Best CPU for RTX 4080 Buying Guide
Getting your CPU is a crucial job when you are not aware that your GPU must be compatible with it. Since you already have your eye on RTX 4080, our suggestion is to go with AMD’s Ryzen 9 3900X that has almost everything your gaming needs. So let’s dig more and find out what other features you should be looking at while getting a processor.
This feature is the average speed from minimum to maximum that will determine how fast you can run multiple tasks at the same time. So starting from 3.6 to 4.6 GHz and even more, your CPU should be able to push harder. When things get intense like modern AAA games that need higher graphics and computing power, an unlocked version of the processor is of great help for overclocking purposes.
There are 12 cores and 24 threads in our suggested model but there are even higher numbers than this. These cores are basically the command senders of your system and enable the tasks that your system will be handling at a time. You might not need too much like 16 cores since you are not building a workstation for deep learning. But there should be enough to load the intensive data and multimedia rendering applications.
A cache plays a huge role in the enhancement of your system’s performance, particularly gaming. Up to 70Mb of cache is a great way to start off your journey and quest of beating down enemies. In addition, DDR 3200 support has enough for the memory to cope with other commands as well.
You better not choose a system that is too demanding when it comes to power consumption. The reason is simple as it will increase a great deal from your electricity bill. From 95W to 105W are somehow acceptable though some tech experts still consider the latter as high thermal design power. We suggest you get a lower to mid tier power supply unit to fuel the rest of the system along with your CPU.
No judgments but whatever processor you chose, its socket must support the latest and modern motherboards. Intel offers LGA 1200, 1700 while AMD is a fan of AM4 sockets.
When gaming is the basic purpose of your system or even if it is editing, your system is more likely to get heated during overclocking. So you better be ready for some dollars on a capable cooler. A prism Wraith cooler with LED touch fulfills aesthetic feels and keeps extra heat out as well.
A good CPU for the RTX 4080 would have at least 6 cores and 12 threads, and a clock speed of at least 4.0 GHz. Some good options include the Intel Core i7-13700K, the AMD Ryzen 7 7700X, and the Ryzen 7 7800X3D.
Some CPUs that are likely to bottleneck a RTX 4080 are the Intel Core i5-12400F, the AMD Ryzen 5 5600X, and the Ryzen 7 5800X. These CPUs are all good performers, but they may not be powerful enough to keep up with the RTX 4080 in demanding games.
The Intel Core i7-12700K is a powerful CPU that should be able to handle the RTX 4080 in most games. However, it may bottleneck the graphics card in some demanding titles. If you are planning on playing at 4K or high refresh rates, it is best to go with a more powerful CPU like the i7-13700K.
It depends on the specific i7 CPU and the games you are playing. Some i7 CPUs, such as the i7-12700K, are powerful enough to handle the RTX 4080 in most games. However, other i7 CPUs, such as the i7-11700K, may bottleneck the graphics card in some demanding titles.
