1. 究竟4-thread Bulldozer係有4個integer core (2 modules) 定4個floating core (4 modules)? 如果計多d core, marketing會好d, 但係就會licensing貴d同埋又玩"more is better"

2. 1個module (1/2 core?) 比傳統的1-core會多50% transistor, 之前又話5%既

3. 如果1個module真係計2-core, 而比K10仲有10-35% integer performance增加, 咁呢個2-issue integer unit真係勁過K10的3-issue integer unit wor, 但係有無可能呢?

多5%係Intel既Hyper-threading.

當然, hyper-threading遠比twin-integer core inefficient

但論用電,就有可能倒反轉.

主要問題反而係die size

耗電好多時係製程問題
