New & used CPU processors | Best processors for PC

Also known as the Central Processing Unit, the CPU is essentially the heart of any device – without it, machines just simply wouldn’t function. While this PC component is relatively small in size, this chip is responsible for all the main processes and task executions, which are done by performing logical and decision-making operations that include math. It’s no surprise that, depending on how advanced your computer processor is, the more tasks your gaming PC can handle. It is also the biggest factor in ensuring the smoothest gameplay possible, so if you’re looking to upgrade your gaming PC, don’t forget to invest in a proper CPU for gaming. Here in Eneba, we offer a variety of new and used gaming PC processor listings by other gamers like you, from budget gaming CPUs to the best models out there!

What does a CPU do?

As mentioned beforehand, this component processes and executes tasks. The number of concurrent tasks your computer can handle depends on the number of cores the CPU has. The typical core processor available on the market includes from 2 to 8 cores – the bigger the number, the more your system can do. There are six types of CPUs:

• Single-core – this is the oldest type of CPU that can only execute one command at a time, not efficient for multitasking;
• Dual-core – this type of CPU has two cores inside the chip and can execute multiple tasks at faster speeds than the single-core one;
• Quad-core – this type of CPU divides all workload into four cores, ensuring even smoother multitasking, and is generally preferred by people who edit videos, games, create designs and more;
• Hexa-core – the next step in the evolution of CPUs, this one includes 6 cores and is usually found in personal computers as it ensures faster working speed, clock speed, and performance;
• Octa-core – this CPU consists of 8 cores, most of the time the chip has a dual set of quad-core processors and it is more suited for really demanding tasks;
• Deca-core – this CPU consists of 10 and is the most advanced computer processor to date.

Another important aspect of these cores are the threads, and every core has two of them. They are small sequences of programmed instructions that execute processes – the more there are of them, the more tasks your system can do. Keep in mind that CPUs also differ depending on the generation, meaning the latest generation CPUs can support more features than the older generation models.

How to choose a gaming CPU?

How much your gaming PC or gaming laptop is going to be able to handle depends on the computer processor you end up buying. Before you blindly purchase the cheapest or the most expensive one out there, consider these factors and possible specifications:

• Cores. As we pointed out earlier, the more cores a CPU has, the more tasks it can perform simultaneously. While it might seem like buying the one with the most cores is the best choice, keep in mind that all the extra cores will be wasted if the software you use only utilizes half of them;
• Cache. It is temporary storage that is used to quickly retrieve various files – the larger the cache, the more files can be stored in it;
• Socket compatibility. If the CPU is not compatible with the motherboard, you simply won’t be able to install it – always check if these two components are compatible;
• Integrated GPU. Some computer processors have integrated GPUs but they are usually good enough for more simple tasks – if you’re planning on using graphics-intensive programs, it will simply not be enough and you will encounter problems;
• Frequency. This indicates the speed at which the processor operates – less intense games will work fine with a lower frequency while more demanding ones will require much more. Check the suggested specifications of the games you plan to play and try to match them up;
• Thermal design power. The CPU generates heat and the chip can overheat if it doesn’t get sufficient cooling – the thermal design power indicates the maximum amount of heat this component can generate. Depending on this, you need to also install an appropriate CPU cooler. Some processors come with coolers, while in other cases you have to buy one yourself.

Generally, it’s a bit tricky to say what is the best CPU to buy because it greatly depends on what each specific person needs from their PC build. While certain models exceed expectations, like Intel Core i5-11600K or AMD Ryzen 5 5600X, not every custom gaming PC needs these high-end CPUs if they can’t fully utilize everything they can do. Sometimes it’s better to buy a budget gaming CPU, especially since you pay less and can upgrade it once you feel like you need something more powerful.

Which CPU to pick – AMD or Intel?

For people looking for either the best processor for PC or a cheaper budget gaming CPU, 2 companies stood out as the most trusted CPU manufacturers for years – AMD and Intel. Although these companies work on developing the same hardware, there are significant differences between the chips they produce:

• The price and what you get. AMD offers PC processors at a lower price – they also usually include full overclockability on most models and complementary software. Intel CPUs, on the other hand, are a bit more expensive and usually include integrated GPUs with Quad-core processors and up;
• Performance. Intel processors are more suited for heavy tasks, like video editing, 3D graphics design and, in this case, gaming while AMD is more oriented towards multitasking. Either way, higher-end CPUs made by both are well-suited for gaming;
• Overclocking. Intel provides much more overclocking headroom and a significant performance boost while AMD’s chips don’t reach the same high frequencies;
• Power consumption & heat. The higher the consumption, the more powerful the cooler has to be to make sure the chip doesn’t overheat. Because Intel’s CPUs are geared towards providing the best performance, they generally produce more heat and consume more power while AMD’s models are a bit more efficient, consume less power and thus require simpler cooling solutions.
