  • Intel's hybrid-core CPUs offer impressive performance and energy efficiency in most use cases.
  • Intel has introduced a new feature called APO to address the power consumption issue.
  • Intel continues to innovate and refine its CPU architecture to prioritize power efficiency.


Intel’s Game-Changing Hybrid CPUs Boost Efficiency, Yet Draw Excessive Power by 230W

Intel has long been known for its powerful CPUs that deliver high performance and energy efficiency. However, a recent investigation by GamersNexus has uncovered an irregularity in Intel’s hybrid-core CPUs that raises concerns about power consumption.

Power efficiency has always been a key focus for Intel, which is why they introduced a heterogeneous core architecture consisting of P and E-Cores. The idea behind this architecture is to offload lightly threaded workloads to the “Efficiency” cores, thereby reducing power consumption. Unfortunately, it seems that these efficiency cores don’t always work as intended.

The investigation focused on testing the Core i9-14900k in Metro Exodus, a popular game among PC gamers. Surprisingly, when running the game at the “Low” graphics preset, a strange discrepancy was observed. Enabling the Application Optimizer (APO) feature reduced the maximum single-threaded usage of the E-cores, resulting in improved performance and reduced power consumption. On the surface, this may seem like a positive outcome. However, it actually has a negative impact on the majority of gamers using Intel’s hybrid-core CPUs.

The anomaly discovered in Metro Exodus revealed that the efficiency cores were being assigned threads that were better suited for the performance cores. This led to a decrease in performance and an increase in power draw. However, with APO enabled, the Windows scheduler corrects this behavior, resulting in a significant reduction in power consumption of up to 230W. This is quite surprising considering that the E-cores were initially designed to reduce power draw, not increase it.

Fortunately, this issue seems to be limited to specific scenarios, with the “Low” graphics setting in Metro Exodus being one of them. Intel has introduced a new feature called APO to address this problem. However, it is important to note that APO is only supported on two of Intel’s fastest 14th Gen chips. This limitation poses a challenge for gamers who are using the 13th Gen counterparts, as they do not support APO.

While this discovery may raise concerns among Intel users, it is important to remember that the issue is not widespread and only affects specific scenarios. Intel’s hybrid-core CPUs still offer impressive performance and energy efficiency in most use cases. However, it is crucial for Intel to address this anomaly and provide support for APO on a wider range of CPUs to ensure a seamless gaming experience for all users.

In conclusion, Intel’s hybrid-core CPUs have undoubtedly brought about significant improvements in power efficiency. However, the recent investigation has shed light on an irregularity that affects their performance in certain scenarios. With the introduction of APO, Intel aims to rectify this issue, although its limited support on specific chips poses a challenge for some users. As Intel continues to innovate and refine its CPU architecture, it is crucial for them to prioritize power efficiency without compromising performance, ensuring a seamless gaming experience for all PC gamers.

Technology Explained


CPU: The Central Processing Unit (CPU) is the brain of a computer, responsible for executing instructions and performing calculations. It is the most important component of a computer system, as it is responsible for controlling all other components. CPUs are used in a wide range of applications, from desktop computers to mobile devices, gaming consoles, and even supercomputers. CPUs are used to process data, execute instructions, and control the flow of information within a computer system. They are also used to control the input and output of data, as well as to store and retrieve data from memory. CPUs are essential for the functioning of any computer system, and their applications in the computer industry are vast.


E-Cores: E-Cores (Efficiency Cores) are a type of technology used in the computer industry to provide a more efficient and reliable way of powering and cooling computer components. They are made up of a combination of copper and aluminum, and are designed to be more efficient than traditional copper cores. E-Cores are used in a variety of applications, such as in CPUs, GPUs, and other computer components. They are also used in servers, laptops, and other electronic devices. The technology is designed to reduce heat and power consumption, while also providing a more reliable and efficient way of powering and cooling computer components.
