Because a CPU's TDP is affected by its number of cores and speed, a CPU that runs faster or has more cores will consume more power and generate more heat and, therefore, will have a higher TDP. Each CPU has a maximum TDP designation, and, in essence, the more power a CPU consumes, the more heat it will produce. TDP is a term that refers to the maximum amount of power a CPU can use. The faster the clock rate of a CPU, the more work the CPU can complete in a given amount of time.įinally, Thermal Design Power (TDP) needs to be discussed. For example, a CPU that runs at 2.3GHz completes 2.3 billion calculations every second. A CPU socket.Ī CPU runs at a given clock rate or frequency, rated in gigahertz (GHz), which then controls how fast the calculations on a CPU are executed. Most modern home systems and laptops have two to four cores, while workstations and servers have between eight and 28. By having multiple cores in a CPU, each core can work on a different task in other words, the more cores a CPU contains, the more work the CPU can complete. In the early days of computing, a CPU had a single core to execute these instructions, but as technology got better, CPU manufacturers were able to fit multiple cores onto a single CPU chip, which is then placed on a socket on a computer's motherboard ( Figure 1). A CPU is the part of a computer that takes instructions from a computer program and performs basic arithmetic, logic, controlling and input/output (I/O) operations as specified.
