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

See also: K7 Microarchitecture

AMD announced their first multiprocessing-capable platform at Computex Taipei on June 5th, 2001. As with all the other Athlon families, the Athlon MP is also based on the K7 microarchitecture. 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).

Modding Athlon XP

In early 2002 HardwareZone.com published an article detailing the ability to modify a stock Athlon XP processor (which shares an identical core to the Athlon MPs) to allow it to recognize dual-socket configuration effectively turning it into an expensive Athlon MP processor. The modification is a trivial bridge on the L5 circuit on the top of the Athlon XP package (see article for detail). Various degrees of success has been reported.

Models

Palomino Core

Palomino-based microprocessors (i.e. Model 6) 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 (note that 'B' models operated at a lower FSB of 100 MHz). 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 models that were released around the same time.

Thoroughbred Core

AMD introduced Thoroughbred-based processors (i.e. Model 8) in late 2002. Those chips were manufactured on a newer 130 nm process which allowed them to be clocked at higher frequencies. The new process also allowed AMD to rearrange their design which allowed them to shave off roughly 300,000 transistors. These processors support MMX, SSE, Enhanced 3DNow!, and SmartMP Technology.

Barton Core

The last chip in the Athlon MP series was introduced in early 2003. The Barton-based processor (i.e. model 10), which was also manufactured on a 130 nm process, doubled the amount of level 2 cache (to 512 KiB). Barton-based processors sold for significantly lower price than the newer Opteron models which made them attractive for entry-level servers and workstations. These processors support MMX, SSE, Enhanced 3DNow!, and SmartMP Technology.
