ALU doing Warp*2
The good ole backbone to any good CPU is a good calculator. Making a
fast ALU that runs at the speed of the chip is easy to do to get a good office
benchmark score, where the ALU comes in handy. But, to get even better performance,
every overclocker knows that cranking up the clock speed is the way to do
things. Intel has taken a page from the book of mighty logic, and doubled
the speed of it’s calculator. So, in effect, if you’ve got a Pentium 4
running at 1.5GHz, the ALU, or Integer Unit (INT), will be doing 3GHz.
This will make M$ Office run like never before (The same 256KB of Advanced
Transfer Cache from the Pentium !!! doesn’t hurt either). The doubling of
the speed of this chip is done very easily by a special electrical gate that
will simply output double the clock speed that is inputted into it. This
is contrary to preliminary beliefs that said the ALU would be using DDR
technology, which transfers data on the rising and falling edge of the clock
cycle. Very simple, very easy, again innovative.
Conclusion
We all know that with time must come progress. It can’t be said right
now whether or not the Pentium 4 will actually have a lower price/performance
ratio than the Pentium !!!, but what can be said is unless there are some more
features on the Pentium 4, it will more than likely perform worse per clock than
the P!!!. But as said before, that lower performance comes with a sliver
lining. It will allow the P4 to reach higher clock speeds that the P!!!
couldn’t have reached, thus increasing the performance in the long run.
But, no matter what you do, Don’t buy a P4 when they come out. Wait until
you hear how they perform from others, and wait until the prices drop, because a
1.5GHz version of the P4 is expected to be $800 when the P4 is debuted in Q2
