Hyperthreading is a technology developed by Intel that allows a single physical CPU core to execute multiple threads concurrently. It essentially allows the operating system to see two virtual cores instead of one, which can improve the efficiency of CPU resource usage. By utilizing idle CPU time that would otherwise be wasted, hyperthreading increases throughput and performance for multithreaded applications. This feature is particularly beneficial for workloads that can run parallel tasks, enabling better utilization of the processor without requiring additional physical cores.

The other options focus on different aspects of processing. Throttling pertains to reducing the clock speed of the CPU to prevent overheating and save power, which does not relate to increasing the number of threads executed. Multicore processing refers to using multiple physical cores to execute multiple threads simultaneously, which is a distinct concept from what hyperthreading accomplishes. Cache memory, while critical for speeding up access to frequently used data, does not impact the number of threads executed but rather supports data transfer efficiency in processing.
