Quad cores will come first for Sandy Bridge laptops

If you’ve been paying attention over the past year or so, you might remember that Intel released quad-core Nehalem-derived mobile CPUs before their dual-core siblings. Those only followed in early 2010 after the shrink to 32 nm. Intel’s next-gen Sandy Bridge processors will be 32-nm parts from the start, but according to CNet News, the chipmaker is nevertheless planning a similar two-stage rollout, with quad-core parts to hit stores first.

The site says Intel revealed at a "recent investor conference" that the quad-core mobile Sandy Bridge part will launch at the Consumer Electronics Show on January 5, while "more mainstream" dual-core parts will follow at a later date. A less-official industry source elaborated on the latter point, telling CNet News the mobile dual-core Sandy Bridge chips are due in mid-February—and that Intel is forbidding PC makers from discussing them publicly.

Now, keep in mind that the chips coming in January will be Intel’s first 32-nm quad-core mobile parts. Most likely, power efficiency will be better than with Clarksfield, Intel’s current quad-core design for notebooks, which is still fabbed on a 45-nm process. I’m not holding my breath for quad-core Sandy Bridge notebooks with the same kind of battery life and form factors as today’s Core i3 and Core i5 laptops, though.

    Quad core makes much more sense with SB as you get the dual benefit of 32nm and the integrated graphics means switchable graphics is an option.
    Add in any performance gains from the new architecture and if they price it aggressively I can see quad core becoming much more mainstream with this generation.
    Finally a mobile platform with a low idle power consumption giving decent battery life with the option for the discrete graphics or extra cores to kick in when needed.

    Will SB desktop boards support switchable graphics?

    Somehow, I read “recent investor conference” as “recent infestor conference”. Must. Stop. Playing. Starcraft.

    It’ll probably be even later for the LV and ULV versions as well. Intel could take the entire first half of 2011 to completely role out SB mobile units.

      Yeah, and then they’ll just be getting started with the fancier version, which will undoubtedly take another 6 months or so. The people who thought Ivy Bridge was coming in a few months are off their rockers.

      Oh look, it’s MadMan ignoring that the Core i3s are already 32nm and have worse battery life than Core 2s. :p

        Yep, he walked right into that one. 😀

        do the i3’s and i5’s really have worse power draw/battery life if you count the core2 and the external gpu/northbridge together? or do you mean i3 and i5 laptops in general have worse battery life than core2 laptops?

        Can you show us any evidence for your claim ?

          Dunno about empirical evidence, but I’ve yet to see an i3 get anywhere near the battery life of my 1810TZ, regardless of form factor; a friend bought the 1830TZ on the basis of my laptop but has failed to get more than six hours out of it. I can browse the web for a solid eight and a half hours on it now I’ve chucked an SSD in it. The C2D CULV systems just seem to suck a lot less juice on the whole.

        Look, it’s OAS being a dumbass and ignoring the fact that the Clarkdales have a 45nm northbridge and are not monolithic. (Yes, I knew the CPU of a Clarkdale is 32nm.) Also I clearly pointed toward the example of a 32nm monolithic CPU versus a generally equivalent 45nm CPU where the former -[http://www.techreport.com/articles.x/18581/4<]§ compare the i7-975 versus the i7-980. Now consider what will happen when the number of execution units is the same with a die shrink rather than 1.5 times greater...hmm.

      But you are slow, i saw this news their since one hour and no was bothered to even comment…

        Ditto. I saw it too and was betting on Jigar snatching it up.

          Really ? Why do you forget that i promised you that i won’t comment like this anymore, since you have been baby crying in front of me to get that chance …
