Hello I have recently begun looking for a new computer and decided I can wait for Nehalem to be released, but I am not entirely sure about it.

What will be the differences between the 45nm chips and the 32nm chips? (also price difference)

Could a DDR3 motherboard that supports Nehalem 45nm support 32nm Nehalem too?

If I bought a new computer in say about Q1 or Q2 of 2009, how long could the computer last me? As it would be a pretty good computer that I purchase.

The socket should probably be the same, so yes, it will be compatible for both chips. The 45nm will be out around Q4, the 32nm won't be out for a year after that, so it'll be a while. I'd also say that a reasonable Nehalem system in early 09 should last you a couple of years, easy, depending on how much top end you need. The E6600 was one of the first C2D's released, and it is still a reasonably good performer today, so that should be some indication.

I'd wait for the 32nm versions. Likely to have a higher IPC (better performance at the same clock speed) and dual die versions would be out by then as well. Plus less heat / power consumption means better overclocking.

They won't be out until likely Q4 09 at the earliest though, and not mainstream until later. I don't know if that's worth the wait or not.
July 22, 2008 5:49:38 AM

to my knowledge, the 32nm nehalem would be in an octo-core version as well. gonna be a loooooooooong while before these things hit mainstream. and prices go down.

If you are going to wait for the "next big thing" in computing, you will be waiting forever. There's always something bigger and faster coming down the pipe.
July 22, 2008 7:58:32 AM

So I guess i will just wait and get a 45nm 2.6ghz or more Nehalem, than further along the track il buy a 32nm if there is a big change. Thanks for your help guys.

Nehalem is going to be expensive for the first 12 to 18 months after it comes out. The boards will be more expensive, the ram DDR3 will cost more, and the CPU will be over priced for at least 6 months to a year.
My price guess for these 3 parts needed for a good 64 bit system will cost between $800 to $1000, board, 8GB ram, and the CPU.
I'll prolly look at a Nehalem system after AMD starts to sell it's next great thing after Nehalem comes out. When Intel cuts the price in half like they did with the Quads last year.
July 22, 2008 9:28:53 AM

Il be fine with just getting 1 - 2 gig of DDR3 ram, and the 2.66ghz Nehalem will be about 300-600$. I'm willing to pay that, as I can always just stinge on the other parts like ram and graphics card.

Though 8 cores are getting a bit stupid now, anything after that and we should expect CPU's to be raising dead.

Sorry but i cant dish that much money for a CPU. 200€ is my limit. For a GPU, well, that that limit i a bit higher. ill pay even more for a mobo if it is worth it. But 600€ for ONE cpu. No, completely out of the question.

And it is a terrible investment also.
July 22, 2008 10:56:08 AM

I can wait until the Lynnfield with the LGA1160 ports. But will these work right with the graphics cards that are made like 1 year later and the ram too.

Also when will it be a good time to buy a Nehalem Cpu? I just want a good gaming rig, that can last me about 4-5 years (and I would upgrade the ram and graphics card some times). Is it worth to wait for Nehalem and which Nehalem?

the nehalem socket is 1366 pins, therefore 100% incompatible with current boards out today.... IMO if i was gonna make a system now, i would get either a E8400 or a GOOD Q6600 (clock it up to 3.0GHz no voltage changes and ya good to go :kaola:  ), a nice P45 or X38 and one or two HD4850's :)

Total: 827$

That value counts the 4850 Crossfire. So, there is still money for a nice cooler, and a case if you dont want to reuse yours. I didnt included HDD, because well, you can reuse your own HDDs aswell. Ive been upgrading for some years now, and my Boot HDD it is still a 80 GB Special Edition from Western Digital. I got another of 750Gb i bought recently, but hey it was a great deal. Same for the DVD-RW. Reuse yours. Mine 4 years and still working flawless. Illl buy a BD-RW when BD Discs are cheap and BD-RWs are also cheap. I hardly use CDs/DVDs anymore. From Hard disk loading to External discs, hell, dont need no BD Discs.

Hope i helped. You can find better deals im sure, but was just to show you can mount a very decent machine for less 1000$.
July 22, 2008 11:49:59 AM

But I just want to know, if I bought say a Core2Quad 6600 core system with a nvidia9600gt, 2gig of ddr2 ram and other good stuff, how long would this last me?

I have a feeling that Intel might pull another chipset compatibility trick and force you to upgrade to a "compatible" chipset just so you can chop off a few nanometres.

EDIT: I meant Intel, I don't know why I said Nvidia.

As built? The rest of the year. You could use a better graphics card and more RAM.

Of course, i'm the maniac who spent $4500 getting 4GB 1800 DDR3, and a 3.2 quad...I plan to wait out the next socket change, because I don't believe there will be that big an improvement in proformance over the next few years, at least the way chips are currently designed.

