Study Notes

Overview of Hardware

Hardware encompasses all physical components of a computer system, including the processor, memory, storage, communication interfaces, display, and power supply.
Desktop PCs have various hardware components, which can be explored through dedicated hardware guides and PC build videos.

Processor

The processor, or microprocessor, acts as the central processing unit (CPU) performing digital computations.
Key specifications: Instruction Set Architecture (ISA), clock speed, core count, multithreading, and cache.

Instruction Set Architecture (ISA)

ISA refers to the set of instructions the processor understands; the primary types are x86 and ARM.
The x86 architecture was pioneered by Intel, evolving from 16-bit to 32-bit and now to the current 64-bit (AMD64, x86-64, x86_64, or x64).
x86 is often used generically to denote both 32-bit and 64-bit architectures, although 32-bit x86 processors are no longer produced.
Both Intel and AMD produce 64-bit x86 processors under a licensing agreement.

ARM Architecture

ARM processors are developed by ARM Limited and licensed to various manufacturers, dominating Android and iOS devices.
Apple's M1 and M2 series of processors are based on ARM architecture, marking a shift from x86 to ARM for their devices.
ARM is increasingly prevalent in desktop and laptop computing, particularly in Apple’s hardware.

RISC-V Architecture

RISC-V is a developing ISA that is being recognized as a potential future competitor to x86 and ARM.
By 2025, it is anticipated that computers (end-user and server) will primarily utilize x86, ARM, or RISC-V ISAs.

Clock Speed

Measured in gigahertz (GHz), clock speed indicates how many instructions a processor can execute per second; typical speeds range from 1.5GHz to 5GHz.
Processors usually have a base clock frequency and a turbo/boost frequency for enhanced performance under optimal conditions.

Core Count and Multithreading

Core count refers to the number of individual processing units within a CPU, dictating how many tasks can be processed simultaneously.
Multithreading allows a single core to run multiple threads; Intel employs hyper-threading, while AMD uses simultaneous multithreading (SMT).
Commonly, multithreading can double the thread count (e.g., a quad-core CPU can handle eight threads), with some processors supporting four-way multithreading.
