  2. iCOMP (index) - Wikipedia

    en.wikipedia.org/wiki/ICOMP_(Index)

    iCOMP for Intel Comparative Microprocessor Performance was an index published by Intel used to measure the relative performance of its microprocessors.. Intel was motivated to create the iCOMP rating by research which showed that many computer buyers assumed that the clock speed – the “MHz” rating – was indicative of performance, regardless of the processor type. iCOMP ratings based on ...

    en.wikipedia.org/wiki/Performance_Rating

    AMD initially branded its AMD K6 processors with a "PR2" rating but dropped this after consumer confusion. [4] AMD revived the branding for its Athlon XP , which was released in 2001. The efficient Athlon XP chips could perform better than similarly-clocked chips from Intel's competing Pentium 4 line-up, which depended on high clock speeds to ...

    en.wikipedia.org/wiki/Random-access_memory

    A portion of the computer's hard drive is set aside for a paging file or a scratch partition, and the combination of physical RAM and the paging file form the system's total memory. (For example, if a computer has 2 GB (1024 3 B) of RAM and a 1 GB page file

    Modules are instead designed to run at different clock frequencies: for example, a PC-1600 module is designed to run at 100 MHz, and a PC-2100 is designed to run at 133 MHz. A module's clock speed designates the data rate at which it is guaranteed to perform, hence it is guaranteed to run at lower ( underclocking ) and can possibly run at ...

  7. Memory hierarchy - Wikipedia

    en.wikipedia.org/wiki/Memory_hierarchy

    The number of levels in the memory hierarchy and the performance at each level has increased over time. The type of memory or storage components also change historically. [6] For example, the memory hierarchy of an Intel Haswell Mobile [7] processor circa 2013 is: Processor registers – the fastest possible access (usually 1 CPU cycle). A few ...
