AMD's Mustang processor was supposed to have support for up to 4MB of L2 cache on the chip die with tweaks to the Athlon Thunderbird core to allow for the addition of more L2 cache on chip, possibly with more pipeline stages, enabling higher clock speeds.
The core was updated, but without the additional pipeline stages and L2 cache. The "Mustang" core, now called Palomino in most references is used in reworked Athlon and Duron chips which support improved memory operations and Intel's SSE (SSE-1, not SSE-2) instructions. The extra cache will have to wait for the Hammer series of chips. This original Mustang chip has now become the Athlon MP which arrived at 1.0 and 1.2 GHz speeds and works in dual-processor configurations.
