which is the better processor pentium 4 3.06GHz or pantium D 2.66GHz? whats new in pentium D then pentium 4?

Answer 1

Well conrad is absolutely right you can't just add the 2.66 together. Now to definitively answer your question the Pentium D is better, period. Here is a link to a site that benchmarks processors, which should prove my point. http://www23.tomshardware.com/cpu.html
Don't always just look at the speed, for example a 2.4Ghz of the new Core 2 Duo will easily crush either of these two.

Answer 2

Really, this is sad. The answers thus far are only half right. Half right in the fact that the Pentium D is a new architecture and is faster than the Pentium 4. Completely wrong in the fact that to this point many have been labeling the Pentium D you listed as having an effective speed of 5GHz+, this is completely wrong. You can't simply add clock speeds from two different cores to get a total clock speed, it's... just... WRONG. You have two cores operating at a speed of 2.66GHz (note not all Pentium D models are dual core but it sounds like the one you are looking at is simply based on clock speed but look at the model number 805, 840, etc. and you'll be able to find out if it is dual core or not). That being said, there aren't many multithreaded applications out there except for Windows. And Windows will divide processes among the cores so your background processes will run on one and whatever application requires the most power will run on the other core all on its own. This is a simple example and I could go into more detail but that's just to give you an idea. All these people who have been adding together clock speeds are just wrong... I don't know how else to put it.

Answer 3

The Pentium D 2.66Ghz will ultimately be much faster than a regular Pentium 4 3.06Ghz. Firstly, the Pentium D has a new chip architecture that has vast improvements in processing over the Pentium 4, which is quite old. Second and more noteworthy, the Pentium D is a dual core chip. This means that there are, in simple terms, two chips in one. So (for extremely simple calculation), the total speed for the Pentium D 2.66Ghz is about 5Ghz.

Answer 4

Pentium 4 3.06 is the faster CPU and Pentium 4 is a fine processor. The difference in Pentium D may be only in a name.

Answer 5

Pentium D, it helps twin processor cores on a single CPU die, meaning it incredibly is speedy and good for multi-tasking. A twin middle processor is greater effectual at working distinctive applications. Like applications that take one hundred% of your cpu and your gadget will become unresponsive on a single middle gadget, twin middle continues to be responsive by way of fact of the different middle.

Answer 6

Pentium D is considered a dual core, meaning that there are two processors on one physical chip. Compared to the Pentium 4 it has only one physical core on the chip. In theory the Pentium D would be around 5.32Ghz combined. Check out Intel's website

Answer 7

The Pentium D allows dual threading of processes because it has 2 CPU cores, hence it can provide an effective 5.5Ghz. This might not seem much now, but the basis for quad and 8way core processors has now been created, giving a potential for 20Ghz!. Not to mention the increased CPU speeds (a 3Ghz CPU would be 12Ghz in a quad).

Now you wont in practice see 4x increase, but the CPU creators have reached a plateau on CPU core speeds, so parallel processing seems to be the way forward.
