The processor is a vital component in every gaming PC and laptop. If you don’t have one, your device just won’t work. Straight off the bat, we can see that processing power is important.
It pays to give some thought to the processor you choose. A poor chip will hinder every single aspect of your machine, while a high-quality processor could take your gaming, work, and daily computing to the next level. In this article, we’ll be investigating how CPUs work, what the cores do, as well as showcase some popular models currently on the market – including some of our very own overclocked motherboard bundles. Plus, we have some more detailed guides on the latest generations of processor for your further reading.
Like Clockwork:
A CPU works by interpreting instructions from your operating system, commonly Windows 11 or Windows 10 in gaming PCs. It will access programs, move data between components, and manage memory; co-ordinating your entire gaming PC. Anything that can improve their decision making is vital. This is why we’ve seen recent innovations like Intel’s Thread Director.
It’s useful to know how processors work at a component level. This knowledge won’t necessarily inform your buying decision, however, as all CPU possess this functionality regardless of performance tier. This is where understanding the key concepts behind processors comes into play.
Clock speed is a great starting point and a crucial aspect of CPU performance. This term refers to the number of electronic pulses per second that the CPU can process. It’s measured in GHz, equating to billions of pulses per second. Base clock speeds are often displayed in the processor’s product title, as shown below.
The higher this number, the more pulses can be completed. As a result, your tasks get finished quicker. High clock speeds are something to look for when purchasing a CPU. There are things you can do to boost performance. Overclocking increases the clock speed of your processor. This can be achieved with specialist software, such as AMD Precision Boost 2 (PBO2) and Intel Extreme Tuning Utility (Intel XTU). This software can be utilised to dynamically overclock your CPU, either with easy-one click profiles or manual settings, enabling the best performance from your processor, provided your PC has the thermal headroom to support this. More speed equals more heat.
It should also be noted that CPUs overclock differently, due to variances in the silicon. No two models perform the same when pushed.
The Core Issue:
The number of cores and threads a processor has is another key factor in deciding on which CPU is best for you. The number of cores generally denotes what sort of gaming and content creation the CPU is able to handle. Both Intel and AMD have a nicely tiered system that is easy to interpret and match to your needs. As a general rule of thumb, the more demanding your work, the more cores your processor should have.
Back to basics, every CPU is divided into smaller processing units, called cores. Each is capable of handling a computing task. Entry-level processors, such as Intel Core i3/i5s and AMD Ryzen 5s, will have a low core count, typically four to six cores. High-end processors, like the Intel Core i9 and AMD Ryzen 9, have much higher core counts, possessing sixteen or even twenty-four cores. Intel Core and AMD Ryzen are both great series for gaming, streaming, and content creating. If you are crafting a workstation PC for more intensive workloads, then there are series with even higher core counts, such as the AMD Threadripper and Intel Xeon CPUs.
Most modern processors also support multi-threading and Hyper-Threading, which allows the core to double the number of instructions it can process. Effectively, this doubles your core count.
A lot of popular games have four-core CPUs in their recommended specifications, so a higher core count isn’t necessarily needed for gaming. This enables you to pick CPUs that are a little more budget-friendly. However, if you wanted to stream, multitask, or create content, opting for more cores is a necessity.
Of course, a lot goes into craft the spec of your gaming PC. Check out all our content that will help you through this process with our Ultimate PC Building Guide.
The Current Market:
Currently, the CPU market is all about 13th Gen Intel and AMD Ryzen 7000 Series. Both Intel and AMD launched their latest generations towards the end of 2022 and have had subsequent models release since. For instance, the AMD X3D models with 3D V-Cache became available in April. As such, we have a CPU market primed with juicy new tech and innovations – plenty of choice for you!
Here is a quick comparison table of the Intel Core i9-13900KF and AMD Ryzen 9 7950X processors.
| Feature | Intel Core i9-13900KF | AMD Ryzen 9 7950X |
|---|---|---|
| Cores | 24 (8P + 16E) | 16 |
| Threads | 32 | 32 |
| Unlocked | Yes | Yes |
| Cache | 68MB | 80MB |
| Clock Speed | 3.0GHz | 4.5GHz |
| Boost Speed | E – 4.3GHz / P – 5.4GHz | 5.7GHz |
| TDP | 125W | 170W |
| Socket | LGA1700 | AM5 |
We’ll take a closer look at each gen’s specifics next.
13th Generation Intel Core
13th Gen Intel, otherwise known as Raptor Lake, builds on the hybrid core architecture first established in 12th generation Intel processors, Alder Lake. This architecture has two different kinds of cores: Performance (P-cores) and Efficient (E-cores).
P-cores are the heavy lifters, designed to handle the single-threaded work. It has significantly improved frequency control whilst improving performance potential. E-cores are designed to manage the smaller, background tasks. Lighter workloads are spread across multiple cores and threads, allowing for greater efficiency. Improving upon Alder Lake’s foundation, this generation features more E-cores as well as a significant uptick in both multi- and single-threaded performance.
What’s more, 13th Gen Intel has support for DDR5 RAM, PCIe Gen 5, and boost speeds up to 5.8GHz. Utilising the LGA1700 socket, these CPUs are compatible with Z790 and B760 chipsets, as well as select Z690 chipsets, but this is down to motherboard manufacturers providing BIOS support.

AMD Ryzen 7000 Series
The AMD Ryzen 7000 Series is built upon AMD’s Zen 4 architecture. This is a five-star platform, providing support for DDR5, PCIe 5.0 for graphics and storage, 5.0GHz+ boost speeds, a new socket called AM5, and built utilising an innovative 5nm process. All this brings a serious uptick in performance and energy efficiency in comparison to the previous generation, Zen 3.
What’s more, launched in tandem with the first round of CPUs, AMD has released a memory overclocking programme called AMD EXPO. This comprehensive software makes overclocking DDR5 RAM a breeze.
