A PC assembly is arguably one of the most difficult endeavours, due in part to the vast selection of components numbering in the millions. During this procedure, the processor emerges as the most critical element due to its ability to regulate all other components and ascertain the performance of the system. Unfortunately, due to the adoption of perplexing nomenclature conventions and options by Intel and AMD, purchasing a processor in the twenty-first century is anything but simple. As a result, the following is an exhaustive guide to all the information you require prior to purchasing a new CPU.
Threads and cores
Due to the fact that cores symbolise discrete processors capable of executing a solitary task, the number of cores is directly correlated with performance. The quantity of concurrently operable duties that a CPU can manage is denoted in threads. Furthermore, concurrent multithreading enables processors to employ unused core resources for supplementary operations, thereby elevating the importance of threads and core count in the process of selecting a central processing unit. Nevertheless, in general, a greater quantity of threads and cores is preferable.
Cache, IPC, and Clock Speed
An additional critical consideration when selecting a CPU is its clock speed, which is denoted in gigahertz (GHz) or megahertz (MHz). It indicates the rate at which a processor is capable of performing tasks per second. Conversely, ratings pertaining to instructions per clock (IPC) indicate the quantity of operations that a central processing unit (CPU) is capable of carrying out within a single clock cycle.
Lastly, the cache of the CPU, which functions as directly incorporated, accessible memory in the processor, is an additional crucial purchasing consideration. L2 cache is typically allocated to a single CPU core, whereas L3 cache is shared by all CPU cores. In essence, an increase in clock speed, IPC, and cache corresponds to an improvement.
TDP
Thermal Design Profile/Power, or TDP, refers to the utmost heat output that a processor is capable of producing during a specific task. TDP is an essential component because it has a direct effect on the power consumption, which can be a significant factor in regions with high electricity costs. It is measured in watts. Users should therefore consistently verify the TDP of their processor and all other components prior to purchase.
Comparing Intel and AMD

The Intel versus AMD controversy is an age-old dilemma. Although Intel emerged victorious approximately five years ago, the situation is considerably more intricate at present. The selection is contingent upon one’s particular workflow and requirements.
Although it is impossible to anticipate the specific requirements of every individual, a comparative analysis of the products and services provided by both organisations is possible. With an astounding 24 cores (8 + 16) and support for up to 32 threads, the Core i9-14900K from Intel competes with the Ryzen 9 7950X3D from AMD among the flagship offerings. In contrast to its more conventional 16-core and 32-thread configuration, the latter incorporates a cache for its gaming X3D processors.
With the introduction of the X3D technology, Intel surpasses Team Red in productivity duties, whereas AMD outperforms Team Blue in gaming.
However, since the majority of us do not wish to spend more than $500 on a new CPU, we shall examine the more affordable options. At a more affordable price point, Intel’s Core i5 14600K and even the previous generation’s i5 13600K have established a niche for themselves by providing exceptional gaming and productivity performance. Although AMD’s Ryzen 5 7600 provides marginally superior performance, its requirement for DDR5 RAM substantially escalates the overall cost of the configuration.
Even on an even more limited budget, both Intel and AMD offer CPUs from the previous generation. At approximately $100, the i3-13100F is in competition with the six-core Ryzen 5 5500 from AMD, which costs around $120 and provides similar performance in gaming scenarios.
Best CPUs according to cost
Despite the numerous explanations, selecting the optimal CPU for your construct can remain difficult due to the variety of available options. Therefore, let’s classify the top CPUs according to their prices:
Roughly $100

An excellent option for those on a limited budget is the Intel Core i3-13100F. It features twelve threads and six performance cores operating at a base clock rate of 3.4 GHz and a turbo clock rate of 4.5 GHz. Supporting DDR5 RAM and 12MB of L3 cache, it is an uncomplicated option for a frugal construction.
Below $200

The Intel Core i5-13400K, which costs approximately $228, is arguably the most cost-effective processor on the market. It is composed of four efficiency cores operating at a maximum speed of 3.3 GHz and six performance cores operating at a base clock rate of 2.6 GHz with a boost clock rate of 4.6 GHz. It is a 7% speedier alternative to AMD’s Ryzen 5 7600 and supports DDR4 RAM, making it an ideal option for consumers upgrading an older system.
Below $400
CPU: AMD Ryzen 7 7800X3D
Within this specific price range, the AMD Ryzen 7 7800X3D emerges as the dominant product, surpassing the offerings of Intel and even outperforming certain high-end processors from AMD. The approximately $449 chip features eight processors operating at a base frequency of 4.2 GHz and a boost frequency of 5.0 GHz. However, in contrast to Intel, it performs less efficiently in duties pertaining to productivity, despite its exceptional performance in gaming.
