Intel CPU efficiency and gaming power consumption tested

Intel CPU efficiency and gaming power consumption tested

When it comes to choosing a new processor, many of us weigh the options between Intel and AMD, two powerhouses in the industry. It’s tempting to focus solely on the speed of these CPUs, but it’s equally important to consider how efficient they are and how much power they consume. This article delves into the performance of Intel and AMD processors, specifically the Intel 14700K and AMD 7800X, and how they manage power efficiency across different types of workloads, from gaming to production tasks.

The concept of CPU efficiency is simple: it’s the measure of how much work a processor can do for each watt of power it uses. This is becoming a critical consideration, not just for the sake of your electricity bill, but also for the broader goal of reducing environmental impact. For gamers, efficiency might be looked at in terms of frames per second per watt, while those using their computers for production tasks might consider metrics like hours per render in Blender or millions of instructions per second per watt.

Intel CPU gaming power consumption tested

If you are wondering just how much power and Intel CPU uses when gaming you’ll be pleased to know that the amazing team over at Gamers Nexus  have carried out in-depth gaming power consumption test on Intel CPUs. Enabling you to make the best decision when parting with your hard own cash.

Here are some other articles you may find of interest on the subject of Intel :

To get a clear picture of CPU efficiency, Gamers Nexus put these processors through a series of tests. Looking at how they performed under various conditions, including their default settings, when power limits were imposed, and when frame rates were capped. Our gaming tests examined power consumption in both constrained and unconstrained scenarios, and also monitored the power spikes that occur when games are loading or when assets are being rendered, to simulate real-life usage.

For the most accurate power consumption measurements, they used a PMD interposer. This tool ensured that their data reflected the true power usage of the CPUs across different tasks. What they found was quite interesting. AMD generally had the upper hand in power efficiency during gaming. But when they applied power constraints, Intel showed a marked improvement in efficiency, especially with Blender rendering tasks. These findings are significant because they can lead to cost savings and have environmental benefits. The efficiency of a CPU can have a considerable impact on long-term expenses and, on a larger scale, the health of our planet.

These insights highlight why it’s important to factor in power efficiency when reviewing CPUs. A review that includes these metrics provides a more complete understanding of a CPU’s overall performance and its implications for both the user and the environment. Choosing your next CPU should involve a careful consideration of efficiency. It’s not just about your wallet or the environment; it also speaks to the technological prowess of your processor. Stay engaged and contribute to the conversation about CPU efficiency and power consumption.

How to reduce your Raspberry Pi 5 power consumption by 140x

How to reduce your Raspberry Pi 5 power consumption

The Raspberry Pi 5, a mini PC that is now available for purchase, has been praised for its enhanced capabilities and increased power when compared to the previous Raspberry Pi 4. However this increased processing power also draws high power consumption, especially in Power Off mode. This high power consumption is not a feature unique to the Raspberry Pi 5, but is also a characteristic of its predecessor, the Raspberry Pi 4. Both these models, by default, leave the System on a Chip (SoC) powered up in a shutdown state, leading to power consumption of 1.2-1.6W, even when no other peripherals are plugged in other than the power source.

The default setting of the Raspberry Pi 5 is a significant contributor to its high power consumption. This is due to the fact that some Hardware Attached on Top (HATs) experience issues if the 3v3 power rail is off, but the 5v is still active. As such, the Raspberry Pi 5 ships with the setting POWER_OFF_ON_HALT=0, causing it to continuously consume power.

Reduce Raspberry Pi 5 power consumption

Fortunately, a solution has been developed to mitigate this issue. Jeff Geerling, a well-known figure in the Raspberry Pi community, has developed a method to reduce the Raspberry Pi’s power consumption by up to 140 times while in Power Off mode. This solution involves editing the Electrically Erasable Programmable Read-Only Memory (EEPROM) configuration and adjusting the following settings: BOOT_UART=1, WAKE_ON_GPIO=0, POWER_OFF_ON_HALT=1.

The process of editing the EEPROM configuration is straightforward. After saving the configuration and rebooting, the power consumption should significantly decrease from 1-2W to 0.01W or less when shut down. This is a remarkable reduction, making the Raspberry Pi 5 much more energy-efficient in Power Off mode.

Importantly, the functionality of the Raspberry Pi 5 is not compromised by implementing this solution. The Raspberry Pi 5 can still boot with the POWER_OFF_ON_HALT setting, the power button still operates as expected, and the red LED remains illuminated when the device is shut down. Moreover, the Real-Time Clock (RTC) continues to keep time, indicating that watchdog-related functions should also continue to operate normally.

While the Raspberry Pi 5 does have a high power consumption in its default Power Off mode, this issue can be effectively addressed. By editing the EEPROM configuration, users can significantly reduce the device’s power consumption without compromising its functionalities. This solution represents a significant stride towards making the Raspberry Pi 5 more energy-efficient and environmentally friendly.
