What is commonly done to increase the performance in low-end CPUs?

Overclocking is a method used to increase the performance of low-end CPUs by running the processor at a higher clock rate than it was originally designed for. This can enhance the processor's performance for tasks that rely heavily on CPU processing power. By increasing the clock frequency, the CPU can execute more instructions per second, leading to faster performance in applications that are CPU-bound.

However, it's essential to note that overclocking comes with risks, such as increased heat generation and potential system instability. Proper cooling solutions must be in place, and not all CPUs support overclocking features.

Increasing the amount of RAM, while beneficial up to a certain limit, does not inherently boost CPU performance; it primarily allows the system to handle more applications simultaneously. Replacing the CPU can yield significant performance improvements but is often impractical for low-end systems due to compatibility issues and cost. Using a solid-state drive (SSD) enhances system responsiveness and decreases data access times, but it primarily benefits overall system performance rather than directly affecting CPU operations.
