Sorry thought discussing 4ghz single core (older chip) versus 2ghz single core (newer chip)

Goodness grief @ the amount of gibberish in this thread....

ok he is now stating this;

a hav the D is better, they hav the same arcitecture (64bit) the only difference is that the D has 2 caches leading up to 2MB and the core 2 has 1 that 2MB. see they are the same. only difference is that the D has a 3.2 GHz processing clock while the core 2 has a 2.7 GHz processing clock

Isnt a core2duo 2.7ghz maybe but since theres 2 cores really (5.4ghz)

So incredibly wrong that it's almost laughable. The benchmarks alone speak for themselves - a Core 2 Duo can beat a much higher clocked Pentium D by a large margin so how can you say they're the same architecture? Yes they're both 64-bit, but an Athlon 64 is also 64-bit yet they're still very different. By that logic, a Pentium II and a Pentium 4 Northwood are the same architecture because they're both 32-bit - of course that is not how it works because they aren't the same at all.

As mentioned before, you need to do some reading. Start off with this:

http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=2795

This simple statement sums it up:

"In many cases, the $183 Core 2 Duo E6300 actually outperformed Intel's previous champ: the Pentium Extreme Edition 965. In one day, Intel has made its entire Pentium D lineup of processors obsolete. Intel's Core 2 processors offer the sort of next-generation micro-architecture performance leap that we honestly haven't seen from Intel since the introduction of the P6.".

Yes, the 1.83GHz Core 2 Duo is better than the 3.73GHz Pentium D in most cases. So in short, such ridiculous claims (the C2D and P-D being the same architecture) simply should not be made without some research being put in beforehand.

Also, two cores running at, say, 2.66GHz does NOT equal one CPU running at 5.33GHz. It does not work that way. It is simply two processors running at 2.66GHz and therefore they are both capable of executing threads at the same time.

The Core 2 owes its roots to the powerful P6 core which clock for clock was more efficient than a Netburst cpu which was a new design from ground up that did not end on a good note though it had its moments in glory. Simply put, Core 2 architecture is very very superior to any Pentium 4/Netburst design.

As described in title, my friend thinks a Pentium D is better than a core2duo, Can someone put him right?

Lol edited

Tell him he is right. Then he can't argue and you can laugh at him and get your revenge when he goes out and buys one.

Out of interest, do you know how the Core 2 stacks up against the Athlon 64 and Athlon XP clock for clock?

Higher performance.

Yep, in order of worst to best -

Athlon XP - fought against the early PIV and won a lot but started to lose ground with later models.

Pentium 4/ Netburst - Good for its day and did shine at times but in the end lost out, imho due to thermal and power demands getting outrageous and curbing the one thing that made it shine - clockspeed.

Athlon 64 - Great design and owned Netburst for a long time and was definetly king of the hill for a few years, decent clockspeed, IMC and great IPC made a winner out of this. If Intel was still using the Netburst architecture it would still be king for a long while imo since clockspeeds are getting reasonably high.

Core 2 - From its early days as the Banias/Dothan/Core Duo there was something special there and when Core 2 Duo was unleashed it made a fairly big leap in Architecture and clock for clock the best modern cpu, owns everything currently and if some people are to be taken seriously it rules the world as well and is the best thing since sliced bread
