Initially created to meet the demanding needs of modern video games, GPUs have shown exceptional capabilities across various sectors, including HPC and AI. Unlike CPUs, which handle general tasks sequentially, GPUs leverage parallel processing, utilizing their multitude of cores to excel in complex, data-heavy workloads.
Understanding GPU Architecture
GPUs consist of specialized multiprocessors connected via transistors, allowing them to perform multiple tasks simultaneously—hence their efficiency in parallel processing. They have independent RAM to manage the high volumes of data they handle, which enhances their speed and multitasking abilities.
Types of GPUs
- Discrete GPUs: Stand-alone chips independent from the CPU with dedicated memory, offering higher performance for intensive tasks at the cost of increased energy consumption and heat.
- Integrated GPUs: Built into CPUs, sharing memory with them, which is prevalent in many consumer devices due to their lower cost and power usage.
- Virtual GPUs (vGPUs): Cloud-based solutions offered by service providers, allowing enterprises to dispense with physical hardware.
Applications of GPUs
- High-Performance Computing: GPUs enable powerful computations necessary for supercomputers and extensive simulations in fields like weather forecasting and quantum mechanics.
