Estimate your CPU + GPU fit for Cities: Skylines II

CPU and GPU game workload balance diagram for Cities: Skylines II
Use the workload profile as a directional guide for Cities: Skylines II. Resolution and visual settings usually move load toward the GPU; very high refresh targets and complex simulation can move the limit toward the CPU.

Is Cities: Skylines II CPU or GPU intensive?

This is a CPU-bound simulation where complex background logic stresses the processor on a few main threads. Prioritise single-thread performance and large cache (X3D) plus fast, low-latency RAM. Late-game cities overwhelm the processor with simulation logic; prioritise a high-end CPU with strong single-thread performance. You can sanity-check any CPU/GPU pairing for this kind of workload with the Bottleneck Estimator — set the game type to simulation to see how the balance shifts.

How to read this estimate

The checker weighs both CPU and GPU against this game’s workload profile. It is a directional fit guide, not a measured FPS promise. Game patches, map complexity, ray tracing, upscaling and target refresh rate can change the result.
