Spreadtrum SC9863 Octa-core Cortex A55 Processor is Made for LTE Smartphones

Arm unveiled Cortex A55 cores about a year ago, and while we have seen the new cores combined with Cortex 75-class cores in premium smartphone processors such as Exynos 9810 SoC, I had yet to see a standalone Cortex A55 processor that should deliver a performance boost compared to A53, while keeping the costs in check, and providing good power efficiency.

Spreadtrum has filled this void with their SC9863 processor equipped with eight Cortex A55 cores clocked a 1.6 GHz, and designed for LTE smartphones.

Performance is said to be improved by 20% compared with their Arm Cortex-A53 processor, and the SoC also embeds an AI processing unit that increases AI tasks performance by 6 times, and allows for real-time intelligent context detection and recognition, AR photography, and face recognition.

Spreadtrum SC9863 also features a dual ISP capable of handle dual cameras of up to 16 MP, supports 1080p HD video playback as well as FHD+ (1080*2160) screen displays.

The processor also comes with connectivity features via a five-mode full-band LTE Cat 7 modem supporting carrier aggregation and TDD/FDD hybrid networking, as well as dual-card dual-VoLTE and VoWiFi.

That’s about all we know since the product page is not up just yet, and all information was taken out from the press release.

Is it known what process these chips are produced?

at least 14nm, I don’t think any a55 is gonna exist in anything higher than that. Anyways, if it were the case it would be nonsense to have an energy efficient a55 with 28nm fab since there are some a53 socs made in 20nm or even 14nm, which would cause those to be more energy efficent than the a55’s.

But thinking about this spreadtrum soc, it is going to be very efficient if it is really clocked at 1,6ghz, that’s pretty low for a 14nm soc.

I was just reading up on Spreadtrum, after your article and they have more success in low end range less success in mid range, and less top range success with their octacore versions of Intel’s Atom SoCs, using eight Airmont cores. So which market range are they aiming this at, I wonder?

Anyone wanting A55 and A75 catch up, I would recommend this webpage and the two videos by Gary, I respect his pedagogy eduction style, having pedagogy training myself too

I think the snapdragon 636 is a (mildly customized) octa core a55 and benchmarks surprisingly well

It is not. [4 x Cortex-A73] + [4 x Cortex-A53], slightly customized according to “Built on ARM Cortex” license.

That’s the 660,the 636 is another beast entirely

Snapdragon 636 is an underclocked version of the Snapdragon 660.
BTW, you can compare 636 with 652 in Geekbench 4 single-core benchmark. They are almost the same.

Are thinking of these?

” The six low-powered cores are a tweaked version of the ARM Cortex-A55 called ‘Kryo 300 Silver’ clocked at a maximum of 1.7GHz”

The kryo 300 silver?

“… Cortex A533 …” Typo.
from context i get its Cortex A55
