CPU and GPU to avoid bottlenecks
First of all, you should know that the topic of PC bottlenecks is very relative, because it depends above all on the type of use you are going to give it. For example, on a gaming PC there will be a huge bottleneck with an RTX 4090 and an Intel Celeron processor, since the CPU is so underperforming that it will not allow the GPU to perform at its best. However, if we are dealing with a PC designed for databases, it does not matter if you have an NVIDIA GT730 graphics card with a top-of-the-range processor, since in this area the GPU matters very little and what really matters is a processor, a powerful storage and RAM.
That being said, below we are going to recommend some combinations of processor and graphics card that work well together, so that you will avoid bottlenecks in most cases (the performance you are going to have is something else, which we are looking for is a combination that does not have a bottleneck). We seek to have less than a 5% bottleneck to be able to say that the combination is adequate.
To play at 1080p
- AMD Ryzen 5 3600X with a GeForce RTX 2060 SUPER – This combination has a 0.3% bottleneck.
- Intel Core i7-8700K with a GeForce RTX 2060 SUPER: 0% bottleneck, almost perfect match.
- AMD Ryzen 7 5800X with a GeForce RTX 2080: 1.5% bottleneck.
To play at 1440p or 4K
- Intel Core i7-12700K with a GeForce RTX 3070 Ti: 1.5% bottleneck.
- AMD Ryzen 7 5800X3D with a Radeon RX 6800 XT: 0.3% bottleneck.
- AMD Ryzen 9 5950X with a Radeon RX 6950 XT: 2.9% bottleneck.
For general tasks at 4K resolution
- AMD Ryzen 9 5900X with a GeForce RTX 3090 Ti: 0.2% bottleneck.
- Intel Core i5-12600K with a GeForce RTX 3070 Ti: 3.1% bottleneck.
- AMD Ryzen 3 3100 with a Radeon RX 6750 XT: 2.9% bottleneck.
As you can see, there are many combinations, and it depends a lot on the type of use you are going to give the PC, since a computer designed for gaming at Full HD resolution is not the same as one designed for 4K resolution. However, at the end of the article you have a link to a web page where you can try different configurations and you will see the bottleneck you can expect to have, easily and quickly.
