Nahalem opinions
Forum CPU & Components : CPUs - Nahalem opinions
What do you guys think about nahalem. I don't know, but i feel like this processor wont really do much for gaming compared with already available processors. 8 cores will be overkill. What exactly does the memory controller do for the processor anyway?? It will come with HT too. It sounds good, but will it be any good. If it is so, then expect the prices to be very high.

Well, an integrated memory controller should improve memory performance, but as we already see that doesn't help AMD processors much in games.
I think it will be good. Intel is biting off a lot here, but they'll pull it off. I wouldn't expect a P4 => Core 2 jump, but it should be decent.
As for prices, I could see them being high, especially early on with the first releases.

6Agreed. Im interested more in the OCing ability than the IMC and QP (QuickPAth smiler to HyperTransport) and HT (Remember P4 HT?)

Actually, the IMC helps gaming a lot with K8, compare it to K7 which was the last FSB based AMD CPU, gaming performance is much improved.
Core 2 performs so well in games due to its massive cache, as well as having higher IPC. Would it perform even better with an IMC? You bet.
Intel is actually touting Nehalem as a bigger leap over Core 2, as Core 2 was over P4. This is under multithreaded performance, there are claims performance is 40 - 100% better, which would be incredible if even half true.
I hope your right epsilon, I actually dont expect to see any great OC results. I mean what more do u want the E2100 can overclock by almost 100%. I mean a full Ghz speed increase is very common, while AMD struggles to ass just 100mhz to their CPUs. I wonder why Intel doesnt do like nvidia and play dead for a while.
Reply to DarthPiggie
No more FSB, that seems it could provide a lot better bandwidth options.
I dont see the FSB on current core2 arch as a limiting factor. Although sythetic benchmarks show that AMD usually comes out on top in memory bandwidth Intel's arch still comes out ahead on everything else.
Unless programmers start producing better multicore software i cant see Nehalem being that much more over the current Core2. However, if all software by that stage is highly optimised for multicore of course Nehalem will kill anything else out there.
As for Intel playing dead... who said they wont? Current 45nm Quads didnt seem to hit the market with the quantities that the previous gen, and they still have plenty of time to delay Nehalem if they want to.
Reply to chookman
at " accient FSB architecture of intel is somehow the only hold back in the memory subsystem.but in game and many application the memory bandwidth is already good enough.but i wonder if that will effect the overclocking of the CPU as everything is integrated into 1 chip as heat would be a problem.
also another thing i worry about is that would it be mature enough at the 1st generation.but the ist gen or Core 2 is very successful!hope that will continue.i wonder what the AMD Shanghai core is like!
how the overclocking would be done?would it be like the AMD's?different multiplier for CORE,"HT LINK",MEMORY many interesting thing to find out!
Multithreading is SLOWLY getting here (in some areas more than others). The new AMDs and Intels will be so similar now. Maybe they will make a unified socket

I'm thinking the IMC will help them more in the massive multi-processor server arena, especially with the planned 8 cores handling 16 threads via Hyper-Threading that Nehalem is supposed to have. As for gaming, I doubt it will help at all, since games don't seem to take advantage of multi-cores well yet.
if Hyper threading is successful this time round and games and OS can take full advantage of it.then games could have much more physics in them as the CPU is able to process more data.but more then 2 core is still not much of a advantage at this time.
hope things will change sometime soon.

I think it will help games in the long run because if Intel supports it, they will come. I say that as an AMD fan. Developers develop for the lowest common denominator and then work up from there, which is why we've seen several developers kvetch about Intel's IGP failures.
Intel sure hasn't failed on the CPU front lately, so I expect games to eventually benefit more from an integrated memory controller. As for "8" cores, hyperthreading can be turned off if it impacts a game's performance. Presumably, there will be dual core versions of Nehalem, and if yields aren't perfect, maybe triple cores as well, so hyperthreading can be useful at the low end.
If I remember right, a dual core gave a 10% performance boost in Oblivion framerates when it arrived, and hyperthreading gave a 5% boost. I remember that from dev discussions on Bethsoft's own boards. So, some games of recent years have benefited from hyperthreading on the old single core CPU's. It can't hurt with dual, triple and quad cores as well.
I look forward to Nehalem, even if I go Deneb. It's a step in the right direction for Intel. Ideally, they should have gone with an integrated memory controller on their consumer CPU's years ago because the number one company should be a leader in technology and not just follow once they feel that the market is there. Note for fans of old Intel projects, I'm talking consumer CPU's here, not anything on the drawing boards not brought to market or implemented outside of a specialized or server environment. I know Intel conceived of many things first, but they let the market wallow with an attitude that "they don't need this now". Sort of reminds me of Microsoft on the OS front.

