MediaTek Announces Dimensity 1000 SoC: Back To The High-End With 5G
Today MediaTek is announcing the new Dimensity 1000 SoC – the company’s new 5G flagship SoC for 2019 and early 2020. The announcement really isn’t too much of a surprising new reveal, as the “5G SoC” was announced some time ago in May with the company describing its 5G capabilities as well as the inclusion of the new Cortex-A77 and Mali-G77 IPs. What MediaTek does today however is to officially name the new chipset, and go into a few more details on the specifications.
First of all, the naming of the chipset is part of rebrand for the company’s SoC line-up going forward. The “Dimensity” name is meant to usher in a new generation and differentiate the new 5G SoC from the previous 4G Helio line-up.
“We chose the name Dimensity to highlight how our 5G solutions are driving new waves of innovation and experiences, much like the fabled fifth dimension,”
– MediaTek President Joe Chen.

At the heart of the Dimensity SoC lies the new Cortex-A77 CPU. MediaTek was notoriously first to announce a product based on the new IP, only days after Arm had themselves publicly revealed the new microarchitecture. Today MediaTek goes into more detail, and explains that the CPU configuration on the Dimensity 1000 (Let’s just call it the D1000) is a 4x Cortex-A77 setup running at 2.6GHz alongside 4x Cortex-A55’s at 2.0GHz. The 2.6GHz clock rate is pretty much spot on where we expected the first A77 configuration to land at, and should make the D1000 extremely competitive on the high-end of the SoC market.
The fact that this is a SoC with 4 big cores further enforces the notion that this is a flagship chip, and is a departure from MediaTek’s CPU strategy of the previous few years. The SoC also employs a new Mali-G77 GPU, however we currently don’t have further information on the core count or frequencies of the part.
MediaTek also employs its own third-generation neural processing unit which it calls “APU 3.0”. It says it’s able to double the performance over its previous generation chipsets. MediaTek fared quite well in some benchmarks here due to its quite complete software stack supporting all the new NNAPI features, whilst other vendors such as Qualcomm or Samsung still have incomplete solutions.
We don’t have details on the memory support, but it’s unlikely that we’ll see LPDDR5 supported (MediaTek would have surely mentioned it), so we expect LP4.
ISP capabilities have been improved and the new SoC will support camera sensors with resolutions of up to 80MP at 24fps, or multi-camera setups with 32+16MP sensors. Media encoding capabilities fall in at 4K60.
Most importantly what justifies the Dimensity 1000 adopting a whole new branding is the fact that it’s a 5G with a new integrated modem. MediaTek discloses it supports 5G Sub-6 in both SA and NSA, and is capable of download speeds of up to 4600Mbps thanks to 2x carrier aggregation, as well as upload speeds of up to 2500Mbps. We currently don’t have information on the 4G capabilities and if the carrier aggregation differs to the 5G abilities.
MediaTek describes its 5G modem implementation as extremely power efficient and claims it’s ahead of competing solutions in this regard, an interesting claim which hopefully we’ll maybe get to test in 2020.
The company says we’ll be seeing devices based on the new chipset later this year as well as in early 2020. Overall, it seems like MediaTek’s new push into 5G is a bigger than usual effort to try to re-enter the flagship device market, and based on pricing, the Dimensity 1000 should end up as a competitive offering.
