Why is there no 6-core processors for laptops yet ?

    Since there is already dual core i7, with base clock of 2.6ghz plus iGPU, and under 15w TDP.

    6600U, 2.6ghz, turbo 3.4ghz.

    It should be possible to put 3 of those chips and the TDP becomes 45w,
    why that haven't happened yet ?

    Tdp limitation maybe.

    I'm guessing the math wouldn't be that simple. I'm sure it is possible, but it's difficult and there probably isn't much of a market for it. If you really want a hex core processor in your notebook computer, there are some Clevos that use desktop processors and you could put a hex core in them.

    We'd be stuck with 2Ghz chips. Good for parallel computing, which won't affect enough apps for general consumers to justify the move.

    Turbo boost would make this a non issue.

    easy: look at intel's development strategy in the past few years!

    weve seen an increase in igpu performance of ~850% going from sandy bridge to skylake, which opposes an actual cpu IPC performance gain of 28% (over four friggin generations!!!) look at die shots of current cpu gens, the igpu takes up MORE THAN 50% of the total die area in a cpu! thats insane!!!!

    intel needs to get their head out of their ass and start focussing on its actual product again, namely cpu performance! no matter how fast igpus have gotten, they still absolutely and abysmally SUCK compared to proper dgpus. so please intel, just include a simple igpu for desktop day to day operations, browsing and video playback (smartphone gpu is enough for that, basically) and get rid of those unecessary extra igpu transistors to make more space for additional or more performant cpu cores!

    reasoning: if intel chose to release mainstream cpus with more cores then the software engineers for popular software would follow suit and optimize their tools for parallel computing!

    theres absolutely NO excuse whatsoever to not have 8-10 core cpus in laptops nowadays!!!

    I believe your reasoning is flawed. Intel does not control the software market; they are simply a part of it. If Intel took the "build it and they will come" mentality to heart and made lots of octa-core notebook processors under the belief that doing so would cause software developers to rewrite their programs to be more multithreaded, then they (Intel) would have to deal with a huge backlash of dissatisfied customers whose highly expensive 8-core processors don't work any faster than 4-core processors in existing programs. And that backlash would continue for at least 2-3 years until software caught up. Intel would not risk the poor public opinion and resulting loss in profits that would result from such a scenario.

    Instead, they wait for existing software developers to come to them and say what they're looking for. And thus, Intel can then design around existing software and make minor incremental changes while still maintaining profit levels.

    This is in the context of wattage. TB really has not much to do with it. Unless you want to pay big money for 28 seconds of 600 more Mhz.

    - Why would there be?
    - Low TDP 15W chips can draw *FAR* more than 15W. They get limited under heavy load, quite easily usually. There is a reason that the quadcore chips had far higher TDP, and even then could be TDP limited
    - As said above, you'd be limited to a slow speed like 2GHz. Turbo boost is pointless if the chip gets close to touching its TDP, and you're not running say a six-core 3GHz+ CPU at 45W doing heavy CPU loads where the extra cores would matter (since most loads are single or dual-threaded, and even properly quad-threaded or higher loads are hard to find, far less the 12 cores that'd have).
    - Next, there is no way somebody is soldering a 6-core, 12-thread CPU onto crappy mainstream laptop boards by the thousands
    - HEAT
    - Mainstream desktop boards don't even have above 4 cores/8 threads... you want mainstream, especially low power, laptop CPUs to hit 6c/12t? It won't happen for a long time
    - Intel doesn't care about high performance computing in notebooks. Desktops would get it first, easily.
    - Intel isn't even pushing computing performance with each generation these days in desktops. As Jaybee said, their per-clock performance has stagnated since sandy bridge for the most part. Cache, RAM, chipset, etc may have gotten better, but no way has the core been pushed greatly. iGPU and chipset are getting all the benefits, with heat barely being considered.

    i dont think i need to tell you that they already have 6 cores in desktops, first one even in 2011. I agree with the rest of what you said tho.

    No reason to compromise single core preformance if you cant get more multi core preformance back for it.
