After teasing the Exynos 9810 in CES related press material back in early November as well as having early announcement about the new modem capabilities last summer we now finally see the official announcement of the new SoC ahead of CES next week.

The new Exynos 9810 much like the Snapdragon 845 announced a few weeks ago in December, is a major upgrade on the CPU side of things as we do the migration towards a DynamiQ cluster configuration. Here we find Samsung’s third-generation custom core, the Exynos M3. We don’t know much about the micro-architectural changes of the new core, however Samsung has stated that the new CPU has a wider pipeline, and improved cache memory. What we expect is a large overhaul of the memory subsystem in the private L2 cache, as well as a larger L3 which will bring major performance uplifts in memory access during heavy workloads. Coupled with the M3 cores we see ARM’s new A55 little cores used as the efficiency cluster.

Samsung hasn't announced all of the new CPU parameters yet, but they have announced a 2.9 GHz maximum frequency for the M3 cluster, which is a large step up over the 2.3 GHz of the outgoing model. This is thanks to the Exynos 9810 being produced on the second generation 10nm manufacturing node, 10LPP, which promises up to 10% performance increases at isi-power or a 15% decrease in power at iso-performance.

With the increased IPC that is expected from the new cores, and the faster frequency, this should be a significant increase in performance from the outgoing model, which we saw in our comparison test was fairly evenly matched with the Qualcomm Snapdragon 835. Samsung claims up to double the single-thread performance and 40% uplift in multi-thread performance. The single-thread performance claim would be the single biggest performance jump in the industry and if we're even just talking simple GeekBench scores that would put the Exynos 9810 at the performance levels of Apple's A10 and A11. Of course having this on a quad-core CPU begs the question of how it's achieved and if this 2.9GHz clock is on all cores or just a single-core boost clock? And at what kind of TDP does it achieve this massive performance boost?

The GPU follows the lead of the Kirin 970 in adopting the new Mali G72 Heimdall GPU IP from ARM. What stands out here is that Samsung has actually decreased the GPU core count from 20 to 18 while still managing to increase performance through an increase of the clock frequency from 546MHz to a higher undisclosed frequency likely in the mid 700MHz range. The performance increase is conservative at only 20%, but more importantly efficiency should be up thanks to the new GPU and process.

The modem as disclosed earlier in 2017 now adheres to 3GPP Release 13 and implements UE Category 18 up to 1200Mbps in its downlink capabilities through up to 6xCA and 256-QAM, slightly exceeding the capabilities of the Snapdragon 845 and Kirin 970 on paper, but likely something to be tested in practice. The Exynos 9810 modem also is the first one to employ 256-QAM in the uplink and thus achieving up to 200Mbps speeds as a UE Category 18 in the uplink as well.

As is usual with new flagship Exynos announcements the SoC is likely already in mass production and waiting to be used in the new Galaxy S9 series which in turn will be expected in the MWC timeframe at the end of February.

    "there's still a type (isi-power)"

    Please verify if there is L5 location support on par with Broadcom BCM4775X:

    • GPS L1 C/A
    • GLONASS L1
    • BeiDou (BDS) B1
    • QZSS L1
    • Galileo (GAL) E1
    • GPS L5
    • Galileo E5a
    • QZSS L5

    Thanks a lot!

    Afaict brcm is still the only vendor to offer l5 signalling support. Reply

    "The single-thread performance claim would be the single biggest performance jump in the industry and if we're even just talking simple GeekBench scores that would put the Exynos 9810 at the performance levels of Apple's A10 and A11."

    Single-thread performance up 100% and multi-thread performance up only 40% doesn't make sense at all.
    Try it the other way round:
    Single-thread performance up 40% and multi-thread performance up 100%.

    Why would it not make sense? Mobile chips are power limited under all-core load. So if you make the cores twice as fast for e.g. 50% more power (better efficiency), you'd have to throttle the all-core load clocks to 2/3 of the previous value to stay at the same all-core load power. Reply

    It makes sense if you can run a single core at 2.9 GHz, but can run two cores at only 2.7 GHz, and can run four cores at only 2.5 GHz, due to thermal/power limitations. Reply

    These numbers, if they are accurate, clearly suggest 2.9 Ghz single core clocks and a full-core clock for the big core block in the ~2.2 Ghz range. The "small" cores will probably stay at 1.9 Ghz in both single and multi-core, since they are very power efficient. Reply

    But why samsung still use Qualcomm if they have this chip in their sleeve? Reply

    My guess would be verizon/sprint modem patents, maybe its cheaper to put a qualcomm soc in their phone than license those patent. Reply

    As shabby said: CDMA licensing crap, plus the fact that they'd have to build a CDMA2000 stack from the ground up for just for NAM (which afaik is only ~1/3rd of their Galaxy S/Note market), which wouls only be used until 2019-2025 (mostly depending on when Sprint decides to sunset their CDMA2000 network - Verizon has already stated December 2019). Cheaper to just buy some Snapdragon for the NAM folks until they catch up and go all-LTE. Reply
