First Armv9 cores unveiled – Cortex-A510, Cortex-A710, Cortex-X2

Armv9 architecture was announced in Q1 2021, building upon Armv8 but adding blocks and instructions for artificial intelligence, security, and “specialized compute”, i.e. hardware accelerators or instructions optimized for specific tasks.

The company has now introduced the first three Armv9 cores with Cortex-X2, Cortex-A710, and Cortex-A510 cores, providing updates to respectively Cortex-X1, Cortex-A78, and Cortex-A55 cores. The company calls those new cores “Arm Total Compute solutions”.

Armv9 Cortex-A510 Cortex-A710 Cortex-X2

Arm Cortex-X2 flagship core is the company’s most powerful CPU so far with 30% performance improvements over Cortex-X1 and will be found in premium smartphones and laptops. Arm Cortex-A710 “big” CPU core provides a 30% energy efficiency gain and 10% uplift in performance compared to Cortex-A78, while Arm Cortex-A510, high efficiency “LITTLE” Armv9 core delivers up to 35% performance improvements and over 3x uplift in ML performance compared to Cortex-A55 announced four years ago, or about the same performance as the “big” Cortex-A73 cores from just a few years ago. Cortex-A510 cores will be used in a broader range of devices from smartphones, to home appliances, and wearable devices.

Since we’ve just mentioned the “big” and “LITTLE” cores, Armv9 still supports DynamIQ technology where big and LITTLE cores work independently wiuth the same SoC. With Armv9 architecture this is handled by the new DynamIQ Shared Unit, DSU-110, supporting up to 8x Cortex-X2 CPUs. Arm also says all new mobile big & LITTLE cores will be 64-bit only in 2023 as previously announced in Arm Roadmap to 2022, but with one year delay. The company also added its global partners will ensure all apps will have 64-bit support by the end of this year to make the 64-bit only transition a seamless experience for consumers.

New Mali G-x10 GPUs and Interconnect for Armv9

Arm Total Compute Solutions

Besides the new Armv9 cores, Arm also introduces four new GPUs:

  • Arm Mali-G710 GPU with the highest performance designed for premium smartphones and Chromebooks. It is said to deliver 20% performance improvements for AAA high-fidelity games and a 35% machine learning uplift for tasks such as image enhancements compared to Mali-G78.
  • Arm Mali-G610 is a “sub-premium GPU” with all the same features as Mali-G710 but at a lower price point. This is an update for Mali-G68 GPU
  • Arm Mali-G510 mid-range GPU offers 100% performance improvements, 22% energy savings for longer battery life, and 100% ML uplift for mid-range smartphones, premium smart TVs, and set-top boxes compared to Arm Mali-G57. That means gaming performance should improve on mid-range devices for larger screens.
  • Arm Mali-G310 entry-level GPU with the highest performance at the smallest area & cost. It will be found in entry-level smartphones, AR devices, and wearables.

In order to connect the Armv9 cores, new GPU, AI accelerator and other IP block, Arm also introduced two new interconnect with CoreLink CI-700 Coherent Interconnect and CoreLink NI-700 Network-on-Chip Interconnect.  Both bring hardware-level support for new Armv9-A features such as Memory Tagging Extension (MTE), as well as improved bandwidth, lower latency, and increased security.

Armv9 SoC’s should be expected in consumer devices by next year. More details may be found on Arm’s CPU and GPU pages, as well as recent posts on Arm community’s processors blog.

I’m looking forward to 2025 when we might see the first Rockchip SoC with 2x A710 and 4x A510 cores, and the first Allwinner SoC with 4x A55.

No, 2025 is in only 4 years, by then we’ll only get the A78 from RK, and Allwinner will have completely dropped ARM and run off single-core 900 MHz RISC-V seconded by a derivative of a 8051 for power management.

Where will the RPI cores be?

The RPI will have 64 cores but they will be Cortex M0+ and people will lap it up.

And all the GPIO, i2c etc will go through a single usb 1 low speed connection.

And you’ll still need closed videocore firmware to boot your 10 assembly instructions LED blinky program.

Raspberry Pi 5 will almost certainly be 4x Cortex-A75 on 28nm.

Why? They just got on 28nm so they probably won’t go lower anytime soon, and Eben Upton trashed the A73 (which has some regressions from A72) in a blog comment.

It’s on the “8GB Raspberry Pi 4 on sale now at $75” blog post from May 28, 2020.

“Actually A73 is a bit of a disappointment. A marginal (<10%) theoretical improvement in power/performance/area over A72, but a well-implemented A72 (which we have) beats an adequately implemented A73 hands down.”

