Pentium D 805 vs Pentium 4 3ghz

[dave518]

As far as im concerened my pentium 4 at its stock 3ghz plays Call of Duty 2 just fine.
I was thinking of buying a pentium d 805, theyre cheap and dual core, if overclocked slightly to a little above 3 ghz how would it compare to the pentium 4 in playing CoD2?

Any thoughts are greatly appreciated, thanks in advance.

It would play slightly better because COD 2 now supports dual cores after the 1.01 patch. Not a worthy upgrade if you ask me.

 

[dave518]

Thanks, I didn't know CoD2 supported dual cores, i always heard people saying that dual core is bad for gaming, i guess not always the case.

Well it would not exactly be an upgrade, the Pentium 4 is in my parents computer, mine cant run CoD2 so I was comparing my parents computer to one I could afford to make.

Overclocked to slightley over 3ghz, with a nice hsf how long could the cpu last, a few years?

I was researching which I should buy, PD 805 vs P4 630. According to all the benchmarks, the P4 has a slight advantage over the PD. I went with the dual core since GPU will be a factor and who knows what kind of threading we'll see in software in the next five years. And I guess the 805 overclocks very well.

It'll last you at least 4

Thanks kingtas, those links were quite helpful. Seeing that the stock P4 and PD are so similar i think a slightly overclocked PD will beat the P4 and that is what i was looking for. Also the Pentium D is much cheaper then the Pentium 4, i think i found a winner.

 

[dave518]

Atleast 4, thats great.

Thanks

What about the Pentium D 820, is it worth the few extra bucks to get that one instead of the 805?

Dave, the higher a cpu's multiplier is, the easier it is to overclock. Since the 820 has a 1x cpu multi advantage, it will require a lower fsb to hit the same speeds. That means less stress on your motherboard, and less stress on your RAM. To me, it's definitely worth it. I always buy the highest multiplier cpu that I can afford. You might want to consider a 915, though. It comes with twice the L2 cache, and is 65nm, so it will run cooler.

Say what????

The Pentium D 805 runs at 20 x 133 = 2666 mhz. The Pentium D 820 runs at 14 x 200 = 2800 mhz. This makes the 805 MUCH easier to overclock.

 

[dave518]

So with all that said is the Pentium D 915 still the best choice of the three?

And also how do I find out what the multiplier of a cpu is? and what is this math,

and where are the numbers coming from?
I know im sounding like a real moron, but I gota start somewheres

Thanks for all the help guys.

To figure the multiplier number, simply divide the actual speed in hertz by the true cpu fsb setting in the bios. 2666/133 = 20. If a cpu is rated at 2.666 (megahurtz), move the decimal over 3 places and you'll have the hertz rated speed.

 

[dave518]

Thank you very much, thats quite helpful.

I have a 805 and it does ok but I can only get around 3Ghz.

If you can afford a little extra I would go for the 915 and some high speed ram.

But either way go dual core, your choice.

 

[dave518]

Thanks for the input so I can see an actual user of a 805 and how well it does.

Yea, I reckon I will go for the extra money and get the 915.

PS: It won't make your game run any better as it is nearly guaranteed to be video card limited rather than limited by the processor.

I upgraded from a 530J to an X2 3800+, large diffrence in a lot of games. I tried underclocking the processor, it does make a diffrence, just not in all games.

Haha! I have a really bad memory, htne. I completely forgot that the 805 had a 133 FSB. That said, I still like the 9-series better. They run more than 10°C cooler, overclocked or not.

My 805 ran at 3.7ghz on a scythe ninja. What motherboard are you planning to use? What memory? Have a good power supply?

 

[dave518]

I haven't really gotten as far as those things, just lookin for a good processor first. Also what AMD chip would be equal to the Pentium D 915 so I can compare?

 

[dave518]

What memory and motherboard would you suggest, and how good of a power supply will i need?

 

[Markfw]

Try an X2 3800. It will wipe the floor with the 915.

 

[dave518]

Even at the lower clock speeds or if it overclocked considerably?

Edit: Well after checking out the CPU comparison link from above it looks like stock it wipes the floor with the 915.
