与史蒂芬·乔布斯一起学英语视频教程(高级)：6_Steve Jobs Making the Best Computers
Today, it's time to begin a third transition.
We wanna constantly be making the best computers for you and the rest of our users.
And so, it's time for a third transition and yes it's true.
We are gonna begin the transition from the PowerPc to Intel processors.
And we are gonna begin it for you now and for our customers next year.
Now, why are we gonna do this?
Right?
Didn't we just get through going from OS 9 to OS 10?
Isn't the business great right now?
Why do we want another transition?
Because we wanna be making the best computers for our customer looking forward.
Now, I stood up here two years ago in front of you and I promised you this.
And we haven't been able to deliver that to you yet.
I think a lot of you would like a G5 in your Powerbook and we haven't been able to deliver that to you yet.
But these aren't even the most important reasons.
The most important reasons are that as we look ahead, though we may have great products right now...
...and we've got some great PowerPC products still yet to come,...
...as we look ahead, we kind of envision some amazing products we want to build for you.
And we don't know how to build them with a future PowerPc road map.
And that's why we're gonna do this.
When we look at Intel, they've got great performance, yes.
But they've got something else that's very important to us.
Just as important as performance is power consumption.
And the way we look at it is performance per watt.
For one watt of power, how much performance do you get?
And when we look at the future road maps projected out mid 2006 and beyond,...
...what we see is the PowerPc gives us sort of 15 units of performance per watt.
But the Intel road map in the future gives us 70.
And so, this tells us what we have to do.
