    Interesting choice with the 2+2 CPU config. I'm excited for this chip!

    Oooohhh looks like someone followed up on the ideal configuration of 2 LP + 2 HP configuration...

    2x efficiency would mean 2x perf at same power as S810 but they can't push it that far on the power side again. They compensate a bit for this with just 2 cores clocked high but , in the end, the 2x perf claim doesn't fit the math. So i guess maybe we get 25% over Exynos 7420. No benchmarks again so something is off there.

    New Geekbench high score for SD820 http://browser.primatelabs.com/geekbench3/compare/...

    Doesn't look impressive vs A72 at 2.4-2.5Ghz in integer and FP if the score is close to what it will be in shipping products but not bad either.The memory score is very high, assuming 128 bit bus but remains to be seen what Mediatek does with the X30 on the memory side and ofc Exynos 8890.
    The multi-core score better not be final, it would mean it gets rather hot pretty fast.
    Speaking of the 8890, the 30% CPU perf gain claim might not be great but T880MP12 should beat SD820 easily.

    Interesting to see someone else go the HMP route, I put this question to one of their peeps on twitter just yesterday.

    Does the fact that an L3 is present preclude it from being based on ARM CCI-X00, I thought the CCI could utilise an L3$?
  • Andrei Frumusanu - Tuesday, November 10, 2015 - link

    There is no CCI with L3 so likely this is just a tightly coupled design with coherency being handled by the L3.

    That was my assumption as well. I like this idea and am curious to see what perf/latency and energy usage looks like switching from cluster to cluster on S820 compared to those that use big.LITTLE.

    Its a return of the king: THE KING OF QUAD-CORE CHIPSETS!
  • skavi - Thursday, November 12, 2015 - link

    Hopefully the king of all ARM chips. I don't want another Exynos making custom OS's difficult on the S7.

    What ? No review ?

    :-p
  • iwod - Wednesday, November 11, 2015 - link

    15% Efficiency improvement should close the gap between Wi-Fi. That to me a a very bold claim.
    What was the Efficiency compared to? Previous Gen ( 9635 or 9645 ? )
  • MrSpadge - Wednesday, November 11, 2015 - link

    It is a strange claim in the way that it shoul be easier to transfer data at the same rage over a few meters than over a few kilometers. If both perform the same, the WLAN needs efficiency tuning.
  • Le Geek - Wednesday, November 11, 2015 - link

    The first graph needs to be taken with a grain of salt. There is no way the snapdragon 810 consumes less power than the 801 or even the 805
  • MrSpadge - Wednesday, November 11, 2015 - link

    That's probably average power including idle time. That's what "real life usage" usually means. Race to idle helps a lot in such cases.
  • Le Geek - Wednesday, November 11, 2015 - link

    Well in that case, why is it that phones this generation are consistently getting worse battery life than their previous generation counterparts running 801/805 socs. See the battery results for Oneplus One vs Oneplus 2, HTC One M8 vs M9, Xperia Z3+/Z4 vs Z2/Z3Z3, well I could go on and on.

    It seems that even after you account for race to idle, the 810 ends up consuming significantly more energy (not necessarily power) for a certain task.
    The fact that 810 overheats like anything only seems to substantiate these claims. Since the SOC does not do any mechanical work, all the power consumed ends up as heat output.
  • Drumsticks - Wednesday, November 11, 2015 - link

    Well I don't know about the others, but a big drainer for the M9 is the lack of static display refresh or whatever it's called.

    Although anecdotally, I'm not convinced there's much of a difference either way. Which makes sense given they barely have a difference in the charts. I'm sure the 810 is 3% more efficient than the 805 in some contrived scenario.
  • 0razor1 - Tuesday, November 17, 2015 - link

    PSR: Panel Self Refresh is all I know that is the same as you mention 'static display refresh' ?
    The zenfone 2 also has this issue and eats through 3k mAh thus, :)
  • Gigaplex - Wednesday, November 11, 2015 - link

    Screen resolution increases also eat a chunk of battery.
  • menting - Wednesday, November 11, 2015 - link

    "consumes less power" most likely means the amount of energy it takes to do the same work (else you can't compare between them), which will make their statement true.
  • Le Geek - Wednesday, November 11, 2015 - link

    But that surely does not explain why devices with 810s have significantly less battery life than their predecessors running 801/805s.
  • BillyONeal - Wednesday, November 11, 2015 - link

    Most of the devices with 810s also had either smaller batteries, higher resolution screens, and/or more bloatware installed.
  • Shadowmaster625 - Wednesday, November 11, 2015 - link

    Devices have less battery life because people are buying devices that have less battery life.
  • sseemaku - Thursday, November 12, 2015 - link

    Exactly what i was thinking! How will anybody believe that chart after what SD810 has been in phones!
  • SydneyBlue120d - Wednesday, November 11, 2015 - link

    Can You confirm unlimited HEVC 2160p60 with both IOS and HDR enabed encoding support? 8 bit or 10 bit color? Thanks a lot.
  • Zack123 - Wednesday, November 11, 2015 - link

    The last batch of Snapdragon chips had issues pushing their full cores for long periods. I hope, more than almost anything else, that issue has been resolved.
    Also, since all the other chip makers (starting with Mediatek), seem to be stating some random and absolutely off the cuff specs, Snapdragon is unfortunately the only (apparently) reliable processor company right now.
    I hope this is as good if not better than the Kirin 950 and others in longer term processes and gaming.
    The last few years have seen spme strange kinds of stagnation.
  • bushgreen - Thursday, November 12, 2015 - link

    So does this use all 4 cores at the same time or just 2 at a time?
