MediaTek Announces Dimensions 1100 and 1200 SoCs: A78 at 6nm


Today MediaTek announced two new top-end SoCs as the new Dimension 1100 and Dimension 1200. The two new designs are a follow-up to last year’s Dimension 1000 SoC, marking the company’s return to high-end in 2020. A relatively solid SoC design.

Two new chipsets upgrade the Dimension 1000 in terms of CPU configuration and camera capability, as well as the new 6nm process node. However, the new chips do not upgrade every aspect of their design, as things like the GPU configuration and modem capabilities are similar to the Dimension 1000.

Starting with where we see the biggest changes, the two new SoCs are the most different from their predecessors on the CPU side of things. The Dimension 1100 is quite straightforward in that it replaces the Cortex-A77 core with the new Cortex-A78 core. The configuration is still running on 4 cores. Running at 2.6GHz (high-bin amplitude as 1000+), with four Cortex-A55 cores as 2.0GHz small cores.

The Dimension 1200 changes the configuration to a 1 + 3 + 4 setup, with a performance Cortex-A78 core running up to 3.0GHz, and MediaTek said it doubles the L2 cache compared to other cores. This would mean that it has a 512KB configuration while the other 3 cores feature a 256KB L2. There is also a 1 + 3 large core setup with 4x Cortex-A55 cores at 2GHz.

The GPU side of things is a bit weird, as strangely as it does the exact same setup as the Dimension 1000, and we again see a Mali-G77 MP9 configuration on both new chipsets. This is very strange given the fact that other competing chipsets are deploying the new Mali-G78 design.

DRD capability at 2133 MHz remains on LPDDR4X – the lack of LPDDR5 is not too surprising here as the performance gains are not great and these chipset designs are to be used in more cost-effective devices.

The NPU and AI capabilities are not at all clear on the Dimension 1100 and seem to be identical to the Dimension 1000 – the Dimension 1200 offers a performance boost of 12.5% ​​which may be a slight clock frequency upgrade compared to its predecessor.

On camera capabilities, the new chips do not change their multi-camera configurations, yet happening at 32 + 16MP, although both increase the single-camera ad capability to 108MP and 200MP for the Dimension 1100 and Dimension 1200, respectively.

On the 5G modem side, we are not seeing any obvious changes in specifications supported by the new design, it is still a sub-6GHz implementation.

The new chip is built on a new 6nm process node at TSMC – a design-rule compatible shrink compared to the 7nm node that was used in the Dimension 1000.

Both are Dimension 1100, Dimension 1200, rather odd SoC designs, in that they are smaller upgrades than their predecessor – in reality one would think they are just a minor refresh on their predecessor’s ground-up redesign. It is very strange to see very small feature disparity between 1100 and 1200, even though these must be different chip designs and tape-outs given their CPU differences. The fact that MediaTek did not upgrade the NPU / APU or GPU to any substantial extent also indicates that these will be small design upgrades rather than the previous generation. This is not really a negative in itself, but the question is what is MediaTek’s market plan for the new SoCs.

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