ok i noticed how hp has a quad core in a laptop. now i am going to buy a new laptop next summer only thing i am not sure about is the processor. now i dont know much about quad core. i know they are fast a good. should i get a quad core. and are the quad cores for laptops true quads or non true quad core (i think the non true quad cores are call core 2 quad). i was really interisted in a true quad core. or should i just get core 2 duo with 2.9ghz or something. i also want long battery life and good performance. so i dont really know if the quad cores suck battry life. any help would be great.

They are "true" quad cores. They use more power so less battery life. A higher clocked dual core will perform better if the application is not quad threaded.

The ones out now are, I believe, on 2 dies (although I could be mistaken), so they're not "native" quads. However, the quads that will be out next summer will be native quads. The new quads will also be optimized for battery life, so notebooks containing them will likely last somewhere between as long as they do on current mobile Core 2 Duo CPUs and current mobile Core 2 Quad CPUs.

Djembe you got me. To OP the current mobile quads are as true as the first desktop quads. But with the release of the I7's which are what one might call "true" are 4 on core vs 2+2. And yes they should be out in Q3 of this year you will still use more power than dual I suspect.

can you tell me how you know about the quads comming out next year? and what kind of duo cores are comming next summer? i talked to a guy on another website and told me i was better of staying with duo and he convinced me. i was compairing the core 2 quad intel Q9300 2.53ghz 1066mhz or the intel core 2 duo T9800 2.93 ghz 1066mhz and since both are the best quad core and duo cores there is on laptops right now he said the T9800 is the way to go. i would like to look into these quads that are comming out next summer.

Actually they next quads are coming out this fall or winter, and the next dual-cores are coming out in January. The quads are clocked pretty low (1.6-2 Ghz) but are based on a newer architecture (called Nehalem), which makes them noticeably more powerful than current mobile CPUs running at the same speeds. However, they may or may not be as powerful as the significantly higher-clocked current mobile CPU offerings. Nobody knows yet how the new dual-core mobile CPUs will be clocked, but they will also be based on the Nehalem architecture.

Intel's plan after that is hazy, but there has been some speculation that toward the end of 2010, they will launch mobile quads based on the Sandy Bridge architecture, which incorporates all of the Nehalem features and adds better automatic demand-based core overclocking and better power management. However, chances are that the Sandy Bridge processors won't yet be released by next summer.

edit: AMD also plans to release mobile quad-core processors next year, although precisely when and what clock speed the processors will run at are mysteries.

QX9300 2.53Ghz can be OC'd to about 3.0Ghz The fastest C2D is the X9100 3.06Ghz can OC to about 3.53Ghz and the T9900 is 3.06Ghz.

The new Quads I7 mobile (Calpella platform) Nehalem microarchitecture (codenamed Gilo) might come out Q3 or Q4 of this year. Intel for the last several years has aimed to offer new platforms in Q3. This year is a major one as no longer Core technology. That is kind of how many know. Intel releases info and has a known schedule for product introduction. Because of the major change in this years release looks like they are a little behind.

Don't look ahead to next summers releases as this summers are not even out yet. And there is already a notebook out with a single die Quad I7. Yes it is a desktop CPU but well just wanted to throw that in.

The person on the other site likely feels that higher clocked dual is better than lower clocked quad because quad threaded applications are not yet the norm. As such on a single or dual threaded application a faster dual will out perform a lower clocked quad.

Calpella has lower clocks than current C2Qs.
