Does Undervolting GPU Decrease Performance? ANSWERED

Decreasing the voltage available to your GPU is known as undervolting. This should preserve performance close to stock levels while boosting efficiency. The main areas for improvement with undervolting are power demand and heat.

Why, if GPUs can potentially run better at a lower voltage, don’t they arrive this way from the factory? Simple: Like with CPUs, each GPU’s silicon can vary. As a result, some GPUs will be able to cope with higher voltages and faster speeds than others. The standard parameters are aligned with the average tolerance.

Does Undervolting GPU Decrease Performance?

No, not even during high-intensity activities like gaming. Undervolting your GPU has no significant effect on performance. The only way your GPU performance can decrease is if you start to notice instability. If that is the case, revert back to normal factory settings, and then everything will turn out to be okay.

Because lower voltage values emit less heat, undervolting does not degrade performance but extends the graphics card’s life. On the other hand, lowering the voltage may cause the card to become unstable, leading to artifacts, BSOD, and other problems. To compensate for this, underclocking the graphics card is commonly utilized.

When processors leave the factory, they normally have a preset clock and voltage. The manufacturer does not need to test and tune them extensively to ensure stability because the voltage is frequently much higher than required. As a result, most processors’ voltages may be reduced by the user, allowing them to run cooler and, as a result, increase/save battery life.

Does Undervolting Lower FPS?

No, your FPS will just be more stable and will also be resistant to fluctuations. Undervolting will not have an enormous impact on your gaming experience. Moreover, you can expect to enjoy your games as you normally would. In fact, the lower energy usage might just make the gaming experience much more stable.

It is worth mentioning that undervolting your GPU can boost the performance of your games when your setup suffers from high temperatures and throttling issues. This is because undervolting reduces the thermal dissipation of the processor. Therefore it is much less likely to overheat.

Does Undervolting Reduce Heat?

Yes, undervolting directs less energy to your processor resulting in less heat. Undervolting is the process of finding a stable clock speed at lower voltages. This can vary from processor to processor, depending on the silicon used. However, undervolting guarantees heat reduction as less energy is used overall.

Heat reduction is the main reason many people opt for undervolting their processors in the first place. Overheating is a big issue for many processors and can gradually reduce their performance. This ultimately shortens the lifespan of the processor.

Undervolting and therefore reducing heat can increase the lifespan of your processor. This is because using less energy will not wear out your processor nearly as fast as if you were using high amounts of energy. This means that your processor health will be better off after undervolting it.

Does Undervolting GPU Affect Mining Performance?

No, the hash rate is not affected significantly. Of course, the hash rate is unlikely to increase as a direct consequence of undervolting as well. Less power is used, and your GPU is cooler and can perform better. A cooler GPU can result in a higher hash rate, so undervolting will not harm your mining prowess.

There is a possibility of undervolting too much. If that is done, then your GPU performance will drop. This drop in performance can harm your mining performance. This is why it is important to undervolt in a stable manner that is most suitable for your setup.

The only drawback is that you’d have stability problems if you undervolt too much. The lower your undervolt, the less overclocking you’ll be able to do. Because manufacturers want to be safe, they maintain the stock voltage somewhat high while allowing consumers to overclock. Both of these restrictions are lowered by undervolting.

Does Undervolting Reduce Electricity Usage?

Yes, a small amount of electricity is saved per undervolted computer due to lower power consumption. This may not be incredibly convincing since the electricity saved is not too significant per computer. However, most houses use more than one computer, which can greatly reduce your electricity usage over time.

However, libraries and workspaces can benefit significantly from undervolting their computers’ GPUs. Since there are many GPUs, the amount of electricity saved will be significant. Furthermore, the reduced heat will also help with the temperature of the rooms and have a positive impact on the employees and students.

In the case of cryptocurrency mining farms, this can also be very significant. Undervolting can significantly reduce your electricity and cooling costs. This makes your mining more efficient and increases the lifespan of your mining components. Cooler GPUs, as discussed, can also perform better and have a higher hash rate.

Pros Of Undervolting GPU:

  • Less Heat
    Less heat equals less energy use. You’ll save money on your electricity bill. Lower heat equals better thermal performance for your system’s other components, such as the CPU. As contemporary GPUs carry more and more power, this might be crucial in decreasing the impact on your PC ecosystem. Furthermore, your power supply will be less stressed.
  • Relatively Secure
    It’s easy to do with standard software like MSI Afterburner, and it’s also relatively secure. It’s also likely that it’ll help you extend the life of your GPU by reducing the amount of heat stress it’s subjected to overtime. 
  • Improved Heat Dissipation 
    Do you require a powerful GPU to fit into a small form factor enclosure? The good news is that undervolting will improve the experience significantly. Because heat dissipation in small enclosures is often limited, you’ll receive better thermals while preserving performance in these tight spaces.

Cons Of Undervolting GPU:

  • Incorrect Settings May Lead To Poor Performance
    While your GPU may be technically sound, incorrect settings may poor performance. If the GPU’s voltage is too low and not applied correctly, it might cause instability and lower frame rates. After making voltage changes, it’s vital to double-check and test your GPU’s performance to guarantee it’s improving.
  • Needs Expertise
    You’ll need to be comfortable fiddling with your expensive GPU settings. While undervolting is often safer than overclocking, it does require some knowledge and trial and error.
  • Requires Constant Tinkering
    It may not be as straightforward as setting it up and leaving it alone. Due to new driver updates or even changing ambient temperatures, you may need to go in and modify your settings for maximum performance from time to time. 

Is Undervolting CPU Better Than GPU?

No, undervolting the CPU is not as popular as undervolting the GPU. It is most likely because most consumers desire to overclock their CPU rather than risk slowing it down. Undervolting a desktop CPU also necessitates tinkering with BIOS settings, which is significantly more difficult than undervolting a GPU. 

Furthermore, Intel CPUs can no longer be undervolted due to an exploit known as Plundevolt. Perhaps this is one of the reasons why people normally prefer undervolting their GPUs instead and why this is far more popular than undervolting your CPU.

Undervolting didn’t function properly with Ryzen CPUs until the Ryzen 5000-series CPUs arrived. Previously, undervolting Ryzen CPUs meant decreased performance unless you were willing to go through a time-consuming and complicated method that restricted speeds to specific voltages, limiting your CPU’s boost clocks.

Is Undervolting GPU Safe?

Yes, there are various safety safeguards in place to really protect you from bricking your GPU, CPU while using MSI Afterburner to undervolt GPUs and PBO2 to undervolt Ryzen 5000 CPUs. Therefore, even if you go too high or too low, the safety features will kick in long before you harm a component permanently.

So when you’re tinkering with your GPU while undervolting, you do not need to worry too much. This is not the same case for CPUs. Undervolting is inherently risky with CPUs because there’s always the possibility of something going wrong. For example, if Intel didn’t disable CPU undervolting, you might have gotten a no-boot situation. The same safety mechanisms don’t always exist for CPUs as for GPUs.


We can thus see that there are many reasons why you would want to benefit from undervolting your GPU. Undervolting your GPU reduces the power it uses while maintaining the same level of performance. Of course, you need to tinker around with your settings just a little until you find the sweet spot.

Once you’re done tweaking the settings for optimal undervolted GPU performance, you’re all set to enjoy less heat and noise from your system. In addition, with built-in safety features for undervolting, you are unlikely to ruin your GPU – so don’t worry.