@dommzyboy: ur processor will last a while....specially if ur willing to OC. however u might have to upgrade ur ram and gpu depending on what screen size u game on and with what level of details

nehalem uses new sockets altogether.....so no u cant use dem on current MB. and its not worth waiting for nehalem as they will be way too expensive and according to a review in tomshardware, 2.93Ghz nehalem is a bit faster than 2.9 intel quadcore and about 12% faster than a amd 9950 OCed to 2.9GHz
July 22, 2008 12:49:48 PM

How can anyone decide which is better or if Nehalem is worth it at all? It's not out yet, so until it is there's no way of knowing

From what I have heard the octo core will also be naitive. The desktop wont get it until 32nm but I think the server will get it at 45nm. I know Dunnington (naitive 6 core Penryn based) is coming out before the end of this year for servers.

He was asking if the socket for 45nm Nehalems, LGC1366, would be compatable with the 32nm Westmeres. I would think it would more than likely be as the Northbridge no longer determines the MC that is now on the CPU so it will be much like AMDs current setup. The compatability will be there and up to the mobo makers to update the BIOS. Only you wont be able to use the newer features of the chip in a older mobo unless Intel sets the X58 up for future chips but I doubt that.

In my own personal opinion I would go for the 32nm die shrink. It will be much like Penryn in it will offer power and heat improvements there will be some more advanced instructions (possibly a new set of SSE) and probably a much more refined process that could mean higher OCs.

Because I understand architecture; We're past the days where you can get from 333 MHz to 3.33 GHz in a decade. At this point, if you want more processing power, its time to re-design computers from the ground up. If Intels top new CPU is 15% more effective than a Q9750, I'll be shocked. Is that worth spendind Over $1000 (probably $2000 when it comes out)?

As for more cores, they help...but I forsee major bottleneck issues in regards to RAM, limiting extra cores much past 4...

Of course, I could be wrong and you could get an extra 25%+ due to an architecture change, I doubt it though...

^Servers. Servers can always use more cores. And whatever the servers get trickles down to us consumers because its easier when Intel produces one type of chip for all.

Of course Intel is going 6 core first and I believe AMD is as well. but still. Whats easier will also mean what will end up cheaper too. Not their fault software companies are freakin lazy.

Of course, if all software people knew what they were doing, all 32 bit applications would work flawlessly on 64 bit machines, and we wouldn't have all these driver issues...(and yes, it can be done, and done easily too.)

July 22, 2008 2:46:38 PM

My understanding from the engineering samples is it's up to 25% faster than current core 2 clock for clock. It's also rumored to overclocks like mad. There is nothing I've seen that sugests it's a slight bump in performance and some claim, though I doubt them suggest a 50% boost.

^Thats based off of Anandtechs preview vs a Q9450 @ 2.66GHz. In some apps on a clock per clock basis it got 50% performance increases.

And yea Intel keeps stating that some of the chips they have shown off are OCing like mad. But thats to be seen.

The OCing may have been (still on unfinalized hardware) but the Anandtech review was on a Foxconn mobo so it wasn't Intel bragging.

Funny how Intel never mentioned how we would only see that 10GHz performance in certain new application.

AFAIK they (the industry in general) has semiconductors operating at High Microwave frequencies. What stops Intel (and others) from designing Logic ICs that work in this regime?

Very nice build there. I'd replace the MB with a 790FX though, just to get x16+x16 in Crossfire instead of x8+x8. Check out the MSI K9A2 Platinum or the ASUS M3A32-MVP Deluxe.
Another benefit you'd get with those two is that they support the latest 140W Phenom 9950 BE (just in case you decide you want a quad later).

it depend whether the difference is like:
PD to Conreo
or
Conreo to Penryan
The former was revolutionary.
but the bottom line is dont keep waiting for the next big thing, because it is a while away and when it come it will be really overpriced, and you'll be like 'but im gonna hold out til 45'. you could build a 45nm machine now and be happy with it and that would start to feel a little long in the tooth roughtly when 32nm are release and have gone down in price a little.
July 23, 2008 3:27:10 PM

Technology is great, but I'm not a person who buys just because it's the latest. I'd rather have full use out of my machine to a time when Its no longer capable of what I need, then I'll upgrade.

I agree with what's been said, it's not worth waiting for technology because there's always going to be something better.

The quantities are different not because it is DDR3, but because Nehalem, specifically the top end ones, will have a triple channel controller instead of the current dual channel.

I'd also say that a reasonable Nehalem system in early 09 should last you a couple of years, easy, depending on how much top end you need. The E6600 was one of the first C2D's released, and it is still a reasonably good performer today, so that should be some indication.
