MediaTek Dimensity 900 6nm SoC brings UFS 3.1, LPDDR5 to mid-range 5G smartphones

Arm Cortex-A78 and LPDDR5 would have been premium features not so long ago, but time flies, and the just-announced MediaTek Dimensity 900 5G SoC for mid-range smartphones includes two Cortex-A78 cores, six Cortex-A55 cores, support for LPDRR5/4 memory, UFS 3.1 storage, and of course 5G cellular connectivity up to 2.77Gbps.

That means Dimensity 900 “mid-range” processor is now basically better than the Dimensity 1000 “premium” SoC announced at the end of 2019, except for 4Kp60 support and the faster 4.7Gbps 5G download speed.

The new MediaTek Dimensity 900 is expected to found in smartphones launched in Q2 2021, which would be this month or next. More details may be found on the product page and press release.

  1. Is it just me or is 2520×1080 a bit low for display capability? No 1440p.

    I’ve seen this on other MediaTek SoCs, e.g. MT8183 does 2400×1080.

    1. If you look to Samsung and Sony phones yes but they iirc run at a lower resolution (720 or 1080) most of the time and only use native resolution for videos. Is there much benefit from going over 1080 and is it enough to offset the extra battery drain?

      1. I guess 1440p doesn’t exist in the mid-range, just previous flagships.

        I was also wondering if MediaTek would put Dimensity in laptops, but I don’t see any evidence of them doing that.

  2. Yeah time just flies for the Linux SBC world as well — as we wait for affordable SOC’s past cortex-a73 with mainline support.
