The control unit reads the instruction and derives the meaning, then directs the required data to be transferred from memory to the arithmetic/logic unit (ALU). These first two steps combined are referred to as the instruction time or I-time. The ALU carries out the arithmetic or logical in...
Multithreading is mostly used for tasks that can be easily divided into multiple threads and don’t include data dependencies meaning they don’t heavily depend on each other or include several hazards. Tasks that can be broken into several threads and be executed simultaneously usually include desk...
Some older game engines are known for their reliance on single-threaded performance, meaning they mostly use a single CPU core and get a major boost from higher clock speeds. Today, game engines like Unreal Engine 4 utilize multiple cores when creating complex scenes2. Engines may also use ...
Hyper-Threading is Intel’s term for simultaneous multithreading (SMT). This is a process where a CPU splits each of its physical cores into virtual cores, which are known as threads. For example, most of Intel's CPUs with two cores use hyper-threading to provide four threads, and Intel...
Some newer CPUs, like the Intel Xeon “Nehalem”, sport a technology called Hyper-Threading which allows two threads to run simultaneously on each core. macOS presents this as 2 virtual cores per actual core, meaning a 4 core CPU will appear as 8 cores. So it’s normal for some Macs to...
This is NOT to say HyperThreading is useless or detrimental for most. In most cases Windows threads are I/O bound, meaning they spend most of their time waiting for I/O and are not intensively using the CPU. In these cases, delegating them to a logical core is appropriate and can free...

Over the past year we've reported on Simultaneous Multi-Threading (SMT) technology on Intel CPUs. Although it originally started out as a potential meaning behind the codename Jackson Technology, Intel officially revealed their SMT technology at last fall's IDF. The codename Jackson was replaced ...
Over in #45, @CraftComputing ran into some errors running this playbook on an Intel Granite Rapids Xeon 6980P system. That system has 2x Intel Xeon 6980P 128-Core / 256-Thread CPUs, meaning there's a total of 256 cores, and 512 threads, ...
