Intel Dual Core Processing power vs old Pentium 4?

Question

After unsuccessfully trying to upgrade the video card & power Supply in my Sony Vaio (PCVRS420) due to proprietary sized Power supply, I am fed up and considering a new PC. My Sony has been good otherwise for everything else I do. Pentium 4 at 2.8ghz (HTT) I saw a reasonable custom built with a dual core but only 1.8ghz. Will this be better than my 2.8Ghz. since it is new processor technology or will I see a real lag in my processing speed?? Any advice on a good custom place to buy would be appreciated as well! Thanks!!

Answer 1

It's because the newer Intel processors are more efficient, which means they can do more at less clock speed. In the end, the Intel Dual Cores will run faster than equivalent Pentium 4s.

Look at this table (Look at the red colored bars) :

http://www23.tomshardware.com/cpu_2007.html?modelx=33&model1=884&model2=907&chart=435

This shows that the Pentium Dual Core, although only running at 1600Mhz can do the task on 2 minutes and 9 seconds, while the fastest Pentium 4, which runs at 3800Mhz needs 3 minutes and 37 seconds to do the same tasks.

For buying I would actually recommend looking at your own city, it's because it will make choosing options easier as well as claiming warranty easier as well. You can buy online, but warranty processing will be slow since you need to mail the problematic hardware, mail will also delay the delivery of the fixed hardware as well.

Answer 2

The dual core will be "faster" in most cases because it shares the processing requirements between two chips instead of one.

It does not double the processing power... e.g. 1.8 + 1.8 = 3.6 MHz..... that is just NOT the case.

I wouldn't go for any core2duo or dual core that is less than 2.1 GHz, and would opt for 2.4 or better if you can afford it.

Also, get at least 2G RAM.

Hope this helps.

Answer 3

Yes dual core always better than the single P4. One core is 1.8 but two will be 2 times that which is 3.6. Not only that the dual core runs much much cooler, mine runs between 0 and 30 deg C on stock cooling so lots of overclock potential.

Answer 4

relies upon on what you do on your pc. in case you basically use it to browse the internet, mail, msn, acquire, gaming, and lightweight multi activity, then the twin middle is the greater applicable selection because of the better clock velocity, and maximum application application are helping twin middle now. in case you do various in intensity activity like video modifying, video encoding, 3-D animation, burning dvd, enjoying video games on an analogous time then the quad middle may well be a greater applicable ideal. in spite of the undeniable fact that there are actually not that many courses accessible that totally helps quad middle yet. Which subsequently why a bigger clock velocity twin middle continues to be the greater applicable selection on the 2nd. It runs cooler, makes use of much less capability and could be swifter for in ninety% of video games, and maximum application aside from video modifying. super bang dollars cpus for quad middle may well be the Q6600 2.4ghz, and the e8400 3.0ghz twin middle. the two are middle 2 Duo and are made by way of Intel. on the 2nd AMD's processors are slower while in comparison with intel. the two of them is efficient adequate to do something you thru at it.
