In the world of computer hardware, terms like PCH and SoC can sound like technical jargon. Understanding these two architectures is vital if you're creating a PC, purchasing a laptop, or wondering why smartphones are so tiny. Although both serve as the "command center" for your device's components, they operate in distinct ways. Let's look at the distinctions between Platform Controller Hub (PCH) and System on a Chip (SoC) technologies.
What is a PCH (Platform Controller Hub)?
The PCH is a specific chip on a motherboard that facilitates communication between the CPU and slower system components. Historically, motherboards featured a "Two-Chip" chipset, with the Northbridge (for high-speed RAM and graphics) and the Southbridge (for slower USB and storage). Modern Intel and AMD systems have consolidated the Northbridge functions into the CPU, allowing the PCH to handle the remaining tasks.
Essential Functions of a PCH:
Connectivity: Oversees USB ports, SATA drives, and integrated audio.
Networking: Regulates Ethernet and Wi-Fi connections.
Expansion: Manages PCIe lanes for additional peripherals such as sound or capture cards.
What is SoC (System on a Chip)?
A SoC is a "all-in-one" powerhouse. Rather than having a CPU and a separate PCH chip, a SoC combines practically everything—the processor, graphics (GPU), memory controller, and I/O—onto a single silicon die. SoCs can be found in devices where size and battery life are critical, such as smartphones, tablets, and current ultra-thin laptops (such as Apple M-series MacBooks).
Essential Functions of a System on Chip (SoC):
High Integration: Incorporates CPU, GPU, and RAM controllers into a single unit.
Energy Efficiency: Minimizes data travel distance, extending battery life.
Compact Design: Removes the requirement for a bulky, complicated motherboard.

Which one is right for you?
If you are a gamer or a professional video editor, consider PCH-based devices. These systems enable increased "overhead," improved cooling, and the capacity to replace parts as technology advances.
If you require a gadget that is extremely light, cools down without a loud fan, and lasts all day on a single charge, go with SoC-based platforms.
