How to Calculate Bottleneck CPU GPU?

A new game can stress your PC to the maximum and it can happen that your machine is not functioning how you would like it to. In some cases it is simply because either the CPU or the GPU is not working properly. But how do you know which one is malfunctioning? You can check it by using the Bottleneck Calculator for CPU and GPU.

Let’s learn how to calculate Bottleneck CPU GPU and how to fix these Bottleneck. 

What is a CPU Bottleneck?

When your graphics card (GPU) processes data faster than your processor (CPU) can, you have a CPU bottleneck. Your GPU is ready to render the next frame, but your CPU has not prepared the data for the GPU. In this case, you may see that your usage of the GPU doesn’t reach 100%, which means the GPU is not fully utilized.

What Are The Signs of a CPU Bottleneck?

• Low GPU utilization (far less than 95%) while in-game.
• High CPU usage (often 90% or greater).
• Frame rates do not go up comfortably even when lower graphics settings.
• Performance dips in CPU heavy titles or areas (e.g., large crowds or open world).

What is a GPU Bottleneck?

A GPU bottleneck is just the opposite of a CPU bottleneck. In this case, your processor is pushing data to the graphics card faster than the GPU can render it. It means that while the CPU may be underutilized, the GPU is running at full throttle, meaning 100% utilization.

This type of bottleneck usually occurs in graphically intensive games where the GPU is doing the majority of the work, like first-person shooters or action games with high-resolution textures and a lot of visual effects. When your system has a GPU bottleneck, usually the only good option for improving performance is to upgrade the graphics card.

What Are The Signs of a GPU Bottleneck?

• GPU usage is high (generally, around 100%) during gameplay. 
• CPU usage is low (generally, below 50%). 
• Frame rates increase noticeably when lowering graphics setting.
• Performance decreases in graphically intensive games or areas (for example, ultra textures, ray tracing).

How to Identify Bottlenecks?

You can identify bottlenecks by running a bottleneck test with the given tools. 

• Utilizing software such as MSI Afterburner, HWMonitor, or Task Manager to display live stats on CPU and GPU utilization, frame times, CPU usage, and GPU usage during gameplay.
• Lowering the graphical settings and resolution to see if frame rates significantly increase or lower. If you notice a drastic increase in frame rates then a bottleneck is likely your GPU. If the performance remains the same or marginally improves, your CPU can further limit performance.
• Testing CPU-heavy games e.g., Civilization VI or Total War, and GPU-intensive games like Cyberpunk 2077 and Red Dead Redemption 2. You can see how each affects performance.

How to Calculate Bottleneck CPU GPU?

A CPU and GPU bottleneck calculator can assist you in measuring your performance limitations. The entire process is easy and quick; you will only need some basic information about the computer hardware. We have put together a guide to help you get started:

Step 1: Before you begin, you must know the following details:

Step 2: Choose “Bottleneck Calculator” or “PC Builds”, are known for their accuracy and ease of use.

Step 3:  Now, locate the input field for CPU information. You can select your CPU model from a drop-down list or manually type in the exact model

Step 4: Next, provide details about your graphics card and RAM capacity. These components significantly impact system performance, and accurate data ensures precise results.

Step 5: Click the “Calculate” button (or similar option) to analyze your system’s performance. The tool will process the data and present insights into potential bottlenecks.

By utilizing a CPU bottleneck calculator, you can make informed decisions about hardware upgrades and ensure your PC operates at peak efficiency.

Mobile vs. Desktop Bottlenecks

When considering bottlenecks, mobile gaming devices behave vastly differently from desktop PCS because of a limited form factor, thermal constraints, and power efficiency.

1. Thermal Throttling is More Prevalent in Mobile Devices

1. Mobile CPUs or GPUs often throttle their performance under load to prevent overheating.
2. For example, the Intel i7-12700h in a laptop can throttle down from 4.7GHz to 2.5GHz after an extended gameplay session due to the high internal temperatures in the laptop.
3. Desktop CPUs like the i7-12700K can maintain higher sustained performance due to better airflow and larger heat sinks.

2. Power Limits can Determine Performance

1. Laptop GPUs (NVIDIA RTX 4070 Laptop GPU as an example) have a Total Graphics Power (TGP) of around 115W.
2. Desktop GPUs (like the RTX 4070) can go as high as 200-220W that equals at least 30-40% better performance in AAA titles.
3. This power gap creates a more frequent opportunity for a GPU bottleneck in a mobile device, given the movement to a graphics-intensive session.

3. Benchmark Comparison: Desktop vs. Laptop

Laptops are anywhere from 20-40% slower than desktops with generally similar specs in sustained gaming due to thermal throttling and reduced power constraints.

4. Mobile Devices Have Limited Upgrade Options

1. With a desktop PC, you will likely have the option to upgrade the CPU or GPU to alleviate a bottleneck in your setup.
2. Most gaming laptops will not allow you to upgrade the GPU and the CPU is typically soldered to the motherboard.
3. You are generally left with RAM or storage upgrades and you will not fix any CPU and GPU bottlenecks.

5. Mobile Bottleneck Solutions

1. Use a cooling pad to manage thermal throttling.
2. Undervolt your CPU and GPU.
3. Reduce in-game performance.

Optimize Your System Based on Calculator Results

After identifying CPU bottlenecks through the calculator, it’s time to upgrade your system. Here’s how to make the most of the recommendations:
:

1. Upgrade Your CPU

When a calculator indicates your CPU is the primary bottleneck, the only change to make is an upgrade. Look for processors with labels promoting higher clock speeds, more cores and newer architectures. Upgrading to a faster CPU improves overall performance, helps multitask easier and advance your gaming and productivity experience.

2. Upgrade Your Graphics Card

If you know you’re okay with your CPU but your graphics card is weak, your focus will be on a GPU upgrade. A better graphics card can take on demanding graphics tasks that slow down your system, and allow for better, more seamless movement in gameplay or rendering and do a better job at it! This is important if you rely on graphics-intensive applications or modern games.

3. Fine-Tune Software Settings

Not all optimizations are going to require hardware changes. There are software optimizations you could do as well, and they will do a lot for you:

1. Lowering in game graphics to lessen CPU utilization.
2. Updating drivers will ensure that the hardware is performing optimally.
3. Enabling technology like DLSS or FSR can provide AI powered upscaling.
4. Optimize your system by closing background services can free CPU and GPU.

Approach these strategies together to minimize CPU and GPU bottleneck.

Common CPU Bottleneck Calculator Mistakes To Avoid

1. It’s important to input the right CPU, GPU, and RAM specs so that you don’t get invalid results.
2. Treat the results from calculators as estimates and not facts. The actual results may vary.
3. Plan for component upgrades; calculators usually take a snapshot of the current components only.
4. Drivers and software not currently being up-to-date can throw off performance and are often confused with bottlenecks.
5. If you have an overheat, it can take off some bottleneck indicators; be sure to check your system temp regularly.
