How to pick the best CPU for RX 7900 XT

The RX 7900 XTX is a powerhouse with impressive features and specifications. To ensure all of these features work as best as possible, you need to pair it with a strong CPU, and for that, you need to keep a couple of things in mind so you can make an informed decision. We’ve listed some of these factors below.

Compatibility

The first thing you need to consider is compatibility, specifically whether the CPU you’re leaning towards will work well with the GPU. Since the RX 7900 XTX is the top AMD card, choosing a less powerful CPU will hinder its ability to perform at its best. Another thing to look out for is the express configuration the CPU supports. If it works with 4.0, you can use it on an older build and call a day. However, if it works with the latest 5.0 version, you might have to purchase a new motherboard and RAM as well if you don’t have them already. A workaround for this is to go for the 13th-generation Intel processors, as they’re compatible with PCIe 4.0 and 5.0.

Clock speed and cores

This is another important aspect to keep in mind, as a higher clock speed generally means that the CPU can process instructions faster, which can improve your computer’s overall performance. Additionally, you’ll need to look at the cache and cores. If you’re mainly using the rig for gaming, core count shouldn’t be a priority. On the other hand, if you are using it for productivity, then you want a good number of cores ready to take the workload.

Cache

The cache goes down the same line. This is a small amount of very fast memory that is built into the CPU and is used to store frequently accessed data. A larger cache can improve the performance of the CPU, as it allows it to access data more quickly. This means that you should be able to get better load times, reduced access time, and better in-game performance.

Temperature and cooling solutions

The temperature of the processor can have an impact on its performance. If it gets too hot, it’ll start to thermal throttle, leading to decreased performance. As this is a powerful GPU, you’re most likely looking at a powerful CPU for that. However, the more decked out they are, the more power they consume, which will generate more heat. So, consider your ambient temperature, check out reviews for the CPU, and see whether an air cooler could keep the temperature under control or if you will need an AIO or a custom water loop cooling solution.
