  2. List of Mac models grouped by CPU type - Wikipedia

    en.wikipedia.org/wiki/List_of_Mac_models_grouped...

    The M4 Pro has 14 CPU cores (10 performance and 4 efficiency), while the M4 Max has 16 CPU cores (12 performance and 4 efficiency); both have a 16-core Neural Engine. The M4 Pro and M4 Max have a 20-core and 40-core GPU, and a 256-bit and 512-bit LPDDR5X memory bus supporting 273 and 546 GB/s bandwidth respectively.

  3. Mac Pro - Wikipedia

    en.wikipedia.org/wiki/Mac_Pro

    The Mac Pro Server includes an unlimited [8] Mac OS X Server license and an Intel Xeon 2.8 GHz quad-core processor, with 8 GB of DDR3 RAM. [114] In mid-2012, the Mac Pro Server was upgraded to an Intel Xeon 3.2 GHz quad-core processor. The Mac Pro Server was discontinued on October 22, 2013, with the introduction of the cylindrical Mac Pro.

  4. Load (computing) - Wikipedia

    en.wikipedia.org/wiki/Load_(computing)

    An idle computer has a load number of 0 (the idle process is not counted). Each process using or waiting for CPU (the ready queue or run queue) increments the load number by 1. Each process that terminates decrements it by 1. Most UNIX systems count only processes in the running (on CPU) or runnable (waiting for CPU) states.

  5. CPU-bound - Wikipedia

    en.wikipedia.org/wiki/CPU-bound

    The term can also refer to the condition a computer running such a workload is in, in which its processor utilization is high, perhaps at 100% usage for many seconds or minutes, and interrupts generated by peripherals may be processed slowly or be indefinitely delayed.

  6. Energy proportional computing - Wikipedia

    en.wikipedia.org/wiki/Energy_proportional_computing

    In computing, energy proportionality is a measure of the relationship between power consumed in a computer system, and the rate at which useful work is done (its utilization, which is one measure of performance). If the overall power consumption is proportional to the computer's utilization, then the machine is said to be energy proportional. [1]

  7. Apple M2 - Wikipedia

    en.wikipedia.org/wiki/Apple_M2

    Apple M2 is a series of ARM-based system on a chip (SoC) designed by Apple Inc., launched 2022 to 2023. It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks , the iPad Pro and iPad Air tablets , and the Vision Pro mixed reality headset.

  8. CPU time - Wikipedia

    en.wikipedia.org/wiki/CPU_time

    CPU time (or process time) is the amount of time that a central processing unit (CPU) was used for processing instructions of a computer program or operating system. CPU time is measured in clock ticks or seconds. Sometimes it is useful to convert CPU time into a percentage of the CPU capacity, giving the CPU usage.

  9. Computer multitasking - Wikipedia

    en.wikipedia.org/wiki/Computer_multitasking

    This optimizes CPU utilization by keeping it engaged with the execution of tasks, particularly useful when one program is waiting for I/O operations to complete. The Bull Gamma 60 , initially designed in 1957 and first released in 1960, was the first computer designed with multiprogramming in mind.
