What to Look for in a CPU in 2023
The first thing you should focus on is the number of CPU cores. While some say that more cores is always better, that’s not always true. Remember, the power of the individual core is also important. If it weren’t, ten-year-old 12-core Intel Xeon CPUs would still be better than modern six-core processors.
If you’re a gamer, you can freely ignore the efficiency cores —also known as E cores— found in 12th and 13th gen Intel processors; E cores are not made for gaming and are only worth it in productivity workloads.
Instead, when looking for a gaming CPU, our best budget Intel CPU pick is fast enough for an entry-level gaming rig unless you like to multitask when gaming. A modern six-core CPU is an optimal choice for mid-range builds, while high-end gaming rigs should feature CPUs with eight or more cores.
Also, you don’t usually need flagship CPUs—you’ll pay a ton of cash but won’t get a noticeable performance bump. Most games don’t scale well beyond eight cores and prefer strong single-core performance over exemplary multithreaded prowess. In other words, a modern six or eight-core CPU is enough for most gamers.
Another thing gamers should be aware of is avoiding creating a CPU or GPU bottleneck. While you can have a CPU that surpasses your GPU in gaming performance, pairing a graphics card with a processor incapable of following it will lead to drops in frames per second (FPS), and sometimes even stuttering.
If you’re looking for a CPU for productivity tasks such as video editing, the more you pay, the better performance you can expect. Many productivity apps can use extra cores and hyperthreading, and they scale quite nicely even when we enter the flagship territory. With that said, some workloads, such as audio mixing, prefer single-thread performance.
To summarize, don’t chase flagship CPUs if you’re a gamer. Regarding productivity, most workloads scale pretty well up to sixteen or more cores. There are scenarios, however, where you’d rather have a fast single-thread CPU, such as audio mixing, and where a powerful GPU is more important than a high-end CPU, such as rendering or AI-related workloads.
Don’t forget about motherboard compatibility. If you’re upgrading, your future processor has to be compatible with your motherboard. You should also get a quality CPU cooling solution to allow the new processor to fully spread its wings. An inadequate CPU cooler can lead to thermal throttling, where the processor gets too hot to work at its maximum performance, dropping frequency to cool down itself.

The Intel Core i3-12100F is the best CPU you can get for $100 or less, period. This Intel CPU is a four-core processor, but its four cores are fast and are enough to run even the most demanding AAA games at 60fps.
Multiplayer games will work at triple-digit frame rates without issues—provided your GPU can handle it. This CPU is also very power efficient, and the included box cooler is enough to cool it down, meaning extra savings since you won’t have to get an aftermarket CPU cooler.
Regarding cons, the Core i3-12100F isn’t the most future-proof choice. Its four-core/eight-thread design can run current AAA titles at 60fps, but future AAA games might struggle to run at or above 60 frames per second. Also, if you have a multi-monitor setup and like having YouTube or Twitch running in the background while gaming, the four cores inside the 12100F won’t be enough to provide a stutter-free gaming experience in some CPU-heavy titles.
If you can’t spend more than $100 on the CPU, get the Core i3-12100F—the F label on Intel CPUs means lack of an integrated graphics card (iGPU) solution, which is fine for gamers since they’ll get a dedicated GPU anyway. If you don’t need a dedicated GPU and are fine with an iGPU, you can get the Core i3-12100.
Gamers who multitask and those with a higher budget looking for something more powerful should check the six-core Intel Core i5-12400F or its 12400 variant with an iGPU. The Core i5-12400F is a great gaming CPU with enough performance for years to come. It offers a considerable performance bump over the 12100F, costing only about $150.

The secret sauce inside this eight-core CPU is 96MB of L3 cache, placed on top of the chiplet containing the eight CPU cores thanks to AMD’s 3D V-cache technology—3D V-cache is a tech that allows AMD to place extra cache above the CPU die. Games love when a CPU has loads of cache memory, and the 7800X3D packs tons of it.
The CPU is also extremely power efficient and much easier to cool down than the flagship beasts from Intel and AMD, allowing you to save extra on the since a quality mid-range CPU cooler will do the job.
The 7800X3D isn’t the only Ryzen CPU with AMD’s 3D V-cache solution. You also have the Ryzen 9 7950X3D and the Ryzen 9 7900X3D. Those two, however, cost much more than the 7800X3D while being slightly slower in games, which is why we don’t recommend them over the 7800X3D.
If you’re looking for the best gaming performance in an Intel CPU, the Core i9-13900KS, a version of the 13900K with higher boost clocks and a higher price, is technically the fastest gaming CPU Intel offers.

Frequently Asked Questions
CPU stands for Central Processing Unit.
No, you cannot. The motherboard in question has to be equipped with a CPU socket compatible with the CPU you plan on getting, and it also has to feature a chipset compatible with the said CPU.
There are a ton of ways to check your CPU temperature. One way is entering your system BIOS. Usually, your CPU temperature will be listed on the BIOS home page. To enter BIOS, press the Del or the F2 key repeatedly just after your PC restarts. The downside of this method is that you cannot monitor CPU thermals while under load.
Another way to check your CPU thermals is by installing a third-party monitoring tool. We recommend Core Temp if you only want to monitor your CPU temperature. If you want to monitor the thermals of your entire system, we recommend using HWiNFO. For more options, check our guides on monitoring your PC’s CPU temperature and on checking your CPU temperature in Windows 11.
Nowadays, a CPU core is a part of the “brain” of the CPU. CPU cores do the heavy lifting during CPU-related tasks, and modern consumer-grade CPUs feature anywhere from 2 to 24 CPU cores. Back in the day, most CPUs featured just one core. Back then, a CPU core was the whole CPU “brain,” not just a part of it.
Cleaning the thermal paste off your CPU is a straightforward procedure. After you take off the cooler heatsink or the cold plate, in case you’re using an AIO cooler, use a cotton pad or a paper towel to clean off the paste. If the paste has hardened, use a cotton swab or a pad with a bit of isopropyl alcohol applied to it to soften and scrape off the paste.
