Can we stop the CPU from becoming a limiting factor even when aiming for very high frame rates?
Can we stop the CPU from becoming a limiting factor even when aiming for very high frame rates?
Current setup: Ryzen 3600, Rx 5700xt, 16gb DDR4 3200mhz Cl16
My friends often say I don’t need a 2080ti for 144hz games like Modern Warfare, but I think my 5700xt already meets that requirement even if it’s not the highest. As the title suggests, is it feasible to avoid CPU bottlenecks even when they seem possible? I’m confused why top-end CPUs haven’t kept up with lower-end GPUs in terms of instruction handling. From what I know, a CPU bottleneck happens when the GPU sends too many instructions for the CPU to process. So why hasn’t there been a solution to this?
Bottlenecks appear in EVERY system, and their position changes depending on your activity, being entirely tied to the application you're using.
You're correct about the example, but at its core, a bottleneck is just the weakest point in your chain.
In simple terms, if your GPU can do more than your CPU, the CPU will slow down; similarly, if your CPU outperforms your GPU, then the GPU will be the bottleneck.
When your CPU becomes the bottleneck, it means it's operating at maximum capacity and can't handle more tasks, while the GPU isn't reaching its full potential.
This situation is entirely influenced by the application and how you're using the system.

You're correct about the example; in its simplest version, a bottleneck is just the weakest part of your chain. In short, if your GPU can do more than your CPU, the CPU will slow down, and vice versa. When your CPU becomes the limiting factor, it's because it's operating at maximum capacity while the GPU isn't performing well enough. Therefore, bottlenecks are a natural part of any system and every one has its own. They strongly depend on the application and your usage style, so keep an eye on refresh rate and resolution as much as possible. The only real solution is to restrict how much you use each component, effectively preventing the system from reaching its full potential. To maintain high frame rates, it's best to let your parts operate within their designed limits. If visual problems arise, you can try measures like FPS caps, FreeSync or G-Sync, or using a monitor that matches your CPU and GPU specs.
