  2. Dynamic frequency scaling - Wikipedia

    en.wikipedia.org/wiki/Dynamic_frequency_scaling

    The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.

  3. Amiga Chip RAM - Wikipedia

    en.wikipedia.org/wiki/Amiga_Chip_RAM

    However, certain chipset DMA, such as high-resolution graphics with a larger color palette, Copper, or blitter operations, can use any spare cycles, effectively blocking cycles from the CPU. In such situations CPU cycles are only blocked while accessing shared RAM, but never when accessing Fast (CPU-only) RAM (when present) or ROM. [2]

  4. Underclocking - Wikipedia

    en.wikipedia.org/wiki/Underclocking

    Underclocking can also be performed on graphics card processor's GPUs, usually with the aim of reducing heat output. For instance, it is possible to set a GPU to run at lower clock rates when performing everyday tasks (e.g. internet browsing and word processing), thus allowing the card to operate at lower temperature and thus lower, quieter fan speeds.

  5. Direct memory access - Wikipedia

    en.wikipedia.org/wiki/Direct_memory_access

    Imagine a CPU equipped with a cache and an external memory that can be accessed directly by devices using DMA. When the CPU accesses location X in the memory, the current value will be stored in the cache. Subsequent operations on X will update the cached copy of X, but not the external memory version of X, assuming a write-back cache. If the ...

  6. Clock rate - Wikipedia

    en.wikipedia.org/wiki/Clock_rate

    For example, an IBM PC with an Intel 80486 CPU running at 50 MHz will be about twice as fast (internally only) as one with the same CPU and memory running at 25 MHz, while the same will not be true for MIPS R4000 running at the same clock rate as the two are different processors that implement different architectures and microarchitectures ...
