If you’re planning to build a new PC or upgrade your existing one with the NVIDIA RTX 4070, choosing the right CPU is crucial. The performance of your graphics card can be significantly impacted by the processor you pair it with. Using a subpar CPU may create a bottleneck, limiting the performance of your GPU and preventing you from enjoying the full potential of your build.
In this guide, we’ll explore what makes a CPU a good match for the RTX 4070, how to identify potential bottlenecks using a bottleneck calculator, and provide a list of the best CPUs to pair with the RTX 4070 in 2024. This article is structured to help you make an informed decision and avoid common pitfalls when configuring your system.
Understanding Bottlenecks and How to Avoid Them
A bottleneck occurs when one component in your PC is significantly less powerful than the other, preventing the more powerful component from operating at its full potential. When it comes to CPUs and GPUs, bottlenecks often happen when the CPU can’t keep up with the GPU’s processing power. This is commonly referred to as a CPU bottleneck.
Using a CPU bottleneck calculator or a PC bottleneck calculator can help you identify potential mismatches between your CPU and GPU. These tools analyze your system’s configuration and provide a percentage indicating the extent to which your CPU or GPU is holding back overall performance. A bottleneck percentage under 10% is generally considered optimal, while anything above that may result in decreased frame rates, stuttering, or system instability.
Factors to Consider When Choosing a CPU for the RTX 4070
Before diving into the best CPUs to pair with the RTX 4070, it’s important to understand the factors that influence the compatibility between a CPU and a GPU:
- Core Count and Threads: The number of cores and threads plays a crucial role in handling multi-threaded applications and games. For gaming and general productivity, a CPU with at least 6-8 cores and 12-16 threads is recommended.
- Clock Speed: Higher clock speeds allow the CPU to perform tasks faster, which is particularly beneficial for gaming. Aim for a CPU with a base clock of 3.5 GHz or higher.
- Cache Size: Larger cache sizes help the CPU access frequently used data more quickly, which can lead to improved performance in complex applications and games.
- Architecture: Modern architectures, like Intel’s 13th generation or AMD’s Ryzen 7000 series, offer better power efficiency and performance than older models.
- Bottleneck Percentage: As mentioned, use a bottleneck calculator to ensure the CPU and GPU work harmoniously. The calculator will estimate the performance loss based on the selected CPU and GPU.

Using a Bottleneck Calculator to Finalize Your Choice
After shortlisting potential CPUs, it’s crucial to verify your choice using a bottleneck calculator. Here’s how:
- Input Your CPU and GPU: Choose your desired CPU and the NVIDIA RTX 4070 in the bottleneck calculator. Some tools may also ask for additional inputs like RAM size and speed.
- Analyze the Results: Check the bottleneck percentage. If it’s under 10%, the CPU and GPU are well-balanced. A result above 15% indicates a noticeable performance gap, suggesting that the CPU may need an upgrade.
- Adjust Your Options: Based on the results, you can switch to a more powerful CPU or opt for a different GPU if necessary.
Conclusion
Pairing the NVIDIA RTX 4070 with the right CPU is key to unlocking its full potential.
