Pentium4 3.0Ghz or PentiumD 820 2.8Ghz for multi-tasking?

Pentium4 3.0Ghz or PentiumD 820 2.8Ghz for multi-tasking (photoshop, internet, TMPGEnc)

[vico1]

Personally...I`m waiting for Conroe.

[jagabo]

If the choice is only between those two, and you don't care about power consumption, the choice is obvious, PentiumD 820.

But as vico1 said, I'd wait for Conroe (better performance and less power consumption). They will start appearing late this month. But they will probably be hard to get for a while.

For my multi-task uses (stated above) would it be better to go dualcore (no specific Pentium yet), or go the P4 with faster Ghz?

Multicore is better unless you frequently run a single-threaded application and don't use the computer for anything else at the same time. One example of that would be gaming.

TMPGEnc, in particular, is well multithreaded and runs much faster on dual core processors.

I have a couple of systems. One using a P4 3.2GHz overcloked to 3.6GHz and a Pentium D 920 overclocked to 3.0GHz.

I use the P D 920 for most rendering matters because it is faster in this area with the software I use.

The P4 3.2 @ 3.6 it is great for gamming. This machine has the best video card.

Both system are capable, but I use one over the other depending on what I want to do.

Whatever happed to Moores law? I got a regular computer 3 years ago & its 2.4ghz. A year later another one that is 2.8ghz. Should be around 16ghz by now.

Speed is not simply a matter of Hz.

[KBeee]

Moores Law has nothing to do with processor speed - it's to do with processor complexity
And those new Conroes are looking like pretty fine CPU's

hi,
This is my 2 cents worth .. smile....
your pentium 4 a standard single core..... and your pentium d is a dual core..

when it come to dual core.... can be very good and faster for mulittasking... HOWEVER your programs that you use must be designed to take advantage of dual core!!! otherwise that 2nd core is worthless!! ....!! that pentiume d will act like just a pentium 4 in most cases..

I f you don't have any programs that designed for dual core use... your better off getting a much faster pentium 4!! I am not even sure if winxp is setup for dual core!
note: i don't know if any of the photoshop versions are desigend to take advanta of dual core!

that my understanding and my opinion...

[jagabo]

I f you don't have any programs that designed for dual core use... your better off getting a much faster pentium 4!!

Many programs are multithreaded. In fact, I would say that most programs where you spend a lot of time waiting for the computer (like video encoding) are multithreaded. The major exception is games.

I am not even sure if winxp is setup for dual core!

It is.

note: i don't know if any of the photoshop versions are desigend to take advanta of dual core!

Many of the plugins for Photoshop have been multithreaded for a long time.

Certainly, in a multitasking scenario like encoding a video in the background with TMPGEnc and running Photoshop in the foreground, dual core will perform much better. And this would be true whether the programs were designed for multicore or not.

Hi,
I agree with you photoshop is designed for hyperthreading and for quite awhile.... but there a difference between hyperthreading technology and dual core technology... there not the same!! ....
Now when hyperthreading first cam out it was discribe "as having cpu chip inside a cpu chip" that was good for advertising and ease of explanation.... but it was not a seperate cpu processor in itself!!
Now true dual core is a outgrowth and bulit upon hyperthreading technology but they different.... questions I have?
1. is each core in a dual core chip also have hypthreading bulit in?
2. or it has a common hypthreading section that can be used by each core?

I have done some searching and havn't really found any place that reall talks about hyperthreading and dual core together..... and what some of the issue are btween the two and how they relate to various programs and such.... have you????

[Sam Ontario]

For now and future, dual core (or even quad core in the near future) for multitasking!

Most of Intel's PentiumD processors do not have hyperthreading. The Extreme Editions do, and appear as four logical CPUs to the O/S (and the hyperthreading sometimes adds a few percent to their performance). Intel's upcoming Core 2 processors do not have hyperthreading. AMD's X2 CPUs are multicore, no AMD CPUs have hyperthreading.

Aside from fine tuning differences the basic technique of breaking a process up into multiple threads that can run simultaneously is the same for hyperthreading, multicore, and multiprocessor. Almost every program that was designed for hyperthreading will work even better with multicore or multiprocessor.

One can rarely extract an additional 20 percent performance out of hyperthreading. 60 to 80 percent more is common with multicore.

The Intel site explains the upcoming Conroe as sort of a dual core hyperthread..Although not officially called that..
Whether it's market hype or not, they show a total of four threads going through two cores, and getting the same treatment essentially as what hyperthreading does..But on separate instances...

Could you provide a link for that?

[pijetro]

Yeah, look at the Benefits of Multicore demo...And whatever else might excite you..

I didn't see anything there about Core 2 Duo, only PentiumD.

[pijetro]

My bad, the link underneath (dual core demo), had me believing that somehow the hyperthreading offered on the dual core would be considered the Dual Core 2...
I was jumping to conclusions..

Interestingly, it's been suggested that the dual core 2 would be ideal for mobile technology..
It's safe to assume that it'll hog less power..Does this necessarily mean that it would be better for the folks that encode to MPEG??

I just wanted to be sure I hadn't missed something!

There is a mobile version in the works. Most MPEG encoders are now multithreaded so they benefit quite a lot from dual cores. TMPGEnc can run twice as fast when using both cores of my Athlon 64 X2 3800+.

Just saw this about the mobile Core 2 Duo being released July 23:
