Welcome back to the Channel! In this video, we will be exploring the process of undervolting the 5700 XT GPU and applying power plate tables. Despite facing some challenges with our Recording tools, we'll do our best to demonstrate the performance adjustments and share our findings with you.

Overview of the 5700 XT GPU

To start, let's do a quick overview of the 5700 XT GPU for those who may be unfamiliar with it. The GPU offers impressive performance and has left a positive impression on us as reviewers. However, showcasing its capabilities without reliable recording tools has been a challenge. Despite this, we will provide you with the information you need to understand the undervolting process using WattMan and MSI Afterburner.

Troubles with Tools and Setup

As Mentioned earlier, our recording tools are currently malfunctioning, preventing us from capturing footage for this video. We apologize for the inconvenience and will rely on alternative methods to showcase the process. Moving forward, we will be using WattMan for our tuning activities.

Understanding Performance Metrics

Before diving into the undervolting process, it's essential to understand the performance metrics displayed in the tuning software. At the top of the interface, you can find the metrics section, which provides information about the card. Just below this, you'll see the frequency and voltage curve, where we control voltage and frequency. Other sections include the fan curve, temperature sensors, power limit, current power, and memory speed.

Stock Settings and Performance Analysis

Let's begin by observing the stock settings and performance of the GPU. The stock core frequency of my particular card is 2074 MHz, with a voltage of 1203 millivolts. Interestingly, this voltage seems quite high for the clock speed, and it's unclear if it varies between cards. The base clock is 1605 MHz, and the Game clock is 1755 MHz. It's worth noting that the maximum boost clock is 1905 MHz, which raises questions about the chosen stock value. Despite these uncertainties, we will test the card's performance at stock settings before proceeding with the undervolting process.

Benefits of Undervolting

Undervolting is a technique that allows us to reduce the voltage supplied to the GPU while maintaining stable performance. By achieving the same performance with lower voltage, we can significantly reduce temperature and power consumption. Undervolting also provides the opportunity to fine-tune the GPU's behavior and potentially achieve quieter operation.

Step-by-Step Guide to Undervolting

Now let's dive into the step-by-step process of undervolting the 5700 XT. First, we need to toggle the settings to allow manual adjustments. Then, we'll set a constant fan speed to monitor temperature differences accurately. We recommend running this process for an extended period to observe peak temperature, although we'll only cover the initial results due to the card's current instability.

Monitoring Temperature Differences

With the undervolt applied, it's crucial to monitor temperature differences compared to the stock settings. By reducing the voltage, we should see a significant decrease in temperature. The power consumption will also be noticeably lower. These adjustments allow for quieter operation and better overall efficiency. We'll run the same game and analyze the metrics to evaluate the impact of undervolting.

Effects on Power Consumption

Undervolting not only reduces temperature but also has a direct effect on power consumption. Through our testing, we found that undervolting the card by lowering the voltage from 1.2 volts to 0.966 volts resulted in a reduction of up to 50 watts. This substantial decrease in power consumption allows for a lower fan RPM while providing excellent performance. The benefits of undervolting extend beyond temperature reduction and include energy savings as well.

Testing and Benchmark Results

To thoroughly assess the impact of undervolting, we conducted various tests and benchmarks. Notably, we achieved impressive results during the Fire Strike benchmark, where we managed to reach a graphics score of 28,137. This score surpasses that of my stock Radeon 7, demonstrating the 5700 XT's performance potential. Further testing with different benchmarks revealed differences in clock speeds, prompting further investigation.

Exploring PowerPlay Tables

In our exploration of undervolting, we also delved into the realm of PowerPlay tables. These tables allow for more advanced clock adjustments and can push the GPU even further. However, we do not recommend applying extensive overclocks to blower-style cards due to the potential increase in temperature and the need for aggressive fan speeds to maintain thermal stability. We will continue to monitor the capabilities of PowerPlay tables and provide a more detailed analysis in future videos as drivers mature.

Recommendations for Blower-Style Cards

Blower-style cards, such as the 5700 XT, Present unique challenges when it comes to cooling. While undervolting significantly improves temperature and power consumption, pushing the GPU to higher clocks may require much higher fan speeds to keep the junction temperature within safe limits. We advise exercising caution when utilizing exotic cooling solutions and considering the trade-offs between clock speed, temperature, and noise levels.


In conclusion, the 5700 XT GPU represents a significant step forward for AMD. Despite encountering some challenges with our recording tools and driver stability, we found the card to be efficient and powerful when undervolted. Its performance and value make it an excellent choice for gamers and enthusiasts. We hope this video has provided valuable insights into undervolting and showcased the potential of the 5700 XT.
