砍這麼多, 真的沒問題嗎?

原值: stated 2 billion transistors. (20億個)
砍到剩: 1.2 billion transistors (12億個)
可是晶片面積不變...? 315mm^2
"The reduction occurred despite the fact that the die size remains unchanged at 315 square millimeters"

company representatives stated they were "simply correcting a mistake regarding the chip's actual specifications"

總不會原來只是 "打字錯誤" 吧?
