MediaTek launches Dimensity 1100 and 1200 chips

It seems that just a few weeks ago MediaTek was launching another 5G chip (oh wait, it was) but this time we’re talking about the other end of the spectrum, the Dimensity 1200 is the flagship Dimensity chip, replacing the Dimensity 1000+, but we also have the Dimenisty 1100, a slight step down from the 1200, but still an incredibly high-end chip.

Dimensity 1200 launch

  • Dimensity 1200
  • Dimensity 1100
  • Dimensity 1000+
  • CPU – 1x Cortex A78 @ 3.0Ghz, 3x Cortex A78 @ 2.6Ghz, 4x Cortex A55 @ 2.0Ghz
  • GPU – Mali G77 MC9
  • Process – TSMC 6nm
  • RAM – 4 Channel LPDDR4X-4267
  • Modem – MTK M70
  • Display Support – QHD @ 90Hz / 1080+ @ 168Hz
  • Video Encode – 4K60 10bit, H.264,H.265/HEVC
  • Video Decode – AV1, 4K60 H.265, H.264
  • CPU – 4x Cortex A78 @ 2.6Ghz, 4x Cortex A55: 2.0Ghz
  • GPU – Mali G77 MC9
  • Process – TSMC 6nm
  • RAM – 4 Channel LPDDR4X-4267
  • Modem – MTK M70
  • Display Support – QHD @ 90Hz / 1080+ @ 168Hz
  • Video Encode – 4K60 10bit, H.264,H.265/HEVC
  • Video Decode – AV1, 4K60 H.265, H.264
  • CPU – 4x Cortex A77 @ 2.6Ghz, 4x Cortex A55 @ 2.0Ghz
  • GPU – Mali G77 MC9
  • Process – TSMC 7nm
  • RAM – 4 Channel LPDDR4X-3733
  • Modem – MTK M70
  • Display Support – 1080+ @ 144Hz
  • Video Encode – 4K60, H.264, H.265/HEVC
  • Video Decode – AV1, H.264,H.265/HEVC, VP9

So the Dimensity 1100 is the real successor to the 1000+, swaps the A77’s or A78’s, goes form TSMC 7nm to TSMC 6nm, slightly faster RAM, support for high refresh QHD screens and 4K60 10bit video recording. The Dimensity 1200 is interesting because it adopts the new core architecture that Qualcomm and HiSilicon have been doing, you have one core at a higher clock speed (and often times voltage plane) this is your “prime” core, the core that single threads go to, then you have 3 high performances cores but slower than Prime, then you have the efficiency cores, these are still Cortex A55 as there is nothing newer at this time.

The Dimensity 1100 and 1200 are both being made on TSMC’s 6nm fabrication facility. Unlike its 5nm node, 6nm from TSMC is just a much more optimised production process, not a full node shrink, we get 18% higher logic (transistor) density over TSMCs N7 7nm node, whilst keeping the same power requirements and higher performance. What’s coolest though is that N6 uses the same design libraries as N7 so theoretically a company using N7 for a product can switch over to N6 for increased density (Smaller chips) lower power, and with minimal redesigns needed.

Dimensity 1200 Launch

The Dimensity 1100 and 1200 chips are going to be MediaTek’s flagship chips for 2021, whilst it is a bit upsetting to not see Cortex X1, Mali G78, or TSMC/Samsung 5nm, I’m actually very happy with that MediaTek has shown here, it is got a top-shelf 5G modem integrated into the SoC, the cortex A78 is no slouch and TSMCs 6nm still brings a nice improvement on PPA versus it is 7nm that the previous chips were built on, we hope to see announcements in the near future of devices using the 1100 and 1200 as that was the upsetting thing about the 1000 series last time, almost no one used it.
