Core DUO and Pentium D

Hello.

Can anyone point me to articles/white papers or outline the differences
between these two CPU-families?

I can see that the Core-series are newer and more expensive than the D,
but the frequency is lower.

What may be the advantage with Core-DUO? E.g. in graphics context.


Regards,

Ronny Mandal

The Core 2 Duo's are faster,cooler running,and more energy efficient than
the Pentium D's,by a wide margin.They're the fastest cpu's out there.

Thanks, but:

How can the Core 2 operate with a lower frequecy and make calculations
faster than the Pentium D?

The architecture is different, it is based on Plll and Pentium M. You
should Google for a complete description.

Yes,the Core 2 design doesn't rely on frequency for speed,just as AMD's
CPU's don't.Intel followed their example to catch up and pass them in the
market.

I don't know the technical detail, but here's what I can tell you. My 2.13
GHz Core 2 Duo system simply kills my 2.8 GHz P4 system. My understanding is
that current software doesn't fully utilize the dual core, and yet the C2D
is blazingly fast. It's not just when I play games. I can definitely feel
the speed when doing casual stuff on my PC. I planned to overclock it (the
C2D is highly overclockable) but saw no point doing so because it's just so
fast.

Because it does more work per clock cycle. The relevant technical
measurement is "instructions per cycle."

Every processor has both a theoretical maximum number of instructions per
cycle (higher on Core 2, although on paper the P4/Netburst wasn't that bad)
and then an average number of instructions per cycle (much higher on Core 2,
as the a lot of technical decisions which went into the P4 meant that it
didn't live up to even its on-paper performance.)

It's the same reason why AMD has been able to often significantly outperform
older Intel designs with higher clock speeds.
