Template:mpu Z500 is an ultra-low power 32-bit x86 microprocessor introduced by Intel in early 2008 specifically for Mobile Internet Devices (MID). The Z500, which is based on the Bonnell microarchitecture (Silverthorne core), is manufactured on a 45 nm process. This processor operates at 800 MHz with a TDP of just 650 mW and an average power of 160 mW. The MPU features a legacy 400 MT/s front-side bus capable of communicating with the Poulsbo chipset in both low-power CMOS mode as well as normal GTL mode (which also works with other chipsets).

Model price includes the chipset.

[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.
