I don't know anything about this new CPU except that it will use a 1155 socket. Will this new CPU be useless to most people like the 6/8 core CPUs are? Any other information is appreciated.
What is Sandy Bridge from Intel

Imagine an i5/i7 CPU with a slight performance increase, but using less power. That is essentially what Sandy Bridge will be. It will have the features that i5/i7 CPUs had, like hyper threading and turbo, but the architecture and instruction set will make it, in theory, a fair bit quicker than current i5 and i7 CPUs, mainly because it has a new instruction set that apparently makes it better for doing floating-point because it allows 256 bit data paths, rather than 128.
Downside though is no overclocking. The processors are locked so you can only get something like a 2-3% overclock, so at the moment, with boost, the highest announced clock speed will be 3.8GHz, so overclocked 3% would be 3.914GHz
Initially there will only be quad, then later hex and octo core CPUs will be out. Basically what you said is right that they will be useless unless you need a very fast processor, for rendering and code compilation and such. For the every day user and gamer, they are completely pointless, as current processors will handle it perfectly fine. The only upside is that when they come out, hopefully current nahelem processors will go down in price
@fastdude the wiki article is a hell of alot of speculation. Sure that is all you can get because they aren't out, but like most other articles on wikipedia, it doesn't distinguish well between stuff announced from Intel/leaked info, and pure speculation, so to OP, if you use the wiki article, check the citation

OK, will in future. Good explanation:good: pity they're going to limit OC'ing though. Haven't they tied something like every bus (USB, SATA, PCI-e , uncore, ect.) to a single clock generator issuing the basic 100MHz base clock, thats the "locking", isn't it? As you said, only 2-3% via base clock adjustments.
Hopefully 1156 price would have fallen by then, though.

yep, because the BUSes inside the processor can go further, they could be pushed further, but other BUSes, like Sata and USB, are very sensitive, it stops you from going very far at all, because they will get unstable, so it has (reportedly) been locked (that bit is speculation whether it actually has been locked or not afaik)

Even though you can still get 3.8ghz I will refuse to buy just for that. With luck though AMD comes out with a fast chip and get some much needed boosts so they can bring the fight back to Intel.

Bulldozer seems to have everything that sandy bridge has, and more. Only thing missing is hyperthreading, which they rectified buy get 2 physical cores per module, rather than 1 core with 2 virtual cores from it, and on the fly overclocking, which they don't have, because they have overclocking.
They will seem to have the server possition taken too because the server processors will support quad channel memory, as well as having all the features that the normal bulldozers chips will. Deffinately saving for an AM3+ board now so I can slowly merge over to a bulldozer chip because provided they live up to expectations, they have Intel cornered with no way out.
Provided they keep AMD prices and not go to the extautionate levels that Intel do when they bring out a new chip
When I was in college most professors would not accept Wikipedia as a reference for research.
I bet someone will figure out how to over clock SB, or at least spend a lot of time trying.

Bulldozer does NOT have two cores per module, each bulldozer module is technically still a single core, but with multiple FPUs, Two integer cores, and a shared decode/fetch stage. Think of it like hyperthreading...but technologically the opposite of it.Bulldozer seems to have everything that sandy bridge has, and more.

Yeap, AMD is throwing a monkey wrench in what a core is, confusing the hell out of everybody.
They claim it only adds 12% to the die size.
If they come close clock for clock to Sandybridge and market this thing as (my module vs. their core), they could end up with a multi threaded monster.
I wonder if they will set this module up so both sets of pipelines can run the same single thread, if so bonus.
Plus if they dont lock it down so you can overclock, another bonus.

Yes it is an ugrade. Sandy Bridge will be more poewrful and use less power than Nahelem. Apparently they will be still named i5 and i7 though, so bring back the confusion that came about with the P4 processors and how they spread over different sockets and some have different architecture to others
Intel is a company which apparently makes products that rely on logic. If only you americans knew the meaning of irony

lol
Aren't they going to be named some illogical naming scheme like:
i5-2400
i7-2800

Well, my guess is that they won't market it that way. From what I've seen, they're marketing it as 1 module = 2 cores. The more I read about it, the more I think that Bulldozer is only just going to catch up with Nehalem, and that Sandy Bridge is going to be the biggest upgrade. When it comes to overclocking, supposedly the unlocked chips shouldn't be that much more expensive than their locked counterparts. I'm still a bit skeptical of it, though. With or without overclocking, I read at this link about a Sandy Bridge prototype (quad-core), and supposedly it's comparative to the 980x in some scenarios:Yeap, AMD is throwing a monkey wrench in what a core is, confusing the hell out of everybody.

As an added bonus, the integrated graphics is faster than a discrete Radeon HD 5450 since it shares the CPU's L3 cache (it's on-die with Sandy Bridge, rather than off the main die with Westmere)

I thought sandy bridge had 2 sockets? 1155 and 2011, 2011 comes out in Q3 next year. Also, I heard there is still overclocking but only certain cpus.

I think 2011 is the year the socket is coming out?
