Dimensity 9000 – MediaTek’s 4nm, 3 GHz octa-core Armv9 processor for flagship 5G smartphones

MediaTek is the top mobile SoC vendor in terms of unit shipped, well ahead of the competition, but the company’s processors were mostly found in entry-level, mid-range, and “premium” smartphones, while flagship smartphones usually feature application processors from  Qualcomm, Samsung, or Apple.

But MediaTek has upped the ante with the introduction of the Dimensity 9000 smartphone processor featuring an octa-core Armv9 CPU subsystem, including one Cortex-X2 core clocked at up to 3.05 GHz, a Mali-G710 MC10 GPU, 5G connectivity, and manufactured with the bleeding edge 4nm TSMC manufacturing process.

MediaTek Dimensity 9000Dimensity 9000 specifications:

  • Octa-core CPU subsystem
    • 1x Arm Cortex-X2 “Ultra Core” at 3.05 GHz
    • 3x Arm Cortex-A710 “Super Cores” at up to 2.85 GHz
    • 4x Arm Cortex-A510 “Efficiency Cores” up to 1.80GHz
    • 8MB L3 cache
  • GPU – Mali-G710 MC10 @ 850 MHz with support for Vulkan, (software) raytracing
  • AI Accelerator – 5th generation APU (AI processing unit) with up to 4x higher power efficiency
  • Memory I/IF – LPDRR5x 7500 Mbps (60 GB/s), LPDRR5 up to 51.2GB/s; 6MB System Cache
  • Storage I/F – TBD
  • Display – Support for FullHD+ display up to 180Hz
  • Camera – 18-bit HDR Imagiq790  ISP with support for up to three 32MP cameras, 320MP single camera, up to 9Gpixels/s
  • Video
    • Decode
      • 8K60 H.265/HEVC, H.264, VP9
      • 8K30 AV1
    • Encode – 8K30 & 4K120 H.265/HEVC, H.264, VP9 (TBC)
  • Wireless connectivity
    • 3GPP Release-16 5G Smartphone Modem
      • 3CC Carrier Aggregation (300MHz)
      • 7Gbps downlink peak performance (using sub-6GHz band)
      • Support for R16 UL Tx Switching for both SUL and NR UL-CA based connections
      • MediaTek 5G UltraSave 2.0 power-saving enhancement suite
    • WiFI 6E 2×2 MIMO
    • Bluetooth 5.3 (Dimensity 9000 is apparently the first SoC to support the latest Bluetooth standard), LE audio-ready
    • GNSS – Beidou III-B1C support (and I suppose the usual GPS, Galileo, GLONASS, but those are not listed)
  • Manufacturing process – TSMC N4 4nm-class process

I mixed the information from MediaTek’s product page and Anandtech to get more complete specifications, but there are still some unknown and points to be confirmed.  With regards to performance, Arm announcement of their Armv8 cores, Arm stated that the Arm Cortex-X2 flagship core would deliver 30% performance improvements over Cortex-X1, the Arm Cortex-A710 “big” CPU core  a 30% energy efficiency gain and more modest 10% uplift in performance compared to Cortex-A78, while the Arm Cortex-A510, high efficiency “LITTLE” Armv9 core would bring up to 35% performance improvements and over 3x uplift in ML performance compared to Cortex-A55.

Dimensity 9000 vs Bionic A15 vs Snapdragon 888
Supposedly Dimensity 9000 vs Bionic A15 vs Bionic A12 vs Snapdragon 888

We also have several comparisons against other flagships devices, courtesy of the Anandtech post, with MediaTek claiming phones based on Dimensity 9000 will have about the same multi-core performance as Apple Bionic A15 based iPhone 13, per GeekBench 5 results, and much better performance than Snapdragon 888 smartphones. MediaTek also claims gaming performance is similar, or even better over a 24-minute period of gameplay, compared to the A15, and power efficiency has been increased by 25% (gaming) to 65% (video playback) against Snapdragon 888. You’ll find more slides about the APU, ISP, etc… shared by MediaTek on Anandtech.

If MediaTek Dimensity 9000 performance and efficiency improvement claims can be eventually verified that means high-performance, yet relatively low power, Arm chips may soon be found in SBCs, mini PCs, systems-on-module, and other embedded hardware. That means Apple may not have an insurmountable lead in the space. This is especially encouraging, as the way I understand it, MediaTek uses Arm’s own Armv9 core without additional customization/optimizations, and others may soon follow suit.

We’re told that Dimensity 9000 is currently shipping, and the first commercial devices are expected by Q1 2022.

MT81xx have gotten a great boost from Chromebooks, they mostly work out of the box by the time hardware gets sold now. If Google decides to put the same amount of pressure on mainlining drivers for phone chips that they have for laptop chips, it won’t even be that hard to do: Dimensity-series MT89xx/MT89xx are closely related to MT81xx, and the overall system design isn’t as complex as the corresponding Qualcomm chips with their many firmware layers.

If they could make another variant for laptops, mini PCs, or the embedded market, then the motivation would probably be much higher.

If they can provide something that can compete on performance against some of the Apple processors, offer a similar or lower price, plus more openness (in terms of supplies), then it would be a winner.

Hey, frankly, rk3588 while not top of the line, will be extremely affordable and powerful for the price.. even if it takes some years to get fully supported on mainline linux, it’s far better than expensive and heavily packed with blobs like any of the high end stuff. Also, for apple silicon, the all attempt to run linux arm there is useless.

