Today MediaTek revealed two brand-new top-end SoCs in the form of the new Dimensity 1100 and Dimensity 1200. The two new styles are a follow-up to in 2015s Dimensity 1000 SoC which marked the businesss go back to the high-end in 2020, with a fairly solid SoC style.

The 2 new chipsets update the Dimensity 1000 in terms of CPU configuration and electronic camera ability, as well as coming in a new 6nm process node. The brand-new chips nevertheless dont upgrade every element of their designs, as things such as the GPU configuration and the modem capabilities seem to be similar to that of the Dimensity 1000.

The Dimensity 1200 changes the configuration to a 1 +3 +4 setup, with one performance Cortex-A78 core clocking up to 3.0 GHz, and MediaTek specifying that it sports double the L2 cache compared to the other cores. Both Dimensity 1100 are Dimensity 1200 are rather odd SoC designs in that they are rather little upgrades compared to their predecessor– in fact looking at them one would believe they are just minor refreshes on the ground-up redesign of their predecessor.

Starting off where we see the most significant modifications, the two brand-new SoCs vary the most from its predecessor on the CPU side of things. The Dimensity 1100 is rather uncomplicated in that it changes the Cortex-A77 cores with more recent Cortex-A78 cores. The setup still remains at 4 cores running at 2.6 GHz (as the higher-bin Dimensity 1000+), with 4 Cortex-A55 cores at 2.0 GHz as the little cores.

On the 5G modem side, were seeing no obvious modifications in the specs supported by the new style, it still being a sub-6GHz just execution.

On the video camera capabilities, the brand-new chips dont change their multi-camera configurations, still being at 32 +16 MP, nevertheless both increase the single-camera advertised ability approximately respectively 108MP and 200MP for the Dimensity 1100 and Dimensity 1200.

DRAM capability stays at LPDDR4X at 2133MHz– the absence of LPDDR5 isnt too unexpected here provided the efficiency gains arent undue and these chipset designs are to be used in more cost-effective gadgets.

The Dimensity 1200 modifications the configuration to a 1 +3 +4 setup, with one efficiency Cortex-A78 core clocking up to 3.0 GHz, and MediaTek specifying that it sports double the L2 cache compared to the other cores. This would imply it has a 512KB configuration while the other 3 cores feature 256KB L2s. The 1 +3 huge cores setup is likewise accompanied by 4x Cortex-A55 cores at 2GHz.

The new chip is produced on a brand-new 6nm process node at TSMC– a design-rule compatible shrink compared to the 7nm node that was utilized in the Dimensity 1000.

The GPU side of things is a bit unusual, as strangely adequate it features the exact very same setup as the Dimensity 1000, and we once again see a Mali-G77MP9 configuration on both new chipsets. Thats really odd given the truth that other rival chipsets are deploying new Mali-G78 styles.

MediaTek prices estimate vendors such as Xiaomi, Vivo, OPPO and realme as expressing support for the new SoCs, with devices using both SoCs being expected to be readily available at the end of Q1 and start of Q2 this year.

Starting where we see the greatest changes, the 2 brand-new SoCs vary the most from its predecessor on the CPU side of things. The Dimensity 1100 is rather simple because it replaces the Cortex-A77 cores with newer Cortex-A78 cores. The setup still stays at 4 cores running at 2.6 GHz (as the higher-bin Dimensity 1000+), with four Cortex-A55 cores at 2.0 GHz as the little cores.

NPU and AI abilities arent exactly clear on the Dimensity 1100 and it seems to be identical to that of the Dimensity 1000– the Dimensity 1200 promotes a performance boost of 12.5% which might just be a minor clock frequency upgrade compared to its predecessor.

Both Dimensity 1100 are Dimensity 1200 are rather odd SoC designs in that they are rather small upgrades compared to their predecessor– in truth looking at them one would believe they are just minor refreshes on the ground-up redesign of their predecessor. Thats not actually an unfavorable in itself, but it begs the question what MediaTeks market plan for the brand-new SoCs are.
