Buying Guide CPUs for the NVIDIA GeForce RTX 4080

Selecting the correct CPU for the high-function GPU and the whole system might feel intimidating. You need to find the perfect balance between pricing and usability. The choice should be based on the number of threads and cores which enhance the gaming performance. The chipsets with better cores will also facilitate making designs, video rendering or editing, and streaming. In the following section, we have discussed all factors you need to consider in detail.

1. CPU

One of the biggest choices you need to make while looking for the CPU is to finalise between Team Blue, Intel or Team Red, AMD. Both these brands have been in a constant battle for the past several years to be crowned as the best in the business, and there is no one else near them. Let us go through these options individually to make the best choice.

  • Intel: For several years, Intel has been the go-to solution for all gamers for their core performance. With a superior clock speed, it also offers an excellent all-around performance. Therefore, Intel has always been superior to AMD.
  • AMD: AMD has an impressive lineup but lags behind at the time. AMD has few improvements in the architecture and overall build but it is highly expensive when compared to Intel which does not make it an intelligent choice.

2. Cores and Threads

CPU cores and threads are probably the most important assets you must look for when finalising a powerful CPU. There are several other factors too, like clock speed, IPC, generation, and more, but these are the primary ones.


One should always go for the CPU with more cores and threads as they will better handle more things simultaneously or multitask. They are the best pick for content creators or streamers. So, the rule is simple: more cores and threads mean better CPU functionality.

3. CPU Speed

The speed at which the CPU can complete instruction is known as the core speed or CPU speed. The process consists of three parts: fetch, decode and execute. This cycle is required to complete one instruction, and the CPU needs to execute several thousand instructions regularly.

The unit to measure the core speed is GHz. So if the CPU speed of the system is 5, then the CPU is capable of running 5,000,000,000 instructions in one cycle. The faster CPU is indicated by faster CPU speed. This feature is particularly important for gamers.

4. CPU Socket

The CPU socket is the connection between the motherboard and the CPU. Therefore, it is important to choose a CPU socket that can accommodate a large variety of the latest and modern motherboards. Intel offers the LGA 1700 sockets while AMD offers AM5 sockets.

5. Cache

This is another very important factor when booking for a CPU to improve the performance of the system, especially for gaming purposes. It is the memory that allows running games successfully and dealing with other tasks. A great way to start is to look for CPUs with 70 Mb of cache to achieve your quest and beat down the enemies.

6. Warranty

As the CPU is an important and expensive purchase, one should keep the longevity and durability factors in mind. You would not like the CPU to stop working in the middle of some important activities. So, warranty helps to understand the durability factor as more years of warranty is a testament that the product will last longer.
