Why are all the new computers only coming with dual core processors and slower speeds than before?

Question

Also, which is better:

* 3.0 GHz Processor
----OR------
* 2.4 GHz Dual Core Processor

Answer 1

2.4GHZ dual core. Two processors handle twice the information, so your processing almost twice as fast.

Answer 2

The 3.0 Ghz with hyperthreading is superior.

Also, you can get an Athlon processor, no reason to stick with intel.

A dual core processor is between a single core processor and a dual processor system for architecture. A dual core processor has two cores but will share some of the other hardware like the memory controller and bus. A dual processor system has completely separate hardware and shares nothing with the other processor.

A dual core processor won't be twice as fast as a single core processor nor will it be as fast as a dual processor system.

It will fall somewhere in the middle but there are going to be specific advantages.

FOR THOSE OF YOU WHO THINK that a 2.4 Ghz dual core is actually putting out 4.8 GHz, you are sadly mistaken.

You also want to look at the L1 cache and front side bus speeds.

Answer 3

Whoever gave Michael a negative obviously not informed about this, 2.4 Dual is more advantageous to have but twin CPU obviously need better software finesse.

3.0 GHz single can be thought as a one-lane highway, 2.4 GHz is a two-lane local road, performance is thought as which way has better flowing traffic.

Answer 4

You should check to see what socket your motherboard uses :] The Dual Cores now use the LGA 775 specification while later Pentium's use the 478 socket I think. There were some 775 socket Pentium 4's I think though.

Answer 5

2.4 dual core is much better (2.4+2.4=4.8GHz)

think of it this way:

the first processor has 1 tunnel, because it is a single core processor, so lets imagin lots of little cars going through this tunnel at 3km a second, now we have a dual core cpu with 2 tunnels, and the same cars going throu it but at a speed of 2.4 km a second, but because there are two tunnels more cars are able to go through. This makes the dual core cpu much better then a single core.

Hope this helps

if you got the money go for quad cores

Answer 6

Technically, the Dual Core is twice as fast as it says. so a 2.4GHz Dual core would be equal to a 4.8GHz regular processor. so obviously the 2.4GHz Dual core is a lot faster than the 3.0GHz Pentium 4. (dual cores alow you to run more programs faster, so video editing or gaming is the best thing to use dual cores for. (they are great for regular comptuer too) I would look on eBay for your computer tho, I bet you could get a dual core computer with the same specs you are looking for in a brand new one for half the price. (just watch the shipping charges)


Good Luck!

Answer 7

The 'speed' you're referring to isn't the only indicator of a computer's speed. It used to be the most important, but it no longer is.

The Dual-Core 2.4GHz will blow away the 3.0GHz Single-Core CPU. In essence, having 'two' CPUs running at 2.4GHz will get more done than one CPU running at 3.0GHz.

Other indicators of a CPUs speed are cache, FSB, and the number of cores.

Answer 8

dual core is 2 processors in one
meaning total speed 3ghz x 2 = 6ghz
or 2.4 x 4.8ghz

Answer 9

If you are talking about Intel Core2 Duo, the reason is the following:

Core 2 Duo has 64-bit architecture but Pentium has 32-bit architecture.

Shortly: Core 2 Duo can count further (it recognize and use binary numbers up to 64-bit) than Pentium.

If you browse for Apple computers, you'll see they also has lower clock (due to the 64-bit architecture), but they more powerful than 32-bit Pentium

Answer 10

depends for what you need
in some cases 3.0 is better and much faster (mostly for older applications)
2.4C2D is better for newer applications

*newer applications are mostly designed for C2D proc's

it is better to buy (if you want) 2.4C2D because he is future
(it is new so it will need time to programmers reconstruct their programs for C2D proc's)

PS. that isn't true: 2.4 + 2.4 = 4.8 - there are 2 cores which work in 2.4GHz, example: 2.4GHz C2D proc isn't faster twice then 2.4GHz proc, it is faster but not so much (approx 60%-70% is faster)
