sexyny Posted November 10, 2006 Share Posted November 10, 2006 I've been away from the PC market and was just wondering which is better between the two? is the dual core a replacement for the P4? Link to comment Share on other sites More sharing options...
neeeeeeeeeek Posted November 10, 2006 Share Posted November 10, 2006 Pretty much. Newer architecture so runs much cooler with similar performance at much lower clock speeds. My new laptop is code 2 due 5600 and it flys along with barely a whisper, my old one was a 3Gz P4 and it ran bloody hot with some serious fan action all the time.

richard Posted November 10, 2006 Share Posted November 10, 2006 According to Tom's hardware guide:- http://tomshardware.co.uk/cpu/charts.html Core 2 Duo - generally. There are several models of each and you can use the link above to pick out specifics. Core 2 is like having two processors running at once. But they have to have separate jobs to do, as they are kind of independent. That's why Tom's hardware has a whole bunch of stats to cover such irregularities.

sallonoroff Posted November 10, 2006 Share Posted November 10, 2006 No comparison... a Core2Duo would destroy a Pentium4 in any test you'd care to run. Except maybe a 'highest temperature possible' competition... . Link to comment Share on other sites More sharing options...
richard Posted November 10, 2006 Share Posted November 10, 2006 I'd tried the lowest spec duo against the highest spec pentium 4 and on some benchmarks it did come lower, probably because the benchmark could only make use of one of the "cores". Which is actually a likely state of affairs. You need to write threaded programs to fully utilise both the cores, which is a relatively new thing to do for many types of applications. Of course web servers and databases have been doing threading for different reasons for years. Link to comment Share on other sites More sharing options...
Guest Posted November 10, 2006 Share Posted November 10, 2006 Believe me, if you use your PC for lots of desktop work you'll notice the difference with a dual-core CPU....no longer do I have to run video encoding overnight when I'm not using the PC, and just in general usage it's faster IMO Link to comment Share on other sites More sharing options...
marmite Posted November 10, 2006 Share Posted November 10, 2006 Is Core duo what the Macs are currently running on? Link to comment Share on other sites More sharing options...
Guest Posted November 11, 2006 Share Posted November 11, 2006 Yep. The Macs are now being switched to Core 2 Duo as well. Link to comment Share on other sites More sharing options...
Bago Posted November 11, 2006 Share Posted November 11, 2006 Snap. I was asking myself this Q a little while back too. From my vague memory... 386, 486, Pentium I Pentium II Pentium III Pentium 4 (?) (The following are still available on the market.) ---------------- Pentium Celeron Pentium M - Intel Mobile Technology Pentium Core Duo - 1st generation for Core Duo technology. Pentium Core 2 Duo - 2nd gen. Am a little bit hazy around the Pentium 4 period. I'm not sure if Core 2 Duo is now on the market, but I think they're slowly coming out. You need to check out the CPU model number to see if it is a proper 2nd generation chip. I got an AMD laptop which had the dual core facility, which I think just came out before the Core 2 Duo. This was in the last month or so. Oh, Celeron and Pentium M is the entry level now, I think. Link to comment Share on other sites More sharing options...
defstef Posted November 12, 2006 Share Posted November 12, 2006 I'm not sure if Core 2 Duo is now on the market, but I think they're slowly coming out. As probedb pointed out, new iMacs, Macbook Pros and now Macbooks sport Core 2 Duos. The mini is the only Mac that still houses a first generation Duo.
