Study Notes
Memory
- RAM is measured in Megabytes (MB) and Gigabytes (GB), with the required amount depending on software needs.
- Windows XP requires a minimum of 1 GB RAM; Windows 7 requires at least 2 GB.
- Performance attributes of memory include:
- Speed (measured in MHz)
- Timing (CAS - Column Access Strobe)
- Voltage
- Typical memory speeds for DDR4 range from 2133 MHz to 3200 MHz.
- Example DDR3 Technical Specifications:
- Speed Grade: 1333 Mbps
- Unbuffered DIMM: 240-pin
- CAS latency: 9-9-9
- Bandwidth: 10660 MB/s
Processor
- The CPU conducts calculations and processes instructions from the operating system.
- Clock speed denotes processor speed, typically in gigahertz (GHz), with modern processors reaching up to 4.7 GHz.
- Key criteria for selecting a processor:
- Cores: Ranges from dual-core to 8-core, with options including Core 2, i3, i5, and i7.
- Cache: Fast memory in MB, with low-end processors having around 0.25 MB and high-end processors up to 24 MB.
- Socket compatibility: Ensure compatibility between the motherboard and CPU after purchase.
- Integrated GPUs: Provides graphics processing; optional if a separate graphics card is present.
- Frequency: CPU speed; potentially lower frequency CPUs may outperform higher frequency counterparts due to architecture efficiency.
- Front Side Bus (FSB): Communication link between CPU and memory, measured in Hz, ranging from 66 MHz to 800 MHz or higher.
- Example of Intel® Core™ i5 Processor Specifications:
- Product Collection: 7th Generation i5
- Number of Cores: 4
- Max Turbo Frequency: 3.50 GHz
- Cache: 6 MB SmartCache
- TDP: 65 W
- Number of Threads: 4
- Bus Speed: 8 GT/s DMI3
- Base Frequency: 3.00 GHz
Video Card
- Known as graphics card or display adapter, connects to motherboard and processes images/videos.
- GPU efficiency determines the speed and visual quality, measured by frame rate (FPS).
- Human perception processes about 25 FPS; fast games typically require a minimum of 60 FPS for smooth visuals.
- Frame rate elements include:
- Triangles per second: Measures how fast the GPU can render polygons for 3D images.
- Pixel fill rate: Indicates how quickly the GPU can process image pixels.
- Key hardware specifications affecting graphics card speed:
- GPU clock speed (MHz)
- Size of memory bus (bits)
- Amount of memory available (MB)
- Memory clock rate