The real transition with RPi 4 happened on the main architecture: VideoCore 4 to 6. If Broadcom’s STB (or multimedia or whatever) division will ever do a VC6 on a smaller node, a future RPi will be on this node too with whatever guest processors Broadcom will be choosing.

It’s all about availability of 3rd party’s chips. The 8GB RPi 4 appeared after Micron was able to ship 64Gb LPDDR4 modules. We’ll see a RPi 4 with 16GB once 128Gb LPDDR4 chips are available.

I used to love rpi3, that was my first arm sbc, later on, if you are really interested on arm linux desktop not just retroconsoles like many rpi owners, you find out that rpi lacks of mostly everything you need. I/O, ram bandwidth, gpu, nothing is there. Rk3399 is the closest thing we have today while RK3588 is near to be unveiled.

Also, rpi4 is quite not open source friendly thanks to ThreadX. And the 5v only thingy…. why, why not PD. It would resolve sooo many headaches.

Let’s be honest, RPi4 is their first decent board. I seldom use mine to test code, and build times are bearable. The USB-C connector addressed the issues the micro-USB connector faced. The RAM and I/O bandwidths are low by they made a lot of progress since RPi3. And thanks to modern full-metal enclosures that serve as huge heatsinks, throttling is a thing of the past. I’m not saying the product is awesome, but that it works pretty well and is particularly inexpensive.

Way less contact resistance but especially if you want to power 5V consumers like USB disks by an RPi you still need to be aware that there’s also cable resistance (and their USB-charger a pretty good choice here – also rather inexpensive unlike anything USB PD).

Wrt RK3399 vs. BCM2711 the latter is also more energy efficient than RK3399 fully loaded. Of course RPi 4’s idle consumption could be lower but I guess that’s a challenge when doing USB3 via PCIe.

I noticed this as well and even considered ordering a few more, before I remembered that buying several high-current A-to-C cables instead to connect them to my 5V PSU was even more convenient 🙂

That’s true, my NanoPI-M4 with roughly the same size heat sink (i.e. a thick 1.5cm one taking all the surface of the board) gets hotter than the RPi4 at 2 GHz.

I completely agree with you on the RPi4. I’ve gotten myself two of those (at the same time as I got two 3B boards). I’ve only barely used the 3B boards. For power, I purchased a premium (low resistance) 3m USB-C-to-USB-C cable, cut it in two, and connected them to a MeanWell IRM-60-5ST PSU.

I am not saying that RK3399 is perfect neither, it’s just that it’s better than the pi4 on mostly any aspect. On cpu workloads they are similar in raw performance (some perform better, some worst), but rk3399 have several times more I/O, better gpu, better memory bandwidth, AES, vp8/vp9. And we are talking about an old chip. And it’s more open source friendly than rpi4. You can run it completely blobless if you want. Also, 5v only is the problem, not only the connector. The rockpi4, for example, can work from 5v to 20v (IIRC). If you want to build… Read more »

Odroid N2+ is a monster but still have severe problems.. memory bus, like rpi4 is 32 bit… inside x11 it performs poorly. It have even worse I/O than rpi4.

If you just need a “dumb” monster, it’s great, but it’s still dumb.

That’s why I like the radxa zero, amlogics, are only cool stuff for simple sbcs.. you can’t make anything complex with amlogic (except A311D2) unless you lie like on the odroid N2 and the C4, exposing 4 usb 3.0 when you only have bandwidth for 1.

comparing raw numbers for memory bandwidth that’s about 2.5-3GB/s for S922’s (for a N2.x at blocks of about 10-500MB) and 4.1-4.3GB/s* for rpi4 (8GB ?), but mostly these SBC’s are cpu power limited and memory bandwith limits are not recognizable with consumer usage profiles (www, office tasks, media streaming, video i/o, ‘easy’ object recognition/inference interaction on data input, database analysis?, gaming?, server tasks or network routing? etc.) and that’s around 2002 amd64 (first announcements of amd64/x86-64) desktop level standards.

While thinking about memset values @7.5GB/s = 75Gbit/s = (2.64GT/s) = about 28.4bit/cpu_cycle (11% below theoretical 2x16bit memory interface).

sorry for misunderstanding, again incorrect: interconnector is a term used for bridge connections between transistors on IP implementations (new 2nm example) and also for bus connections between logics ‘clusters’ assembled from IP modules for ARM-related SoCs (or between chiplets on x64 structures).

Me wouldn’t be surprised if an RPi 5 has 64-bit RISC-V guest processors (requires Broadcom going that route of course). This would solve their biggest problem (backwards compatibility with ARMv6/ARMv7) while getting nice press coverage about ‘innovation’ even when performing lower.

If they figure out how to use the XHCI controller inside the BCM2711 maybe we see another RPi 4 with lower idle consumption and USB3 and PCIe usable in parallel? Who knows, who cares?

That’s a wise guess, I tend to agree with you. It will please their fanboys to surf on the “even more open” hype, would save them from offering more performance, and would justify the initial performance losses by “it’s a new product, give it time to mature”. It could be much cheaper and make lots of adepts since day one.

1.) It doesn’t look like they released that info anywhere. The minimum you could expect is 16 GB since that’s what many flagships have, but 18 GB is a possibility since there are a couple phones with that. 20-32 GB, who knows.

MediaTek seems to keep their product lines separate. Like Dimensity in the phones but they are called Kompanio in laptops. They could make tweaks to other versions of the SoC.
