Athlon MP (Athlon Multiprocessor) was a family of 32-bit x86 server multiprocessors designed by AMD specifically for the server and workstations market. Athlon MP was AMD's first multiprocessing-capable platform.

Overview

AMD announced their first multiprocessing-capable platform at Computex Taipei on June 5th, 2001. The platform includes the Athlon MP processors as well as the AMD-760MP northbridge chipset. AMD-760MP supports one- and two-way setups and Double Data Rate (DDR) memory operating at 133 MHz. At the time, AMD's vice president for their servers group stated Athlon MP processor delivers up to 38% higher performance over their competition (presumably referring to Xeon).

Models

Palomino Core

Palomino-based microprocessors were manufactured on AMD's mature 180 nm process copper interconnect technology at Fab 30 foundry in Dresden, Germany. The core implements an exclusive 256 KiB L2$ and a 128 KiB L1$. As with all Socket A processors (EV6 system bus), Athlon MP operate on a 133 MHz FSB DDR (double data rate) yielding an effective 266 MT/s transfer rate. These processors support MMX, SSE, Enhanced 3DNow!, and SmartMP Technology. AMD came short with Palomino by not supporting SSE2 which came out in the various Pentium 4 that were released by Intel around the same time.
