Cheat Sheet
- CPU Performance & Amdahl's Law -
Understanding cores versus threads is key when you test pc hardware performance; cores handle tasks while threads allow parallel processing. Use Amdahl's Law (S = 1 / ((1 - P) + P/N)) to estimate speedup when part of a workload is parallelized (source: MIT CSAIL). Remember: even with many cores, a non-parallel task (1 - P) limits overall gains.
- DDR Memory Speeds & Latency -
The "DDR" in RAM stands for Double Data Rate, transferring data on both clock edges; DDR4-3200 runs at 3,200 MT/s. JEDEC standards define timings like CL16, where lower CL (CAS Latency) means faster RAM response (source: JEDEC.org). Mnemonic: "More data, more dates" helps you recall that higher MT/s leads to smoother multitasking.
- Storage Types: HDD vs SSD vs NVMe -
When you test computer hardware storage, know that HDDs use spinning platters (~100 - 200 MB/s) while SATA SSDs hit ~550 MB/s, and NVMe SSDs on PCIe x4 can reach up to 3,500 MB/s (source: Samsung whitepaper). Identify form factors - 2.5″ vs M.2 - and interfaces to match your build. Tip: "Spin, SATA, Speed" helps memorize ascending performance tiers.
- Motherboard Form Factors & Chipsets -
ATX, micro-ATX, and ITX determine your build's size and expansion slots; full-size ATX offers up to seven PCIe slots, while mini-ITX fits in compact cases (source: Intel® ARK). Chipsets like Intel Z690 or AMD X570 dictate overclocking, PCIe lanes, and USB ports. Quick guide: "Form Factor = Fit, Chipset = Features."
- GPU Architecture & VRAM -
Graphics cards use a dedicated memory bus (e.g., 256-bit) to shuttle texture data between GPU cores and VRAM; higher bus width plus GDDR6 speeds means better frame rates (source: NVIDIA developer docs). Know that more VRAM helps in high-res gaming and GPU-accelerated compute tasks. Remember: "Wide bus, smooth fuss" to link bus width with performance.