They did before, but you'd have to remember low insertion force sockets. I forget what the pin count was.

The single threaded performance will be the 100% gains and the multi threaded should be about 40%. But remember that this is not just a Core2 with a IMC slapped on it. Its a whole new architecture. The reason single threaded apps may see a big boost is b/c of the dynamic OC'ing Nehalem is supposed to have.
That means that when a single thread is being run other cores will under clock and the core processing the thread will overclock to attain maximum single threaded performance. So games could see a bigger boost than you think.
I would only hope this would go for the dual core optimized apps and games. Imagine having 2 cores at 2GHz on a 3GHz CPU and the other 2 at 4GHz just for that game like Crysis.
Personally I think it will turn the tables on AMD. AMD will no longer have the Nitive Quad or IMC bit. It will be whatever performs better on an IPC and price level.

I still think that Penryn is just a 45nm warmup for Nehalem. It just seems like it was there to get it ready so Intel could improve the process and yeild that way when Nehalem hits it will be cheap, fast and efficient.
But this is to be seen really.

And that likely has AMD bleeping their pants.
AMD strong memory lead really helps in the Server arena.
Historically we go XEON for most general purpose servers, but our large VM boxes are all AMD due to their memory performance. If Intel significantly closes that GAP, AMD will be really hurting.
They got tagged last quarter in that area, but I think will do much better this one now that they are finally shipping the B3 Server chips. But things will start to look real tough again late this year.
its not good theory.
Reply to zenmaster
Interl needs it for the server arena...In the desktop area they realy don't but in a server enviorment all those added bonuses that come from Nehalem would help them gain even more market share...remember how much they gained becouse of the TBL bug that held the opterons back 6 months
Reply to T2bus
Nehalem is going to be a sad disappointment, I'm afraid, because of advertising people and fanboyism.
It'll work beautifully, it'll blow everything else out of the water...
...and because the market will have believed the lies, the PR and the hype, it'll be 'crap' because 'it was supposed to be more (insert adjective here) but it isn't!'
Seriously, though, Intel getting off the shared-bus architecture is a good thing. That has really been holding them back.
Reply to mugz
It's not like games use a lot of memory right?
Of course, the extra bandwidth will only save a couple of clockcycles right?
What about latency? You think having to wait half as long for a memory call, wont help?
Oh, you bet nehalem is going to bring huge improvements.
On top of that, it's supposed to have better data throughput and more pipelines for higher speeds.
8 cores? Rofl , seems to me that Intel is assuming the general public are morons , lol."Slap more cores on it and charge 3 times the amount for it and we'll be rich!"But seriously as we all know the software for multi core proc's are not even close to catching up.This 8 core monster would be a great server chip , but in all reality it'll offer minor performance gains in gaming and general use.They're jus pulling what they did in the P4 days , Hype the Ghz to sell chips.
IMC is a "about damn time" idea , i'm gonna err on the negative side until they release the chip and we get numbers , but for now it's looking like a server chip hyped as the next uber goober dodad that we all have to buy to be l33t.

You can only be 1337 if you're 14, exclusively play games on the PC, and think you can assemble and maintain one. Otherwise you're just leet.
As for gaming, well, buying a Nehalem for gaming is a criminal waste. *flexes radiator in anticipation*

Indeed.
There has been talk of them releasing an MCM Shanghai - called Montreal. It uses a hypertransport link to communicate between cores.
*see here => http://download.amd.com/Corporate/ [...] ystDay.pdf
More interestingly... Propus. Now a question - how much of the die is taken up by... say... 6MB of L3 cache?
Would it be possible to put 4 Propus chips on the one die? That would give you a full 16 core CPU... on the one socket.
The question of course would be data exchange using only 4x Hypertransport3 links - you are limited to a single socket server unless your willing to take the performance hit on double hops for information between cores.
Really, you'd need 8x links for a dual socket workstation, 16x for a quad socket (but thats 64 cores!!!)

Erm...
What exactly are they comparing there?
Desktop, server or workstation benchmarks?
With the IMC, even Barcelona can be 60% faster clock-for-clock than a Harpertown in certain workstation benches.

Why do you assume Intel are aiming their 8 threaded CPU at the desktop market?
Not 14 -1 point , game on both PC and consoles -3 points , can maintain and assemble a PC +2 points , so simple math dictates that I am Uber.
Agreed tho buying a Nehalem for gaming is a criminal offense , and just plain silly BTW.

