Key Differences
Multicore and Multiprocessor are terms that revolve around enhancing computational power. A Multicore CPU hosts several cores on a single chip, which means multiple tasks can run simultaneously on separate cores, improving performance and efficiency. On the other hand, a Multiprocessor system possesses more than one complete CPU unit, which can independently execute tasks.
The concept of Multicore emerged as a solution to increasing demand for faster computing without significantly increasing the clock speed, which could cause overheating. By adding more cores to a single CPU, tasks can be distributed and processed in parallel. Multiprocessor systems, however, have been around for longer and were an earlier solution to enhance processing by adding more CPUs to a system, each capable of handling tasks separately.
Multicore CPUs have become more common in modern personal computers and mobile devices due to their power efficiency and capability to handle multitasking seamlessly. Multiprocessor systems are typically found in high-performance workstations, servers, and supercomputers where maximum computational capability is essential.
In essence, while both Multicore and Multiprocessor aim to improve processing power, the former focuses on multiple cores within a single CPU, and the latter emphasizes multiple distinct CPUs in a system.
