Keep These Things in Mind Before Getting CPU for RTX 3080 Card

Look out for these things before making a purchase.

PSU (power Supply Unit)

PSU or also called power supply unite Is responsible of converting AC to DC and then delivering all those current to PC components. It is most crucial component of any PC building step and most users tend to ignore it. PSU comes in different output power. Their power can range between 100 to 2000 wattage.

If you using an underpowered PSU, chances of system crashing will be high under heavy load. If you going to couple RTX 3080 with any of the above-mentioned CPU than it is highly recommended to get at least 750w PSU. RTX 3080 by itself is quite powerful card and can draw up to 350w power. So, getting less than 750w PSU can cause problem to your system.

Overclocking

Both Intel and AMD allow Overclocking to their CPU. Overclocking enables the CPU to be clocked faster than the base frequency so it can process more instructions per second. Many of advance users tend to overclock their CPUs to get maximum possible performance. But overclocking comes with some cons as well such as overheating, system instability etc.

If you building PC for the first time, it is highly recommended you use your system at base frequency and do overclocking after doing proper research. But there is no doubt that overclocking can improve 5-10% performance and can gain 10-15 more FPS. Also, make sure your motherboard allows your CPU to overclock and you have sufficient cooler for your CPU.

Bottlenecking

If I explain it in simple term, bottlenecking happened when you couple high performing hardware with a low performing one. For example, if you got an SSD, RTX 3080, 16GB DDR4 RAM but CPU you got is intel 2nd generation than bottlenecking is going to happen. All the other hardware processing data much faster but CPU delaying that data processing causing bottlenecking hence system will not perform as expected. Your games also going to face low FPS issue. Poor multi-tasking etc. So, replacing that poor performing second gen CPU with let’s say Ryzen 9 will remove bottleneck and your system will run super-fast after that.

Single Core vs Multi Core Performance

In gaming, many of AAA titles utilize single core performance. In the past, most of games were designed to utilize single core only. But this has starting to change. Now many latest AAA games can utilize multi core, multi-threaded cores more efficiently so you can get maximum possible FPS. So, if you planning to purchase and play new titles or going to do video rendering work, it is highly recommended to get a good multi core CPU such as Ryzen 9 5900x.

Intel or AMD

Both are known for making great chips. Intel has been in CPU market for quite a long time. But their new CPUs are not that value to the money if you ask me. For example, if you look at their latest gen CPUs, they offer less threads as compared to its competitor. Also, most of their latest CPUs are based on 14nm architecture. Another thing, Intel changes their socket with each generation which means you have to upgrade motherboard as well if you going to upgrade to latest intel generation.

On the other hand, AMD has improved a lot and providing better performing and less hot CPU at reasonable pricing. Their Ryzen 9 series is quite amazing and offers best value to the buck. Also, Ryzen 9 based on 7nm architecture hence they will generate less heat as compared to intel one. We personally like Ryzen CPUs more than intel one due to their amazing multi-core performance. AMD has AM4 socket and they don’t change their socket with each generation which means you don’t have to upgrade mother board if you going to upgrade CPU. Both intel and AMD offers overclocking though. So, its up to you which you want to go with.



How to Properly Insert CPU in Motherboard

Conclusion

RTX 3080 is quite powerful graphics card. Combining this powerful GPU with a weak CPU can be serious bottlenecking and you might not get the desired results. Above mentioned CPUs works great with latest 3080 gpu. If you going for multi-threaded performance than Ryzen 9 is best CPU for rtx 3080 GPU.

Same, if you looking for single core performance than Intel i7 10th generation will be best CPU for rtx 3080 graphics card. Now it depends on your budget what you exactly want but whichever you choose from the above will going to give you best gaming experience.
