Maybe this will explain it better >
Pick the least inaccurate statement
(A) Now with a 15% higher speed @ the exact same speed
(B) Now with a 15% better efficiency level @ the same level of efficiency
(C) Now with a 15% lower operating temperature @ the exact same temperature
(D) None of the above
If you still can't figure it out, the correct answer is (D)
Regardless of what you heard, words "STILL" have standard meanings
All your options there are contradictory and make zero sense.
I assumed better if you, and that your
ambiguous sentence meant you didn't understand why percentage increases in speed and efficiency are not the same. My comment was a response to that.
But no; you really did mean it in a nonsensical way.
'According to TSMC, its 3nm tech can offer up to a 15 percent speed improvement and up to 30 percent power reduction at the same speed compared to its N5 technology.'
TSMC made no mention of the efficiency at the improved speeds, only at the same speed as N5.
Shawn did mess it up a bit though, as the original text is:
'up to 15% speed improvement at the same power and up to 30% power reduction at the same speed as compared with N5 technology.'
Either way, you can either get 15% more speed, 30% power reduction, or anything in-between, but not both say the same time.
