Allwinner A733 is an octa-core Cortex-A76/A55 processor with an optional 3 TOPS NPU and support for up to 16GB RAM designed for Android 15 tablets and laptops such as the Teclast P50Ai with a 10.92-inch touchscreen display.
With two Cortex-A76 cores, six Cortex-A75 cores, an Imagination BXM-4-64 MC1 GPU, and an NPU, the Allwinner A733 looks very similar to the Allwinner A736 we noted in a roadmap last year. But there’s no news about the A736, so maybe the name was dropped and the Allwinner A733 was launched instead.

The information mostly comes from a blog post on Olimex, but also from GeekBench for CPU frequencies and the Teclast P50Ai product page. The latter mentions “Max 16GB RAM (6GB+10GB Expansion)” which means 6GB LPDDR5 plus 10GB virtual memory (swap on UFS storage?), so you have to be careful when purchasing devices expecting to get 16GB of actual RAM…
In terms of performance, the Allwinner A733-powered Teclast P50AI tablet gets 320,000 points in the Antutu benchmark which compares to 400,000 points for the MediaTek Helio G99 with a similar 2x Cortex-A76 + 6x Cortex-A55 design but slightly higher CPU frequencies (2.2GHz and 2.0GHz) and an Arm Mali-G57 MC2 GPU.
Olimex also mentions three versions are available:
- Allwinner A733MX-HN3 with NPU and HDMI output
- Allwinner A733MX-N3X with NPU, but no HDMI output
- Alwinner A733MX-HXX with HDMI output, but no NPU
We don’t have pricing for the Allwinner A733 itself, but for reference, the Teclast P50Ai tablet sells for $129 on AliExpress with 6GB LPDDR5 and a 128GB UFS 3.0 flash. Besides Android hardware, we could potentially have Linux hardware too since Olimex plans to update their open-source hardware “TERES-I” DIY laptop with Allwinner A733 SoC and up to 16GB RAM, which would be a nice upgrade from the 1.2 GHz Allwinner A64 quad-core Cortex-A53 processor with 2GB DDR3L RAM and 16 GB eMMC Flash. So stay tuned…

It would be nice upgrade for Olimex laptop or SBC.
Finally, a budget product with a full function USB-C port (10Gb too) with video out and the other that can be used to charge at the same time when connected to a monitor. It’s definitely not the fastest by any stretch but I suspect that it might be a reasonable daily all rounder. From what I can make out though, the screen is only 720p, which the Aliexpress link seems to avoid mentioning. But at a price of £105 right now, I may well go for one and carry out a review to see if it is the bargain that… Read more »

Thanks.
That’s a really weak GPU, isn’t it?
It was mid-range in 2020 according to Imagination. It looks slower than Arm Mali-G57 MC2 based on the overall Antutu score. It’s suitable for user interfaces, but probably not ideal for gaming.
Allwinner A838 octa-core processor with four Arm Cortex-A78 cores, four Arm Cortex-A55 cores, 64-bit RAM, UFS 4.0 storage, and a 10+ TOPS NPU is coming at the end of 2025 or beginning of 2026. I don’t have more details now. Just an Allwinner 2024-2026 roadmap.
I’ve been told Allwinner is eager to return to the “open source market” following the success of the Rockchip RK3588 solutions, and processors like the A733 and A838 are part of that.
I’ve also learned Rockchip is not selling the RK3588 directly to SBC vendors and stopped contributing code to the open-source community. The situation allegedly happened because some RK3588(S) SBCs are used in drones used in the military conflict in Ukraine (as reported in social networks a few months ago), and Rockchip doesn’t want to take the risk of being sanctioned.
If that’s true, it’s ridiculous and a huge hypocrisy. It just means that their chips will still be used for these devices, but sold at a much higher price to intermediary companies dedicated to that task. In short, they’re just trying to make much more money from this situation and pretending they don’t want to have any relation with it. And what a better opportunity to stop offering the very basic support to those having been doing their integration work for free into the kernel ? They’ve never made much effort in this direction anyway. I hope that’s not the… Read more »
Its not true or at least the non contribution isn’t.
That was a Rockchip contrib a few days ago

This is not 100% correct. Sure Rockchip restricted selling chips. But Rockchip is for sure is still contributing mainline code to 358X and 357X too. We see comment and patches from their devs almost daily in rockchip mainline mailing list.
Lets get the facts straight – RochChip only restricted who they are selling RK3588 chips to.
