably have encountered the word "bottleneck calculator." It is a tool that determines if your system's components (like the CPU, GPU, and RAM) work well together. You get a percentage to see if one part is limiting overall performance. A computer bottleneck tester analyzes your system's parts to check for imbalances. You can use this to optimize PC and laptops for tasks like gaming, video editing, or streaming. Our calculator focuses on the following components of laptops and PCs.

Processor (CPU)

The CPU is like your computer's brain. This CPU bottleneck calculator finds out if you have a slow CPU and helps you see if it is holding back the performance of your other components.

Graphics Card (GPU)

The GPU handles graphics and visuals. A GPU bottleneck calculator is a GPU that can't process data as quickly as the CPU sends it, which may lead to wasted GPU potential and poor performance.

Screen Resolution

Higher screen resolutions require more power from both the CPU and GPU. A RAM bottleneck calculator checks if your current hardware setup can handle the chosen resolution and whether the game's high screen resolutions are sacrificing the performance of the CPU and GPU.

Using this tool helps you spot areas where your system might not perform at its best and gives you the insight needed to improve. See how to use it! 

How To Use a Bottleneck PC Calculator

Using a bottleneck checker is simple. Just follow these steps to use a bottleneck PC calculator on a PC or laptop: 

i. Start by entering your key components. 
ii. Enter the type of processor (CPU) your setup has. A list of all common processors is available. 
iii. Then, select your GPU's model name. We have compiled a list of all the latest and earliest models. 
iv. Next, choose the task type for which you'll use your PC or laptop. Select the "graphics card intense task" option if you're building a gaming PC. 
v. Pick the resolution you plan to use for your tasks (1080p, 1440p, or 4K). This choice is crucial because it affects how the calculator measures your system’s ability to handle different levels of graphics. 
vi. After you’ve entered all the necessary information, click “Calculate.” The calculator will generate results showing how well your system is balanced. You will get the result for a bottleneck in percentage. 

Understanding The Results

After using the bottleneck calculator, many people get stuck interpreting the results. Here’s how to make sense of the percentage numbers:

0% Bottleneck

0% means your CPU and GPU are perfectly matched for your chosen task and resolution. Your system is well-balanced, and there are no noticeable performance issues.
In this case, you don’t need to make any changes unless future software or games demand more power. Your system should run smoothly for most tasks. If it still lags after getting a 0% bottleneck, get it checked.

5% to 10% Bottleneck

A bottleneck in this range suggests minor compatibility issues. The imbalance is slight and might not be noticeable during everyday use.
Consider doing more research, like checking benchmarks on YouTube for your specific CPU and GPU combination. You might not need to upgrade any parts, but adjusting settings in games or software can help improve performance.

Over 10% Bottleneck

A bottleneck over 10% indicates a more serious performance issue. It often results in noticeable slowdowns during demanding tasks like gaming or video editing.

Identifying which component, the CPU or GPU, is the limiting factor is a good idea. Then, based on benchmarks and real-world performance tests, consider upgrading the weaker part. Upgrading could lead to a significant performance boost.

Note! Take these results as “estimated” points of bottlenecks. They are not 100% accurate. Several factors, like software updates, driver improvements, and specific application requirements, can affect performance. So, while calculators give valuable insights, further research and testing are necessary.

How Does A Bottleneck Calculator Work?

A bottleneck calculator works by analyzing PC components and how they work together. It checks whether your system's CPU, GPU, or other parts are holding back overall performance. Here’s how it works:

Input Your System’s Specs

As you enter key details like your CPU, GPU, and screen resolution, the calculator starts analyzing them. These components directly affect how well your system performs under different tasks. The more accurate the specs you enter, the more reliable the results.

Analyzing Task Performance

The tool then evaluates your system’s performance based on your selected task. It uses data from benchmarks, like frames per second (FPS) for gaming or CPU/GPU usage for other tasks. For example, when running a game, it measures how smooth the FPS is. It’s like a fps and bottleneck calculator that gives results indicating which part is slowing things down.

