Processor cores and threads

Processor cores work, to some extent, like separate processors and can handle computational tasks independently of each other. This means that the more physical cores a processor has, the more tasks it can process simultaneously. Threads can be described as separate virtual cores, which all modern processors have. An eight-core processor typically has sixteen threads, so it can handle sixteen processes at once.
AMD processors

Processor frequency

The operating frequency indicates the speed of the processor. In general, a processor with a higher frequency can execute instructions faster than one with a lower frequency. A higher frequency ensures snappier and faster responses in everyday computer use, such as launching applications, browsing the internet or editing documents. It ranges from 1 to 5GHz. Some CPUs allow for a short-term frequency increase under heavy load (Turbo Boost).
AMD processors

L2 and L3 cache

To work as quickly as possible, the processor needs fast storage where it can save temporary data. The L2 and L3 cache, located directly on the processor, serves this purpose. While these memory caches are significantly smaller than RAM, they are also faster. L2 and L3 are the first storage the processor interacts with, and generally, the larger the better.
AMD processors

Processor socket

Before you choose a new processor, you should know which hardware connector (socket) your motherboard has for the CPU. The processor and motherboard must have the same socket designation; this is the first step towards a functional build. Another important factor is the type of RAM. You should know what type of RAM you have.

TDP (Thermal Design Power)

TDP (Thermal Design Power) is a processor parameter that indicates the amount of heat it produces at maximum load, while also suggesting its energy consumption. A lower TDP means the processor consumes less power and generates less heat, which is ideal for laptops or energy-efficient systems. Conversely, processors with a high TDP offer higher performance but require advanced cooling to prevent overheating.
AMD processors

Processor cooling

A processor, much like a graphics card, generates heat during operation that needs to be dissipated to keep the processor itself cool. Some chip packages already include a cooler, but if you want to be absolutely sure you can handle the processor's heat output, get an external one. External processor coolers come in various sizes and performance levels, and many support stylish RGB backlighting. You can get both classic air and modern liquid cooling options.
