Template:mpu The Athlon MP 1800+ (OPN AMP1800DMS3C) based on the Palomino core was a 32-bit x86 multiprocessor developed by AMD and introduced in late 2001 for the server and workstation market. This MPU operated at 1.53 GHz with a FSB transfer rate of 266 MT/s (x11.5 multiplier). This processor, which was based on the K7 microarchitecture, was manufactured on a mature 180 nm copper interconnect technology at AMD's Fab 30 in Dresden, Germany.

[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.
