Here are the key differences between integrated motherboards and pin-type motherboards:

Definition & Design Idea:

• Integrated motherboards (all-in-one motherboards) integrate core components like CPU, graphics card (integrated/core graphics), sound card, and network card directly onto the board. They prioritize high integration and miniaturization.
• Pin-type motherboards feature removable CPUs, with pin-type CPU sockets (e.g., Intel LGA series, AMD AM4). Users need to buy and install compatible CPUs separately; functions like graphics/sound cards often require expansion cards.

CPU Connection:

• Integrated motherboards mostly use BGA packaging—CPU is soldered to the board, non-removable/replaceable.
• Pin-type motherboards use pin-type sockets; CPUs can be plugged/unplugged and replaced (if compatible with the socket).

Function Integration:

• Integrated motherboards have high integration: they must include CPU, core graphics, sound/network cards (some even on-board memory or Wi-Fi/Bluetooth), and work without extra basic components.
• Pin-type motherboards have basic integration: only sound/network cards (some lack wireless modules); CPU, graphics card (if needed), and memory require separate purchase and installation.

Expandability:

• Integrated motherboards have poor expandability: fixed on-board memory (or 1 slot), 1-2 storage interfaces, few/no PCI-E slots (no discrete graphics/expansion cards).
• Pin-type motherboards have good expandability: 2-4 memory slots (supports upgrades), 2-4 SATA + 1-2 M.2 interfaces (multiple hard drives), 1-3 PCI-E slots (for discrete graphics/expansion cards).

Applicable Scenarios:

• Integrated motherboards suit lightweight, mini, low-cost needs: mini hosts (home audio-visual, office mini PCs), embedded devices (industrial control), entry-level all-in-ones/thin clients.
• Pin-type motherboards suit flexible customization/upgradeable performance: desktops (gaming, workstations), upgradeable Mini-ITX hosts, commercial office PCs (later memory/hard drive expansion).

Maintenance & Upgrade Costs:

• Integrated motherboards have high/limited costs: CPU failure may need motherboard replacement; core components can’t be upgraded.
• Pin-type motherboards have low costs: faulty components are easy to replace; CPU/memory can be upgraded alone.

Size & Power Consumption:

• Integrated motherboards are small (Mini-ITX/Nano-ITX), with low-power CPUs (e.g., Intel Celeron N4100, TDP 6W) and no complex cooling.
• Pin-type motherboards are larger (ATX/Micro-ATX; even Mini-ITX is bigger); power consumption depends on components (higher performance = more power, needs cooling).
