When building a gaming PC, the most expensive part is the graphics card, and you want it to make the most of its money. Then the question arises: which processor should be chosen for this video card so that it does not limit it in games? Our specially prepared material will help you in this dilemma.
So it turns out that the main thing in the computer is the processor and it commands everything else. It is he who gives orders to your video card to draw certain objects, and also calculates the physics of objects (even with PhysX, the processor counts some operations). If the video card does not work at full capacity, and the processor can no longer faster, then there is a bottleneck effect, when system performance is limited by its weakest component.
In reality, there are always operations when the video card does not strain at all, and the percent plows to full, but we are talking about games here, so we will reason in this paradigm.
How is the load distributed between the processors and the video card?
It should be noted that changing the settings in the game changes the ratio of the processor and video card load.
As you increase the resolution and graphics settings, the load on the video card increases faster than on the processor. This means that if at lower resolutions the processor is not a bottleneck, then at higher resolutions it will not.
With a decrease in the resolution and graphics settings, the opposite is true: the load on the processor when calculating one frame almost does not change, and the video card becomes much lighter. In such a situation, the processor is more likely to become a bottleneck.
What are the signs of a bottleneck?
The test requires MSI Afterburner. You need to look at the graph “Loading GP.
You also need to know the load on the processor. This can be done in the system monitoring in the task manager, there is a graph of the processor load.
So what are the signs that the processor is not revealing the graphics card?
- GPU load is not close to 100%, and CPU load is all the time around this mark
- GPU load graph jumps a lot (maybe a poorly optimized game)
- When changing graphics settings, FPS does not change
It is by these signs that you can find out if there is a bottleneck in your case?
How to deal with the choice of processor?
To do this, I advise you to watch the processor tests in the game you need. There are sites that specifically deal with this (overclockers.ru, gamegpu.com).
An example of a test in the game Tom Clancy’s The Division:
Typically, when testing processors in different games, graphics settings and resolution are indicated. The conditions are selected so that the processor is the bottleneck. In this case, you can find out how many frames in a given resolution a particular processor is capable of. Thus, you can compare the processors with each other.
Games are different (captain is obvious) and the requirements for the processor may be different. So, in one game everything will be fine and the processor will cope with scenes without any problems, and in another the video card will be cooled down while the processor will have great difficulty performing its tasks.
This is most influenced by:
- the complexity of physics in the game
- complex geometry of space (many large buildings with many details)
- Artificial Intelligence
- When choosing, we advise you to focus on just such tests with the graphics settings you need and the FPS you need (what your card will pull).
- It is advisable to watch the most demanding games if you want to be sure that future new products will work well.
- You can also take a processor with a margin. Now games work well even on chips from 4 years ago (Intel second generation), which means that a good processor will now delight you in games for a very long time.
- If the FPS in the game is normal, and the load on the video card is low, load it. Boost your graphics settings to keep your graphics card running at full capacity.
- When using DirectX 12, the processor load should be slightly reduced, which will reduce the requirements for it.
We hope that our article helped you decide on the choice of processor for your video card. If you have any questions, then write in the comments, you are welcome 🙂 You can also share the model of your processor and video card in the comments.
