Compare video connectors, display panels, memory modules, processors, and hardware bus protocols.
HDMI is designed primarily for home entertainment, TVs, soundbars, and gaming consoles, offering universal consumer electronics support with audio return (eARC). DisplayPort is engineered for PC monitors and workstations, providing higher raw bandwidth, monitor daisy-chaining (MST), and latching connectors.
OLED uses self-emissive organic pixels that turn off individually for infinite contrast and perfect black levels, ideal for dark rooms. QLED is an advanced LED-LCD panel enhanced with quantum dots that achieves significantly higher peak brightness and eliminates burn-in risk, making it superior for sunlit rooms.
USB-C is a physical connector shape and open hardware standard with varying speed capabilities (from 480 Mbps up to 40 Gbps). Thunderbolt (versions 3, 4, and 5) is Intel's proprietary protocol that uses the exact same USB-C shape but guarantees strict minimum data speeds, external GPU support, and dual 4K display output.
SATA SSDs use an older storage interface capped at approximately 550 MB/s due to legacy drive controller limits. NVMe (Non-Volatile Memory Express) SSDs communicate directly with the motherboard via high-speed PCIe lanes, achieving speeds between 3,500 MB/s (Gen 3) and 14,000 MB/s (Gen 5) with dramatically lower latency.
DDR4 operates at lower base speeds (2133 to 3600 MT/s) with a single 64-bit channel per stick, making it budget-friendly for older motherboards. DDR5 starts at 4800 MT/s, features dual 32-bit internal subchannels, on-die ECC error correction, and integrated PMIC power management for high-end gaming and heavy workstation multitasking.
Wi-Fi 6 operates exclusively on the crowded 2.4 GHz and 5 GHz frequency bands shared with legacy devices. Wi-Fi 6E unlocks the brand-new, uncongested 6 GHz spectrum with up to 1,200 MHz of additional bandwidth, eliminating legacy interference and providing ultra-low latency for VR headsets and gigabit fiber connections.
IPS (In-Plane Switching) panels excel in color accuracy, consistent viewing angles, and rapid pixel response times, making them the standard for color grading, office work, and competitive esports. VA (Vertical Alignment) panels provide 3 to 4 times higher native contrast ratios and deeper blacks, making them ideal for immersive dark-room gaming and curved screens.
Optical mice use an infrared or red LED illuminator to capture surface tracking, delivering 1:1 raw accuracy without hardware acceleration on mousepads. Laser mice use a coherent laser beam that tracks deeper surface micro-textures, enabling them to track on glass tables and glossy desks, but introducing minute jitter at high gaming speeds.
Intel Core i7 processors offer 16 to 20 hybrid cores with high clock speeds, delivering peak performance for AAA gaming and general software development without extreme cooling requirements. Core i9 processors add extra Efficiency cores (24 total), higher Thermal Velocity Boost frequencies, and larger L3 caches, designed for heavy 4K/8K video rendering, 3D simulation, and extreme workstation workloads.
Mechanical keyboards feature individual physical spring-loaded switches beneath each keycap, delivering distinct tactile feedback, n-key rollover without ghosting, and a lifespan of 50-100 million keystrokes. Membrane keyboards use a shared flexible rubber dome sheet over electrical contacts, producing silent, cushioned keystrokes at an affordable price point.
Passive noise isolation blocks sound physically using dense foam earcups, silicone ear tips, and clamping pressure without electronics or battery power. Active Noise Cancellation (ANC) uses exterior microphones to analyze incoming ambient sound waves and generates an inverted phase-reversed waveform ('anti-noise') that cancels the noise electronically.
Raster graphics are grids of fixed-color pixels (JPEG, PNG, GIF) that capture rich photographic textures but pixelate and blur when enlarged. Vector graphics are mathematical formulas of points, lines, curves, and fills (SVG, EPS, AI) that scale infinitely to any billboard size without losing crispness.
