Samsung Exynos 2100 5G mobile SoC offers Cortex-X1 core, LPDDR5 memory and more

Following the introduction of Qualcomm Snapdragon 888 5G premium processor last December, Samsung has now unveiled the Exynos 2100 5G mobile SoC with many of the same features and specifications.

The new 5G processor notable features a similar eight-core design with one Cortex-X1 core, three Cortex-A78 cores, and four low-power Cortex-A55 cores, 26 TOPS of AI computing, support for 4K UHD displays, as well as a 5G modem built into the chip.

The Arm Cortex-X1 core boosts single-core performance by up to 19%, while multi-core performance gets improved by up to to 33%, and the Mali-G78 MP14 GPU offers up 46% faster graphics performance compared to the Mali-G77 MP11 GPU found in Exynos 990.

If we look at Snapdragon 888 specifications all features are virtually the same, up to the 5nm Samsung manufacturing process using in both processors. It’s almost like both companies worked together… The main difference may be the Mali-G78 MP14 GPU against the  Adreno 660 GPU.

Samsung says the Exynos 2100 is currently in mass production. More information may be found in the awful “modern” product page where you have to continuously scroll to get tidbits of information coming at a time.

  1. Anybody know size of cortex-x1 and cortex-a78.
    As I really don’t understand why they can’t put 4xcortex-x1 and they are mixing 3 different types of cores

    1. I can think of two reasons:

      1. The cost of the Cortex-X1 is probably high
      2. Cortex-X1 is used for single threaded tasks, four had to run at the same time there may be cooling issues/thermal throttling, plus it’s not optimized for power consumption.
    2. AnandTech guessed that X1 is 50% larger than A78, for about 20% extra performance. But I see only “15% more silicon area” on WikiChip, which would be a pretty good deal if correct.

      How about 2x Cortex-X1, 6x Cortex-A55?