In that case Intel's assumption is right though - the general public (well, at least the ones that buy into that marketing pitch) are indeed morons
Anyone that shells out $1k+ for a QX9650 or even more for a QX9770 is indeed an absolute moron.

Once again, don't be so naive. Nvidia aren't playing dead! Understand economics before you make such a ridiculous comment! Nvidia aren't waiting for ATi or Intel, their shareholders would go ballistic if they were preventing them (the shareholders) from making money. Nvidia are falling in share prices (as is the rest of the tech market, in general) because the US is currently heading for recession. As TGGA said on other thread (where he agreed with me), If Nvidia could sell a $600 card, they would be. Profits are only going to fall this year (I think, but it's not an uncommon opinion) as people are going to be stung by mortgage payments/car finance and any other outstanding finance.

Pretty much the same comments to you as I said to the other poster. Intel aren't holding back 45nm quads, they're having problems somewhere even if tehy don't admit it. Lets look at it subjectively, 45nm ahs been signed off for a while and production is in process, so the millions of $ (if not a billion or more) that have been spent on development for the 45nm CPU's is currently going to waste while they wait for AMD to release faster Phenoms...??
Not in a year of sundays! Intel need to make money off those CPU's to recover the vast investment for their development. No way are they going to sit on a fully-developed product (while it is becoming an obsolete asset) to let their competitors catch up... Basic economics!
Anyhow, onto the OP's question. Personally I think Intel will (and are) struggling with implementation of the all new IMC, native quad & octo and HT Link on a new architecture. It's a big thing to do on a new process and there is a lot that could go wrong. Anyone heard of the AMD Phenom, what problems did that go through, considering AMD already had HT & IMC nailed from K8, they stumbled into a lot of problems with native quad. I am in no way saying that Intel are going to fail, more that I think they're claims over performance are a little premature. If they can implement all those new features on a new process then all the credit to them, I can't help but think they've bitten off a lot in one go with Nehalem!

Just be aware it will fry at some stage - and sooner than you'd expect.
It is my opinion that Nehalem does not exist yet. Therefore, it is too early to form much of an opinion. The Phenom looked GREAT on paper, it looked like a real Core2-killer, but we all know the results of the end product.

With regards to the lifespan of the CPU's... They are retail boxed CPU's, built my a custom PC company, covered by their 3-year warranty. If they went bang tomorrow, I couldn't give two ****! I'd get a new box within the week, so it isn't my problem!

I cant believe Ive read thru this whole thing and havnt seen the obvious question. Like many an Intel fan has rubbed it in the face of AMD fans, you have to buy the more expensive ram, better timings with your IMC based cpu. Wont that also hold true for Nehalem?

I think that his point is that to get everything out of the IMC, you'll need faster (DDR3) RAM. There was a post a bit back as well about motherboards, and also remember that you'll probably need a new motherboard (one that doesn't exist as of yet) to get everything out of Nehalem.

This is true with any CPU. Even with AMDs. In order to truly take advantage of Phenoms features you need a AM2+ mobo. In order to not bottleneck the CPU with older technologies you need the latest mobo and chipset.
Its a universal system and that goes for current Intel Core2 parts as well. A X38 chipset supports up to 4 PCIe 2.0 x16 lanes where as a P35 will only support one.
This is just the way it is.

For the first time as long as I have been alive hardware is outdoing software for the general populous. I remember buying my first dual Pentium 2 workstation for over $10,000, then I bought a dual p3 etc and now finally a quad setup. Design software has always embraced multi threading and now with dual cores at the bottom end of the consumer market and dual quad's at the higher end software vendors will HAVE to embrace multiple cores whole heartedly, or die a slow death. As far as 8 cores go on one die, I don't think we'll see these anytime soon according to Glenn Hilton, here he talks about the 4 core Nehalem with 731m transistors, which is 79m transistors short of the QX9650, so are we really going somewhere substantial, or for day trip to the beach? I think the real developments post 8 core Nehalem's will be chipset management and ram approaching 4Mhz.

