Samsung debuts flagship ‘Exynos 990’ processor, probably for the Galaxy S11

Hot on the heels of Huawei’s Kirin 990 flagchip launch a month ago, Samsung has announced their own next-gen Exynos processor with up to 20% better performance for use in next year’s Galaxy S11 series… also called the ‘990’.

Anticipating the launch of their next-gen flagship Galaxy S11 family of smartphones next year (or whatever they decide to call it), and not to feel outdone by Huawei’s already-launched Kirin 990 and 990 5G found in their Mate 30 series, Samsung has just unveiled their bid for the 2020 flagship processor game; the ‘990’… the Exynos 990 that is.

Built on Samsung’s new 7nm EUV lithography, the same as Huawei’s aforementioned Kirin 990, the Exynos 990 should be significantly more efficient than the current flagchip Exynos 9820 built on Samsung’s 8nm LPP, which was a refined 10nm, especially when combined with claimed efficiency improvements in the core architecture.

To those cores themselves, though, and the Exynos 990 is sporting a tri-layer design with the classic staple Cortex A76 core we’ve seen in the all other flagchips so far, however it tops it with some sort of custom ‘Mongoose 5’ code which Samsung claims a 20% performance improvement over the M4 with, which was roughly equivalent to the same Cortex A76; my guess is that the M5 is a derivative of ARM‘s Cortex A77, since Samsung has said they’re ditching custom designs now, or at least roughly equivalent in performance.

And to the Exynos 990’s GPU, we’re seeing Samsung utilising ARM’s newest Mali G77 architecture, though with one fewer core than the Exynos 9820, which the company claims will provide a 20% boost to gaming and any other GPU-intensive tasks aided by the G77’s new ‘Valhalla’ design.

We’re also seeing Samsung claim an enormous 10TOPs of neural processing power in the Exynos 990, which should speed up certain features in the phone such as scene recognition and perhaps some pattern recognition algorithms.

Penultimately, Samsung has also hugely improved the memory subsystem with the Exynos 990 being perhaps the first mobile chipset to support LPDDR5 memory, which is unlikely to provide any noticeable performance benefit but is nevertheless a great new technology.

And finally, Samsung has confirmed that the Exynos 990 will support camera systems of up to the ridiculous 108MP size – an imaging sensor only Samsung themselves yet offers – which is to me essentially a confirmation that the Galaxy S11 will use that 1/1.33inch 108MP Samsung ISOCELL HMX image sensor.

There’s also the curious fact that the Exynos 990 doesn’t sport an integrated wireless modem unlike all other chipsets of the last few generations. Instead, Samsung is simultaneously launching the ‘Exynos 5123’ external 5G modem, which all Exynos 990 phones will use, with blazing fast theoretical speeds in both 4G LTE and 5G settings.

The Exynos 990 will likely be given a solid run for its money with the upcoming Snapdragon 865 tipped to support ARM’s latest core designs combined with Qualcomm’s own leading graphics technologies, but it is nonetheless an extremely powerful and feature-rich processor for the next generation of smartphones.
