Overclocking:

This is probably the most basic thing you should know about your new CPU. No matter what kind of program or game you’re running, overclocking can almost always provide better speeds in comparison to normal settings which can be not only beneficial when playing games but also in demanding programs that require your computer to stay active for long periods of time.

That being said, if you’re not an enthusiast, then it’s best not to overclock at all since additional stress on your CPU might cause some serious damage.

Compatibility with RTX 3090:

Since RTX 3090 are mainly designed for graphic systems, they are incompatible with CPUs that do not have integrated graphic units built in. If you want to make sure your CPU will work with RTX 3090, then you should make sure your CPU supports either integrated graphic units or else it won’t work at all!

Price:

Since this lineup mainly focuses on budget CPUs that can be affordable for almost anyone, the prices of these CPUs vary a lot. You shouldn’t focus too much on this factor and simply choose the best product for your needs and budget since everything will depend on how much money you’re willing to spend.

Even if i9 is one of the most expensive processors in this lineup, catching up with i7-9700K doesn’t take too long either so don’t worry about that too much!

Purpose:

We tried to include CPUs for almost any type of program or game in this lineup so that you can get the best out of your RTX 3090. If you’re planning on doing some rendering work as well, then you should definitely get i7-9700K since it’s compatible with dual graphic units and will therefore provide more FPS while playing games.

However, if the only thing you need is good compatibility with RTX 3090, low price and high speeds when running demanding programs like Adobe Photoshop or some other similar program, i5-10600K is probably what you need!

TDP:

All CPUs in this lineup feature low TDP which makes them highly energy efficient and also compatible with cooling systems like fans or water cooling. Since your CPU’s speed depends on how much energy is consumed, having a lower TDP is always beneficial for everyone unless you plan on overclocking your CPU to the maximum possible frequency. Even if you don’t overclock, having a low TDP provides better speeds since less energy will be used by your computer!

Brand:

When making this lineup we tried to make it as universal as possible and include CPUs from most popular brands like Intel and AMD. Both companies have very good products that can satisfy any type of user, so they are definitely worth consideration when building your computer!
