Understand the Specs
Browse all terms →CPU Cache (L1, L2, L3)
Ultra-fast memory built into the CPU die that stores frequently accessed data. L1 is fastest and smallest; L3 is largest. Critical for gaming performance.
CPU Cores and Threads
A core is an independent processing unit within a CPU. Threads are virtual cores created via simultaneous multithreading (SMT/Hyper-Threading), allowing each core to handle two tasks at once.
Clock Speed
The frequency at which a processor executes instructions, measured in GHz (billions of cycles per second). Higher clock speeds generally mean faster single-threaded performance.
TDP (Thermal Design Power)
The maximum amount of heat a CPU or GPU generates under load, measured in watts. Determines cooling requirements and power supply sizing.
Overclocking
Running a CPU, GPU, or RAM at speeds higher than the manufacturer's rated specifications to extract more performance. Increases heat output and power consumption.
DDR5 (Double Data Rate 5)
The latest generation of system memory offering higher bandwidth and capacity than DDR4. Standard for new PC builds in 2026 with typical speeds of 5600-6400 MT/s.
