Template:mpu Atom N270 is an ultra-low power 32-bit x86 single-core microprocessor introduced by Intel in mid-2008. The N270 is specifically designed for nettops and various other mobile internet connected devices. This processor, which was fabricated on Intel's 45 nm process, was based on the Bonnell microarchitecture. The Atom N270 operates at 1.6 GHz with a TDP of 2.5 W with an average power consumption of 600 mW. The MPU features a legacy 533 MT/s QDR front-side bus.

[Edit/Modify Cache Info]

Cache Organization Cache is a hardware component containing a relatively small and extremely fast memory designed to speed up the performance of a CPU by preparing ahead of time the data it needs to read from a relatively slower medium such as main memory. The organization and amount of cache can have a large impact on the performance, power consumption, die size, and consequently cost of the IC. Cache is specified by its size, number of sets, associativity, block size, sub-block size, and fetch and write-back policies. Note: All units are in kibibytes and mebibytes.
