Geekbench is a cross-platform benchmarking tool designed to measure the performance of computer processors and systems. It evaluates both single-core and multi-core performance, providing a score that helps users compare the capabilities of different devices, such as smartphones, tablets, and laptops. The software runs a series of tests that simulate real-world tasks, including image processing and machine learning. Users can easily access their scores online, allowing them to see how their devices stack up against others in the market. This makes Geekbench a valuable resource for consumers and developers alike.
