I was under the impression that the mobile i7 uses DMI instead of QPI. Am I wrong?

QUOTE(astria @ Nov 2 2009, 04:43 PM) problem with mobile quad is that they consume another 10W more than the dual cores... On the flip-side, I doubt anyone getting a quad core in their notebook is thinking about mobility in the first place.considering the amount of heatsink needed for cooling and battery life, it's not really mobile friendly... imho, dual core will still make up the majority for at least 1 more yr when comes to laptops...  |

QUOTE(crazycyp @ Nov 26 2009, 06:03 AM) core i7 is 4core can run 8 treads ....... where got 8 core ??? It isn't wrong, per se. The Clarksfield line of CPUs all have four physical cores and with Hyper Threading enabled, it gives them a total of eight logical cores. So, what Mr.Docter said is right, technically speaking. |

QUOTE(KimRoss @ Nov 26 2009, 11:49 PM) Refering to the autocad question, seriously i7 for autocad? not necessary. c2d is more than sufficient. unless you're talking 3d rendering, that's abit different In that case i7 isn't necessary for a whole host of functions. C2D can run 'em all. It is just a matter of how fast your work will get done. On a more positive note, I've finally had the chance to see Clarksfield in action first hand. It does wonders for AutoCAD, C#, C++, you name it, it does it.  QUOTE(putochip123 @ Nov 27 2009, 12:32 AM) YUP, U R RIGHT, EVEN PLAY War craft also lag. Warcraft as in Warcraft III and its TFT expansion, or WoW? Because I've run TFT on a Celeron, no problem.This post has been edited by Loki[D.d.G]: Nov 27 2009, 02:11 AM |

Interesting preliminary prices have emerged for three Arrandale processors. Fudzilla has the details.

QUOTE(outlife11 @ Dec 2 2009, 12:12 PM) ic... is that mean i can take full control of 4 core ? You cant equate a processor's clockspeed like that. If you could, a OCed i7 920 at 4.0GHz will have an effective clockspeed of 16GHz on one core if use 2 core = 2.8Ghz/2 = roughly 1.4Ghz per core ?  VBy the way, I posted an answer to your original question before; QUOTE(LokiD.d.G @ Nov 30 2009, 05:36 PM) Actually different Clarksfield processor Turbo Boost differently. The i7 720QM has a Turbo Boost ratio of 1/1/6/9 meaning that when all four cores are being utilized, it'll increase its multiplier by one, giving you a clockspeed of 1.73GHz. When three cores are being utilized you will get a similar result. When two are used, it will boost its multiplier by six, giving you a clockspeed of 2.4GHz. And when only a single core is needed (which is rare nowadays) you get a clockspeed of 2.8GHz. In other words, 133.33MHz x 21 = 2.8GHz. The i7 820QM has a Turbo ratio of 2/2/8/10 and the i7 920XM, 2/2/8/9. On paper this seems very promising, but due to feedback on their real world performance, one can assume that somehow the Turbo Boost function isn't working the way it should. |

QUOTE(ian90 @ Dec 25 2009, 09:37 PM) hm.. people, do u think i should wait for arrandale chips or just buy a laptop with c2d P8700? i wonder if the price is in the same range... since the i5 specs are not that far off from the P8700 Never compare two processors based on different architectures clock for clock. Chances are, Arrandale is going to run circles round current C2D processors when it is finally released. And according to Intel, that eagerly awaited debut will be during CES 2010 |

Dell has finally released the expected plethora of notebooks with an Arrandale refresh.
Laptops with the i5 treatment include the Studio 15, Studio 14 and Studio XPS 16 Though each costs substantially more than their individual base package. This post has been edited by Loki[D.d.G]: Jan 8 2010, 04:44 AM |

QUOTE(leymahn @ Jan 13 2010, 01:00 PM) if i get a new laptop, is it worth to wait for the i5 considering that only dell offers laptpo with i5 processor nowadays? Clock for clock, the new Arrandale processors are absolutely decimating their older Penryn counterparts.performance wise, is there any major difference between i5 and c2d? So, perhaps it would be worth waiting for more manufacturers to bring in their i5 equipped rigs. Hopefully with ATI's latest Mobility Radeon HD5000 series included.

QUOTE(synz @ Jan 14 2010, 01:24 PM) afaik, acer has 5740G with i5 520M and HD5470 (rm2999) or i5 430M and HD5650. either u take better processor or gpu RM3k for the i5-430M and HD5650 sounds too good to be true. It's akin to the BenQ S57, and that is an EOL model, not brand spanking new. And considering this comes with Windows pre-installed, if true, it is probably the deal of the year; And it's only January This post has been edited by Loki[D.d.G]: Jan 14 2010, 03:45 PM |

QUOTE(synz @ Jan 14 2010, 05:08 PM) for ati5650 im not sure.. thats y din put the price there. definitely will be higher but by how much? no idea. if 200 or 300 extra still acceptable to me but is that possible? Consider that comparable notebooks with the HD4650 cost RM3k and above. Then consider Arrandale is new tech, as is the HD5000 series.the price for 4740G is now rm2500. with i5 430M but only 2gb ram and 14" display. lets say add another 2 gb ram, larger screen and ATI 5650-Geforce 310M. can it goes up to 3.5k? RM3.5k is a conservative guess, IMO |
