Multi-core processors
Processors with multiple cores executing instructions in parallel. Multi-core enables true parallelism improving performance on multi-threaded workloads.
Formula
Theoretical max speedup = 1 / ((1 − P) + P/N) [Amdahl's Law]
Real World
Modern gaming consoles like the PS5 use an 8-core AMD Zen 2 processor so the game engine can run physics, AI, audio, and rendering on separate cores simultaneously without stuttering.
Exam Focus
Always reference Amdahl's Law when discussing limits of multi-core — marks are lost by claiming performance scales linearly with cores.
