Pentium D 915 vs Pentium D 820

915 runs cooler and overclocks better. It has a slight performance edge over a similarly clocked 8xx series.
Why are you considering buying either of them?

They're both sucky chips compared to the Core 2 Duo series. I'd only consider them if I was upgrading a system.

im considering them because im trying to keep the system im putting together under 750 dollars

the system im currently using is fairly old and more importantly, not mine

im trying to get a decent budget / gaming pc setup and with the mobo i have picked out if i ever decide to upgrade to a c2d i will be able



are you saying the difference in performance between these 2 chips is minimal? would u recommend one or the other?

Processor Number Δ 915
Architecture 65 nanometer technology
L2 Cache 2x2M

EIST(Intel SpeedStep Supported)?

Vs

Processor Number Δ 820
Architecture 90 nanometer technology
L2 Cache 2x1M


My Opinion 4Mb Unified L2 Cache and then 65nm(Energy Savings) and EIST as it ways will lower and Dynamically Alter your Specifications to save you CPU life and CPU Energy waste.
Go for the 915 If Absolutely cannot choose Core 2 Duo.

If you want to build a decent but cheap PC, get the E6300, or get a X2 3800+; they may be few $$ more than Pentium Ds but:
-perfor better
-overclock better
-run cooler (consequently quieter)
Pentiums are old stuff; they've actually become since K8 moved to socket 939 2+ years ago but the current price drops and advent of core2 CPUs, makes it really pointless getting a Pentium (D) CPU. The extra $20-30 a X2 or Core2 are nothing compared to $750, especially taking into account the performance boost they have over Pentium Ds.

Usually i hate to suggest this but sometime this or next month intel will release the e4300, a cheaper core 2 duo that might just meet your price expectations. Do a little google search and check it out.

i realize this is going to be offtopic, but for 750 dollars what combination would u suggest i get instead of the 820/915

for

case-
psu-
processer-
mobo-
video card-
memory-
hard drive-
heatsink/fan for processor-'

i already have a monitor, keyboard, mouse, dvd burner and sound card

If you still need to decide between those I suggest you pick the 915. 9xx series are better than 8xx series.
Also as the others say, you might also consider the E6300 which is really cheap since you want to stick with Intel.
Or at the latest, you can also wait for the budget versions of the new Core 2 Duo processors (conroes) which one of them is the E4300 and performs really good for the pocket.

i didnt exactly specify intel or amd

the best value pc for ~750 with some upgrade ability would be cool

if ya guys would like i can post what i currently have put together

otherwise ill just go with the 915

Post what you have in mind to buy so we can maybe recommend you something better or give you some tips. :wink:

Are you going to be gaming?

E6300 - $193
Biostar TForce965PT - $105
G. Skill 1gb - $115
Biostar 7600gt - $126
FSP Group 450w psu - $54
NEC 7170A - $30
Western Digital 160gb HDD - $54

Total - $667

Pick out a case and your set. Stock cooling is fine, if your not going to oc you can save a couple bucks by getting 533 ram instead of 800. This is a pretty good case/psu bundle, you could save a little cash if you go with that instead of a seperate case, but the FSP Group psu i suggested is a little better, quality wise.

Oh yeah BTW, now that we are talking about C2D, I have a question. Why have they increased in price? ZZF had the E6600 for $312 and now is in $322. Same case for Newegg. Whats going on?

I dunno, when i got my E6300 it was $181, now its $193. I wonder if it'll hit $200?

Damn, Intel will take every single dollar they can from us!  

As has already been stated, you want to go with the Core 2 Duo. :wink:

But if that's not possible, go with the 65nm anything (in this case the 915). Finally, whichever way you go, wait and see what Intel announces this week at CES in case it might have an affect on prices.

Sure they probably would likely only drop a few bucks at most ... it still pays to wait and see, no?

-john, the redundant legacy dinosaur

Market rules; they always upper the price for something that is really sought after. My 4200+ also went from $178 to $189.
Nice price list to show; there's really no reason on land to get a Pentium D anymore.

Agreed with everything said in this thread - the PD series are just terrible processors. They run hot and perform poorly.

If you can't stretch the budget to a C2D E6300, the X2 3800+ is worth a look. It's still a bit pricier than the cheaper PD chips but performs much better.

Exactly!, you can prove that by going into Pentiums sections, they are dissapearing more every day!

yes, i plan on gaming

i think im going to go with what you suggested

E6300 - $193
Biostar TForce965PT - $105
G. Skill 1gb - $115
Western Digital 160gb HDD - $54
FSP Group 450w psu - $54

and i ended up choosing these to go with it

cooler master case - 49.99
geforce 7900gs -184.99(-40 mail in rebate(i make sure to check in with them on these so i get my money, some people see rebate and forget to do them ))


which ends up total - 783.77 w/ shipping
743.77 w/ rebate

looks good to me  

To be serious, that sounds way much better than any Pentium D built.

Good for you if you get that rig