1) Nehalem will be a big and disappointing paper launch in late September, October 2008
2) Working processors will be available to OEM in December 2008. GO DELL GO!
3) The first available processors to OEM's will be server MP using the Xeon branding.
4) The first available processors to consumers will be an Extreme Edition in January 2009 using Core 3 branding. Retail price between $1500 to $1800. Quad core at 3.2GHz.
5) The second available processors to consumers will be in March 2009 with mass availablity by June 2009 with quad core architecture without HT enabled using Core 3 Quad branding. Retail price starting at $499 for a 2.8GHz processor.
6) Windows 7 will be late. No way will Microsoft be ready for a Q4 2009 release. Intel will hold back on Nehalem higher clocked processors and Nehalem HT enabled processors will be delayed until Microsoft releases Windows 7 which we'll be lucky to see hit the consumer market in early 2011.
7) Nehalem will overclock poorly because of its new architecture. The processors built using the 32nm die shrink with the revised hyper-threading technology enabled will crash Windows 7 when the cpu is overclocked.
8) Intel doesn't give a crap about AMD today. They did give a crap about the green machine in 2000 when the one GHz clock race was on. Intel doesn't care what AMD put's out in the future because AMD is the little engine that couldn't.

To the folks that say Nehalem will be trash for gaming/any gamer that wants a nehalem is a fool....
YOU ARE THE FOOL.
Either you simpley dont understand or believe what Intel has said about this arch. It has been said that it will be a vast improvement over core2. The same kind of jump we saw from the p4s to core2. Or even more. Im dont feel like looking it up, even more so for folks that have been posting pure bullcrap in this thread.
Its not about how many fricking cores a cpu has. Its not about how many Ghz it can be clocked it. It is all about the performance clock per clock. You people are making it out to be just a core2 quad with hyperthreading. IT IS A NEW ARCH. A Nehalem quad @ 2ghz MAY able to crush all the crush all in the current quads AND DUALS in anything. If it destroys core2 clock for clock and can clock anywhere near the current clock speeds, it will simply wipe the floor with it in everything, INCLUDING GAMES. If its alot faster clock for clock then core2 then it will simply destroy them. It will be the best gaming cpu period,
I think many of you are thinking nehelam is going to do the same thing AMD did. Release there next cpu gen that does perform a couple hundred mhz better then the old cpu. But doesnt clock as high to make up the difference. What Intel has been saying is it will be much better then the last gen. If you believe that is the key. AMD preached the same thing and looked what happened.

Many of us just aren't willing to take anything Intel says as gospel. I for one clearly remember a couple of years ago when the Prescott P4's were being hyped as being a huge improvement over the Northwood P4's. When the Prescotts finally came out the change increase in performance over Northwood was minimal. After all the hype the first Prescotts were just a more expensive processor that required a new motherboard and more expensive memory and offered no real gain in performance.
Hype does not necessarily equal success for either Intel or AMD.
That is fine. I have a wait and see approach myself. I am just addressing a good deal of the utter crap in the thread

With any new socket design and technology you want to wait a few months before bothering. I would definitely recommend waiting until there's a refresh on this new socket design. I believe it's called socket H.

I know 64 is not a lot in the grand scheme of things - I use a 320 node itanium cluster on a daily basis.
But, believe me, in one blade 64 cores is ALOT.
Oh, and there is no discrete cluster in the world with anything like a million CPUs.
I doubt even Folding@Home has a million cores on the go.

What I'd like to see, in the future, from both AMD and Intel, is dynamic clocking on the fly, where the application tells the CPU how many cores it needs and at what clock, and the multicore CPU responds accordingly.
One problem I could see is when clocks ramps down on their own because they're not being used. I'm still trying to figure out if I have a hampered 3870x2 because both CCC and GPU-Z see one GPU @ 421 with a core clock of 421 and the second GPU @ 421 with a core clock of 850. I guess I could lug another monitor over and set it up so I can see GPU-Z while running 3DMark 06, The Witcher or LOTR Online.
I can see the posts from people later on that their quad or octa core is acting funny, with some cores clocked at 2.0 and others at 2.8 or 3.0. I think we'll need a whole generation of new monitoring software just to make sense of it; identifying a core that's stuck underclocked that might mean a CPU is defective.
At any rate, the thing that will hurt Deneb is hyperthreading. Without the advantages of AMD's hypertransport over a fsb, the extra virtual cores will mean that Nehalem will do 3DMark better than Deneb and perhaps game demo's and benchmarks optimized for more cores. Hyperthreading will probably only appear on the EE models, but it has an affect on branding the lower end CPU's in the public's eye.
Considering the switch to a new socket, I might try a Deneb on a trusty AM2 board that supports it over either AM3 or a $250 Nehalem without hyperthreading on an overpriced new socket.
I work in a data center, but what matters to me when I buy a CPU is how it performs at home, not how it does in a server. Unless I actually built a graphics workstation for my wife, I need a good general home CPU that can do everything I throw at it, even if a bit slower than the top gaming rigs people here have, and I sometimes run other applications in the background when I game.