An A72 lacking ARMv8 Crypto Extensions and showing ultra low memory performance. 🙂

“a well implemented A72” ? Seriously ? The Macchiatobin with its A8040 has a well implemented A72. At the same frequency my mcbin compiles 50% faster than the RPi, so there’s definitely a lot of margin left before it can be qualified as “well implemented”. Not even speaking about their lame absence of crypto extensions!

I read somewhere, it would require a Million pound licence fee to add Crypto to their design. The Toaster marketed as RPI4 is a spare parts bin solution. I have no desire to aid or point the solutions out to RPI.

And a Videocore 8 that’s clocked exactly 20% higher than the previous one!

Maybe finally it will be within reach of the lowest end Mali GPU of the previous 2 generations.

I don’t think you can have an A75 (or any later A7x) on 28nm, at least not as hard IP cores. Also, A75 isn’t really enough of an upgrade over A72, unless they double the number of cores, but then the die size and power consumption gets even crazier at 28nm. Cortex-A76 would be the next one that is available as POP IP, but that would require some FinFET process (16nm or below). I’d expect them to stay on 28nm Cortex-A72 for a little longer, and then to move to more (presumably in-order) cores in the future, either Armv9 or… Read more »

Who cares? I will have an RK3588 box in twelve months. This will be good enough for quite some time.

I don’t think they will ever release it. RK3588 is just steam and it’s been since the day they made that presentation. Or maybe they will, in 2024, when the SoC is on par with the very low budget smartphones. It will be released EXACTLY when you don’t feel it appealing anymore.

And the 8051 will be running a RISC-V software emulator because trying to code for the 8051 is like putting your own hand into a meat grinder..

But who could possibly use more than 256 bytes of RAM?

With that said, 8051 was really easy to code for, being a CISC it did have useful instructions like MUL, DIV and others that used to be missing from much more recent cores. Interrupt handling was ugly but convenient and resource-saving. And it was dog slow but BASIC ran on it 🙂

Interrupt handling ugly ? sorry for me the nested interrupt handling of MCS-51 core was a boon , later even more recent 8 bit architectures like AVR etc and not so recent PIC (Mid range and higher architecture) were lacking in this feature .Last decade saw few more enhanced single cycle 1T type MCS-51 cores coming and those again helped retained the old 8051 legacy specially many Chinese MCU vendors now offers hundreds of these new core based MCUs (with lots and lots of other enhanced peripherals )at throw away prices.

Too bad Huawei (HiSilicon) has been locked out. Otherwise we could have a taste of the new cores in their flagship Mate-Series at the end of this year instead, as they were always the quickest to implement ARM new cores.

No? Their SoCs always had older CPUs. They were always the fastest to implement on a new litographs

They were always the fastest to implement ARM new cores until they are not because they were left with only lisence for A76 core (and A55) when ARM stopped all technical relationship with them. Not too long after that they were even pushed out of TSMC. Thanks to Trump for both problems.

The improvements in the low end A510 and G310 are what make me happiest in all of this–as they’re the parts we’re most likely to see trickle down to cheap SBCs. The performance/power improvements in them are the best of the announcement.

If you look into it, A510 doesn’t seem to offer much until it reaches higher frequencies, although that might be acceptable for SBCs. See AnandTech’s article about the announcement.

The Mali GPUs look a lot better but I didn’t pay much attention to it.

We’re still looking at area improvements as well as memory interface improvements for the A510. The dual/cluster thing will be interesting. I see it more as a bridge until people start doing a lot of ML codes. Sharing the vector unit for now and then splitting it in the future. Should provide a lot of flexability for implementors. But probably a pain for us users to figure out what a chip really looks like. 😉

Sadly, there is no such thing as cheap boards anymore. The old times where you could get one for 20-25€ including shipping are gone. I’ve moved to second hand mini x86 computers for the time being, they cost just a little more than the current overpriced boards(*cough* COVID excuse *cough*) and they offer more versatility. If I have to spend 50€+ on a board, I just don’t do.

Oddly apart from a fab fire and a couple of other problems, there are more chips being made than ever. Demand has rocketed and lead time for being fabbed has gotten much longer. The short term answer, would be to over clock higher and fit a larger area ( heat radiation surface ) heatsink. Medium term, Smartphone SoC design should be more modular, so as the SoC falls from Smartphone market the IP is adapted to HDMI output and TV / TV box. Longer term the phone will be the TV player and Smartphone. Plug the phone into a cradle… Read more »
