Which CPU is best for bitcoin mining?

With the rapidly evolving world of cryptocurrency mining, many enthusiasts are asking: "Which CPU is best for Bitcoin mining?" The answer, quite frankly, is that the CPU is not the ideal choice for Bitcoin mining anymore. Bitcoin mining has shifted heavily towards utilizing Graphics Processing Units (GPUs) and, more recently, Application-Specific Integrated Circuits (ASICs). However, if one is insistent on using a CPU, it's crucial to consider factors like clock speed, core count, and cache size. Intel's high-end Core i9 or AMD's Ryzen Threadripper series tend to offer the best performance, but bear in mind that even the fastest CPUs are dwarfed by the mining power of modern GPUs and ASICs. Additionally, it's important to factor in electricity costs, as CPU mining tends to be less efficient and therefore more expensive.
