Every CPU Core and Thread Explained in Detail What’s a CPU core? What’s a thread? Do more cores always mean faster? In this video I break down cores vs threads, SMT/Hyper-Threading, parallel processing, clock speed vs core count, IPC, and real-world advice on how many cores you actually need for gaming, editing, 3D, coding, or everyday use. We also cover why software scaling matters, scheduler queues, and why 6–8 cores can beat 16+ cores in many apps. Clear, practical, no fluff.
