Guide To Pick The Best CPU for RTX 3070
Following is the list of features that make the CPU ideal for RTX 3070. Keep in mind the list to make sure you are getting the one that is compatible with your needs and that can tackle your gaming.

Functioning Compatibility And Versatility
The first important thing that you have to pay attention to is the compatibility and versatility of the CPU processor you’re purchasing. You have to make sure that the one you are purchasing is compatible with the components you have such as the motherboard, GPU, and other related hardware.
You have to make sure that the CPU is able to perform functions and actions that you actually need in your gaming. Keep in mind this and check the functionality of the CPU before finalizing it as it is an expensive purchase so of course, you are not going to change it every day.
No Of Cores And Threads
Then comes the number of cores and threads. Look for the CPU that has more cores and threads integrated into it. Cores are the mini processor inside the big processor so more cores are always better to get a more enhanced and more professional experience of using a computer.
And if you are a pro gamer you always have to make sure that the CPU you are considering does not have a low count of cores in it. It will not work better in case the CPU has less than 4 cores nor will it be adequate for RTX 3070. Make sure to focus on the number of cores and threads in order to get the best adequate CPU for the best possible gaming.
Cache Memory
Cache memory is a temporary memory that resembles short-term memory somehow. It is the memory that is useful for gamers as they don’t have to reach the main memory every time they play the games. The higher the cache memory, the better the CPU functionality is. With higher cache memory, the CPU will be fast, smooth, and quicker than the one that has a low value of cache memory.
You have to be aware of the value of cache memory before finalizing the CPU. Always make sure to purchase the CPU that comes with adequate cache memory, according to your gaming level and gameplay. Heavier games demand more cache memory as compared to the new and light games.
It basically is of 3 types L1, L2, and L3. All 3 of these are different and you have to be aware of the value of all three before finding the CPU for RTX 3070. I will recommend you go with the one that comes with a higher value of L3, instead of L2 and L1 because L2 and L1 have low space as compared to L3 which is very roomy and spacious.
Cooling System
Checking out the cooling system and inbuilt thermal setup is of utmost importance before finalizing the CPU. To maintain the proper thermal temperature and make sure there are no complications of high temperature, you have to be aware of the cooling setup that is available in the CPU. It should be able to tackle heavy temperatures and should be able to maintain the desired temperature range.
The cooling system should have proper fans and thermal dissipation, so there are no complications of high temperature or other damages that otherwise can damage not only the components, and hardware but also the functioning and performance of the hardware too.
So make sure to focus on the cooling system that is offered by the CPU you are willing to purchase, in order to make it ideal for gaming of all skill levels.
