D945 vs E4300

More ram does matters.
E4300 is roughly a P-D 960...

Which mainboard do you have?
E4300 has the same FSB speed as Pentium D. So it is possible that the E4300 will work.

Anyway, if your mainboard does not support E4300, then the PentiumD 945 with 2GB is better choice.

I think the major problem is the VRM of motherboard.

Thanks for the input   ,

I do allot of gaming, graphic design and 3d modeling, so i want to make sure i get the best performance for my money, and i am in no way concerned with power consumption, or heat.

Also i am not concerned with the upgradeability of the system, i will only be running this setup until this time next year.

EDIT:

I have the GA-8N-SLI rev1.1 Motherboard, its cpu support list doesn't show the core2 chips as compatible.

hey u can go wid e4300...i have mine p-d 945 and e6300... e6300-at stock while p d 945- (230x17)-3.9ghz cant beat e6300 in gamin xcept some graphics and office application
both hav 7600 gfx and 1gb crosrair value ram

The motherboard is not compatible with Core 2 Duo CPUs.

But the major problem is the motherboard support.

i will suggest u take a cheap mobo (tht can max out till 350fsb) and buy only 1gb ram (take TWINMOS for a cheap quality). u shld not take a ddr2 800 jst take a 667. its enough for a e4300. or do this thing buy a water cooling set and buy pentium d 945 and overclock it till 4.5ghz use 266*17. this will beat a e6600

I would love to see a benchmark where a D945 was even close to E4300. In rendering the E4300 is at least 20% faster. In most other it ranges from 15% to 40% faster.

As for the ram the jump from 1 to 2gig will make difference but not that much in XP. In Vista it would be closer but still E4300 would be noticeable faster.

hey srry i meant e6300 ( i was xcited  

ok,
some more info:

I already have 2x512 dual channel ddr2 800

If i get the D945 i will have enough cash left to get another 2x512 of dual channel ddr2 800.

If i get the E4300 i will have to spend the extra cash on a new motherboard.

Also i will be running xp.

So, with no over clocking which will give me the best performance,
D945 with 4x512 dual channel ddr2 800
or
E4300 with 2x512 dual channel ddr2 800

I guess what is throwing me is this:

How can the 1.8GHz 800MHz 2MB E4300 be faster than the 3.4GHz 800MHz 2x2MB D945?

How much were you planning on spending, total?
Can you wait at all?
Willing to consider a, ahem, "budget" mainboard?
Upgrade plans?
At newegg you can get the gigabyte ds3 for around $130-135, the E4300 for $179 and memory a little over $100. So, you're looking at $310 or so for the board and CPU.

A budget board such as the ECS (I know) 570 SLI-T (hey, it's got good reviews) can be had for $69 after rebate. Paired with the E4300, that's around $250, which leaves you only $40 short of memory, too. If you can wait a little bit (or spend a little more), the prices may come down to where you can get all three.

In any case, I'd go with a Core 2 system for upgradability. You can always buy more memory.

Totally different architecture.

You cannot compare the frequency alone.
For Intel Netburst CPUs vs AMD K8(L) CPUs vs Intel Core Arch. CPUs.

I have about $600 and i have to spend it today or my wife will make me spend it on household junk.
also i have to spend it in a way that will allow me to upgrade multiple pcs, and get a 500gig sata2 drive for my machine, and a new micro case for our tv pc.
Ahh...
my head hurts from all of this.

I was planning to buy a D945 and more ddr2 ram, and put that on my old board in my pc.

Then take my old D805, an agp card and some ddr i already have, buy a cheap 775/ddr/agp motherboard for that stuff, and put those parts in our tv pc.

Then take the old 2.8 478 p4, and motherboard out of our tv pc, and some more ddr that i already have, and put all of that in my daughters pc.

Then take the old p3, and motherboard, and sdram from my daughters pc,
stick those parts in a cheap case, and donate it to a friend.

Ah...
The cycle of life continues.

You're kidding, right?

How does a much lower clocked AMD SPANK the P4? It's all in the architecture. Why would Intel go BACKWARDS in performance? They wouldn't, they didn't. They built a better mousetrap. It spanks the dual core Athlon that used to spank the P4.

A bigger engine with a stock exhaust actually makes you s-l-o-w-e-r.

Nope, for all i know the new chips are designed for lower power consumption.
Thats why i am here asking.

But for my pc "cycle of life" to continue correctly i think i am gonna have to get the D945.

Bleh...
Either way i go will kick the crap outta the D805 I've been cooking.

It really depends on what applications you are using and how memory intensive they are. If you are doing things that do not really benefit from the extra 1 GB, then the E4300 may be the better performer.


OK, but if/when Intel drops prices again around May/June as they are expected to do, I think you'll be kicking yourself that you spent money to basically drive another nail into the coffin of an outdated system with little to no upgrade potential. :wink: (Just IMO, of course)


Hiding the money and then using it to upgrade 3-4 months from now is not an option, is it? Then again, that would be wrong ...

Sell your other crap, and update your pc with the money you getting from it for a e4300 with a medium board that could take quad core for the future. And for the ram yes 2GB is good but i have 1GB DDR2 800 and i still dont use 100% of it, gaming, rendering etc, this is depend also of the quality of the ram. Cheap ram will bring you less performance.

well,
I bought the D945.
It was the only way i could work it out to where i could upgrade all of my machines and only have the old p3 parts left over for the pc to donate to my friend.
I used most of my tax return to pay off my car, and the rest for these parts.
Next year I will be able to spend the whole $4000 return on a new machine.

Well, that will work great too.   What with the 45nm metal gate/high-k announcements, it looks like there is going to be some really impressive hardware out there a year from now. (Certainly going to kick the butt of whatever I manage to (finally) buy this month :wink .

Now i know the E4300 is better, but i couldn't fit it into my budget/requirements.  

Thanks to everyone for your input.

wrong, fsb doesn't mean anything for intel cpus, jsut because the 4300 and pentium D's run on the same speed bus doesn't mean the motherboards are compatible, it's the northbridge that matters. You need a 965x (anything) or a 975x/xbx or nvidia chipset to run conroes/allendales, the bus doesn't mean squat.

And there is no doubt in my mind that the 4300 is the better cpu, wait another week or so, and the inflation will be gone, the 4300 should end up at about $140 in a few weeks, that will make a it a real steal and the next s 805 in terms of ocing. Now if you can't afford either of these two boards, then I don't know what to say about choosing a $150 cpu

The ds3 is a great board for overclocking, and it's cheap. People are getting the 4300 to 3.4ghz on stock cooling if that means anything to the op, combine it with a nice cooler ***cough***Tuniq Tower*** You'll be having an excellent oc for a cheap cpu that outperforms the x6800 in every benchmark (we're talking stock x6800, don't confuse the two  ).
And here's not what I'd call the greatest board, but its cheap and that's what matters for budgets, but the ds3 is a far better board without question

Any questiosn

I'm voting for the 4300. If I couldn't get that chip, I'd just save the dough for another day...

The E4300 without question.

The D945 used to run hot and of old architecture :roll:

Get the 4300, there's no excuse on price because the price will drop to about about $140 soon
