which is faster? (processor)

[eSDee]

A friend asked me this question and since I'm out of the Pentium loop I figured you guys would know. Which is faster?

Pentium® D Processor 820 with Dual Core Technology (2.80GHz, 800FSB)
Intel® Pentium® 4 Processor 630 w/HT Technology (3.0GHz,800FSB)*

Thanks much.

hmm i'd guess it depends on the application, but most likely the 820 since it has two cores

I have the first processor (I think) and I was wondering. Will the dual core be utilized to accelerate all applications or just apps that are designed to itilize it? I know for some 3D modeling programs we use (Maya) you have to check a specific box in the configuration in order for the app to utilize dual-core processors.

with current technology (amd is working to change this by making multiple cpus look like one cpu) you can only run a thread on one processor. That means that if a program is designed to run on one set of "rails" sequentially, it can't take advantage of the second core. But many programs use more than one thread and can split up the work on multiple cores. so to answer your question, a specific program must be designed to use a second processor, but that doesn't mean your computer wont go faster since it can push other processes/programs onto the other cpu.

I see I see. That makes sense. Thanks!

BTW, then what is "hyperthreading?"

Hyperthreading

A technology developed by Intel that enables multithreaded software applications to execute threads in parallel on a single multi-core processor instead of processing threads in a linear fashion. Older systems took advantage of dual-processing threading in software by splitting instructions into multiple streams so that more than one processor could act upon them at once.

With hyperthreading, one application can split up it's tasks and the single core can process 2 instructions at the same time instead of one at a time.

With multiple cores, you can potentially run multiple applications which can be separated by core and run independently of each other.

Combine the two technologies and you have multiple applications sending multiple instructions for each core and an overall boost in the processing speed (if the application is properly coded to take advantage of multi core/multi instruction processing. :thumb:

Everything I have read says that the single processor at an equivalent clock rate is faster.

For a single application running... that is true.

Toss in multitasking... and the dual cores start to shine. :D

I would tell your friend to stay away from both and get the AMD X2 or the AMD 64

Like we couldn't see that coming.... :rolleyes:

Umm hmm... sure.


I haven't bought a new CPU in almost 2 years.... so that part isn't my argument.

I haven't NEEDED to buy a new CPU... and I still don't. So put your AMD ePenis away. Ok?

FYI, I have the Pentium D, and I love it. I don't do much gaming, but I love how I can encode a video and still have a super-responsive computer.

[InfiniteNothing]

I think that means your video encoder isn't taking advantage of both threads.

Oh right, without a doubt. Which actually, is fine with me. (You can also set its affinity to a certain processor). I've found that if I have one processor (not dual-core), and I do something like that, my whole system slows to a crawl.

Thanks everyone! :cheers:

[Cubsfan]

Thanks everyone! :cheers:
So which did you get?

[eSDee]

I'm going to recommend for him to get the dual core.

[SnowSurfer]

+1 amd x2

love the epenis...

I sent my friend the link to this thread and he said thanks a bunch, then sent me back this link:
