Template:mpu Athlon MP 2800+' (OPN AMSN2800DUT4C) based on the last-generation Barton core was a 32-bit x86 multiprocessor developed by AMD and introduced in early 2003 for the server and workstation market. This MPU, which operated at 2.13 GHz with a FSB transfer rate of 266 MT/s (x16 multiplier), was manufactured on a newer 130 nm process.

[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.
