Desktop Computer Dissection

Introduction

• The video presents a 3D animation-based dissection of a desktop computer.
• The process involves exploring and disassembling each piece of hardware.
• Captures a nanoscopic view of transistors and structures inside.

Computer Disassembly Process

• Desoldering Components: Hardware inside a typical desktop computer disassembled.
• 3D Modeling: Thousands of pictures taken; 3D model of each component created.
• Exploration begins with the CPU and moves onto other components.

Central Processing Unit (CPU)

• Structure: Cover (integrated heat spreader), integrated circuit (die), mounted on PCB.
• Connection: 1200 connection points interface with a landing grid array on the motherboard.
• Components:
  • 10 cores for program and instruction execution.
  • Shared L3 memory cache and ring interconnect.
  • Integrated graphics processor.
  • Memory controller for DRAM data management.
  • System agent and platform I.O.
• Transistors: ~8-10 billion, layered with metal wires to form a highway for operations.

Motherboard

• Components: Massive PCB with wires, microchips, sockets, ports, etc.
• Chipset: Connects with CPU's system agent, manages most data flow.
• Voltage Regulator Module (VRM): Manages voltage from power supply for CPU.

Power Supply

• Function: Distributes power, voltage reduction via transformer.
• Components: Control PCB, switching power transistor, opto-isolators.

Cooling System

• CPU Cooler: Liquid pump circulates coolant through radiator and fins.
• Pump Structure: Brushless DC motor with no mechanical connection to prevent leaks.

Graphics Processing Unit (GPU)

• Structure: PCB with integrated circuit, VRAM chips, voltage regulator.
• Components:
  • 11.8 billion transistors, 6 graphics processing clusters.
  • Streaming multiprocessors (128 cores each).
  • L2 memory cache, memory controllers for VRAM, PCIe interface.
• Comparison with CPU: Thousands of simple cores for arithmetic operations.
• Parallel Processing Example: Faster image processing vs. CPU due to more cores.

Data Storage

• DRAM: Direct CPU communication, temporary data storage using 1T1C memory cells.
• Solid-State Drives (SSD): Permanent data storage in 3D NAND arrays.
• Hard Disk Drives (HDD): Slower storage, uses magnetic disks.

Peripheral Hardware

• Computer Mouse: Components include scroll wheel, infrared light, image sensor.
• Keyboard: Plastic traces carry electricity, processor senses keypresses.
