In 2000, AMD plans to introduce differentiated versions of the AMD Athlon™ processor based on three new processor cores. These three new cores are codenamed Thunderbird, Spitfire and Mustang.
Thunderbird is planned to be a high-performance version of the AMD Athlon processor with integrated, full-speed L2 cache. Both Slot and Socket A implementations are possible Thunderbird will be targeted at the performance workstation and desktop markets.
Spitfire is planned to be a value version of the AMD Athlon processor with integrated, full-speed L2 cache. Spitfire is planned for Socket A implementation only. Spitfire will be targeted at the value desktop market.
Mustang is planned to be an enhanced version of Thunderbird, featuring a reduced core size, lower power requirements and up to 2MB of full-speed, on-die L2 cache. Both Slot and Socket A implementations are possible. Multiple versions of the Mustang core are planned to be targeted at the high-performance server/workstation, value and high-performance desktop, and mobile markets.
