For example, building the CPU out of better, faster transistors. However, sometimes pushing one type of performance to an extreme leads to a CPU with worse overall performance, because other important aspects were sacrificed to get one impressive-looking number, for example, the chip's clock rate (see the megahertz myth).
However, the idle process does not use up computer resources (even when stated to be running at a high percent). Its CPU time "usage" is a measure of how much CPU time is not being used by other threads. In Windows 2000 and later the threads in the System Idle Process are also used to implement CPU power saving.
When your AOL Desktop Gold is ready for an update, we'll push it through to you automatically. All you'll need to do is close and reopen your AOL Desktop Gold every couple of days to ensure you're using the most updated version. Once you reopen AOL Desktop Gold you'll be using the newest version available to you.
Amdahl's law does represent the law of diminishing returns if one is considering what sort of return one gets by adding more processors to a machine, if one is running a fixed-size computation that will use all available processors to their capacity. Each new processor added to the system will add less usable power than the previous one.
TOP500 ranks the world's 500 fastest high-performance computers, as measured by the High Performance LINPACK (HPL) benchmark. Not all existing computers are ranked, either because they are ineligible (e.g., they cannot run the HPL benchmark) or because their owners have not submitted an HPL score (e.g., because they do not wish the size of their system to become public information, for defense ...
The useful work that can be done with any computer depends on many factors besides the processor speed. These factors include the instruction set architecture, the processor's microarchitecture, and the computer system organization (such as the design of the disk storage system and the capabilities and performance of other attached devices), the efficiency of the operating system, and the high ...
Using RAM that was running twice as fast as the CPU clock allowed a second system to interleave its accesses between the CPUs by timing themselves on every other clock cycle. This was widely used for updating the display using main memory as a framebuffer. Common RAM of the late 1970s ran at 2 MHz, so most machines had a CPU running around 1 MHz.
An IBM RISC based architecture was used for the PowerPC CPU which was released in 1992. In 1994, Apple Computer introduced Macintosh computers using these PowerPC CPUs. Initially, this architecture met hopes for performance, and different ranges of PowerPC CPUs were developed, often delivering different performances at the same clock rate.
