Intel Atom - Performance

Performance

The performance of a single core Atom is about half that of a Pentium M of the same clock rate. For example, the Atom N270 (1.60 GHz) found in many netbooks such as the Eee PC can deliver around 3300 MIPS and 2.1 GFLOPS in standard benchmarks, compared to 7400 MIPS and 3.9 GFLOPS for the similarly clocked (1.73 GHz) Pentium M 740.

The Pineview platform has proven to be only slightly faster than the previous Diamondville platform. This is because the Pineview platform uses the same Bonnell execution core as Diamondville and is connected to the memory controller via the FSB, hence memory latency and performance in CPU-intensive applications are minimally improved.

Famous quotes containing the word performance:

    So long as the source of our identity is external—vested in how others judge our performance at work, or how others judge our children’s performance, or how much money we make—we will find ourselves hopelessly flawed, forever short of the ideal.
    Melinda M. Marshall (20th century)

    Having an identity at work separate from an identity at home means that the work role can help absorb some of the emotional shock of domestic distress. Even a mediocre performance at the office can help a person repair self-esteem damaged in domestic battles.
    Faye J. Crosby (20th century)
