Modern CPUs are versatile for gaming, creating content, and more, but sometimes specialized chips like ASICs are preferred for specific tasks. ASICs are Application Specific Integrated Circuits designed to perform specific calculations or algorithms for one application. They are hardwired and can be semi-custom or fully custom designs. ASICs are cost-effective for small, highly integrated devices like USB chargers or network switches. ASIC-based crypto miners are expensive but efficient for cryptographic hashes.
