Understanding the differences between CPU, GPU, and APU

Most of the hardware in your PC is associated with an acronym, and as technology advances and the number of parts increases, keeping all those names straight can be disruptive. For the sake of keeping it all straight and to potentially help yous go the hardware yous need, let's take a look at the differences between the terms CPU, GPU, and APU.

What is a Cardinal Processing Unit of measurement (CPU)?

The CPU can be considered the brain of your PC. It has a manus in pretty much all tasks and calculations carried out from all hardware, making it essential to your device'south health and performance. Near modern PC CPUs employ multiple cores to handle multiple tasks at once, and overall performance is measured in gigahertz (GHz). For example, if a CPU has a base clock speed of 2.4GHz, it should be able to procedure up to 2.iv billion instructions in a 2d.

When it comes to CPU manufacturers, you'll likely hear about Intel and Advanced Micro Devices (AMD). Both create products that tin run Windows, and, especially at present that AMD has Ryzen, there'southward a shrinking gap between the two companies when it comes to cost and performance.

Operation does vary quite widely beyond all CPUs from both manufacturers, offering up plenty of options when it comes to price and power consumption. Yous tin detect a depression-performance CPU that'south keen for word processing, spider web browsing, and battery life, while you can besides discover a high-operation CPU that will absolutely shred anything you throw at it merely will likewise suck up power similar a vacuum in comparison.

We've written extensively about CPU technology and choosing the right CPU for your PC, and so be sure to check out these links for more than information.

What is a Graphics Processing Unit of measurement (GPU)?

The GPU in your PC is substantially responsible for what you lot run into displayed on the monitor(s) continued to your PC. At that place are typically two types of GPU: integrated and dedicated (also called discrete). Integrated GPUs share space with the CPU'southward chipset, while dedicated GPU'south are a separate piece of hardware connected to a divide bus.

A GPU is designed to focus on large jobs that crave a lot of power. Intensive gaming, VR, and video editing are all tasks associated with GPUs, thanks to the high number of cores bachelor. While the CPU is the captain of your PC'southward team, the GPU can exist considered the grunt, ready to accept the most strenuous jobs.

What is an Accelerated Processing Unit (APU)?

APU is a term that AMD came upwards with to denote a GPU integrated into a CPU'due south compages. Both the graphics processing cores and the standard processing cores share the same cache and die, and information is transferred through the same charabanc.

Why create an APU? Having both the CPU and GPU in the same spot allows them to piece of work more efficiently for increased processing power. Besides, having the GPU and CPU integrated is usually more energy efficient than having a CPU and a carve up, dedicated GPU. Many modern APUs are powerful enough for non-intensive gaming; however, an APU will almost e'er be trumped by a modern defended GPU.

The first APU, using codename Llano, was announced by AMD dorsum in 2022, merely the project had been in the works since about 2006. If you're wondering where Intel stands in all this, most of their CPUs besides employ integrated graphics. For example, the Intel Cadre-i7-8700K, commonly paired with a powerful dedicated GPU, does take Intel UHD Graphics 630 built right in. The term APU, all the same, isn't used by Intel, likely due to the heavy connexion with AMD.
