The two new chipsets update the Dimensity 1000 in regards to CPU setup and electronic camera capability, along with being available in a brand-new 6nm process node. The new chips nevertheless do not update every aspect of their designs, as things such as the GPU configuration and the modem abilities seem to be identical to that of the Dimensity 1000.

Today MediaTek announced two brand-new top-end SoCs in the kind of the new Dimensity 1100 and Dimensity 1200. The 2 new designs are a follow-up to in 2015s Dimensity 1000 SoC which marked the businesss go back to the high-end in 2020, with a relatively strong SoC design.

MediaTek estimates vendors such as Xiaomi, Vivo, OPPO and realme as expressing support for the brand-new SoCs, with gadgets using both SoCs being expected to be available at the end of Q1 and beginning of Q2 this year.

On the 5G modem side, were seeing no obvious modifications in the specifications supported by the brand-new design, it still being a sub-6GHz only implementation.

NPU and AI capabilities arent exactly clear on the Dimensity 1100 and it appears to be similar to that of the Dimensity 1000– the Dimensity 1200 advertises an efficiency increase of 12.5% which could just be a small clock frequency upgrade compared to its predecessor.

The Dimensity 1200 modifications the setup 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 small 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.

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

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

Starting off where we see the greatest modifications, the two brand-new SoCs vary the most from its predecessor on the CPU side of things. The Dimensity 1100 is quite uncomplicated in that it changes the Cortex-A77 cores with newer Cortex-A78 cores. The configuration 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.

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

On the cam abilities, the brand-new chips dont change their multi-camera setups, still being at 32 +16 MP, nevertheless both increase the single-camera marketed ability as much as respectively 108MP and 200MP for the Dimensity 1100 and Dimensity 1200.

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 think they are just small refreshes on the ground-up redesign of their predecessor. Thats not truly an unfavorable in itself, however it pleads the concern what MediaTeks market strategy for the brand-new SoCs are.

Beginning where we see the greatest modifications, the 2 brand-new SoCs differ the most from its predecessor on the CPU side of things. The Dimensity 1100 is rather straightforward in that it changes the Cortex-A77 cores with more recent Cortex-A78 cores. The configuration still remains 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.

DRAM ability stays at LPDDR4X at 2133MHz– the absence of LPDDR5 isnt too unexpected here provided the efficiency gains arent too fantastic and these chipset styles are to be used in more economical devices.
