Architecture: 2+2 INT + 2 FPU, SMT (2 thread)

Comment:
1. 繼K7之後, 終於有全新的architecture

2. 將core拆開做SMT, 好處係降低latency同埋scheduler易設計d
3. 在HTC / Server application, 2個INT同3個INT無乜分別, 所以效能會提升接近1倍, 拉近甚至超越Westmere / Sandy Bridge
4. 在single-thread application, 個3個INT減做2個, 如果INT同FPU無乜大改善, IPC比K10可能仲慢左少少
5. FPU由3個減到2個, 唔知AMD做乜

Architecture: 2 INT + 2 (?) FPU

Comment:
1. 如果係out-of-order execution既話, atom食硬塵
2. AMD用到來打dual-core i3 derivatives, 有d大想頭

3. 唔用SOI係正確的決定, 降低成本
