Volgens een artikel van PC Home Taiwan zal de Mustang gebruik maken van de 64-bit x86-64 core die AMD momenteel in ontwikkeling heeft voor de Sledgehammer / K8. Ace's Hardware heeft de belangrijkste punten uit dit artikel in een leesbare taal bijeen gezet:
They also indicate it will be equipped with up to 2 MB of L2 cache, and will be available for both Slot A and Socket A.There's more planned for Mustang, however, including an entry level version only shipping for Socket A and even a mobile version. There was also some other information worth noting:
Thunderbird will be a K75 core on a 0.18-micron and integrated L2 cache at full speed (this we already know). As expected, the K6-2+ will debut in February. VIA's DDR-266 Athlon chipset, the KX266 should appear in the third quarter of 2000.
