The first question you should ask yourself when choosing a CPU is.

What will I use my PC for?

It could be for gaming, work, or content creation. Different workloads benefit from different CPU strengths. So, you have to be totally honest with yourself and be realistic. 

Are you sure you’re not gonna play games with this new PC?
*Bombastic side-eye*

Because compared casual use/ office work with gaming, gaming requires more function as it need strong single-core performance and higher clock speeds. 

If you are trying to achieve Content Creation such as video, 3D rendering, or Streaming, you would want to seek processors with more Cores to achieve faster rendering and multitasking. 

And if you need a PC to do heavy multitasking or professional workstations, high core count & strong multi-threading is the way to go. 

Intel Core Ultra 7 265KF (20 Cores, up to 5.5 GHz)

Let’s use the processor above as an example for further explanation. 

🖥 What is Cores? 🖥

Core is refer as the primary processing unit of the CPU. Each Core can run one task at a time, so if a processor has multiple cores, it can execute multiple tasks simultaneously. Intel Core Ultra 7 265KF has 20 Cores as listed in their website, which means it can run 20 task at a time. 

The core count in a CPU tells you how many independent task it can handle at once, and the “threads” helps the CPU juggle jobs more smoothly. In simpler terms, it’s a set of instructions that can be executed by a CPU core. Threads are crucial for multitasking, allowing a single core to perform multiple task at the same time. 

HERE COMES THE BIG QUESTION! 

How Many Cores do you need?

Rule of Thumb:

🎮 6 Cores/ 12 threads is the sweet spot for gaming
🎨 8-12 Cores are great for creators and multitaskers

Intel Processors

• Strong single-threaded performance and higher clock speeds
• High boots clocks help single-threaded performance
• Consistent performance
• Hybrid core improve responsiveness

AMD Processors

• Offers more cores and threads at competitive prices
• Higher core count can benefit CPU-heavy games
• Gained popularity for its excellent multi-threaded performance and value for money

Depending on your expected performance and features, you are able to choose which brand you prefer.

Overclocking is the process of increasing a CPU’s clock speed beyond its factory settings to achieve higher performance.

⚙️ Pros

• Performance boost
• Great for enthusiasts who like tweaking

⚠️ Cons

• Generates more heat – have to ensure you have an adequate cooling solution
• Not all CPU supports overclocking 
• Might lead to shorten component lifespan if done poorly/

This is an important aspect because Not all CPU supports overclocking! If you’re going to need to overclock your CPU, you’ll need to look for Intel CPU that ends with “K”.

For exmple, i5-13600K 

As for AMD CPU, almost all desktop Ryzen CPU are unlocked, except for OEM-only CPUs, which are prebuilt systems with locked BIOS.

BALANCE IS THE KEY! If you’re going for a high-end GPU, you’ll need an equally powered CPU to match.

A GPU’s (Graphic Card) job include render graphics, visuals, textures, resolution, and frame rates; where as a CPU (Processor) handles game logic, AI, physics, background tasks, multitasking. They have to work together, if one is significantly weaker than the other, the whole PC’s performance is limited by the weaker part, which in this situation it is what we called – Bottleneck.

Your CPU and GPU should be balanced, so: 

• CPU can feed data fast enough and your GPU isn’t waiting.
• GPU is strong enough so that your CPU isn’t doing all the work.

So how do we avoid bottlenecks? There are many bottleneck calculator online that we can use as reference. These bottleneck calculator shall give you some advance notes on how the chosen GPU and CPU pair together overall and warn about any incompatibilities.

✅ Or just a quick and easy paring example:

• 🟢 Entry-level GPU (such as RTX3050, RTX4050, RTX5050 or RX6600/ RX7600)
  • Intel Core i3 (12th Gen and  above
  • Intel Core i5
  • AMD Ryzen 3
  • AMD Ryzen 5
• 🔵 Mid-Range GPU (Such as RTX4060/ 4060 Ti, RTX 4070, RTX 5060/ RTX5060 Ti or RX7700 XT/ RX 7800XT)
  • Intel Core i5/ Core Ultra 5
  • Intel Core i7 
  • AMD Ryzen 4
  • AMD Ryzen 7
• 🔴 High-End GPU (Such as RTX4080, RTX4090, RTX 5070 and above, RX 7900XTX)
  • Intel Core i7/ Core Ultra 7
  • Intel Core i9/ Core Ultra 9
  • AMD Ryzen 7
  • AMD Ryzen 9

Your CPU must match the socket and chipset of your motherboard.

Intel and AMD CPU has different sockets.

• Intel CPU match with Intel socket boards
• AMD Ryzen CPU match with AMD socket boards

One Thing to keep in mind here, is that overclocking supports also depends on board chipset too!

And that’s it! Phew~ This is a long chapter isn’t it? There so much more to learn about processors but I suppose this should be sufficient for now. 

Now just to sum this class up, the bottom line when choosing the right processor:
✅ Choose base on your task
✅ Make sure it fits your budget
✅ Check motherboard compatibility 
✅ Overclock only if you want extra performance and are comfortable with tweaking
