Pentium D or Pentium Dual Core?

[Suprchargd]

Core architecture pwns Netburst. Former D805 owner here.

Don't know about that load temp of 42C on the D945, Speedfan must be way off.

My pentium D 940 @ 3.6 ghz made 1034 points per day folding@home. My Q6600 @ 3.6 makes 3250 ppd. So twice the cores makes over 3x more points.

A Q6600 can be had for $270, and a pentium D 925 for $50. So 5x the price for 3x the points; now its getting a bit more interesting.

I would go for the $99 Gigabyte board

using a thermalright $35 heatsink,

you need the adpater below the heatsink listed.

That makes your build $190 with a dual core and great performance for the price. I use that same heatsink on a quad with good results so it can be used to upgrade later if you went to a quad. The mobo overclocks well and the CPU is dirt cheap.

Excellent point and links.

Yah so if you wanted to make up those points... you would still spend less on CPUs.. .but you spend 3times more on ram, motherboards, power supplies, harddrives (cases?) and electricity...

i cant see suggesting a horribly inefficent design... in the long run that P4 would cost him more money in powerusage then the lower in core duo. the long term benifits of getting the E2140@3ghz out ways the short term lower cost of the P4.

65W vs 95W = $15/year difference running 24/7 @ stock. Not a lot of savings there. E2140 to 3 ghz is a 90% OC, the 925 3.0 to 4.0 is a 50% OC, so now its 120W vs 127W, so there is no power savings at all.

No question the E2140 is better, but for someone on a budget, the extra $25 matters. So for a 50% price increase you get maybe 60% more performance at most. But you get 1/2 the cache so in some cases your speed increase might only be 30%.

If you are ultimately planning on a drop in quad, then the p4 925 is a cheaper throw away.

your math is WAY fuzzy, 59.99 to 74.99 =50% ? i dont think so

even retail box at 74.99 is not 50% increase. even then he doesnt need a TR hs to hit 3ghz oc, he can do that with the stocker on E2140. that then saves him further money for something else. like better ram/mobo or even video card....

newegg is the only one that is reversed.
PD 925 $99

E2140 $74.99
http://www.newegg.com/Product/Product.aspx?Item=N82E16819116037

about the only area the extra L2 might help the PD is in encoding, even then thats strechin it...

either that or i would look at ebay for about $75 you should be able to find the E4300 with 2mb L2....

bench transcodeing dvd of terminator 2 se
E2140 stock = 11.05 min
vs
PD 930 stock = 12.35min

the 930 was the closest he had listed to the 925, as you can see even the 2mb total extra L2 didnt help.

also you cannot compare TDP's to powerusage drop... both QX9850 and QX9650 have the same TDP and same cpu speed. the 9650 has 12mb vs 8mb on the 9850 for L2. yet the 9650 is lower in powerusaga by 6.3% at stock by this link here.

this one shows it to be a bit higher % difference on load
http://www.legitreviews.com/article/583/11/
you get the idea...there is more that goes into the cpu to improve power usage then TDP numbers show... now given if the op ocs the PD,it will use way more power then the "core 2" based cpu will oced.

I pointed out you can get a 925 for $50 from tigerdirect. And you quote the 2140 as $75. The difference is $25. $25/$50 x 100 = 50%....seems clear.

as you can see even the 2mb total extra L2 didnt help.

Sometimes it helps lots, sometimes it doesn't help much. If you SMP fold on a CPU with 1 meg of cache you can almost double your production if you fold with 2 megs of cache. When the application can fit entirely in the cache you can see a big increase in speed. If not, you have to use ram which is considerably slower. So, as I said, sometimes less cache is a real killer.

umm the cpu is not $50 but 59.99 making it basicly $60, so 60/75=.80,100-80=20% difference in price... even if we use that math, 60-75=15,15/60=.25*100=25%

*edit*
wait wait, thats 59.99 with MIR, price is 79.99. making cash out of hand 925 only $4 more then the E2140, its really up to the OP.

im just tring to offer the rest of the picture. there was a reason intel stoped tring to fix netburst and you see why in the numbers...

We must be seeing different prices; says 49.99 for me.

No question the E2140 is a better CPU. The only question is at what cost for what performance. At 50% more cost for maybe 60% more performance, it's not quite as clear for someone looking at bargain prices. If you want to save $25, get the 925 and later buy a quad and just drop it in; you save some cash for a small loss in performance that probably would never be noticed unless you were folding and using your machine 24/7.

well im using the link from your above post and get this....did you use a PP link thru to get a extra $10 off or something?
http://img.photobucket.com/albums/v733/Evilsizer/ocforums/NewBitmapImage.jpg

just assume for a sec though he wont waste his time with the MIR. does it then still make it that better a vaule vs the E2140?

They must like me better than you I just click on the link I provided and voila, $10 off. Weird.

I assume he takes his $20, otherwise he can sent it to me if he likes.

 

[Evilsizer]

well my POV is that cash out of hand is still cash out of hand... 6-8wks to get $20 back, umm its ok.. $5 difference even with the extra $10 off. i think in that small difference the E2140 is the clear winnar!

LOL, well if he likes your math then an E2140 it will be.

Ok this is off the topic sort of.....Between a C2D E6300 I believe and My Pentium D even though the D has a higher clock speed and more executions per seconds but which one would do that folding faster......the C2D is my wifeys and that thing just seems sooo slo at all it does, has 2 gigs or pc6400, so it's not hosing up with the ram.... Could that E6300 Overclock to somewhere in the 3 Ghz range with proper cooling and power amd mobo? Ok back to trying to get my Pentium D to Fry and egg.....

my e6300 is doing 3.15ghz atm easily on some mediocre cooling. and gets a 10s faster 1m super pi time and nearly 1000 more 3dmark06 cpu points when compared to my PD945 @4GHZ

 

[Evilsizer]

well consider that the E6600 @ 2.4ghz stock only gets matched by a [email protected]. netburst was designed to get better with higher clocks. it is a very ineffcient design to get work done per clock cycle. my old dothan box pre core/core 2, running at 2.4ghz would out do my P4 [email protected] in just about everything that i used it for.

 

[54lariat]

Sam what mobo are you running on your e6300...I bought mine with a mobo combo from frys a while back and it is the worst ECS board I think they ever made, no options at all...which I found suprising since the ECS board I use with my Pentium D has most options u need....

Thanks

I have a brand new mobo in my stock room for two socket 370 PIII CPUs. Two CPUs! I'm thinking of sticking two 1Ghz CPUs in it & building it up.

How fast can I go, General? I have four brand new 1GB PC-2100 sticks in stock, and one brand new 1GHz 370 (6 used, but identical) in stock!

Whoa, I've never seen a socket 370 motherboard that takes DDR. Awesome.

I say forget the Coppermines and toss a couple of Tualatin 512k processors in there with some older Socket A heatsinks. Or, go for some Tualatin-based Celerons, as they might be easier to overclock. All of those socket 370 chips are incredibly cheap these days, I've seen Celeron 1200 Tualatins for $5 a piece at a local computer store. A cheap DDR2 board with an E2140 or E1200 would probably still toast it performance wise, but this would be more fun to build up and mess around with IMO.

I think a single pentium 4 would smoke two coppermines. No question any dual core AMD or Intel chip would definitely smoke a couple coppermines, even the nice ones. (1.4 GHz or more) Sorry to disappoint you but your not going to see much performance out of a system from 2001 Even with SMP.
