Important CPU Key Terms

There are many technicalities revolving around CPUs. Here are a few key terms to look out for whenever you’re searching for a CPU:

  1. Cores: The actual execution of tasks and computation falls on the cores’ shoulders. A good gaming CPU should have 8 or more cores. 
  2. Threads: Applications or programs issue logical instructions known as threads to the CPU cores for execution.
  3. Multi-Threading: Multi-Threading (AMD) or Hyper-Threading (Intel) allows a single CPU core to execute two or more threads simultaneously.
  4. Cache: The cache is a little chunk of quick memory that is permanently attached to the CPU die. The cache is divided into three levels: L1, L2, and L3. L1 cache is the fastest and closest to the CPU, but it also has the smallest capacity. 
  5. Clock Speed: The amount of data cycles a processor can perform in a second is known as its clock speed. The base clock is the speed the processor will operate at all times, and the boost clock is the speed it will operate at under high workloads.
  6. TDP: The amount of heat generated by a processor is called its TDP. The TDP number indicates the type of CPU cooler you need. The higher the TDP, the more heat the CPU will generate, and hence, you will need a bigger cooler.
  7. Overclocking: By giving additional power to the CPU, you can have it run at clock speeds higher than its stock settings.

How We Picked The Best CPU For RX 7900 XTX & RX 7900 XT

To ensure that the CPU I recommend you are undoubtedly the best for these graphics cards, I evaluated them over several factors.

Similarly, whenever buying a processor, make sure you also consider these factors to make the right purchase decision.

  • Performance: I ran several gaming and productivity tests to judge the performance of each CPU. This way, I had a clear picture in mind as to which processors pack the necessary performance to go with the RX 7900 XTX/XT. Similarly, whenever you’re buying a processor, make sure to search for its benchmarks and tests to analyze its performance.
  • Value For Money: If you are ever in the market for processors, make sure to do thorough research into similarly priced processors and compare them based on their performance and other stats. This way, you will get the best bang for the buck CPU.
  • Power Consumption and Thermal Efficiency: High power consumption equates to high temperature, which ultimately means more AIO expenses. Well, if you are after a performance-centric build, then there is not really an escape from high temps, and you will have to go for a good quality CPU cooler.
  • Overclocking: I also tested the overclocking potential of my recommended processors. I overclocked these processors to determine the maximum stable clock speeds I could achieve, and now you also have an idea of how much performance you can get out of your CPU.
