Qualcomm asserts eight-core mobile processors are 'dumb'

  1. Qualcomm has joined the likes of Nokia and Intel in raining on the proverbial multi-core processor parade. During a recent chat with Taiwan media, Qualcomm senior vice president Anand Chandrasekher said eight-core processors like the new chips recently announced are...

    Lol really a good modem

    8 cores are rather overkill...I dont think 4 cores are, though, when it comes to more professional devices...

    Hmm maybe they don't have a 8 core?

    Good for you Qualcomm. Don't pull a 180 on us please.

    The issues with the other cores beyond 2-cores is most of the software is geared for 1-core. Second core was good to you could do more things at the same time. I own 1, 2, 4 cords it's okay. But 8 cores would be overkill since nothing really going to use the extra cores.

    8 core CPUs are dumb for mobile devices. We dont even have many consumer 8 core CPUs...

    AMD Opteron 6000 is 16-core.. I don't need so many cores. Smartphone I just have 2 cores now that's all I need.

    Just another marketing gimmick to sell more devices to the mostly dumb masses.

    I would say it is marketed toward the non-technical crowd rather than "dumb".

    I would be happy with 2 cores at 3ghz with 8 gigs of ram...
     
     
  13. I would be three-quarters happy with 3 cores at 2.66GHz, with 6.71 gigs of ram, but no mobo.
     
  14. Now one will ever need more than 640k

    maybe not now, but someday
     
  15. Eight cores is a great way to drain a battery pretty fast. If you can do 50% of what a 8 core can do with just 2 cores and have 50% more batery life, who need that much power on their cell phones?, it is not like you are gonna play crysis on them.

    Another stupid guy claiming another thing as stupid. Well,one day he is going to eat his words just like the other stupids claiming something as dumb. It is just a matter of time when either the hardware itself or the software can very efficiently utilize all cores available and the more, the better. It's just like when some stupid claims that we dont need another os when android was just starting out. Look where android is now.

    This guy has no vision for a greater future.

    Back 20 years ago the power of a supercomputer in a home PC was dumb. But yet you can just about get the same performance out of a cellphone. We are talking 59.7 GFLOPS in a supercomputer of 1993 vs 25 GFLOPS in a Mobile SoC GPU (and the Mobile link is even dated). Can you imagine what everyone thought in 1993, about needing that much power in a hand-held device?

    If he said that 8 cores are "dumb" at this point and time (or generation), then I would agree with him. But without a time constraint, he sounds pretty dumb...

    Mmm it's an interesting argument. Only need 8 core if you can utilise that many threads. Not sure why a phone needs that much firepower either. You'd have to change what smartphone os's do. Advanced video/audio processing in real-time? Who knows..

    Yup. A good-quality modem that minimises power consumption is essential. This is in the top three (if not highest) power guzzling things/apps on your mobile.


    By the way, spreading workload over more cores is beneficial to battery life. 8 cores running at 0.2GHz is better than two cores running at 0.8GHz. More voltage is required for lower-cores at higher frequencies, which means more battery drain.

    Case in point, why was P4 abandoned? Because of high power consumption and temps. Dual-core CPU's demolished P4's on all fronts. Also, you can see Intel is having ~3.5GHz as the highest clocks that the consumer (and even enterprise) CPU's get.

    Low IPC due to pipeline stalls, they aimed for high clock rates rather than increasing IPC * clock speed which is the real goal. Architecture was very inefficient.

    It seems to be easier to increase IPC via better multi-operation (SIMD etc) instructions, branch prediction, addon dedicated operation instruction sets like AES libraries than trying to break down the pipeline into smaller pieces and ramping up clock rate. After all the specialised nature of much of the x86 instruction set is why it beats RISC based processors as you gain a small amount of kludge in your processor but gain massive efficiency or throughput in specific ops (which are obviously tuned to bottlenecks).

    Why are all those people just sitting under the Qualcomm sign in the pic?... Demonstrating their aversion to an eight core processor?

    It is a rare thing for the six cores in my PC to be all working at once, why would I want two more in my phone?


    Human, huh...

    Why cant we use these chips with windows OS? They are extremely efficient? are
    there any hacks or anything for it to work?

    They aren't x86 I thought? They are ARM... your entire Windows app ecosystem wouldn't run on them.