Identifying the Bottleneck

Once the calculator examines your system’s performance, it identifies which component (CPU or GPU) is the limiting factor. It compares the workload between the two and figures out which is causing the game or task to run slower than it could.

Estimating Performance Impact

After detecting the bottleneck, the fps bottleneck calculator estimates how much performance could improve if you upgraded the problematic component. It assumes that fixing the bottleneck will boost overall system performance. Remember that real-world results can differ.

Considering Other Factors

The calculator also considers other important elements, like RAM speed, screen resolution, and even game settings. Higher resolutions, for example, demand more from your GPU. Similarly, intensive settings like ray tracing require powerful graphics cards to perform well.

Database of Benchmark Results

The calculator compares your system to a database of popular CPU and GPU combinations to make its predictions. These combinations help it predict how likely a bottleneck is and how much improvement could come from an upgrade.

Common Bottleneck Scenarios

Here are some common bottleneck problems and easy ways to fix them.

CPU Bottleneck

As mentioned above, CPU bottleneck occurs when CPU usage hits 100%, but GPUs aren’t used enough (less than 40%). It causes slow gaming performance, lower frame rates, and lag.

Solution: If the bottleneck is due to the CPU, upgrading it can make a significant difference. Alternatively, higher screen resolution can take some pressure off the CPU. To fix a CPU bottleneck, here’s what you need to do:

  • Upgrade to a more powerful processor. A mid-range CPU like the Intel i5 or AMD Ryzen 5 can often handle the load for gaming.
  • Lower game settings and resolution to reduce the strain on the CPU. 
  • Only a hardware upgrade is the best solution for more demanding games.

RAM and Storage Bottleneck

Slow loading times, stuttering, and lag are signs of a RAM bottleneck or slow storage. If your PC has too little RAM or uses an old HDD, it can struggle to keep up with games and apps. Use the RAM Bottleneck Calculator to see if your PC has it.

Solution:  Here’s what you need to do to maximize your storage full performance:

  • Add more RAM to your system (16GB or more is ideal). Make sure the RAM is compatible with your motherboard.
  • If you're still using an HDD, switch to an SSD. It will speed up your PC and reduce loading times.  
  • An HDD could still be a secondary option if you need more storage space.

GPU Bottleneck

A GPU bottleneck occurs when the CPU is too strong for the GPU. In this scenario, the CPU works fine, but the GPU isn’t used enough, resulting in low frame rates and poor gaming performance.

Solution: If your GPU is the weak link, reducing the graphics quality or lowering the resolution can help. If you have a GPU bottleneck, try these:

  • Increase the game’s resolution or settings to push the GPU harder. 
  • If that doesn’t help, upgrading to a more powerful GPU will balance things. 

Use tools like the PC Builds Bottleneck Calculator to find out where your PC may be struggling and make smart upgrades for better performance.

Reduce Bottlenecks By Optimization

You already know that for your PC to perform at its best, all parts must work together. When one part is too slow, it holds the whole system back. Here’s how you can balance your PC for better performance in 3 steps:

1. Choose the Right Parts

  • CPU and GPU: Pick a CPU and GPU that match the power. If one is stronger than the other, it can cause a bottleneck. A good balance helps both parts perform well together.
  • RAM: Start with 8GB of RAM for basic tasks. If you have a fast CPU and GPU, 16GB or more is better. It keeps your system running smoothly.
  • Storage: Use an SSD for your operating system and games. SSDs are much faster than HDDs and help your PC run quicker.
  • Display: Make sure your monitor’s refresh rate matches what your GPU can handle. If your monitor is too advanced for your GPU, it could cause issues.

2. Optimize Your System

  • Update Drivers and OS: Constantly update your drivers and operating system. It keeps your PC running at its best.
  • Power Settings: When gaming or performing heavy tasks, set your power plan to "Ultimate Performance." It will increase your CPU speed.
