[Anandtech.com] Samsung Announces New 9810 SoC: DynamiQ & 3rd Gen CPU


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.

Process Samsung
10nm LPP Samsung
10nm LPE 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 ISO-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.

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 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.


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.
