Is Cities Skylines CPU Or Gpu Intensive (2024)

When it comes to the popular city-building game Cities: Skylines, one question that often arises is whether it is more CPU or GPU intensive. Well, the answer may surprise you. While the game does utilize both the CPU and GPU, it leans more towards being CPU intensive.

This is because the game involves simulating complex city dynamics, managing traffic, and rendering a large number of objects on the screen simultaneously. These tasks heavily rely on the processing power of the CPU to handle the calculations and AI algorithms involved. Therefore, having a robust and capable CPU is crucial for experiencing smooth gameplay and maximizing performance in Cities: Skylines.


In the case of Cities Skylines, the game is primarily CPU intensive rather than GPU intensive. This means that having a powerful processor is more important for smooth gameplay and city simulation. However, having a decent GPU can enhance the visual quality and performance as well. So, to get the best experience in Cities Skylines, it is recommended to have a good balance of CPU and GPU power.

Understanding the Intensity of Cities Skylines on CPU and GPU

When it comes to playing the popular city-building game Cities Skylines, many players wonder whether it is more CPU-intensive or GPU-intensive. To truly understand the performance requirements of this game, it's essential to delve into the intricacies of how it utilizes the central processing unit (CPU) and graphics processing unit (GPU) of your computer.

CPU Intensity of Cities Skylines

The CPU plays a crucial role in running Cities Skylines as it handles various processes, including simulation, artificial intelligence, and calculations. The game's complex mechanics, which involve simulating the lives and interactions of thousands of individual citizens, placing and managing buildings, handling traffic, and more, heavily rely on the CPU's processing power. As a result, the game can be quite CPU-intensive, especially in larger cities or when using mods.

One of the primary reasons why Cities Skylines is CPU-intensive is the game's realistic approach to simulating urban life. The CPU needs to calculate the behavior and interactions of each individual citizen, including factors like employment, education, healthcare, transportation, and more. These calculations require significant computing power, and as the city grows in size, the CPU has to handle an increasing number of calculations simultaneously.

Besides simulating the lives of citizens, the CPU also handles other crucial aspects of Cities Skylines, such as traffic management, power distribution, water supply, and industrial production. These components involve complex algorithms that rely heavily on the CPU's ability to process information quickly and efficiently. Additionally, when using mods or custom assets that add extra features and complexity to the game, the CPU workload increases even further.

Overall, Cities Skylines heavily relies on the CPU for its simulation and calculation processes. Therefore, having a powerful CPU with multiple cores and high clock speeds can significantly improve the game's performance, especially in larger cities or when using mods that increase the complexity of gameplay.

Recommended CPU Specs for Cities Skylines

While the specific CPU requirements for Cities Skylines may vary depending on individual preferences and gameplay scenarios, here are some recommended CPU specifications that can ensure a smooth gaming experience:

  • Quad-core CPU with high clock speeds (e.g., Intel Core i5 or AMD Ryzen 5)
  • 6 or more CPU cores for larger cities and complex gameplay (e.g., Intel Core i7 or AMD Ryzen 7)
  • 12 or more CPU cores for extensive mod usage and highly detailed cities (e.g., Intel Core i9 or AMD Ryzen Threadripper)

It's important to note that while a powerful CPU is crucial for optimal performance, other factors such as RAM, GPU, and storage also play a role in the overall gaming experience. Therefore, it's recommended to have a balanced system with sufficient resources to support Cities Skylines.

GPU Intensity of Cities Skylines

While the CPU primarily handles the simulation and calculations in Cities Skylines, the graphics processing unit (GPU) also has an impact on the game's performance, particularly in rendering the graphics and visuals of the city. The GPU is responsible for rendering the 3D models, textures, lighting, shadows, and other visual elements, creating the immersive city-building experience that the game is known for.

However, compared to the CPU, Cities Skylines is considered to be less GPU-intensive. The game's graphics requirements are not as demanding as some other modern, graphically intensive games. This is primarily because the focus of Cities Skylines is on simulating and managing the city and its citizens, rather than pushing the boundaries of graphical fidelity.

While a capable GPU is important for smooth gameplay, especially at higher resolutions or when using mods that add visual enhancements, a mid-range or even entry-level dedicated graphics card is typically sufficient to run Cities Skylines at acceptable frame rates. This makes the game more accessible to a wider range of players who may not have high-end gaming rigs.

However, it's worth noting that integrating mods or custom assets that introduce high-resolution textures, detailed models, or visual effects can increase the GPU workload. In such cases, having a more powerful GPU can help maintain a stable frame rate and improve the overall visual quality of the game.

Recommended GPU Specs for Cities Skylines

To enjoy Cities Skylines with decent graphical settings and smooth frame rates, the following are some recommended GPU specifications:

  • Mid-range dedicated GPU (e.g., NVIDIA GeForce GTX 1660 or AMD Radeon RX 5600 XT)
  • High-end dedicated GPU for higher resolutions and visual enhancements (e.g., NVIDIA GeForce RTX 3070 or AMD Radeon RX 6700 XT)

It's important to consider that these recommendations may vary depending on individual preferences, desired graphical settings, and use of mods or custom assets that affect visuals.

Balancing CPU and GPU for Optimal Cities Skylines Performance

Now that we have explored the CPU and GPU intensity of Cities Skylines, it is crucial to strike a balance between these two components for optimal performance. While having a powerful CPU can handle the game's simulation and calculations efficiently, it's equally essential to pair it with a capable GPU to ensure smooth graphics rendering.

Having a well-matched CPU-GPU combination allows for a seamless gaming experience, especially in larger cities or when using mods that increase gameplay complexity and visual enhancements. It's recommended to choose a CPU and GPU that offer a balance in terms of processing power, clock speeds, and VRAM capacity, ensuring that neither component becomes a bottleneck for performance.

Additionally, maintaining a well-ventilated system and ensuring proper cooling for both the CPU and GPU can contribute to maximizing their performance and longevity. Overheating components can lead to thermal throttling, causing noticeable drops in frame rates and gameplay stuttering.

In conclusion, Cities Skylines relies heavily on the CPU for its simulation and calculations, making it CPU-intensive, especially in larger cities and with the use of mods. While the GPU plays a lesser role in overall performance, a capable graphics card is still essential for smooth rendering of the game's visuals. By finding the right balance between CPU and GPU, players can enjoy an optimal gaming experience in Cities Skylines.
