    Finally Qualcomm has stopped chasing a high core count. Snapdragon 820 announced with a quad core chip and up to 2.2Ghz. Why did the A9 perform so well despite having so few cores? Because be underlying chipset architecture was better. Thankfully Qualcomm has realised that as well.

    I've given up on HTC I think:/ my next phone after this iPhone 6 might be the next Nexus,next motorola, next Samsung(rooted and flashed with a AOSP ROM of course) or an LG phone. Hell, I might even pick up the updated version of the Priv!

    The M9 was just a regression in every way...

    I wouldn't mind a Nexus 5" phone (as in 5.3-5.7" display)
    4k resolution (Needed for VR viewing of video and gameplay)
    Fingerprint reader and password access in the Play Store a la Apple App store
    SD 820
    3-4gb of ROM
    32GB of storage (minimum)
    3500mah battery

    Not really stopped chasing high core count. This bad boy has a 6 core dsp processor and another isp dedicated core for images along with a beast of a gpu that has at least 8 cores in it.

    I'm talking about CPU core counts. Chasing those for marketing purposes was stupid, these modifications however are much better.

    What an awful click-bait thread title. I hope the moderators come and fix it.

    Agreed. And "core count for marketing"? No one gives a crap.

    I'll wait for the next Exynos from Samsung.

    I think MediaTek have surpassed Qualcomm with value and I hated MT for years. Qualcomm already started burning their bridge with the 810. I hope they can return to the quality of their 800/801/805.

    The key here is if all the SoC makers step up their game. The only numbers that really matter to anyone is the price. I don't want to see Qualcomm dominate the SoC market and price gouge the customers with their flagship chips. If no monopoly, everyone can win. I would rather see Qualcomm go down just to watch the field even out. If Qualcomm goes down, prices go down. Like an Snapdragon 820 is really going to matter to most consumers who checks their email and social media all day? In two years, it will start to LAG. You know, like in ANY phone with ANY OS and ANY SoC.

    All these specs being thrown at us is just brainwashing us into the hype. Instead of fantasy sports, it is stats for geeks to crunch and benchmark with gadgets. Wash, rinse, repeat. Remember how amazing Snapdragon 800-801 were? Two years later, they still are! Except the software updates is making them laggy. I'm waiting on Samsung. At least they can be truly independent if they want to. While other brands need to rely on Qualcomm to succeed.

    FFS.

    Do you understand the fact that the high core chips only have 2 or 4 high performance cores with the other 4 being low performance.

    It's never been about core count, but rather a balance of power and efficiency. Also, due to ARM making the big.LITTLE architecture available, it was cheaper and faster for chip makers to go with Hexa Core or Octa Core.

    Qualcomm must have found a way to build a quad core that is both powerful and efficient, take note that they had to speed up development of the 820 as they took a shortcut with the 810 by going with ARM's architecture, that should be a clear indication to you of why Hexa Core and Octa Core have been popular.

    I am guessing that the Kyro cores are also going to use "hot plugging" (I think that's what it was called), and this may either make them snappier than Octa Core or lag a bit behind especially when comparing to how far Samsung have come with Exynos and its excellent Octa Core implementation.

    Yes I think I DO understand that the big.LITTLE architecture was used for that however I've observed everywhere people touting "WHOA!!! MOAR COREZ!!!!" as if its a good thing. It was about balancing performance and efficiency but they could have done it without using bL like how Apple did.

    Yeah, I am also well aware that the 810 was a stop gap as they had to recover from the fact that the A7 was 64 bit (this is the correct time frame, right?) and they didn't have the time to design their own custom SOC in time.

    I think they see the writing on the wall, Apple with its fantastic speed on the A9. Companies opting for other makers because Qualcomm's chips get too hot and/or not that fast.

    Yes but the task manager will push processes to the dsp cores to offset the BIG power hungry cores.

    And just thinking about it I don't think I've ever seen Samsung or any other company market 8 cores.Samsung used quad cores and 8 cores on the same model phone in different markets and they knew well not to brag or talk much about there 8 core version phones.

    And why are you saying the a9 is a better architecture? Because it has higher ipc on single core? Last time I checked more cores when pushed all at once can dominate the a9 and that's last years 8 core designs.

    Apple went fat cores for max instructions per clock at the cost of not being able to clock them as fast as other designs.

    Sammy and Qualcomm went smaller cores that can make ground with higher clocks and higher core counts.

    Android has no problem using all 8 cores and spreads its tasks across all the cores efficiently. Comparing apple single core performance is like putting a v8 on a dyno and then unplugging 4 spark plugs and seeing how much power the car puts down.

    In multi threads the 8 cores chips still dominate

    Here is the full potential of a note 5 with Samsung's full speed bins unlocked and running at 2.4ghz.I broke 6500 geekbench lol

    If the rumors are true, Google is likely planning to create an OS/Hardware pairing for future Nexus devices to match the current iPhone arrangement. I would expect the theoretical chip in those devices to be more conservative in design however significantly more efficient.

    Yup, I saw that, and don't forget Samsung basically doing the same thing. The writing is on the wall for Qaulcomm and I think realize that the status quo will not work

    Lol. Keep getting those high geekbench, numbers, we'll keep enjoying our phones with "¼ the specs" that are still faster.

    Still faster? Lol sure bud if you say so.BTW my note 5 hits well over 550mb nand read speeds almost double what this baised anandtech review shows.

    Samsung's memory in the exynos 7420 is still the fastest out and I have no idea how annand got such low numbers

    What's the point when samsung's/lollipop's ram management is so poor it can only hold a few apps in memory with 4gb of ram?

    And why are you mentioning memory speeds? You sound insecure.

    There's your problem, its not the makers that say woah more cores, its reviewers and people who don't understand.

    Lets wait and see if Qualcomm have truly done a good job. If they still use hot plugging then the 820 may fall behind to the big.LITTLE Exynos 8890

    Show pics or it didn't happen. Samsung doesn't use NVME and I can't believe you for a second.

    Face it, 2015 was not good for Android SOCs. I expect big things from the 820 and the M1 which is Sammy's custom chip (I believe)

    The Exynos 7420 was a great SoC, the new Huawei Kirin 950 seems to be very good to, the Snapdragon 808 has been great in the LGs and Motos that use it and MediaTek continued to improve vastly.

    You are literally taking the downfall of ONE SoC (Snapdragon 810) and painting the other SoCs the same just because the ONE was poor.

    Sorry I meant that many flagships were let down by the 810! I worded it incorrectly, the Exynos chip was pretty great.

    If CPU performance keeps doubling year over year, how long do you think it'll take for SMT to make an appearance on mobile CPUs? I mean it looks like the front end is getting insanely quick at executing instructions...
